Abstract
Do economic incentives govern information diffusion in markets? Using international banks’ advisory activities in corporate takeovers as their source of private information, we show in supervisory data that banks with closer ties to the target, but not the acquirer, advisor trade profitably in the target’s stock prior to the deal announcement. This trading behavior is associated with a higher premium paid by the acquirer without compromising the deal success. As the incentives of informed traders are aligned only with those of the target shareholders, which are represented by the target advisor, our evidence suggests strategic information transmission among these banks.

When Protecting Children Hits the Bottom Line: Evidence From SDG2000 Firms
Wiebke Szymczak
Scandinavian Journal of Management,
Vol. 42 (2),
2026
Abstract
Intergenerational justice is a core principle of sustainability, yet empirical metrics on the impact of business on future generations remain scarce. Moreover, evidence suggests that different ESG scores capture distinct dimensions of corporate responsibility, highlighting the need for more targeted assessments. This study examines the relationship between corporate engagement with children’s rights and financial performance using a dataset of 1672 firm-year observations, combining a novel children’s rights benchmark with Refinitiv’s financial and sustainability metrics. Results indicate a negative association between marketplace ratings, assessing firms’ child welfare considerations in marketing, and accounting-based profitability, even when controlling for ESG subscores. However, no similar relationship emerges in stock market performance. These findings highlight potential tensions between corporate responsibility and short-term financial outcomes, emphasizing the role of regulatory frameworks and stakeholder engagement in balancing financial and social objectives.

Market Feedback Effect on CEO Pay: Evidence from Peers’ Say-on-Pay Voting Failures
Agnes Cheng, Iftekhar Hasan, Feng Tang, Jing Xie
Journal of Financial and Quantitative Analysis,
Vol. 61 (3),
2026
Abstract
This article shows that when a compensation peer firm experiences a significant failure in its say-on-pay (SOP) voting, the focal firm’s stock price is adversely affected, resulting in reduced CEO pay in the subsequent period. This pay-reduction effect is amplified when the board is more powerful, when proxy advisors express concerns about CEO pay, and when the compensation consultant lacks quality. Directors who react to the price drop and cut the CEO’s pay receive higher votes in future director elections, implying a market feedback effect for directors of the focal firm triggered by their peers’ SOP voting failure.

Common Ownership, Tacit Know-How, and the Market for Technology
Dennis Hutschenreiter
IWH Discussion Papers,
No. 3,
2026
Abstract
Firms increasingly rely on markets for technology to acquire innovations developed outside their boundaries, yet acquiring intellectual property rights alone often does not guarantee successful implementation. Many technologies depend on tacit know-how that must be supplied by the provider after the transaction is completed. This paper examines whether common ownership between a technology provider and a potential adopter mitigates this implementation problem. I develop a model in which overlapping institutional investors cause the provider to partially internalize the adopter’s gains from successful implementation, strengthening incentives to transfer tacit know-how. This mechanism operates only when know-how is unverifiable – absent this friction, common ownership leaves matching and outcomes unchanged. Under moral hazard, the model predicts that common ownership increases the likelihood of technology transfer to a given adopter, that this effect is stronger when tacit know-how is more important, and that common ownership improves post-transfer outcomes conditional on adoption. I test these predictions using U.S. patent reassignments between publicly traded firms. Using within-deal variation across competing potential adopters and plausibly exogenous variation from passive index-fund holdings, I show that common ownership increases the likelihood that a firm acquires a technology, particularly when the transferred bundle is more tacit. Common ownership predicts stronger subsequent innovation and higher future firm value, especially when ownership overlap is concentrated among investors with stronger incentives to monitor the provider. These findings show how ownership structure shapes interfirm technology transfer by affecting not only who acquires a technology, but also how much value is created.

Social Capital and Retail Investor Behavior: Evidence From the Corporate Social Irresponsibility Shocks in Taiwan
Dien Giau Bui, Ting-Hsuan Chen, Iftekhar Hasan, Chih-Yung Lin
Journal of International Financial Markets, Institutions and Money,
Vol. 108 (April),
2026
Abstract
In this paper, we use granular trading data from Taiwan between 2012 and 2016 to examine how local social capital influences retail investor behavior during corporate social irresponsibility (CSIR) events. Therefore, we are responding to longstanding calls in the international finance literature to explore investor behavior in non-US markets with distinct institutional and cultural characteristics. We find that investors residing in cities with higher social capital are less likely to purchase underpriced stocks following the announcements of negative events despite the potential for positive abnormal returns. This norm-driven restraint reflects a form of socially responsible investing motivated by community-based values rather than economic rationality. By documenting this behavior in an East Asian market, we extend the external validity of social norm theories developed in Western settings and contribute to a more nuanced understanding of how localized social preferences can influence asset pricing and capital allocation in a global context.

Do Institutional Investors Exploit Expectation Errors in Value/Glamour Stocks?
Iftekhar Hasan, Jianfu Shen, Chi Cheong Allen Ng
China Accounting and Finance Review,
Vol. 28 (1),
2026
Abstract
This study examines the institutional demand for mispriced stocks with incongruent expectations implied by the book-to-market (BM) ratio and financial strength. Institutional trading (or institutional demand) is calculated by both changes in institutional ownership (percentage of shares held) and the number of institutional investors from the previous to the current quarter. Market mispricing and expectation errors in value/glamour stocks can be identified by analysing firms’ recent financial strength (measured by FSCORE). Firms are sorted into value stocks (top 30%), middle stocks (between 30% and 70%) and glamour stocks (bottom 30%) by distribution of BM ratios at the end of the previous fiscal year. Firms in the sample are then double sorted by FSCORE and BM: in each BM portfolio, firms are further classified into high-, mid- and low-FSCORE groups. Consistent with the argument of expectation errors in value/glamour stocks (Piotroski and So, 2012), institutional investors buy value stocks with strong fundamentals (underpriced) and sell glamour stocks with weak fundamentals (overpriced). Independent institutions are more likely to take advantage of the mispricing in value/glamour firms than passive institutions. Institutional trading on expectation errors could reduce the abnormal returns to mispriced stocks. Institutional trading patterns on mispriced value/glamour stocks are also documented in global markets. Our research provides new evidence that the institutional investors do exploit the BM anomalies if the mispricing can be identified by both the BM and the recent financial strength. Our study differs from Caglayan, Celiker and Sonaer (2018) as we emphasise that financial institutions, in addition to relying on only the BM values, process information from financial statements to infer firms’ financial strength. This study is also the first to document that institutional demand on mispricing could attenuate the BM anomaly.

The Price of Beauty: Biodiversity Effects on Residential Housing Markets
Michael Koetter, Birte Winter, Fabian Woebbeking
IWH Discussion Papers,
No. 21,
2025
Abstract
We study how and why local biodiversity affects residential property values. Leveraging remotely sensed greenness indicators and a novel dataset of granular property listings, we examine how changes in vegetation load on real estate prices. Hikes in greenness are associated with higher listing prices, fewer properties listed, and reduced liquidity in housing markets. These results suggest that price hikes in housing markets are driven by supply-side constraints instead of a “greenium” that buyers might be willing to pay due to innate preferences. Exogenous zoning shocks to foster biodiversity corroborate the presence of supply side constraints as price drivers in residential housing markets. Our findings emphasize the need to calibrate biodiversity and (social) housing policy objectives more explicitly.

Cross-border Transmission of Climate Policies Through Global Production Networks
Marius Fourné
IWH Discussion Papers,
No. 19,
2025
Abstract
Climate policies do not operate in isolation but propagate through global production networks, affecting industries beyond national borders. This paper combines international input-output data with a granular instrumental variable approach to capture how foreign regulations transmit through upstream and downstream linkages. Distinguishing between market-based policies, non-market regulations, and technology support, the analysis shows that foreign climate policies can enhance domestic productivity, with effects shaped by industry characteristics and operating through technological adjustment along supply chains. The results underscore the importance of accounting for international spillovers when evaluating the economic impact of environmental regulation.

Trade Policy Sensitivity and Global Stock Returns: Evidence From the 2016 U.S. Presidential Election
Dien Giau Bui, Iftekhar Hasan, Chih-Yung Lin, Ngoc Thuy Mai, Chris Vaike
Journal of Banking and Finance,
Vol. 178 (September),
2025
Abstract
This paper introduces a novel measure to quantify firms’ sensitivity to shifts in bilateral trade flows between the United States and its trading partners. We exploit the 2016 U.S. presidential election as an exogenous shock to trade policy expectations and assess the stock market reactions of firms across 52 countries. Our findings indicate that firms with higher trade policy sensitivity experienced significantly more negative stock returns surrounding the election. These results are robust to variations in event windows, return model specifications, and alternative estimations of trade policy sensitivity.
