Home sweet home: Entrepreneurs’ location choices and the performance of their ventures

Michael S. Dahl and Olav Sorenson

Entrepreneurs, even more than employees, tend to locate in regions in which they have deep roots. Here, we examine the performance implications of these choices. Whereas one might expect entrepreneurs with deep roots to perform better because of their richer endowments of social capital, they might also perform worse if their location choices rather reflect a preference for spending time with family and friends. We examine this question using comprehensive data on the Danish population. Entrepreneurs’ ventures perform better – survive longer and generate greater cash flows and cumulative profits – when they locate in regions in which they have deep roots (“home” regions). This effect appears substantial, similar in magnitude to the value of having prior experience in the industry entered (i.e. specific human capital).

The ratings game: Asymmetry in classification

David M. Waguespack and Olav Sorenson

Categorization processes are generally treated as consistent mappings of the underlying characteristics that they group. Yet, in many cases, the identities of actors influence these processes. When identity matters, high status actors often obtain more favorable classifications. We examine these processes in the context of the Motion Picture Association of America’s parental guidance classifications of movies (G, PG, R, NC-17). We find that, conditional on a given level of content, films distributed by MPAA members, and those that involve more central producers and directors, receive more lenient classifications than those carried by independent distributors and involving more peripheral personnel. Conversely, and again conditional on content, films involving directors with a history of producing R rated features receive more restrictive ratings. We discuss the mechanisms that might account for these effects. Regardless of the mechanism, however, since ratings influence revenue and consequently profitability, the movie certification system in the United States places independent distributors and peripheral individuals at a disadvantage relative to their larger and more central rivals.

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

Sampsa Samila and Olav Sorenson

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.

The social attachment to place

Michael S. Dahl and Olav Sorenson

Many theories either implicitly or explicitly assume that individuals readily move to locations that improve their financial well being. Other forces, however, offset these tendencies; for example, people often wish to remain close to family and friends. We introduce a methodology for determining how individuals weight these countervailing forces, and estimate how both financial incentives and social factors influence the probability of geographic mobility in the Danish population from 2002 to 2003. Our results suggest that individuals respond to opportunities for higher pay elsewhere, but that their sensitivity to this factor pales in comparison to their preferences for living near family and friends.

Venture capital as a catalyst to commercialization

Sampsa Samila and Olav Sorenson

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.

The migration of technical workers

Michael S. Dahl and Olav Sorenson

Using panel data on the Danish population, we estimated the revealed preferences of scientists and engineers for the places in which they choose to work. Our results indicate that these technical workers exhibit substantial sensitivity to differences in wages but that they have even stronger preferences for living close to family and friends. The magnitude of these preferences, moreover, suggests that the greater geographic mobility of scientists and engineers, relative to the population as a whole, stems from more pronounced variation across regions in the wages that they can expect. These results remain robust to estimation on a sample of individuals who must select new places of work for reasons unrelated to their preferences—those who had been employed at establishments that discontinued operations.

The embedded entrepreneur

Michael S. Dahl and Olav Sorenson

Using comprehensive data on the Danish population, this paper examines the determinants of entrepreneurs’ choices of where to locate their newventures. Our findings suggest that entrepreneurs place much more emphasis on being close to family and friends than on regional characteristics that might influence the performance of their ventures when deciding where to locate those businesses. Two factors could explain our findings: On the one hand, entrepreneurs may simply value proximity to family and friends. On the other hand, these relationships may help them to assemble the assets and to recruit the personnel that they need to succeed in their ventures. Our results suggest that the former plays the greater role in entrepreneurs’ location choices.

The case for formal theory

Ron Adner, Laszlo Polos, Michael D. Ryall, and Olav Sorenson

This special topic forum contains seven papers that illustrate many of the ways in which management researchers can use formal tools–mathematical methods, simulation, and formal logic–to develop management research. Here we offer an overview of these methods and their advantages as tools for research.

The mobilization of scarce resources

Bjørn Løvås and Olav Sorenson

We examine how the ability of one actor to gain access to resources controlled by another depends on two factors: (i) the number of mutual acquaintances connecting the prospective lender and borrower and (ii) the scarcity of the resources in question. We argue that the incentives to renege on an agreement grow as the resources being traded become increasingly scarce. Mutual acquaintances, however, dampen these incentives, and therefore become more important to facilitating exchange as demand for the good of interest rises. Our analysis of qualitative and quantitative evidence from a study of senior partners at an international consultancy supports these propositions.
