The U.S. mortgage market exhibits competitive instability in which some lenders rapidly emerge from the fringe to substantial market shares. Using inferred discontinuities in application acceptance models to generate local lending shocks, we analyze the impact on a lender of a surge in originations by its competitors. We show that the quickest-growing (but not the largest) competitors divert applications and originations from other lenders. Facing a quickly growing competitor, lenders charge higher interest rates, partially because of the increased risk of their loans. Loan performance suffers for other lenders as the quickest-growing competitor’s originations increase.

Prime brokers play an important role in intermediating arbitrage capital to hedge funds. A fund’s peer-group ranking, relative to funds that share the same prime broker, significantly affects how investors respond to its past performance. I decompose the standard performance-flow relationship into two components: (1) flows that respond to overall performance rank, and (2) flows that respond to relative (within prime broker) performance rank. Strong relative rank drives fund in-flows, while poor overall rank drives out-flows. These results suggest that prime brokers intermediate about 40% of the standard performance-flow relationship.

We study bank policies to limit lending to companies engaged in mountaintop removal (MTR) coal mining, a form of coal extraction that has raised many environmental concerns. Using the staggered introduction of these policies, we document that these policies did not lead to meaningful changes in average bank lending or MTR mining. However, larger banks, banks that are under media pressure, and banks operating in the affected states are more likely to reduce MTR loans. Our results are consistent with the hypothesis that banks announced these policies under pressure and to improve their green credentials.

Many of the events that trigger clawback provisions are associated with risky corporate policies and variable performance outcomes. We propose and test the hypothesis that clawback provisions motivate managers to reduce firm risk. Panel ordinary least squares, general method of moments with instrumental variables, and propensity square matching models all indicate that clawback provisions decrease the volatility of stock returns. The channels that connect clawback presence to firm risk include more conservative investment and financial policies. The clawback-induced reduction in risk-taking appears to benefit shareholders on average. The gains from reduced risk-taking are larger for firms with fewer growth options, lower R&D, and prior wrongdoing.

This paper studies the effect of timing and commitment of verification in a principal-agent relationship with moral hazard. To acquire additional information about the agent’s behavior, the principal possesses a costly technology that produces a noisy signal about the agent’s effort choice. The precision of this signal is affected by the principal’s verification effort. Two verification procedures are discussed: monitoring where the principal verifies the agent’s behavior simultaneously with his effort choice and auditing where the principal can condition her verification effort on the realized outcome. As it is well known, the principal prefers to audit the agent’s behavior if she can commit to her verification effort at the time of contracting. The main contribution of this paper is to highlight the importance of commitment by the principal to her verification effort. In particular, I show that, when the principal cannot commit to her verification effort ex-ante, the principal strictly prefers monitoring to auditing if the gains from choosing high effort are sufficiently high.

We examine an undercover Securities and Exchange Commission (SEC) investigation into the manipulation of financial news on social media. While fraudulent news had a direct positive impact on retail trading and prices, revelation of the fraud by the SEC announcement resulted in significantly lower retail trading volume on all news, including legitimate news, on these platforms. For small firms, volume declined by 23.5% and price volatility dropped by 1.3%. We find evidence consistent with concerns of fraud causing the decline in trading activity and price volatility, which we interpret through the lens of social capital, and attempt to rule out alternative explanations. The results highlight the indirect consequences of fraud and its spillover effects that reduce the social network’s impact on information dissemination, especially for small, opaque firms.

We investigate the puzzle of widespread participation in cryptocurrency pump-and-dump manipulation schemes. Unlike stock market manipulators, cryptocurrency manipulators openly declare their intentions to pump specific coins, rather than trying to deceive investors. Puzzlingly, people join in despite negative expected returns. In a simple framework, we demonstrate how overconfidence and gambling preferences can explain participation in these schemes. Analyzing a sample of 355 cases in 6 months, we find strong empirical support for both mechanisms. Pumps generate extreme price distortions of 65% on average, abnormal trading volumes in the millions of dollars, and large wealth transfers between participants.

Dividends are a key mechanism for shareholders to discipline managers and mitigate agency conflicts. This study examines whether the volatility of tax payments is associated with dividend payouts. Consistent with the predictions, results suggest that firms with more volatile tax payments are less likely to pay dividends overall and their dividends are lower in magnitude when doing so. These effects are economically significant and incremental to a firm's operating risk. The link between volatile tax payments and the likelihood of dividend payouts is weaker for firms that distribute dividends to alleviate agency conflicts. Similarly, the link between volatile tax payments and the amount of dividend payouts is weaker for firms that hold more cash for tax reasons. Taken together, these findings add to our understanding of the economic consequences of volatile tax payments and the determinants of dividend payouts.
