摘要：We derive tight pricing kernel restrictions from options with same-day expiration (0DTEs). These restrictions concern the volatility of small and frequent asset price moves that the equity and options markets must agree on in a frictionless economy. Their violation leads to pseudo-arbitrage opportunities, characterized by nontrivial reward-to-risk ratios over arbitrarily short horizons and achieved by a combined position in 0DTEs and the underlying asset. Empirically, we find no evidence of fe...

摘要：Using two decades of French administrative data, we find that post-leveraged buyout (LBO), target firms reduce within-firm pay gaps while increasing profitability relative to control firms. Employee turnover drives the pay-gap reduction. In target and control firms alike, turnovers reduce average pay more at the top of the wage distribution than at the bottom because separated employees are paid more-new joiners less-than similar employees, especially among skilled employees. LBOs amplify this...

摘要：Young firms' contribution to aggregate employment has been underwhelming. We show that a similar trend is not apparent, however, in their contribution to aggregate sales or stock market capitalization, implying that these firms have exhibited a high average-to-marginal revenue product of labor. We study the implications of a gradual shift in the average-to-marginal revenue product of labor within a model of dynamic firm heterogeneity. We show that this shift provides (i) a unified explanation ...

摘要：Using confidential supervisory risk ratings, we document that banks increase risk after going public compared to a control group of banks that filed to go public but withdrew their filings for plausibly exogenous reasons. The increase in risk improves short-term performance at the expense of long-term performance. We argue that the increase in risk stems from pressure to maximize short-term stock prices and earnings once the bank is publicly traded. After going public, banks owned by investors...

摘要：Using an experiment in which 3.1 million bank customers were encouraged to save, we explore the mechanisms behind coholding liquid savings and credit card debt. Theoretically, we show that the joint responses of spending, saving, and borrowing to the nudge differ across economic models of coholding. Using machine learning techniques, we find that the most responsive individuals reduce spending and increase savings by 4.9% (206 USD PPP per month) while their credit card debt remains unchanged. ...

摘要：Using information in returns, we identify the stochastic process of consumption. We find that aggregate consumption reacts over multiple quarters to innovations spanned by financial markets. This persistent component accounts for over a quarter of consumption variation. These shocks command a large and significant risk premium, driving a large share of stocks' and a small yet significant fraction of bonds' time-series variation. Nevertheless, we find no support for stochastic volatility of con...

摘要：This paper studies whether social media sentiment predicts merger withdrawals. We find that a one-standard-deviation increase in social media sentiment after a merger announcement is associated with a 0.64 percentage point lower probability of withdrawal (16.6% of the average). This effect is unexplained by abnormal price reactions, traditional news, and analyst recommendations. Consistent with manager learning, the informativeness of social media strengthens after firms start corporate Twitte...

摘要：Short-sale costs eliminate the abnormal returns on asset pricing anomaly portfolios. While many anomalies persist out-of-sample before accounting for short-sale costs, they cannot be exploited with long-short strategies due to stock borrow fees. Using a comprehensive sample of 162 anomalies, the average long-short portfolio return is a significant 0.14% per month before short-sale costs, and the returns are due to the short leg. However, the average is -0.01% once returns are adjusted for borr...

摘要：This paper highlights the simple fact that households typically consist of multiple members who may hold divergent views, a fact that existing approaches to measuring and modeling household macroeconomic expectations largely abstract from. Using unique data on the macroeconomic expectations of both spouses, I document substantial intrahousehold disagreement about inflation, economic recessions, and stock market returns. I further show that household asset allocation decisions are shaped by dis...
