Using unique data from a leading peer-to-peer (P2P) lending platform, we investigate the link between past investment performance and choice of auto-investing tool. Our results suggest that investors who experience fewer defaults in the manual mode are more inclined to switch to automatic investment. Several factors account for this relationship, including investor inattention, decision speed, investment delegation, and experience. Regarding the latter, our results suggest that experienced investors are more likely to continue self-directed bidding, even if they have faced defaults in manual investments in the past. These investors may attribute their previous mistakes to their own actions rather than the limitations of the self-directed bids. Our results are robust to alternative specifications.

In this paper, we examine how employee lawsuits are related to firms’ business decisions. By using union-filed lawsuit data, we document that litigation increases the likelihood of firms downsizing their businesses. Furthermore, cases filed by unions lead to an increase in both the number of store closures and the number of employees affected by these closures. We demonstrate that violations related to labor have a significant negative impact on operating performance. Our findings reveal the fact that the cost of labor, damage to reputation, legal liabilities, and diverted resources resulting from litigation damages firms’ new business opportunities. Overall, our results highlight the importance of employee treatment at the workplace, which affects corporate decisions.

We investigate whether banks’ initial responses during the first wave of the COVID-19 pandemic in supporting their customers, communities, and governments were perceived as value-enhancing by investors. Using a unique responsible banking measure for a sample of the largest US and European commercial banks, we find a negative relationship between responsible bank behavior and stock market performance, particularly in the first wave of the pandemic. We also find that riskier banks were affected more negatively if they behaved responsibly. Overall, our findings show that banks’ responsible behavior during a crisis reduces, or at best is not relevant to, shareholder value.

In August 2020, the Federal Open Market Committee adopted a far-reaching Revised Statement on Longer-Run Goals and Monetary Policy Strategy. The framework contains two major changes from the original 2012 statement. First, policy decisions will attempt to mitigate shortfalls, rather than deviations, of employment from its maximum level. Second, the FOMC will implement Flexible Average Inflation Targeting. We show how to modify the rules in the Fed’s Monetary Policy Report to be consistent with the revised statement, how the pattern of falling behind the curve, pivot, and getting back on track in Fed policy during 2021 and 2022 could have been avoided by following inertial rules consistent with either the original or the revised statements, and how current and projected Fed policy for 2023 – 2026 is in accord with the prescriptions from inertial rules.

We design a model with banks of unequal size operating subject to liquidity requirements in an imperfectly-competitive deposit market. We show that large banks have stronger incentives than small ones to lobby in order to relax the liquidity requirements unless they bear significantly higher lobbying costs. Therefore, lobbying magnifies asymmetries between banks. Furthermore, we establish that the organization of influence activities matters. An industry-wide bank association for lobbying to relax the liquidity requirements suffers from an internal conflict of interest and cannot simultaneously benefit both large and small banks if these have identical lobbying cost functions.

Utilising climate-related narratives in conference call transcripts to measure firm-level exposure to climate risks, we examine the association between such exposure and the corporate cost of debt financing. Using a sample of 21 European countries from 2001 to 2020, we find that firms exposed to greater climate change experience higher debt costs. The impact is even more extreme when using climate-related opportunity and regulatory exposure measures. We further find critical economic channels through which the higher debt costs occur: financial development and credit supplies. Specifically, our findings hold only for firms in weakly developed financial markets and institutions as measured by the new broad-based multi-dimensional financial development indices. We also find some other conditioning factors. Firstly, the higher the carbon intensity level, the greater the debt cost a firm with more climate change exposure must pay. Secondly, debtholders appear to punish firms with high environmental and social disclosure that are exposed to more climate change. Thirdly, the findings are more pronounced in financially constrained firms.

Central banks around the world are exploring the possibility of Central Bank Digital Currencies (CBDCs) for retail and wholesale use. While no major economy is yet to fully introduced a CBDC, some countries have begun pilot programs. The purpose of this paper is to highlight the potential benefits and risks associated with CBDCs, including challenges and opportunities associated with proposed CBDC regulation in the United States and the European Union. The paper also discusses the CBDC landscape in Asia. It highlights some of the key findings of the research presented in this special issue on FinTech and CBDCs. Lastly, the paper offers thoughts for potential future research in areas such as the actual designs of CBDCs and their uses, ‘DeFi’ versus ‘CeFi’, their interoperability and stability, and concerns over cybercrime.

We employ the green revenue factors of firms, used in the computation of the FTSE Russell 1000 Green Revenues index to create corresponding green-adjusted share prices. We compute the firm betas, under both the standard and the green-adjusted share pricing. Our findings suggest that tilting of firm stock returns towards green finance could change temporarily asset pricing views. The Fama-French risk factors display very high correlations between the two settings. Nevertheless, there are some significant differences between standard and green-adjusted betas during periods associated with green activism and positive political decisions of financially supporting the global climate action.

We show how external credit market development can affect corporate social responsibility. Using a sample of US public firms over the period 1991–2010, we find that bank deregulation negatively affects CSR performance. We argue that deregulation-induced banking competition enhances credit accessibility, thereby reducing firms’ incentives to pursue CSR as a means of securing stakeholder rewards. Empirical evidence shows that firms increase their use of debt financing in response to the intensified banking competition, and these firms experience a more pronounced decline in CSR performance. We alleviate the potential concern that the observed decline in CSR could be attributed to changes in bank monitoring following deregulation. Further analyses find that firms reduce CSR regardless of their material nature, suggesting that the primary driver of CSR could be the trade-off between costs and returns. Overall, our findings shed light on the strategic motives of CSR, which exhibits adaptability in response to business dynamism.

In this paper, we investigate price exuberance episodes in the main UK commercial real estate sectors – retail, offices and industrials - over the period December 1986–April 2022. Using the Backward Supremum Augmented Dickey Fuller approach of Phillips et al. (2015a,b), we find that episodes of price explosiveness are asynchronous across sectors with only common phase being the period 2003–2007. We also conduct a multivariate probit analysis to identify factors that indicate the occurrence of price exuberance episodes and generate early signals for possible price bubble building. The predictors for price explosiveness differ by sector with more consistent signals obtained from the yield curve for retail and industrials, rent growth for offices and industrials, and inflation for retail and offices. A key implication of this study is that the study of price exuberance and bubbles in private real estate should be sector specific even within the same country.
