摘要：Prior studies find that a strategy that buys high-beta stocks and sells low-beta stocks has a significantly negative unconditional capital asset pricing model (CAPM) alpha, such that it appears to pay to bet against beta. We show, however, that the conditional beta for the high-minus-low beta portfolio covaries negatively with the equity premium and positively with market volatility. As a result, the unconditional alpha is a downward-biased estimate of the true alpha. We model the conditional ...

摘要：We examine heterogeneity in depositor responses to solvency risk using depositor-level data for a bank that faced two different runs. We find that depositors with loans and bank staff are less likely to run than others during a low-solvency-risk shock, but are more likely to run during a high-solvency-risk shock. Uninsured depositors are also sensitive to bank solvency. In contrast, depositors with older accounts run less, and those with frequent past transactions run more, irrespective of the...

摘要：The risk and return trade-off, the cornerstone of modern asset pricing theory, is often of the wrong sign. Our explanation is that high-beta assets are prone to speculative overpricing. When investors disagree about the stock market's prospects, high-beta assets are more sensitive to this aggregate disagreement, experience greater divergence of opinion about their payoffs, and are overpriced due to short-sales constraints. When aggregate disagreement is low, the Security Market Line is upward-...

摘要：We use novel data from a leading online job search platform to examine the impact of corporate distress on firms' ability to attract job applicants. Survey responses suggest that job seekers accurately perceive firms' financial condition, as measured by companies' credit default swap prices and accounting data. Analyzing responses to job postings by major financial firms during the Great Recession, we find that an increase in an employer's distress results in fewer and lower quality applicants...

摘要：We show that consumption-based asset pricing models with time-separable preferences generate realistic amounts of stock price volatility if one allows for small deviations from rational expectations. Rational investors with subjective beliefs about price behavior optimally learn from past price observations. This imparts momentum and mean reversion into stock prices. The model quantitatively accounts for the volatility of returns, the volatility and persistence of the price-dividend ratio, and...

摘要：Asset prices contain information about the probability distribution of future states and the stochastic discounting of those states as used by investors. To better understand the challenge in distinguishing investors' beliefs from risk-adjusted discounting, we use Perron-Frobenius Theory to isolate a positive martingale component of the stochastic discount factor process. This component recovers a probability measure that absorbs long-term risk adjustments. When the martingale is not degenerat...

摘要：Economic analyses of corporate finance, money, and sovereign debt are largely considered separately. I introduce a novel corporate finance framing of sovereign finance based on the analogy between fiat liabilities for sovereigns and equity for corporations. The analysis focuses on financial constraints at the country level, making explicit the trade-offs involved in relying on domestic versus foreign-currency debt to finance investments or government expenditures. This framing provides new ins...

摘要：We present evidence that financing frictions adversely impact investment in work-place safety, with implications for worker welfare and firm value. Using several identification strategies, we find that injury rates increase with leverage and negative cash flow shocks, and decrease with positive cash flow shocks. We show that firm value decreases substantially with injury rates. Our findings suggest that investment in worker safety is an economically important margin on which firms respond to f...

摘要：This paper characterizes U.S. consumption dynamics from the perspective of a Bayesian agent who does not know the underlying model structure but learns over time from macroeconomic data. Realistic, high-dimensional macroeconomic learning problems, which entail parameter, model, and state learning, generate substantially different subjective beliefs about consumption dynamics compared to the standard, full-information rational expectations benchmark. Beliefs about long-run dynamics are volatile...
