We investigate the gender gap in equity splits among members of founding teams using proprietary survey data on Japanese startups. The results reveal that, on average, female founder chief executive officers (CEOs) own 12 percentage points less equity than male founder CEOs. The gender equity gap is more pronounced in founding teams in which the founder CEO is a woman and the other founding members are men. However, the results vary depending on the founding teams’ characteristics. Notably, the gender equity gap is observed only in teams with individuals belonging to older generations and in teams from regions (prefectures) with great gender inequality. The findings indicate that gender norms influence the gender equity gap.

Financial distress is a prevalent issue among the youth. An influential stream of literature has argued that religion wields significant influence over human life. Using a representative sample of U.S. young people, we explore whether religiosity matters for financial distress. To deal with endogeneity issue, we exploit arguably exogeneous within-school variation in adolescents’ peers. By instrumenting an adolescent's own religiosity with the religiosity of their school peer group, we find that higher levels of religiosity causally and significantly reduce the likelihood of financial distress at young adulthood. Our results withstand a variety of robustness checks. To shed light on the mechanisms, we explore the impact of religiosity on an individual's sociability and various psychological attributes. We find that more religious individuals hold higher levels of self-control, a crucial attribute that aids in averting financial distress. Our study contributes to the literature by providing rigorous causal evidence that identifies religiosity as a meaningful predictor of reduced financial distress among young adults.

We study the impact of exchange rate volatility on cost efficiency and market structure in a cross-section of banks that have non-trivial exposures to foreign currency (FX) operations. We use unique data on quarterly revaluations of FX assets and liabilities (Revals) that Russian banks were reporting between 2004 Q1 and 2020 Q2. First, we document that Revals constitute the largest part of the banks’ total costs, 26.5% on average, with considerable variation across banks. Second, we find that stochastic estimates of cost efficiency are both severely downward biased – by 30% on average – and generally not rank preserving when Revals are ignored, except for the tails, as our nonparametric copulas reveal. To ensure generalizability to other emerging market economies, we suggest a two-stage approach that does not rely on Revals but is able to shrink the downward bias in cost efficiency estimates by two-thirds. Third, we show that Revals are triggered by the mismatch in the banks’ FX operations, which, in turn, is driven by household FX deposits and the instability of Ruble’s exchange rate. Fourth, we find that the failure to account for Revals leads to the erroneous conclusion that the credit market is inefficient, which is driven by the upper quartile of the banks’ distribution by total assets. Revals have considerable negative implications for financial stability which can be attenuated by the cross-border diversification of bank assets.

We show that investment decisions of country ETF market participants measured by ETF market order imbalances are driven by global shocks rather than local risks. We argue that the ETF price discovery mechanism is one of the key channels through which global shocks propagate to local economies, leading to increased return correlation with the U.S. market and limiting the benefits of international diversification. ETF order imbalance is predictive of the underlying MSCI index returns. The staggered introduction of country ETFs alters return correlations between underlying foreign and U.S. market indices. We find that countries with stronger ETF price discovery have higher comovement with the U.S. market lending further support for the proposed mechanism.

High secrecy cultures are characterized by a preference for confidentiality and non-disclosure of information. This study documents the impact of cultural differences in secrecy on firms’ access to credit. We use data from the World Bank Enterprise Surveys for a large sample of firms operating in 35 countries from 2010 to 2019. We show that firms operating in countries with higher levels of secrecy are less likely to apply for credit when they need it—they are more discouraged—and also less likely to receive credit when they do apply—they are more rationed. The underlying economic channels are greater opacity and corruption in cultures with high secrecy. The effect of cultural secrecy on credit discouragement and credit rationing is moderated by trust in banks, interpersonal trust, and firms’ financial dependence on external sources. We control for several potential alternative drivers and conduct several robustness tests. The results confirm that firms have better access to credit in cultures that promote transparency and information disclosure.

We examine the information content of off-exchange retail order flow relative to off-exchange institutional and on-exchange order flow. We use alternative sources of retail order identification and account for the fact that market opacity affects the order routing choices of both institutions and the brokers who sell retail orders. After controlling for volume effects, we find that retail order flow is more informed than off-exchange institutional order flow. Off-exchange price discovery comes mostly from retail order flow. However, on days with greater Robinhood activity, the information content of retail order flow drops. Our results reconcile some mixed findings in this literature.

This paper investigates the importance of U.S. macroeconomic news in driving low-frequency fluctuations in the term structure of interest rates in Canada, Sweden, and the U.K. We follow two complementary approaches: First, we apply a regression-based framework that aggregates the impact of daily macroeconomic news on bond yields to a lower quarterly frequency. Next, we estimate a macro-finance affine term structure model linking the daily news to lower-frequency changes in bond yields and its expectations and term premia components. Both approaches show that U.S. macroeconomic news is an important source of lower-frequency quarterly fluctuations in bond yields in these open economies, and even more important than their respective domestic macroeconomic news. Furthermore, the macro-finance model shows that U.S. macroeconomic news is particularly important in explaining low-frequency changes in the expectation components of the nominal, real, and break-even inflation rates.

We document that employee bankruptcy costs affect corporate capital structure decisions via their impact on the bargaining power of labor unions. We employ difference-in-differences and triple-difference research designs surrounding a major bankruptcy reform that increased personal bankruptcy costs. Our results suggest that, on average, this reform reduced unions’ bargaining power, resulting in a decrease in the financial leverage of unionized firms relative to nonunionized firms. Our results provide new evidence for a relatively unexplored determinant of capital structure—personal bankruptcy costs.

We use lottery jackpot winnings in a neighborhood as an exogenous shock to investing in stocks. We find that retail investors whose brokerages are near the stores that sell winning tickets buy more stocks than their counterparts after the shock. These purchases lead to lower returns. We use a survey to identify the behavioral factors like regretfulness and probability weighting that are the main drivers of our findings. Moreover, these investors tend to buy more lottery-like stocks, but the shock does not affect their selling decisions. Finally, we perform several falsification tests and robustness checks and find consistent results.

We provide for the first time the emerging market variance risk premium (EMVRP) from 2006 to 2023, based on nine emerging stock and option markets—Brazil, China, India, South Korea, Mexico, Poland, Russia, South Africa, and Taiwan. The EMVRP significantly predicts international stock returns and currency appreciation rates, especially for horizons longer than six months. This is in sharp contrast with the predictive pattern of the developed market variance risk premium (DMVRP), which is more important over horizons shorter than six months. These findings are consistent with an illustrative model incorporating partial market integration and heterogeneous economic uncertainty.
