We find that firms with CFOs who have extensive social connections within the finance industry hold less precautionary cash. CFO connections matter more than CEO connections, reflecting the preeminence of CFOs among C-level executives in cash management and negotiating access to corporate finance. Firms reduce the proportion of assets held in cash by seven percentage points in the two years following CFO turnover and the appointment of a CFO with finance industry connections. The stock market valuation of incremental cash holdings of firms with well-connected CFOs is lower than for other firms, consistent with investor recognition of CFO social capital as an alternative means to address constraints on external capital.

We examine the economics that underlie retail trading costs around discount brokers’ widespread adoption of zero commission trading in October 2019. Our analysis of participating brokers’ Rule 606 filings and financial statements reveals little change in payment for order flow, which suggests brokers absorbed the cost of eliminating commissions in a competitive environment. We then perform a difference-in-differences analysis of effective spreads and report economically trivial changes in retail execution costs around the commission change. Finally, we assess the total trading costs of an aggregate retail portfolio compared to a host of counterfactuals. We find that following the zero-commission change, total retail transaction costs dropped substantially even under the extreme counterfactual that these traders pay exchange quoted spreads and receive zero price improvement. Our findings support the brokerage industry's claim that dropping commissions helped retail investors and should ease regulators’ concerns to the contrary.

Fears of immigrants as a threat to public health have a long and sordid history. At the turn of the 20th century, when immigrants made up one-third of the population in crowded American cities, contemporaries blamed high urban mortality rates on the newest arrivals. We evaluate how the implementation of country-specific immigration quotas in the 1920s affected urban health. Cities with larger quota-induced reductions in immigration experienced a persistent decline in mortality rates, driven by a reduction in deaths from infectious diseases. The unfavourable living conditions immigrants endured explains the majority of the effect as quotas reduced residential crowding and mortality declines were largest in cities where immigrants resided in more crowded conditions and where public health resources were stretched thinnest.

We estimate the effect of carbon pricing policy on bank credit to greenhouse-gas-emitting firms. Our analyses exploit the geographic restrictions inherent in California’s cap-and-trade bill and a discontinuity in the embedded free permit threshold of the federal Waxman-Markey cap-and-trade bill. Affected high emission firms face shorter loan maturities, lower access to permanent forms of bank financing, higher interest rates, and higher participation of shadow banks in their lending syndicates. These effects are concentrated among private firms, while credit terms of public firms are largely unaffected. Overall, we show that banks respond quickly to realizations of transition risk.

Using supervisory data from large U.S. bank holding companies (BHCs), we document that operational loss recovery rates decrease in macroeconomic downturns. This procyclical relationship varies by business lines and loss event types and is robust to alternative data aggregations, macroeconomic measurement horizons, subperiod partitions and estimation methodologies. Further analysis shows that resource constraints faced by BHC risk management functions is a plausible explanation for these patterns. Our findings offer new evidence on how economic shocks transmit to banking industry losses with implications for risk management and supervision.

Few studies have examined the reputational damage of environmental and social (E&S) scandals ex-post. Using an international sample of mergers and acquisitions (M&A) across 18 countries, we examine whether heightened E&S risks arising from acquirers’ E&S incidents affect the cost of acquisition. We find that the severity of the incident increases acquisition premium and this effect is explained by incident acquirers compensating target shareholders for heightened reputation risks, rather than seeking to repair their reputation through the acquisition. At the country level, incident acquirers in countries with stronger E&S standards and policies also experience higher premium. Further analysis shows that E&S incidents reduce shareholder value upon the announcement of an M&A and increase the time taken for M&A completion. Firms are less likely to make acquisitions after experiencing an E&S incident, but this decision depends on the cost of delay. Finally, we show that the adverse impact on acquisitions dissipates after six months.

Rational respondents to economic surveys may report as a point forecast any measure of the central tendency of their predictive distribution, e.g. the mean, median, or mode. We propose tests of forecast rationality when the measure used by the respondent is unknown. We overcome an identification problem that arises when the centrality measures are in a local neighborhood of each other, as is the case for approximately symmetric distributions. We apply our tests to income forecasts from the FRBNY's Survey of Consumer Expectations. We find these forecasts are rationalizable as mode forecasts, but not as mean or median forecasts.

Political identity and partisanship are salient features of today's society. Using deeds records and voter rolls, we show that current residents are more likely to sell their homes when opposite‐party neighbors move in nearby than when unaffiliated or same‐party neighbors do. This is especially true when the new neighbors are politically active, consistent with an animosity between parties mechanism. We conclude that affective polarization is not limited to purely political settings and affects one of the household's most important financial decisions, their home transactions.

Measuring the prevalence of active SARS-CoV-2 infections in the general population is difficult because tests are conducted on a small and nonrandom segment of the population. However, hospitalized patients are tested at very high rates, even those admitted for non-COVID reasons. We show how to use information on testing of non-COVID hospitalized patients to obtain tight bounds on population prevalence, under conditions weaker than those usually used. We apply our approach to the population of test and hospitalization data for Indiana, and we validate our approach. Our bounds could be constructed at relatively low cost, and for other heavily tested populations.

We study the influence of supervisors on employee misconduct at branches of U.S. financial institutions. Individual supervisor fixed effects explain twice as much variation in branch misconduct as firm fixed effects. Supervisor influence is concentrated in firms that theory suggests are most likely to delegate authority—firms with complex operations, distant branches, and trustworthy supervisors. Supervisors affect misconduct through their personnel decisions, attention to employees with past misbehavior, and ethics and industry rules training. After major internal control improvements, supervisor influence declines. Our results illustrate how supervisors influence misconduct above and beyond firm-level factors.
