Venture capitalists provide risk capital and valuable monitoring services that are essential for the success of upstart companies. The financial sector’s expertise in monitoring investment proposals may increase with the accumulated experience in funding such projects. In the other direction,...

We test under what circumstances boards discipline managers and whether such interventions improve performance. We exploit exogenous variation due to the staggered adoption of corporate governance laws in formerly Communist countries coupled with detailed ‘hard’ information about the...

In our model multiple innovators compete against each other by submitting investment proposals to an investor. The investor chooses the least expensive proposal and when to invest in it. Innovators have to provide costly effort and they learn privately the cost of investing. Multiple efforts...

Policy makers typically interpret positive relations between venture capital investments and innovations as an evidence that venture capital investments stimulate innovation ('VC-first hypothesis'). This interpretation is, however, one-sided because there may be a reverse causality that...

For the sample period of 1965-1992, Kortum and Lerner (2000) find that venture capital (VC) investments have a positive impact on patent count at industry level, and this impact is larger than that of R&D expenditures. We confirm that this positive impact continued to be present and became even...

We measure the extent to which skilled immigrants increase innovation in the United States by exploring individual patenting behavior as well as state-level determinants of patenting. The 2003 National Survey of College Graduates shows that immigrants patent at double the native rate, and that...

This paper studies the effect of top tax rates on inventors' mobility since 1977. We put special emphasis on "superstar" inventors, those with the most and most valuable patents. We use panel data on inventors from the United States and European Patent Offices to track inventors' locations over...

How can we explain the success of cooperative networks of firms that share innovations, such as Silicon Valley or the Open Source community? This Paper shows that if innovations are cumulative, making an invention publicly available to a network of firms may be valuable if the firm expects to...

In the 'Knightian' theory of entrepreneurship, entrepreneurs provide insurance to workers by paying fixed wages and bear all the risk of production. This paper endogenizes entrepreneurial risk by allowing for optimal insurance contracts as well as the occupational self-selection. Moral hazard...

Using panel data of 19 developed economies in the period 1985-2000, we show that share issue privatization (SIP) strongly affects a fundamental aspect of financial development: market liquidity. First, we identify the channels through which a sustained SIP program boosts the liquidity of the...
