NBER Working Papers and Publications

June 2020The Effectiveness of Life-Preserving Investments in Times of COVID-19
with Jules H. van Binsbergen: w27382
We analyze the effectiveness of preventive investments aimed at increasing agents' life expectancy, with a focus on influenza and COVID-19 mitigation. Maximizing overall life expectancy requires allocating resources across hazards so as to equalize investments' marginal effectiveness. Based on estimates for the marginal effectiveness of influenza vaccines, we determine the level of COVID-19 mitigation investments that would imply such equalization. Given current projections for COVID-19 mitigation costs, our results suggest that wide-spread influenza vaccination would be an effective life-preserving investment.
To Pool or Not to Pool? Security Design in OTC Markets
with Vincent Glode, Ruslan Sverchkov: w27361
We study security issuers' decision whether to pool assets when facing counterparties endowed with market power, as is common in over-the-counter markets. Unlike in competitive markets, pooling assets may be suboptimal in the presence of market power - both privately and socially - in particular, when the potential gains from trade are large. In these cases, pooling assets reduces the elasticity of trade volume in the relevant part of the payoff distribution, exacerbating inefficient rationing associated with the exercise of market power. Our results shed light on recently observed time-variation in the prevalence of pooling in financial markets.
March 2017Real Anomalies
with Jules H. van Binsbergen: w23238
We examine the importance of asset pricing anomalies (alphas) for the real economy. We develop a novel quantitative model with lumpy investment that features such informational inefficiencies and yields closed-form solutions for cross-sectional distributions of firm dynamics. Our findings indicate that anomalies can cause material real inefficiencies, raising the possibility that agents that help eliminate them can provide significant value added to the economy. The framework reveals that alphas alone are poor indicators of real distortions, and that efficiency losses depend on the persistence of alphas, the amount of mispriced capital, and the Tobin's q of firms affected.
