Random assignment is insufficient for measured treatment responses to recover causal effects (comparative statics) in dynamic economies. We characterize analytically bias probabilities and magnitudes. If the policy variable is binary there is attenuation bias. With more than two policy states,...

We survey over 1,000 institutional and corporate venture capitalists (VCs) at more than 900 different firms to learn how their decisions and investments have been affected by the COVID-19 pandemic. We compare their survey answers to those provided by a large sample of VCs in early 2016 and...

Using a novel dataset of U.S. buyout and VC investments, we study the informativeness of fund managers' interim valuation reports about portfolio companies on final outcomes. We find that when investors assess the performance of individual portfolio companies, they can do better than just...

Using an extensive new data set on corporate bond defaults in the U.S. from 1866 to 2010, we study the macroeconomic effects of bond market crises and contrast them with those resulting from banking crises. During the past 150 years, the U.S. has experienced many severe corporate default crises...

We study corporate bond default rates using an extensive new data set spanning the 1866-2008 period. We find that the corporate bond market has repeatedly suffered clustered default events much worse than those experienced during the Great Depression. For example, during the railroad crisis of...

We survey 885 institutional venture capitalists (VCs) at 681 firms to learn how they make decisions across eight areas: deal sourcing; investment selection; valuation; deal structure; post-investment value-added; exits; internal firm organization; and relationships with limited partners. In selecting...

We study the relation between leverage and corporate tax rates using an extensive data set constructed from all corporate income tax returns filed with the IRS from 1926 to 2009. This data set includes financial statement data from millions of private and public corporations of all sizes. We...

We develop a model of the joint capital structure decisions of banks and their borrowers. Strikingly high bank leverage emerges naturally from the interplay between two sets of forces. First, seniority and diversification reduce bank asset volatility by an order of magnitude relative to that of...

This paper documents the puzzling evidence that a substantial number of large public non-financial US firms follow a zero-debt policy. Over the 1962-2009 period, on average 10.2% of such firms have zero debt and almost 22% have less than 5% book leverage ratio. Neither industry nor size can...

We provide a dynamic model of an industry in which agents strategically time liquidation decisions in an effort to protect their reputations. As in traditional models, agents delay liquidation attempting to signal their quality. However, when the industry faces a common shock that...
