We evaluate differences in investment behavior between stock market listed and privately held firms in the U.S. using a rich new data source on private firms. Listed firms invest less and are less responsive to changes in investment opportunities compared to observably similar, matched private...

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...

We provide evidence on the value of patents to startups by leveraging the quasi-random assignment of applications to examiners with different propensities to grant patents. Using unique data on all first-time applications filed at the U.S. Patent Office since 2001, we find that startups that win...

The deregulation of securities laws|in particular the National Securities Markets Improvement Act (NSMIA) of 1996|has increased the supply of private capital to late-stage private startups, which are now able to grow to a size that few private firms used to reach. NSMIA is one of a number of...

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....

We examine whether stock market-listed firms in the U.S. invest suboptimally due to agency costs resulting from separation of ownership and control. We derive testable predictions to distinguish between underinvestment due to rational “short-termism” and overinvestment due to “empire...

Financial constraints are fundamental to empirical research in finance and economics. We propose two novel tests to evaluate how well measures of financial constraints actually capture constraints. We find that firms classified as constrained according to five popular measures do not in fact...
