Financial constraints are fundamental to empirical research in finance and economics. We propose two tests to evaluate how well measures of financial constraints actually capture constraints. We find that firms typically classified as constrained do not in fact behave as if they were...

We investigate whether short-termism distorts the investment decisions of stock market listed firms. To do so, we compare the investment behavior of observably similar public and private firms using a new data source on private U.S. firms, assuming for identification that closely held private...

We document sizeable and surprising 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 substantially less and are less responsive to changes in investment opportunities compared to...

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...

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...

We structurally estimate a set of firm- and time-varying measures of the magnitude of external financial constraints. By considering the entire capital structure—equity and debt of various maturities—we identify on which external financing margin(s) a firm is constrained at a given point in...

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...

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....
