Non-compete covenants: Incentives to innovate or impediments to growth

We find that the enforcement of non-compete clauses significantly impedes entrepreneurship and regional growth. Based on a panel of metropolitan areas in the United States from 1993 to 2002, our results indicate that, relative to regions in states that enforce non-compete covenants, an increase in the local supply of venture capital in states that restrict them has significantly stronger positive effects on (i) the number of patents, (ii) the number of firm starts, and (iii) employment. We address potential endogeneity issues in the supply of venture capital by using endowment returns as an instrumental variable. Our results point to a strong interaction between financial intermediation and the legal regime in promoting entrepreneurship and growth.

Venture capital, entrepreneurship, and economic growth

Sampsa Samila and Olav Sorenson

Using a panel of U.S. metropolitan areas from 1993 to 2002, we find that an increase in the local supply of venture capital (VC) positively affects (i) the number of firm starts, (ii) employment, and (iii) aggregate income. Our results remain robust to a wide variety of specifications, including ones that address potential endogeneity in the supply of venture capital. The magnitudes of the effects, moreover, imply that venture capital stimulates the creation of more firms than it directly funds. That result appears consistent with either of two mechanisms: One, would-be entrepreneurs that anticipate a future need for financing more likely start firms when the supply of capital expands. Two, companies funded by venture capital may transfer tacit knowledge to their employees thereby enabling spinoffs, and may encourage both their own employees and others to become entrepreneurs through demonstration effects.

Venture capital as a catalyst to commercialization

We find that public research funding and venture capital have a complementary relationship in fostering innovation and the creation of new firms. Based on a panel of metropolitan areas in the United States from 1993 to 2002, we find that the positive relationships between government research grants and the rates of patenting and firm formation in a region become more pronounced as the supply of venture capital in that region increases. Our results remain robust to estimation with an instrumental variable to address potential endogeneity in the provision of venture capital. Consistent with perspectives that emphasize the importance of an innovation ecosystem, our results therefore point to a strong interaction between private financial intermediation and public research funding in promoting entrepreneurship and growth.

Bringing the context back in: Settings and the search for syndicate partners in venture capital investing

August 7th, 2009 | Posted by admin in 2008 - (0 Comments)

Most existing theories of relationship formation imply that actors form highly cohesive ties that aggregate into homogenous clusters, but actual networks also include many “distant” ties between parties that vary on one or more social dimensions. To explain the formation of distant ties, we propose a theory of relationship formation based on the characteristics of “settings,” or the places and times in which actors meet. We posit that organizations form relations with distant partners when they participate in two types of settings: unusually faddish ones and those with limited risks to participants. In an empirical analysis of our thesis in the formation of syndicate relations between U.S. venture capital firms from 1985 to 2007, we find that the probability that geographically and industry distant ties will form between venture capital firms increases with several attributes of the target-company investment setting: (1) the recent popularity of investing in the target firm’s industry and home region, (2) the target company’s maturity, (3) the size of the investment syndicate, and (4) the density of relationships among the other members of the syndicate.

The geography of opportunity: Spatial heterogeneity in founding rates and the performance of biotechnology firms

August 7th, 2009 | Posted by admin in 2003 - (0 Comments)

Toby E. Stuart and Olav Sorenson

One of the most commonly observed features of the organization of markets is that similar business enterprises cluster in physical space. In this paper, we develop an explanation for firm co-location in high-technology industries that draws upon a relational account of new venture creation. We argue that industries cluster because entrepreneurs find it difficult to leverage the social ties necessary to mobilize essential resources when they reside far from those resources. Therefore, opportunities for high tech entrepreneurship mirror the distribution of critical resources. The same factors that enable high tech entrepreneurship, however, do not necessary promote firm performance. In the empirical analyses, we investigate the effects of geographic proximity to established biotechnology firms, sources of biotechnology expertise (highly-skilled labor), and venture capitalists on the location-specific founding rates and performance of biotechnology firms. The paper finds that the local conditions that promote new venture creation differ from those that maximize the performance of recently established companies.

Syndication networks and the spatial distribution of venture capital investments

August 7th, 2009 | Posted by admin in 2001 - (0 Comments)

Olav Sorenson and Toby E. Stuart

Sociological investigations of economic exchange reveal how institutions and social structures shape transaction patterns among economic actors. This article explores how interfirm networks in the U.S. venture capital (VC) market affect spatial patterns of exchange. Evidence suggests that information about potential investment opportunities generally circulates within geographic and industry spaces. In turn, the circumscribed flow of information within these spaces contributes to the geographic- and industry-localization of VC investments. Empirical analyses demonstrate that the social networks in the VC community—built up through the industry’s extensive use of syndicated investing—diffuse information across boundaries and therefore expand the spatial radius of exchange. Venture capitalists that build axial positions in the industry’s coinvestment network invest more frequently in spatially distant companies. Thus, variation in actors’ positioning within the structure of the market appears to differentiate market participants’ ability to overcome boundaries that otherwise would curtail exchange.
