Low ESG-consumption effect: How Do Consumers Use Firm Disclosure? Evidence from a Randomized Field Experiment by Sinja Leonelli, Maximilian Muhn, Thomas Rauter, and Gurpal Sran as of Jan. 11th, 2024 (#79): “In a sample of more than 24,000 U.S. households, we first establish several stylized facts: (i) the average consumer has a moderate preference to purchase from ESG-responsible firms; (ii) consumers typically have no preference for more or less profitable firms; (iii) consumers rarely consult ESG reports and virtually never use financial reports to inform their purchase decisions. … Consumers increase their purchase intent when exogenously presented with firm-disclosed positive signals about environmental, social, and—to a lesser extent—governance activities. Full ESG reports only have an impact on consumers who choose to view them, whereas financial reports and earnings information do not have an effect. After the experiment, consumers increase their actual product purchases, but these effects are small, short-lived, and only materialize for viewed ESG reports and positive social signals. … we provide explanations for why consumers (do not) change their shopping behavior after our information experiment“ (abstract).

ESG data criticism: ESG Data Primer: Current Usage & Future Applications by Tifanny Hendratama, David C. Broadstock, and Johan Sulaeman as of Jan. 12th, 2024 (#66): “ESG data is important, and will become even more so as time progresses. … There remains a prevalent use of combined ESG scores instead of E, S and G specific pillar scores; The use of combined ESG, and pillar specific scores may themselves detract focus away from crucial underlying raw data; Empirical research depends heavily on a small number of ESG data providers; That some data providers focus more on the E than the S – creating a need for data users to make sure the scoring ethos of each provider aligns with their expectations and requirements; There is a potentially material quantity of ESG data inconsistencies which could result in unintended investment allocation” (p. iv). My comment: I use segregated E, S and G ratings since many years and best-in-universe instead of best-in-class ratings

Costly washing: ESG washing: when cheap talk is not cheap! by Najah Attig and Abdlmutaleb Boshanna as of Dec. 26th, 2023 (#63): “… we introduce an easily replicable ESG washing measure. We then document a robust negative impact of ESG washing on corporate financial performance … we show that the COVID-19 pandemic incentivized firms to engage in increased overselling of their ESG performance. Taken together, our new evidence suggests that ‚cheap talk is not cheap‘ and the misalignment between ‘ESG talk’ and ‘ESG walk’ not only fails to serve shareholders‘ best interests but may also undermine a firm’s social license to operate” (abstract).

Disclosure or performance? The relation between environmental performance and environmental disclosure: A critical review of the performance measures used by Thomas Thijssens as of Jan. 9th, 2024 (#8): “More extensive disclosures may even be a signal for inferior rather than superior performance in terms of actual environmental impact. This suggestion is fueled by the observations that more polluting industries have on average more extensive ED (Sö: Environmental disclosure) and higher environmental commitment is associated with higher GHG emissions“ (p. 18). My comment: Most other studies known to me show – in general – positive effects of more disclosure

Performance-neutral ESG: Drawing Up the Bill: Is ESG Related to Stock Returns Around the World? by Rómulo Alves, Philipp Krüger, and Mathijs van Dijk as of Jan. 13th, 2024 (#47): “… our analysis of a comprehensive global database (including 16,000+ stocks in 48 countries and seven different ESG rating providers over 2001-2020) uncovers very little evidence that ESG ratings are related to stock returns around the world. … thus it has been possible to “do good without doing poorly.” Our findings also suggest that the prices of strong ESG stocks have not consistently been driven up, and that, going forward, ESG investors could potentially still benefit from any demand effects resulting in the pricing of ESG preferences. On the flip side, our analysis implies that ESG investing has so far not been effective in reducing (increasing) the cost of equity capital of strong (poor) ESG firms, which could lead firms to internalize climate and social externalities (Fama 2021, Pástor et al. 2021)“ (p. 14). My comment: I could not agree more for the small and midcap companies on which I focus

Huge climate risks: How climate stress test may underestimate financial losses from physical climate risks by a factor of 2-3x by Jakob Thomä from 1 in 1000 and Theia Finance Labs as of Dec. 1st, 2023: “A high baseline climate risk (i.e. using a climate stress-test model with meaningful baseline GDP losses over the next 30 years) stress-test scenario can create a 10% shock to global equity markets. A combination of climate tipping points, ecosystem decline, and social risks can increase that number as a cumulative risk to 27%, almost 3x the baseline losses. A low baseline scenario of a 4% shock in turn turns into a 14% shock when considering these other factors. These losses are dramatic as they are secular and not cyclical. It is worth flagging that this event would be unprecedented in modern financial market history“ (p. 4). My comment: Thanks to Bernd Spendig for informing me about this study.

Climate risk aversion: Institutionelle Investor:innen und physische Klimarisiken vom Lehrstuhl für Sustainable Finance, Universität Kassel as of September Dec. 17th, 2023: “Approximately 40 percent of the surveyed institutions do not take physical climate risks into account when valuing corporate bonds. In addition, a majority of respondents who already take physical climate risks into account are unsure whether these risks are adequately taken into account. In this regard, Part II reveals that 80% of the surveyed institutional investors believe that physical climate risks are not adequately reflected in the risk premiums of corporate bonds” (abstract).

Voting deficits: Voting matters 2023 by Abhijay Sood at al from Share Action as of Jan. 11th, 2024: “In 2023, only 3% of assessed resolutions passed, just eight out of 257 resolutions. This is down from 21% of assessed resolutions in 2021 … In 2023, the ‘big four’ (BlackRock, Vanguard, Fidelity Investments, and State Street Global Advisors) only supported – on average – one eighth of those put forward, a marked drop since 2021 … Eight asset managers with public net zero targets supported fewer than half of all climate resolutions … Three quarters of all shareholder proposals covered in our study asked only for greater corporate disclosure, including those which some asset managers have deemed overly “prescriptive”. The other quarter of resolutions ask for movement in line with globally agreed climate goals or international human rights standards. … Resolutions at financial services companies on fossil fuel financing received the lowest support by asset managers of any climate-related topic” (p. 8-10). My comment: I focus more on direct dialogue (engagement) than voting, see Shareholder engagement: 21 science based theses and an action plan – (

Divestment myths: Beyond Divestment by David Whyte as of Jan. 16th, 2024 (#11): “The top 20 shareholders in both BP and Shell have increased their total number of shares by three quarters of a billion in BP, and half a billion in Shell since the Paris Agreement was signed in 2015. Indeed, although 47% of BP shareholders and 54% of Shell shareholders have reduced their stake, net share ownership overall has risen significantly in both companies. … more than a quarter of the 20 investors who made the most significant reductions in shareholdings in either BP or Shell increased their overall fossil fuel investment. … only 60 institutional investors have sold all of their shares in the two oil firms. This represents 3% of BP and 4% of Shell shareholders“ (abstract).

Diversification myths: Diversification Is Not A Free Lunch by Dirk G. Baur as of Jan. 3rd, 2024 (#56): “We … demonstrate that diversification generally comes at a cost through lower returns and is thus not a free lunch. While the risk of diversified portfolios is clearly lower than that of less diversified or undiversified portfolios, the return is generally also lower. There is only one exception. If the investor is ignorant and picks stocks randomly, diversification is a free lunch. … if diversification is a free lunch, it would violate the fundamental positive risk – return relationship in finance. Specifically, if risk can be reduced without a cost, risk and return are not positively aligned” (p.15). My comment: Even for randomly picked stocks the marginal gains of diversification are very low (see p. 11) whereas the reductions in sustainability – which are not covered in this paper – can be high, see 30 stocks, if responsible, are all I need – Responsible Investment Research Blog (

Normal anomalies: Anomalies Never Disappeared: The Case of Stubborn Retail Investors by Xi Dong and Cathy Yang as of Dec. 29th, 2023 (#56): “Our examination of 260 anomalies challenges the prevailing notion that market efficiency erodes anomaly-based profits, these anomalies continue to thrive, especially over longer timeframes. We demonstrate that retail investors play a pivotal role in the persistence of these anomalies. Their stubborn trading patterns, especially against anomalies, not only contribute to initial mispricing but also lead to delayed price corrections“ (p. 37).

Trend following theory: Speculating on Higher Order Beliefs by Paul Schmidt-Engelbertz and Kaushik Vasudevan as of Aug.3rd, 2023 (#187): “We study investors’ higher order beliefs, using survey data from the Robert Shiller Investor Confidence surveys. While previous work has documented instances of non-fundamental speculation – investors taking positions in a risky asset in a direction that conflicts with their fundamental views – we find that such speculation is the norm for the U.S. stock market. The majority of investors in the Shiller surveys, who represent an important class of investors, report that other investors have mistaken beliefs, but nevertheless report positive return expectations from speculating in the direction of these mistaken beliefs. In addition, investors report that they believe that stock markets overreact and exhibit momentum and reversal in response to news. … We find that higher order beliefs may substantially amplify stock market fluctuations. When investors exhibit the same fundamental belief biases that they attribute to other investors, patterns such as overreaction, momentum, and reversal can persist in equilibrium, even though everybody knows about them“ (p. 37/38). My comment: I use simple trend following strategies to reduce drawdown-risks for investors who do not like bond investments but not to try to enhance returns

US Real Estate: A First Look at the Historical Performance of the New NAV REITs by Spencer J. Couts and Andrei S. Goncalves as of Jan.12th, 2024 (#31): “…we study the historical investment performance of NAV REITs relative to public bonds, public equities, and public REITs from 2016 to 2023. … First, the smoothness of NAV REIT returns due to lagged price reactions creates an important challenge to the measurement of the alphas of NAV REIT investments relative to public market indices. Moreover, return unsmoothing methods significantly mitigate (but do not fully solve) this issue. Second, traditional performance analysis indicates that NAV REIT investments generated substantial alpha (above 5% per year) relative to public indices over our sample period“ (p. 26).

PE calculation-uncertainties: Unpacking Private Equity Performance by Gregory Brown and William Volckmann as of Dec. 20th., 2023 (#31): “… complicating the analysis are the increasingly common practices of funds using subscription lines of credit (fund-level debt) and recycling capital. Even the variation in the timing of capital deployment across funds has important implications for common performance measures used to evaluate funds such as internal rate of return (IRR) and multiple on invested capital (MOIC). …. values likely observed during fundraising periods for subsequent funds – are strongly affected by subscription lines and deployment pacing. Intermediate MOICs are only weakly affected by subscription lines, but strongly affected by capital deployment pacing. Both IRRs and MOICs are strongly affected by recycle deal accounting methodology“ (abstract). “When a fund utilizes subscription lines, net IRR is very sensitive over the life cycle of the fund and can massively exaggerate performance during the investment/fundraising period. Net MOIC can also be exaggerated early in the investment period …” (p. 17).

Broad biodiversity risk: Living in a world of disappearing nature: physical risk and the implications for financial stability by Simone Boldrini, Andrej Ceglar, Chiara Lelli, Laura Parisi, and Irene Heemskerk from the European Central Bank as of Nov. 14th, 2023 (#23): “Of the 4.2 million euro area NFCs (Sö: Non-financial corporations) that were included in our research, around 3 million are highly dependent on at least one ecosystem service. … approximately 75% of euro area banks’ corporate loans to NFCs (nearly €3.24 trillion) are highly dependent on at least one ecosystem service. … we have enough data and knowledge available to enable timely and nature-friendly decision-making” (p. 38).

Biodiversity risk reduction? How could the financial sector contribute to limiting biodiversity loss? A systematic review by Lisa Junge, Yu-Shan Lin Feuer, and Remmer Sassen as of Feb. 7th, 2023 (#109) “the currently available scientific discourse is also not unanimous about the status of biodiversity in finance. Therefore, this paper aims to synthesise existing publications to gain transparency about the topic, conducting a systematic review. Three main concepts emerge about how the private finance sector can aid in halting biodiversity loss, namely: (1) by increasing awareness of biodiversity, (2) by seizing biodiversity-related business opportunities, and (3) by enlarging biodiversity visibility through reporting. Overall, we assume that the private finance sector upholds a great leverage power in becoming a co-agent of positive biodiversity change”(abstract).

Blackrock-problem? Fossil-washing? The fossil fuel investment of ESG funds by Alain Naef from Banque de France as of Nov. 16th, 2023 (#19): “… I analysed all the large equity Exchange Traded Funds (ETFs) labelled as ESG available at the two largest investors in the world: Blackrock and Vanguard. For Blackrock, out of 82 funds analysed, only 9% did not invest in fossil fuel companies. Blackrock ESG funds include investments in Saudi Aramco, Gazprom or Shell. But they exclude ExxonMobil or BP. This suggests a best-in-class approach by the fund manager, picking only certain fossil fuel companies that they see as generating less harm. But it is unclear what the criteria used are. For Vanguard, funds listed as ESG did not contain fossil fuel investment. Yet this needs to be nuanced as information provided by Vanguard on investments is less transparent and Vanguard offers fewer ESG funds” (abstract). My comment: For my ESG and SDG ETF-selection I use demanding responsibility criteria and more so for my direct equity portfolios, see the newly updated Das-Soehnholz-ESG-und-SDG-Portfoliobuch.pdf (

Listed equity climate deficits: The MSCI Net-Zero Tracker November 2023 – A guide to progress by listed companies toward global climate goals from the MSCI Sustainability Institute as of November 2023: “Listed companies are likely to put 12.4 gigatons (Gt) of GHG emissions into the atmosphere this year, up 11% from 2022. … global emissions are on track reach 60.6 Gt this year, up 0.3% from 2022. … Domestic emissions in eight emerging-market G20 countries examined rose by an average of 1.2% per year over the period, while emissions of listed companies in those markets climbed 3.2% annually. … Just over (22%) of listed companies align with a 1.5°C pathway, as of Aug. 31, 2023 … Listed companies are on a path to warm the planet 2.5°C above preindustrial levels this century … More than one-third (34%) of listed companies have set a climate target that aspires to reach net-zero, up from 23% two years earlier. Nearly one-fifth (19%) of listed companies have published a science-based net-zero target that covers all financially relevant Scope 3 emissions, up from 6% over the same period” (page 6/7).

ESG or cash flow? Does Sustainable Investing Make Stocks Less Sensitive to Information about Cash Flows? by Steffen Hitzemann, An Qin, Stanislav Sokolinski, and Andrea Tamoni as of Oct. 30th, 2023 (#56): “Traditional finance theory asserts that stock prices depend on expected future cash flows. … Using the setting of earnings announcements, we find that sustainable investing diminishes stock price sensitivity to earnings news by 45%-58%. This decline in announcement-day returns is mirrored by a comparable drop in trading volume. This effect persists beyond the immediate announcement period, implying a lasting alteration in price formation rather than a short-lived mispricing“ (abstract).

Similar calls: SLBs: no cal(l)amity by Kamesh Korangi and Ulf Erlandsson as of Nov. 16th, 2023 (#13): A common criticism of sustainability-linked bonds (SLBs) has been around callability, where it is sometimes suggested that bond issuers are pushing this feature into bond structures to wriggle out of sustainability commitments. … Our analysis finds scant quantitative evidence to support this critique. Overall, when comparing SLBs with similar non-SLB issuances, we observe little ‘excess’ callability in SLBs. The key to this result is to control for sectors, ratings and issue age when comparing SLBs with the much larger market of traditional bonds” (p. 1).

100% Equity! Beyond the Status Quo: A Critical Assessment of Lifecycle Investment Advice by Aizhan Anarkulova, Scott Cederburg and Michael S. O’Doherty as of Nov.1st, 2023 (#950): “We challenge two central tenets of lifecycle investing: (i) investors should diversify across stocks and bonds and (ii) the young should hold more stocks than the old. An even mix of 50% domestic stocks and 50% international stocks held throughout one’s lifetime vastly outperforms age-based, stock-bond strategies in building wealth, supporting retirement consumption, preserving capital, and generating bequests. These findings are based on a lifecycle model that features dynamic processes for labor earnings, Social Security benefits, and mortality and captures the salient time-series and cross-sectional properties of long-horizon asset class returns” (abstract).

Lemming investors? The Big Shortfall? Thematic investors lose lion’s share of returns due to poor timing by Kenneth Lamont and Matias Möttölä from Morningstar as of Nov. 15th, 2023 : “While thematic funds‘ average total return was 7.3% annualized over the five-year period through June 30, 2023, investors earned only a 2.4% return when the impact of cash inflows and outflows is considered. … Investors lost more value in focused funds such as those tracking Technology or Physical World broad themes compared with more diversified Broad Thematic peers. Return gaps were far wider in exchange-traded funds than in thematic mutual funds. ETFs tend to offer more concentrated bets and lend themselves to tactical usage. The largest return shortfalls occur across highly targeted funds, which posted eye-catching performance, attracting large net inflows before suffering a change of fortune“ (p. 1). My comment: My approach to thematic investments see e.g. Alternatives: Thematic replace alternative investments (

Risk-loving altruists? Can Altruism Lead to a Willingness to Take Risks? by Oded Shark as of Mov. 7th, 2023 (#7): “I show that an altruistic person who is an active donor (benefactor) is less risk averse than a comparable person who is not altruistic: altruism is a cause of greater willingness to take risks” (abstract). … “The lower risk aversion of an altruistic person … might encourage him to pursue risky ventures which could contribute to economic growth and social welfare” (p. 7).

Unstable coins? Runs and Flights to Safety: Are Stablecoins the New Money Market Funds? by Kenechukwu Anadu et al. from the Federal Reserve Bank of Boston as of Oct. 9th, 2023 (#743): “… flight-to-safety dynamics in money market funds have been extensively documented in the literature—with money flowing from the riskier prime segment of the industry to the safer government segment … flight-to-safety dynamics in stablecoins resemble those in the MMF industry. During periods of stress in crypto markets, safer stablecoins experience net inflows, while riskier ones suffer net outflows. … we estimate that when a stablecoin’s price hits a threshold of 99 cents (that is, a price drop of 100 basis points relative to its $1 peg), investor redemptions accelerate significantly, in a way that is reminiscent of MMFs’ “breaking the buck … Should stablecoins continue to grow and become more interconnected with key financial markets, such as short-term funding markets, they could become a source of financial instability for the broader financial system” (p. 33).

Social and ecological research (responsible derivatives)

Migration policy backlash: The Effect of Foreign Aid on Migration: Global Micro Evidence from World Bank Projects by Andreas Fuchs, Andre Groeger, Tobias Heidland and Lukas Wellner as of Oct. 2023: “Our short-term results indicate that the mere announcement of a World Bank aid project significantly decreases migration preferences. We find similar effects for project disbursements, which also reduce asylum seeker flows to the OECD in the short run. This reduction seems related to enhanced optimism about the economic prospects in aid recipient provinces and improved confidence in national institutions. In the longer run, aid projects increase incomes and alleviate poverty. The negative effect of aid on asylum seeker flows fades out, and regular migration increases. … There is no evidence in our study that targeting the “root causes” of migration through aid on average increases irregular migration or asylum seeker numbers. … In the short run, aid projects reduce migration preferences and asylum seeker flows to the OECD from Latin America, MENA, and non-fragile Sub-Saharan African countries. However, we do not find a significant effect in fragile countries of Sub-Saharan Africa, which are an important source of irregular migration to Europe. For policymakers, a key takeaway from our study is that aid projects do not keep people from migrating from the 37 most hostile environments, but they can be effective in more stable environments” (p. 37/38).

Rating beats label: Talk vs. Walk: Lessons from Silent Sustainable Investing of Mutual Funds by Dimitrios Gounopoulos, Haoran Wu, and Binru Zhao as of Oct. 26th, 2023 (#81): “… in the Morningstar fund sustainability rating landscape, most funds with top ratings do not self-label as ESG funds (“silent” sustainable investing). … We find that investors tend to overemphasize ESG labels and often overlook sustainability rating signals in the market. More importantly, we show that “silent” funds with high sustainability ratings have comparable return performance to ESG funds and that high sustainability ratings have a stronger influence on mitigating fund risks than the ESG label” (p. 33/34). My comment: In general, I agree. But the type of ESG rating used is also very important. Watch out for my next opinion blogpost on Apple, Amazon, Alphabet etc. and their ESG-ratings

Biodiversity confusion: Critical review of methods and models for biodiversity impact assessment and their applicability in the LCA context by Mattia Damiani, Taija Sinkko, Carla Caldeira, Davide Tosches, Marine Robuchon, and Serenella Sala as of Nov. 17th, 2022 (#139): “… The five main direct drivers of biodiversity loss are climate change, pollution, land and water use, overexploitation of resources and the spread of invasive species. …  this article aims to critically analyse all methods for biodiversity impact assessment … 54 methods were reviewed and 18 were selected for a detailed analysis … There is currently no method that takes into account all five main drivers of biodiversity loss” (abstract).

Explain to change: Voting Rationales by Roni Michaely, Silvina Rubio, and Irene Yi as of Aug. 16th, 2023 (#279): “…studying voting rationales of institutional investors from across the world, for votes cast in US companies’ annual shareholder meetings between July 2013 and June 2021. … institutional investors vote against directors mainly because of (lack of) independence and board diversity. We also find evidence of some well-known reasons for opposing directors, such as tenure, busyness, or firm governance. Institutional investors are increasingly voting against directors due to concerns over environmental and social issues. Our results indicate that voting rationales are unlikely to capture proxy advisors’ rationales, but rather, the independent assessment of institutional investors. … We find that companies that receive a higher proportion of voting rationales related to board diversity (or alternatively, excessive tenure or busy directors) increase the fraction of females on board in the following year (reduce average tenure or director busyness), and the results are driven by companies that receive high shareholder dissent. … our results suggest that disclosure of voting rationales is an effective, low-cost strategy that institutional investors can use to improve corporate governance in their portfolio companies“ (p. 31/32).

Impact impact? Evaluating the Impact of Portfolio Mandates by Jack Favilukis, Lorenzo Garlappi, and  Raman Uppal as of Oct. 2nd, 2023 (#56): “… we examine the impact of portfolio (Sö: e.g. ESG or impact investing) mandates on the allocation of physical capital in a general-equilibrium economy with production and heterogenous investors. … we find that the effect of portfolio mandates on the allocation of physical capital across sectors can be substantial. In contrast, the impact on the equilibrium cost of capital and Sharpe ratio of firms in the two sectors remains negligible, consistent with existing evidence. Thus, a key takeaway of our analysis is that judging the effectiveness of portfolio mandates by studying their effect on the cost of capital of affected firms can be misleading: small differences in the cost of capital across sectors can be associated with significant differences in the allocation of physical capital across these sectors” (p. 31/32). My comment: With my ESG and SDG investing mandates I want to invest as responsibly as possible and hope to achieve similar performances as less responsible investments. With this approach, there is no need to try to prove lower cost of capital for responsible companies.

Responsible derivatives? Climate Risk and Financial Markets: The Case of Green Derivatives by Paolo Saguato as of Oct. 30th, 2023 (#37): “The post-2008 derivatives markets are more transparent and more collateralized than before. However, this regulatory framework might impose excessive regulatory and compliance costs to derivatives market which would undermine market incentives and hamper financial innovation in the green derivatives. … Right now, bespoke OTC sustainable derivatives are the predominant structures in the market, but as soon as green assets and sustainability benchmark standardization will become the norm, then exchange-traded green derivatives might start to develop more strongly, providing a valuable and reliable support to a green transition” (p. 23).

Responsible derivatives? Structured retail products: risk-sharing or risk-creation? by Otavio Bitu, Bruno Giovannetti, and Bernardo Guimaraes as of October 31, 2023 (#151): “Financial institutions have been issuing more complex structured retail products (SRPs) over time. Is risk-sharing the force behind this financial innovation? Is this innovation welfare-increasing? We propose a simple test for that. If a given type of SRP is not based on risk-sharing and pours new unbacked risk into the financial system, we should observe an unusual negative relation between risk and expected return offered to buyers across products of that type. We test this hypothesis using a sample of 1,847 SRPs and find that a relevant type of SRP (Autocallables) creates new unbacked risk” (abstract).

Irrational finance professional? Mental Models of the Stock Market by Peter Andre, Philipp Schirmer, and Johannes Wohlfart as of Oct. 31st, 2023 (#74): “Financial markets are governed by return expectations, which agents must form in light of their deeper understanding of these markets. Understanding agents’ mental models is thus critical to understanding how return expectations are formed. … We document a widespread tendency among households from the general population, retail investors, and financial professionals to draw inferences from stale news regarding future company earnings to a company’s prospective stock return, which is absent among academic experts. This striking difference in their return forecasts results from differences in agents’ understanding of financial markets. Experts’ reasoning aligns with standard asset pricing logic and a belief in efficient markets. By contrast, households and financial professionals appear to employ a naive model that directly associates higher future earnings with higher future returns, neglecting the offsetting effect of endogenous price adjustments. This non-equilibrium reasoning stems from a lack of familiarity with the concept of equilibrium rather than inattention to trading or price responses. … Our findings – that mental models differ across economic agents and that they drastically differ from standard economic theories among important groups of households and financial professionals who advise and trade for these households – are likely to have significant implications. For example, our findings can provide a new perspective on previously documented anomalies in return expectations and trading decisions” (p. 30/31).

M&A not IPO: IPOs on the decline: The role of globalization by M. Vahid Irani, Gerard Pinto, and Donghang Zhang as of Oct. 2nd, 2023 (#37): “Using the average percentage of foreign sales as a proxy for the level of globalization of the U.S. economy or a particular industry, we find that the decline in U.S. initial public offerings (IPOs), particularly small-firm IPOs, is significantly positively associated with the level of globalization at both the macroeconomy and the industry levels. We also find that increased globalization of an industry makes a U.S. private firm in the industry more likely to choose M&A sellouts over IPOs as an exit strategy”“ (abstract).

Unattractive Alternatives: Endowments in the Casino: Even the Whales Lose at the Alts Table by Richard M. Ennis as of Oct. 27th, 2023 (#516): “For more than two decades, so-called alternatives—hedge funds, private-market real estate, venture capital, leveraged buyouts, private energy, infrastructure, and private debt—have been the principal focus of institutional investors. Such investments now constitute an average of 60% of the assets of large endowments and 30% of public pension funds. … … endowments—across the board—have underperformed passive investment alternatives by economically wide margins since the GFC (Sö: Global Financial Crisis) … We observe that large endowments have recorded greater returns than smaller ones because they take greater risk (have a greater equity exposure), not as a result of their alt investing. In fact, their greater returns have occurred in spite of their heavier weighting of alt investments. Alt-investing has not been a source of diversification of stock market risk. … I estimate that institutional investors pay approximately 10 times as much for their alts as they do for traditional stock-bond strategies… despite exhibiting some skill with alts, large endowments would have been better off leaving them alone altogether” (p. 8/9). My comment: See Alternatives: Thematic replace alternative investments (

Too late? Earth beyond six of nine planetary boundaries by Katherine Richardson and many more as of Sept. 13th, 2023: “This planetary boundaries framework update finds that six of the nine boundaries are transgressed, suggesting that Earth is now well outside of the safe operating space for humanity. Ocean acidification is close to being breached, while aerosol loading regionally exceeds the boundary. Stratospheric ozone levels have slightly recovered. The transgression level has increased for all boundaries earlier identified as overstepped. As primary production drives Earth system biosphere functions, human appropriation of net primary production is proposed as a control variable for functional biosphere integrity. This boundary is also transgressed.

Social measures: How useful are convenient measures of pro-environmental behavior? Evidence from a field study on green self-reports and observed green behavior by Ann-Kathrin Blankenberg, Martin Binder, and Israel Waichmann as of Aug. 20th, 2023 (#12): “We conduct a field study with n = 599 participants recruited in the town hall of a German medium-sized town to compare self-reports of pro-environmental behavior of our participants with observed behavior (green product choice and donation to real charities). Our results indicate that self-reports are only weakly correlated to incentivized behavior in our sample of an adult population (r = .09∗ ), partly because pro-environmental behavior measures can conflate prosocial and pro-environmental preferences. … Our results … cast some doubt on the validity of commonly used convenient measures of pro-environmental behavior“ (abstract).

Expensive subsidies: Converting the Converted: Subsidies and Solar Adoption by Linde Kattenberg, Erdal Aydin, Dirk Brounen, and Nils Kok as of July 25th, 2023 (#18): „… there is limited empirical evidence on the effectiveness of subsidies that are used to promote the adoption of such (Sö: renewable energy) technologies. This paper exploits a natural experimental setting, in which a solar PV subsidy is assigned randomly within a group of households applying for the subsidy. Combining data gathered from 100,000 aerial images with detailed information on 15,000 households … The results show that, within the group of households that applied for the subsidy, the provision of subsidy leads to a 14.4 percent increase in the probability of adopting solar PV, a 9.6 percent larger installation, and a 1-year faster adoption. However, examining the subsequent electricity consumption of the applicants, we report that the subsidy provision leads to a decrease in household electricity consumption of just 8.1 percent, as compared to the rejected applicant group, implying a cost of carbon of more than €2,202 per ton of CO2”.

Regulatory SME effects: The EU Sustainability Taxonomy: Will it Affect Small and Medium-sized Enterprises? by Ibrahim E. Sancak as of Sept. 6th, 2023 (#52): “The EU Sustainability Taxonomy (EUST) is a new challenge for companies, particularly SMEs and financial market participants; however, it potentially conveys its economic value; hence, reliable taxonomy reporting and strong sustainability indicators can yield enormously. … We conclude that the EU’s sustainable finance reforms have potential domino effects. Backed by the European Green Deal, sustainable finance reforms, and in particular, the EUST, will not be limited to large companies or EU companies; they will affect all economic actors having business and finance connections in the EU“ (p. 14).

ESG rating credits: Determinants of corporate credit ratings: Does ESG matter? by Lachlan Michalski and Rand Kwong Yew Low as of Aug. 19th, 2023 (#25): “We show that environmental and social responsibility variables are important determinants for the credit ratings, specifically measures of environmental innovation, resource use, emissions, corporate social responsibility, and workforce determinants. The influence of ESG variables become more pronounced following the financial crisis of 2007-2009, and are important across both investment-grade and speculative-grade classes” (abstract).

Climate risk management: Climate and Environmental risks and opportunities in the banking industry: the role of risk management by Doriana Cucinelli, Laura Nieri, and Stefano Piserà as of Aug. 18th, 2023 (#22): “We base our analysis on a sample of 112 European listed banks observed from 2005 to 2021. Our results … provide evidence that banks with a stronger and more sophisticated risk management are more likely to implement a better climate change risk strategy. … Our findings underline that bank providing their employees and managers with specific training programs on environmental topics, or availing of the presence of a CSR committee, or adopting environmental-linked remuneration scheme, stand out for a greater engagement towards C&E risks and opportunities and a sounder C&E strategy” (p. 16).

ESG dissected: It’s All in the Detail: Individual ESG Factors and Firm Value by Ramya Rajajagadeesan Aroul, Riette Carstens and Julia Freybote as of Aug. 25th, 2023 (#29): “We disaggregate ESG into its individual factors (E, S and G) and investigate their impact on firm value using publicly listed equity real estate investment trusts (REITs) as a laboratory over the period of 2009 to 2021. … We find that the environmental factor (E) and governance factor (G) positively predict firm value while the social factor (S) negatively predicts it. … Further analysis into antecedents of firm value suggests that our results are driven by 1) E reducing cost of debt and increasing financial flexibility, operating efficiency, and performance, 2) S leading to a higher cost of debt as well as lower financial flexibility and operating performance, and 3) G increasing operating efficiency. … We also find evidence for time-variations in the relationships of E, S and G with firm value and its determinants” (abstract). My comment: This is not really new as one can see in my publication from 2014: 140227 ESG_Paper_V3 1 (

Greenbrown valuations: The US equity valuation premium, globalization, and climate change risks by Craig Doidge, G. Andrew Karolyi, and René M. Stulz as of Sept. 15th, 2023 (#439): “It is well-known that before the GFC (Sö: Global Financial Crisis of 2008), on average, US firms were valued more highly than non-US firms. We call this valuation difference the US premium. We show that, for firms from DMs (Sö: Developed Markets), the US premium is larger after the crisis than before. By contrast, the US premium for firms from EMs (Sö: Emerging Markets) falls. In percentage terms, the US premium for DMs increases by 27% while the US premium for EMs falls by 24%. … the differing evolution of the US premium for DM firms and for EM firms is concentrated among old economy firms – older firms in industries that have a high ratio of tangible assets to total assets. … We find that the valuations of firms in brown industries in non-US DMs fell significantly relative to comparable firm valuations in the US and this decline among brown industries in EMs did not take place. Though this mechanism does not explain the increase in the US premium for firms in DMs fully, it explains much of that increase. It follows from this that differences across countries in the importance given to sustainability and ESG considerations can decrease the extent to which financial markets across the world are integrated“ (p. 28).

Sin ESG: Does ESG impact stock returns for controversial companies? by Sonal and William Stearns as of Sept. 2nd, 2023 (#35): “We find that the market perception of ESG investments of controversial firms have changed over time. For the 2010-2015 period, ESG investments made by sinful firms are rewarded positively by increasing stock prices. However, for the sample period post 2015, increases in ESG no longer result in positive stock returns. We further find the maximum change for the oil and gas industry“ (p. 11/12).

Portfolio ESG effects: Quantifying the Impacts of Climate Shocks in Commercial Real Estate Market by Rogier Holtermans, Dongxiao Niu, and Siqi Zheng as of Sept. 7th, 2023 (#251): “We focus on Hurricanes Harvey and Sandy to quantify the price impacts of climate shocks on commercial buildings in the U.S. We find clear evidence of a decline in transaction prices in hurricane-damaged areas after the hurricane made landfall, compared to unaffected areas. We also observe that …. Assets in locations outside the FEMA floodplain (with less prior perception about climate risk) have experienced larger price discounts after the hurricanes. … Moreover, the price discount is larger when the particular buyer has more climate awareness and has a more geographically diverse portfolio, so it is easier for her to factor in this risk in the portfolio construction” (abstract).

ESG investors or traders? Do ESG Preferences Survive in the Trading Room? An Experimental Study by Alexander Bassen, Rajna Gibson Brandon, Andreas G.F. Hoepner, Johannes Klausmann, and Ioannis Oikonomou as of Sept. 19th, 2023 (#12): “This study experimentally tests in a competitive trading room whether Socially Responsible Investors (SRIs) and students are consistent with their stated ESG preferences. … The results suggest that all participants who view ESG issues as important (ESG perception) trade more aggressively irrespective of whether the news are related to ESG matters or not. … More importantly, SRIs trade on average much less aggressively than students irrespective of their ESG perceptions and behaviors” (abstract). … “Investors mostly consider macroeconomic and id[1]iosyncratic financial news in their investment decisions. Updates on the ESG performance of a firm are perceived as less likely to move prices by the participants. In addition to that, we observe a stronger reaction to positive news compared to negative news” (p. 26).

Supplier ESG research (also see Supplier engagement – Opinion post #211)

Supplier ESG shocks: ESG Shocks in Global Supply Chains by Emilio Bisetti, Guoman She, and Alminas Zaldokas as of Sept. 6th, 2023 (#38): “We show that U.S. firms cut imports by 29.9% and are 4.3% more likely to terminate a trade relationship when their international suppliers experience environmental and social (E&S) incidents. These trade cuts are larger for publicly listed U.S. importers facing high E&S investor pressure and lead to cross-country supplier reallocation …. Larger trade cuts around the scandal result in higher supplier E&S scores in subsequent years, and in the eventual resumption of trade” (abstract).

Sustainable supplier reduction: A Supply Chain Sourcing Model at the Interface of Operations and Sustainability by Gang Li and Yu A. Xia as of Aug. 25th, 2023 (#204): “This research investigates … how to integrate sustainability with sourcing planning decisions and how to address the challenges associated with the integration, such as the balance between operational factors and sustainability factors and the quantitative evaluation of sustainability performance. … Our model suggests that while increasing the number of suppliers may cause additional sustainability risk in supply chain management, decreasing the supply base will decrease the production capacity and increase the risk of delivery delay. Therefore, a firm should carefully set up its global sourcing network with only a limited number of selected suppliers. This finding is particularly true when the focus of sourcing planning gradually moves away from decisions based solely on cost to those seeking excellence in both supply chain sustainability and cost performance“ (p. 32).

Empowering stakeholders: Stakeholder Governance as Governance by Stakeholders by Brett McDonnell as of August 31st, 2023 (#64): “… American stakeholder engagement is limited to soliciting (and on occasion responding to) the opinions of employees, customers, suppliers, and others. True stakeholder governance would involve these groups in actively making corporate decisions. I have suggested various ways we could do this. The focus should be on employees, who could be empowered via board representation, works councils, and unions. Other stakeholders could be less fully empowered through councils, advisory at first but potentially given power to nominate or even elect directors” (p. 19).

Impact investment research (supplier ESG)

Anti-climate concert: Rethinking Acting in Concert: Activist ESG Stewardship is Shareholder Democracy by Dan W. Puchniak and Umakanth Varottil as of Sept. 13th, 2023 (#187): “… the legal barriers posed by acting in concert rules in virtually all jurisdictions prevent institutional investors from engaging in collective shareholder activism with the aim or threat of replacing the board (i.e., “activist stewardship”). Perversely, the current acting in concert rules effectively prevent institutional investors from replacing boards that resist (or even deny) climate change solutions – even if (or, ironically, precisely because) they collectively have enough shareholder voting rights to democratically replace the boards of recalcitrant brown companies. This heretofore hidden problem in corporate and securities law effectively prevents trillions of dollars of shareholder voting rights that institutional investors legally control from being democratically exercised to change companies who refuse to properly acknowledge the threat of climate change” … (abstract).

AI investment risks: Artificial Intelligence (AI) and Future Retail Investment by Imtiaz Sifat as of Sept. 12th, 2023 (#20): “I have analyzed AI’s integration in retail investment. … The benefits spring from access to sophisticated strategies once exclusive to institutional investors. The downside is that the opaque models which facilitate such strategies may aggravate risks and information asymmetry for retail investors. To stop this gap from widening, proper governance is essential. Similarly, the ability to ingest copious alternative data and instantaneous portfolio optimization incurs a tradeoff—too much dependence on historical data invokes modelling biases and data quality cum privacy concerns. It is also likely that AI-dominated markets of the future will be more volatile, and new forms of speculation would emerge as trading platforms incentivize speculation and gamification. The combined forces of these concurrent challenges put a heavy stress on orthodox finance theories …“ (p. 16/17).

Venture careers: Failing Just Fine: Assessing Careers of Venture Capital-backed Entrepreneurs via a Non-Wage Measure by Natee Amornsiripanitch, Paul A. Gompers, George Hu, Will Levinson, and Vladimir Mukharlyamov as of Aug. 30th, 2023 (#131): “Would-be founders experience accelerated career trajectories prior to founding, significantly outperforming graduates from same-tier colleges with similar first jobs. After exiting their start-ups, they obtain jobs about three years more senior than their peers who hold (i) same-tier college degrees, (ii) similar first jobs, and (iii) similar jobs immediately prior to founding their company. Even failed founders find jobs with higher seniority than those attained by their non-founder peers“ (abstract).

GHG math: 10x new research on supply chains, oil and gas companies, EU taxonomy, green employees, green technologies, brown dividends, shareholder wealth and stock trading by Henrik Bessembinder, Andreas Hoepner, Christian Klein, Frank Schiemann and many more  (#: SSRN downloads on July 13th, 2023)

Ecological and social research: GHG math

Complex supplies: How Far Goods Travel: Global Transport and Supply Chains from 1965-2020 by Sharat Ganapati and Woan Foong Wong as of May 9th, 2023 (#94): “Transportation usage per unit of real output has more than doubled as costs decreased by a third. Participation of emerging economies in world trade and longer-distance trade between countries contribute to this usage increase, thereby encouraging longer supply chains. We discuss technological advances over this period, and their interactions with endogenous responses from transportation costs and supply chain linkages. Supply chains involving more countries and longer distances are reflective of reliable and efficient transportation, but are also more exposed to disruptions, highlighting the importance of considering the interconnectedness of transportation and supply chains in policymaking and future work” (abstract).

GHG math problems: Abominable greenhouse gas bookkeeping casts serious doubts on climate intentions of oil and gas companies by Sergio Garcia-Vega, Andreas G. F. Hoepner, Joeri Rogelj and Frank Schiemann as of May 23rd, 2023 (#136): “In our analysis of the Scope 1 emissions reported by companies from the Oil & Gas industry and their respective breakdowns, we found a considerably large amount of misreporting. First, on average, we find that 38.9% of the companies do not add up to the sum of Scope 1 emissions reported. …. in 15.5% of the cases, the sum of the breakdowns exceeds the total Scope 1 emissions reported by the company. … Scope 1 emissions only constitute a small, yet very easiest-to-report fraction of the GHG emissions O&G companies …“ (p. 10/11).

Greenwashing risk: Emissions gaming? A gap in the GHG Protocol may be facilitating gaming in accounting of GHG emissions by David Aikman, Yao Dong, Evangelos Drellias, Swarali Havaldar, Marc Lepere, and Matthias Nilsson as of June 2023: “The framework for calculating firms’ greenhouse gas emissions via the GHG Protocol is highly complex. It involves the collection and management of large datasets on companies’ activities, and both scientific and estimation uncertainty in translating such activities into emissions estimates. Moreover, there are substantial degrees of freedom created by the existence of multiple calculation methods and emission factor databases, which deliver markedly different emissions estimates for the same underlying activity data inputs. … If gaming opportunities are fully exploited, actual emissions for some firms could be several times larger than those currently reported“ (abstract).

German taxonomy gap: Let’s talk numbers: EU Taxonomy reporting by German companies by Jannis Luca Arnold, Thomas Cauthorn, Julia Eckert, Christian Klein and Sebastian Rink as of June 28th, 2023: “On average, 26 percent EU Taxonomy-eligible turnover is reported. … the Consumer Discretionary, Industrial, Real Estate, and Utility industries have substantially higher EU Taxonomy-eligible turnover, CapEx and OpEx. … Real Estate has the highest average EU Taxonomy-eligible turnover at 93 percent. In contrast, Health Care and Consumer Staples have zero percent EU Taxonomy-eligible turnover. The Utility industry has an average EU Taxonomy-eligible turnover of 26 percent. However, Utilities have the highest EU Taxonomy-aligned turnover (15 percent), CapEx (68 percent) and OpEx (34 percent). On average, three percent EU Taxonomy-aligned turnover (of eligible turnover) is reported“ (p. 42).

Green employees: Green Behavior: Factors Influencing Behavioral Intention and Actual Environmental Behavior of Employees in the Financial Service Sector by Joachim P. Hasebrook, Leonie Michalak, Anna Wessels, Sabine Koenig, Stefan Spierling and Stefan Kirmsse  as of August 30th, 2022: “A smartphone friendly online survey concerning the intention to improve and show ‘green behavior’ was sent to 1200 professionals working in 17 locations in 13 European countries, 470 of which responded to the survey (39%). From these participants, 20% are convinced of the need to act in a “green” manner, and only 5% are hardly accessible. Monetary benefits combined with social motives contribute to sustainable living, whereas financial benefits alone actually hinder it“ (abstract).

11 green key technologies: Delivering transformative impact from US green bank financing by McKinsey as of April 20th, 2023: “To reach net zero by 2050, the United States could need an estimated $27 trillion in climate investment. … This report focuses specifically on the estimated need for and impact of investment in 11 key technologies across three themes—household and community decarbonization, business decarbonization, and energy system transformation. Aiding these particular investments could advance the GHGRF’s (Sö: Greenhouse Gas Reduction Fund) dual goals of reducing emissions and benefiting disadvantaged communities while also fulfilling its mission to provide “additionality” through investments that would not have occurred without its funding” (p. 4).

Brown dividends: “Brown” Risk or “Green” Opportunity? The dynamic pricing of climate transition risk on global financial markets by Philip Fliegel as of July 13th, 2023 (#8): “I utilize the TRBC business classification to categorize companies in three climate sensitive sectors into high/low-risk portfolios based on the climate transition risk exposure of their technologies. … My results show that green stocks produce a highly significant double-digit annual alpha, especially in the 7 years following the Paris Agreement. This is well above all previous estimates and might be explained by my proposed methodology which can identify brown and green “pure-plays” in the most climate sensitive economic sectors. … The return expectation today is very different from 2013 … My dividend yield findings indicate that the expect payouts for brown portfolios today is indeed substantially higher compared to green portfolios“ (p. 23).

Few big winners: Shareholder Wealth Enhancement, 1926 to 2022 by Hendrik Bessembinder as of June 18th, 2023 (#636):  “Investments in publicly-listed U.S. stocks enhanced shareholder wealth by more than $55.1 trillion in aggregate during the 1926 to 2022 period, even while investments in the majority (58.6%) of the 28,114 individual stocks led to reduced rather than increased shareholder wealth. The degree to which wealth enhancement is concentrated in relatively few stocks has increased over time: for example, the number of high-performing firms that explain half of the net wealth creation since 1926 decreased from ninety as of 2016 to eighty-three as of 2019 and to seventy-two as of 2022. I identify the firms with both the largest enhancements and largest reductions in shareholder wealth since 1926 and during more recent intervals” (abstract).

Too frequent info: Alert for Alerts: How Investment Price Tracking Alerts Affect Retail Investors by Che-Wei Liu, Yanzhen Chen, and Ming-Hui Wen as of June 5th, 2023 (#97): “… we reveal that price tracking alerts, which provide convenient access to price data and cost-effective investment monitoring, lead to increased trading activity, suboptimal market timing, and diminished investment returns. Furthermore, our findings suggest that the availability of such investment management tools intensifies overconfidence bias and magnifies the disadvantage of inadequate financial literacy“ (p. 35).

Offset-Accounting: Accounting for carbon offsets – Establishing the foundation for carbon-trading markets by Robert S. Kaplan, Karthik Ramanna, and Marc Roston as of Feb. 28th, 2023 (#198): “Tackling climate change requires not only reducing GHG emissions but also removing GHG from the atmosphere. … But existing carbon-offset markets have been criticized for poor measurement practices and inadequate controls, resulting in transaction of products that do not materially sequester carbon. … we apply basic financial-accounting principles to develop an accurate and auditable framework for offset accounting. … rigorous accounting for emissions and offsets can improve and expand markets for impactful decarbonization” (abstract).

Green cover investments? Do Investors Compensate for Unsustainable Consumption Using Sustainable Assets? by Emily Kormanyos as of Feb. 28th, 2023 (#61): “… high-footprint consumers seem to understand the environmental impacts of their consumption patterns, and aim to offset them by investing specifically in securities which have extremely low-emission profiles. I present additional evidence that investors use only these specific securities to offset their carbon-based emissions, whereas portfolios with high general ESG ratings do not exhibit such a relation to unsustainable consumption. … I show that Catholicism, historically tied to financial offsetting practices through the 15th and 16th-century letters of indulgence, is significantly and positively related to the sustainability profile of retail investor portfolios … Finally, I conduct a survey with 3,646 clients of the same bank that provided the administrative data analyzed in this paper, finding that the majority of investors underestimate their own carbon footprints from consumption. This underestimation increases systematically in the size of the survey participants’ real footprints …”  (p. 45/56).

Beyond Scope 3: Modelling Resilience to a Lower-Emissions Future by Debarshi Basu, Gerald T Garvey, Shuangzi Guo, and Ryan Zamani from Blackrock as of Dec. 6th, 2022 (#31): “We … compute the full supply-chain adjusted carbon footprint of 57 industries in 54 countries … We find a significant full-scope carbon footprint of industries such as Finance and Health Care despite their small direct emissions. At the other end, high-emitting industries such as Air Transport, Retailing, and Rubber support a wide range of otherwise low-carbon downstream activities and appear resilient to a low carbon transition. To test the model with historical data, we use high historical energy prices to proxy more stringent carbon regulation. Industries that our model classifies as resilient perform equally across high and low energy prices. By contrast, industries that are currently classified as green based on naïve emissions significantly underperform in times of high energy costs” (abstract).

Smarter women (1): Income Misperception and Populism by Thilo N. H. Albers, Felix Kersting, and Fabian Kosse as of November 16th, 2022 (#13): “Based on a representative sample of German households, we find that individuals with pessimistic beliefs about their own income position have more right-wing populist attitudes. …. Men are more likely to translate dissatisfaction resulting from income misperception into populist attitudes than women. Our findings show that misperception strongly matters for populist attitudes, also in comparison to the objective income position. … policymakers … could improve citizens’ information about the households’ respective relative income position. … unintended consequences could occur. For example, the radical Norwegian approach towards transparency—one could query the income of every citizen online—decreased happiness among the poor (Perez-Truglia 2020)“ (p. 15).

Old anti-immigrants? No Country for Young People? The Rise of Anti-Immigration Politics in Ageing Societies by Valerio Dotti as of  Oct. 7th, 2022 (#3): “… population ageing and rising income inequality increase the political pressure to restrict the inflow of immigrant workers and inflate the size of government. … We show that ageing and rising inequality can help explain the success of anti-immigration politicians and parties in recent years. … the tightening of immigration policy induced by population ageing and rising inequality is generally harmful, though the harm is most severe for young people and future generations” (p. 44).
