Using comprehensive data on U.S. corporate bond trades since 2002, we find evidence that retail bond investors overrely on untimely credit ratings to their financial detriment. Specifically, they appear to select bonds by first screening on a credit rating and then sorting by yield, buying the highest-yielding bonds within each rating level. Because yields lead credit rating changes, selecting on yield-within-rating means that retail investors systematically trade in the opposite direction of changing fundamentals, buy in advance of credit downgrades and defaults, and materially underperform a diversified portfolio. Our study provides new evidence of ill-informed retail trading in a market that is thought to be relatively sophisticated, corroborates regulators’ concerns about investor overreliance on credit ratings, and contributes to the academic literature on the roles and consequences of credit ratings in debt markets.

We study the effect of hearing cases alongside female judicial colleagues on the probability that a federal judge hires a female law clerk. Federal judges are assigned to judicial panels at random and have few limitations on their choices of clerks. Using a unique dataset of federal case records merged with judicial hiring information, we find a significant effect of the fraction of copanelists who are female on a male judge’s likelihood of hiring a female clerk. This finding suggests that increases in the diversity of the upper rungs of a profession can create opportunities at the entry level.

We assess the welfare consequences of occupational licensing for workers and consumers. We estimate a model of labour market equilibrium in which licensing restricts labour supply but also affects labour demand via worker quality and selection. On the margin of occupations licensed differently between U.S. states, we find that licensing raises wages and hours but reduces employment. We estimate an average welfare loss of 12% of occupational surplus. Workers and consumers respectively bear 70% and 30% of the incidence. Higher willingness to pay offsets 80% of higher prices for consumers, and higher wages compensate workers for 60% of the cost of mandated investment in occupation-specific human capital. Welfare effects appear more favourable in occupations in which licensing is more common.

We model optimal treatment assignment in programs with a limited number of seats and study how the presence of peer effects impacts the optimal allocation rule. We then use data from a randomized control trial to show evidence that there are large peer effects in the context of job training for disadvantaged adults in the United States. Finally, we combine the model and the empirics to show that the program would have had a much greater impact if the assignment choices had accounted for the peer effects.

We study the equilibrium implications of a multi-asset economy in which asset managers performance is tied to different benchmarks, reflecting heterogeneity in their investment mandates. Fluctuations in the capital asset managers invest for benchmarking purposes, scaled by the size of the economy, induce price pressure that results in negative spillovers across assets. We characterize a rich structure of asset price comovement within and across benchmarks by analyzing shock elasticities and cross-elasticities of price-dividend ratios. Evidence on the heterogeneity of mutual fund mandates and the benchmarking-induced return comovement across cap-style and industry-sector portfolios corroborates the model assumptions and predictions.

Between March and August 2020, S&P and Moody’s downgraded approximately 25% of collateral feeding into CLOs and only 2% of tranche values, with rating actions concentrating in junior tranches. Both S&P and Moody’s modeling indicate that the impacts should have been considerably larger, especially for higher-rated tranches. Neither changes in correlation nor the accumulation of pre-COVID-19 protective cushions can explain the downgrade asymmetry on upper tranches. Instead, CLO managers repositioned their collateral pools to dampen the negative credit shock and rating agencies incorporated qualitative adjustments in their CLO ratings. Important potential policy and market implications from these findings are discussed.

This paper explores the impact of water quality on mortality by exploiting a natural experiment: the rise of tea consumption in eighteenth century England. This resulted in an unintentional increase in consumption of boiled water, thereby reducing mortality rates. The methodology uses two identification strategies tying areas with lower initial water quality to larger declines in mortality rates after tea drinking became widespread and following larger volumes of tea imports. Results are robust to the inclusion of controls for income and access to trade. The hypothesis is further bolstered by suggestive evidence from cause specific deaths and early childhood mortality.

We use multiple methods to examine how depletion and auditors' skeptical dispositions interact to affect auditors' challenging of managers in negotiations over financial statement amounts. We expect auditors are likely depleted from effortfully exercising self‐regulation during the busy times when these negotiations occur. Individuals in a depleted state tilt toward natural, less effortful behaviors. Thus, we posit that the effects of depletion will diverge depending on the auditor's skeptical disposition—a determinant of how natural or effortful they will find the skeptical behaviors (e.g., challenging) versus client service behaviors (e.g., maintaining the client relationship and audit efficiency) required for negotiations. We predict that client service auditors (i.e., low skeptics) will challenge managers less in negotiations when depleted versus non‐depleted, while high skeptic auditors will challenge more when depleted. We test this interactive prediction in an abstract experiment where we manipulate depletion and measure auditors' skeptical dispositions using trait skepticism. Findings support our predictions. We also develop a new measure of auditors' client service–skeptic disposition based on the skepticism literature that adds nuance to the traditional lower versus higher skeptic labels. In a second study, interviews with audit partners validate the realism of our depletion and client service–skeptic constructs and corroborate our experimental findings. Our study sheds light on depletion effects in auditors' negotiations with their clients and how the effects differ based on auditor personalities.
