The biotechnology industry has been an engine of innovation for the U.S. healthcare system and, more generally, the U.S. economy. It is by far the most research intensive industry in the U.S. In our analyses in the current paper, for example, we find that, over the past 25 years, average R&D...

We model how lobbying by interest groups affects the level of investor protection. In our model, insiders in existing public companies, institutional investors (financial intermediaries), and entrepreneurs who plan to take companies public in the future, compete for influence over the...

We show that the development of the financial sector does not change monotonically over time. In particular, we find that by most measures, countries were more financially developed in 1913 than in 1980 and only recently have they surpassed their 1913 levels. This pattern is inconsistent with...

We observe less efficient capital allocation in countries whose banking systems are more thoroughly controlled by tycoons or families. The magnitude of this effect is similar to that of state control over banking. Unlike state control, tycoon or family control also correlates with slower...

This paper examines the relationship between innovation and firms' dependence on external capital by analyzing the innovation activities of privately-held and publicly-traded firms. We find that public firms in external finance dependent industries generate patents of higher quantity, quality,...

Financing terms and investment decisions are jointly determined. This interdependence links firms' asset and liability sides and can lead to short-termism in investment. In our model, financing frictions increase with the investment horizon, such that financing for long-term projects is...

Equity overvaluation is thought to create the potential for managerial misbehavior, while monitoring and corporate governance curb misbehavior. We combine these two insights from the literatures on misvaluation and governance to ask 'when does governance matter?' Examining firms with standard...

An influential thesis, dubbed "Doing well by doing good," argues that corporate social responsibility is profitable. But heterogeneity in firm financial constraints can induce a spurious correlation between profits and goodness even if the motives for goodness are non-profit in nature. We use...

This paper investigates whether individual venture capitalists have repeatable investment skill and to what extent their skill is impacted by the VC firm where they work. We examine a unique dataset that tracks the performance of individual venture capitalists' investments across time and as...

We consider IPO firms from 1970 to 2001 and examine the evolution of their insider ownership over time to understand better why and how U.S. firms that become widely held do so. In our sample, a majority of firms has insider ownership below 20% after ten years. We find that a firm's stock market...
