We use a natural experiment in the form of 121 staggered changes in corporate income tax rates across U.S. states to show that tax considerations are a first-order determinant of firms' capital structure choices. Over the period 1990-2011, firms increase long-term leverage by 104 basis points on...

Using 113 staggered changes in corporate income tax rates across U.S. states, we provide evidence on how taxes affect corporate risk-taking decisions. Higher taxes reduce expected profits more for risky projects than for safe ones, as the government shares in a firm's upside but not in its...

Using a unique dataset of private equity funds over the last two decades, this paper analyzes the cash flow, return, and risk characteristics of private equity. We document the draw down and capital return schedules for the typical private equity fund, and show that it takes several years for...

Motivated by concerns that the patent system is hindering innovation, particularly for small inventors, this study investigates the bright side of patents. We examine whether patents help startups grow and succeed using detailed micro data on all patent applications filed by startups at the U.S....

Over the past two decades, the U.S. stock market has been shrinking as the public firm model has begun to fall out of favor. We develop a political economy model of delistings to study the wider economic consequences of this trend. We show that the private and social incentives to delist firms...

We study the efficiency of capital allocations at state-controlled and privately owned business groups in China. Using highly granular data on within-group capital transfers, we document stark differences: while private groups allocate more capital to units with better investment opportunities,...

Do corporate tax increases destroy jobs? And do corporate tax cuts boost employment? Answering these questions has proved empirically challenging. We propose an identification strategy that exploits variation in corporate income tax rates across U.S. states. Comparing contiguous counties...

Limits to arbitrage play a central role in behavioral finance. They are thought to interfere with arbitrage processes so that security prices can deviate from true values for extended periods of time. We describe a recent financial innovation that allows limits to arbitrage to be sidestepped,...

Is greater trading liquidity good or bad for corporate governance? We address this question both theoretically and empirically. We solve a model consisting of an optimal IPO followed by a dynamic Kyle market in which the large investor's private information concerns her own plans for taking an...

Financial constraints are not directly observable, so empirical research relies on indirect measures. We evaluate how well five popular measures (paying dividends, having a credit rating, and the Kaplan-Zingales, Whited-Wu, and Hadlock-Pierce indices) identify firms that are financially...
