We develop a dynamic model with time variation in external equity financing costs and show that variation in these costs is important for the model to quantitatively capture the joint dynamics of firms' asset prices, real quantities, and financial flows in the U.S. economy. Growth firms and high...

A popular interpretation of the Rational Expectations/Efficient Markets hypothesis states that, if it holds, market valuations must follow a random walk; hence, the hypothesis is frequently criticized on the basis of empirical evidence against such a prediction. Yet this reasoning incurs what we...

A popular interpretation of the Rational Expectations/Efficient Markets hypothesis states that, if the hypothesis holds, then market valuations must follow a random walk. This postulate has frequently been criticized on the basis of empirical evidence. Yet the assertion itself incurs what we...

During the recent financial crisis, there was a dramatic spike, across all industries, in the volatility of individual firm share prices after adjustment for movements in the market as a whole. In this Article, we demonstrate that a similar spike has occurred with each major downturn in the...

The booms and busts in U.S. stock prices over the post-war period can to a large extent be explained by fluctuations in investors' subjective capital gains expectations. Survey measures of these expectations display excessive optimism at market peaks and excessive pessimism at market throughs....

A four-factor model is used to measure the interdependence's co-movement and crisis' contagion effect on portfolio returns of 23 Taiwanese industries during tranquil and the U.S. subprime mortgage crisis periods. By incorporating the control variables of economic and financial fundamentals, we...

This paper studies the US equity market during the COVID-19 period in the first half of 2020. There is a record rise, then a record fall in prices and then a record recovery. Throughout the period there was extreme volatility and much short term momentum with fear and greed alternating. The VIX...

We construct novel proxies of physical and transition climate risks by conducting textual analysis of climate-change news over the period 2000-2018. This analysis uncovers four textual variables related to the topics of U.S. climate policy, international summits, natural disasters, and global...

This study explores whether the credit risk anomaly exhibits option-like behavior similar to the momentum anomaly. Employing a market-timing regression model as in Daniel and Moskowitz (2013), it finds that the inverted credit risk spread indeed displays option-like behavior in bear market...

This paper explores the effect of oil price fluctuations on the stock returns of U.S. oil firms using a strategy of identification through heteroskedasticity exploiting the 2020 oil crash. Results are twofold. First, we find that a decline in oil prices statistically significantly reduces stock...
