What Is a Patent Worth? Evidence from the U.S. Patent “Lottery”

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 patent “lottery” by drawing lenient examiners have, on average, 55% higher employment growth and 80% higher sales growth five years later. Patent winners also pursue more, and higher quality, follow-on innovation. Winning a first patent boosts a startup’s subsequent growth and innovation by facilitating access to funding from venture capitalists, banks, and public investors.     

Bank Capital Regulation of Trading Portfolios: An Assessment of the Basel Framework

In setting minimum capital requirements for trading portfolios, the Basel Committee on Banking Supervision (1996, 2011a, 2013) initially used Value‐at‐Risk (VaR), then both VaR and stressed VaR (SVaR), and most recently, stressed Conditional VaR (SCVaR). Accordingly, we examine the use of SCVaR to measure risk and set these requirements. Assuming elliptically distributed asset returns, we show that portfolios on the mean‐SCVaR frontier generally lie away from the mean‐variance (M‐V) frontier. In a plausible numerical example, we find that such portfolios tend to have considerably higher ratios of risk (measured by, e.g., standard deviation) to minimum capital requirement than those of portfolios on the M‐V frontier. Also, we find that requirements based on SCVaR are smaller than those based on both VaR and SVaR but exceed those based on just VaR. Finally, we find that requirements based on SCVaR are less procyclical than those based on either VaR or both VaR and SVaR. Overall, our paper suggests that the use of SCVaR to measure risk and set requirements is not a panacea.     

PRIVATE EDUCATION IN INDIA: A NOVEL TEST OF CREAM SKIMMING

Students in private schools routinely outperform those in public schools both in the United States and around the world. But do private schools make students better or do they simply cream skim better students? In this article I take advantage of the remarkable fact that in many districts in India a majority of students attend private schools. As the private share of school enrollment increases, cream skimming becomes less plausible as the explanation for a higher rate of achievement in private schools. Evidence for cream skimming is found when the private share of schooling is low, in the range of 0–15%, and thus private schools have a large public pool from which to skim. But the private effect on achievement does not appear to diminish greatly even in districts where more than 70% of students are in private schools. Most importantly, mean scores taken over the entire population of students, private and public, increase with the share of private schooling. These findings support a significant productivity effect of private schools. (JEL I25, I2, L33)     

Networking as a Barrier to Entry and the Competitive Supply of Venture Capital

We examine whether strong networks among incumbent venture capitalists (VCs) in local markets help restrict entry by outside VCs, thus improving incumbents' bargaining power over entrepreneurs. More densely networked markets experience less entry, with a one‐standard deviation increase in network ties among incumbents reducing entry by approximately one‐third. Entrants with established ties to target‐market incumbents appear able to overcome this barrier to entry; in turn, incumbents react strategically to an increased threat of entry by freezing out any incumbents who facilitate entry into their market. Incumbents appear to benefit from reduced entry by paying lower prices for their deals.     

The Value of Financial Flexibility

We develop a model that endogenizes dynamic financing, investment, and cash retention/payout policies in order to analyze the effect of financial flexibility on firm value. We show that the value of financing flexibility depends on the costs of external financing, the level of corporate and personal tax rates that determine the effective cost of holding cash, the firm's growth potential and maturity, and the reversibility of capital. Through simulations, we demonstrate that firms facing financing frictions should simultaneously borrow and lend, and we examine the nature of dynamic debt and liquidity policies and the value associated with corporate liquidity.     

Did children's education matter? Family migration as a mechanism of human capital investment: evidence from nineteenth‐century Bohemia

This article analyses the rural–urban migration of families in the Bohemian region of Pilsen in 1900. Using a new 1,300‐family dataset from the 1900 population census, the role of children's education in rural–urban migration is examined. The findings indicate that families migrated to the city such that the educational attainment of their children would be maximized, and that there is a positive correlation between family migration and children being apprentices in urban areas. The results suggest that rural–urban migration was powered not only by the exploitation of rural–urban wage gaps but also by aspirations to engage in human capital investment.
