We assess the role of human discretion in lending outcomes using a randomized, controlled experiment. The lenders in our sample utilize a third party, machine-generated credit model as an input in their decision. We design a new feature for the credit-scoring platform – the slider feature – which invites lenders to incorporate additional discretion in their decision by adjusting the machine-based recommendation. We compare the loan outcomes for treatment lenders that randomly get the slider, relative to a control group. The treatment group's adjustments are predictive of forward looking portfolio characteristics – they show larger declines in future portfolio-level credit risk and larger increases in future sales orders, relative to the control group. The effects of our intervention are more pronounced when borrowers do not have social media accounts and in competitive markets. Our study provides insights about the role of human decisions, given the rapid evolution of machine-based lending models.

Do industries use advertising strategically when subject to the threat of political costs? Communication via advertising can assuage public concerns, which, in turn, reduces the incentives for elected officials to impose regulations on the industry. We identify expected political costs using cases of repeated industry testimony at congressional hearings. To disentangle strategic advertising in response to the threat of political costs from advertising for other reasons (e.g., reputation building or to generate sales), we exploit the fact that only politicians overseeing industry-relevant hearings can impose costs on a given industry. We find that subsequent to these hearings, affected industries increase their advertising by 132% more in the electorates of the politicians overseeing the hearings, relative to the increase in the electorates of other politicians. The strategic increase in advertising is magnified in the electorates served by the most senior politicians on the committees and those with the most politically engaged citizens. The increase is also pronounced in election years, when the hearings are longer, contain more negative language, or include a higher proportion of legislation-related words. Moreover, our results are not driven by politicians’ decisions to serve on committees relevant to their local-area firms. In sum, our findings provide novel evidence about corporate communication with non-investor stakeholders.

Our study reports evidence on the dynamic effects of client switches on auditor reputations and fee premia. Offices of large accounting firms that lose (gain) major industry clients experience a reputation shock leading to more same‐industry client losses (gains) over the next two years. There is also a shift in audit fees charged to other same‐industry clients when a major client loss (gain) results in an audit office losing (gaining) city‐level industry leadership. A major client loss or gain also creates a short‐term capacity shock to an audit office's ability to supply high‐quality audits. However, there is no evidence of reputation spillovers to other‐industry clients in the audit office, or to clients in other offices of the accounting firm.

We study health-care provider agency and optimal payments, considering an expensive medication for dialysis patients. Using Medicare claims data we estimate a structural model of treatment decisions, in which providers differ in their altruism and marginal costs, and this heterogeneity is unobservable to the government. In a novel application of nonlinear pricing methods, we empirically characterize the optimal contracts in this environment. The optimal contracts eliminate medically excessive dosages and reduce expenditures, resulting in approximately $300 million in annual gains from better contracting. This approach could be applied to a broad class of problems in health-care payment policy.

We investigate whether corporate insiders attempt to circumvent insider trading restrictions by using their private information to facilitate trading in economically linked firms, a phenomenon we call “shadow trading.” Using measures of informed trading to proxy for shadow trading, we find increased levels of informed trading among business partners and competitors before a firm releases private information. To rule out alternative explanations, we examine two shocks to insiders' incentives to engage in shadow trading: high-profile regulatory enforcement against conventional insider trading, and staggered changes to their outside employment opportunities. Finally, we document attenuated levels of informed trading among business partners and competitors when firms prohibit shadow trading. Overall, we provide evidence that shadow trading is an undocumented and widespread mechanism that insiders use to avoid regulatory scrutiny.
