The shape and structure of entrepreneurial and innovative places

Geoffrey Borchhardt and Olav Sorenson

Interactions primarily occur between those living and working in close proximity to one another. This essay explores some consequences of that fact for places. It offers three principle propositions: (1) Compact buildings, neighborhoods, and cities, and denser places, should promote higher rates of entrepreneurship, innovation, and economic growth because they reduce the costs of interaction. (2) More integrated places should also promote entrepreneurship and innovation because the average person in those places interacts with a more diverse set of others. (3) In more segregated and unevenly distributed places, people diverge more, as a function of where within the place they live and work, in their propensities to innovate and to found firms.

Entrepreneurship and gentrification

Luisa Gagliardi and Olav Sorenson

How do high-growth startups influence the neighborhoods in which they locate? Using data from the greater London area, we show a positive relationship between entrepreneurship and the subsequent growth of residential real estate prices in a neighborhood. These effects appear concentrated in places that had been cheaper prior to the entry of the entrepreneurs. The demographic composition of these communities also changes in a classic pattern of gentrification, with older, less educated residents being replaced by younger, more educated ones.

Jockeys, horses or teams? The selection of startups by venture capitalists

Tekin Esen, Michael S. Dahl, and Olav Sorenson

How do venture capitalists select startups? Most research to date has focused on the attributes of either the founders (the jockey) or the business idea (the horse) as the determinants of selection. Connecting information from VentureXpert to the Danish registry data allows us to extend this analysis to include information on all employees of startups (the team). To assess the importance of these factors to access to venture capital, our analysis compares startups that received funding to other startups founded at the same time and in the same industry. Consistent with the jockey hypothesis and prior research, we find that firms with more and better educated founders have a higher probability of receiving venture capital. However, high-quality employees appear to matter even more than founders to the probability of being funded.

Do startup employees earn more in the long run?

Olav Sorenson, Michael S. Dahl, Rodrigo Canales, and M. Diane Burton

Evaluating the attractiveness of startup employment requires an understanding of both what startups pay and the implications of these jobs for earnings trajectories. Analyzing Danish registry data, we find that employees hired by startups earn roughly 17% less over the next ten years than those hired by large, established firms. About half of this earnings differential stems from sorting—from the fact that startup employees have less human capital. Long-term earnings also vary depending on when individuals are hired. While the earliest employees of startups suffer an earnings penalty, those hired by already-successful startups earn a small premium. Two factors appear to account for the earnings penalties for the early employees: Startups fail at high rates, creating costly spells of unemployment for their (former) employees. Job mobility patterns also diverge: After being employed by a small startup, individuals rarely return to the large employers that pay more.

Do startups pay less?

M. Diane Burton, Michael S. Dahl, and Olav Sorenson

We analyzed Danish registry data from 1991 to 2006 to determine how firm age and size influence wages. Unadjusted statistics suggest that smaller firms paid less than larger ones and that firm age had little or no bearing on wages. After adjusting for differences in the characteristics of employees hired by these firms, however, we observed both firm age and firm size effects. We found that larger firms paid more than smaller firms for observationally-equivalent individuals but, contrary to conventional wisdom, that younger firms paid more than older firms. The size effect, however, dominates the age effect. Thus, while the typical startup – being both young and small – paid less than a more established employer, the largest ones paid a wage premium.

Social networks and the geography of entrepreneurship

Print version of Prize Lecture for the Global Award for Entrepreneurship Research, 2018

Olav Sorenson

Social relationships play at least three important roles in entrepreneurship. They help to determine who sees entrepreneurship as an available and desirable career path. Entrepreneurs use their contacts to raise funds for and to recruit employees and partners to their ventures. Social relationships also influence where and when entrepreneurs want to spend their leisure time. Because of these factors, entrepreneurs tend to found their firms in the places that they live (and in the industries in which they have been employed). That, in turn, implies that industries will tend to become and remain concentrated in a small number of places, even when firms do not benefit from this clustering.

Innovation policy in a networked world

Olav Sorenson

Social relationships channel information, influence, and access to scarce resources. As a consequence, social networks—-the patterns of these relationships across the members of a community—-influence who comes up with important innovations, whether and how rapidly those innovations get adopted, and who has the ability to commercialize them. They therefore also affect the overall rate at which innovation occurs in the economy. This paper provides an introduction to and review of the research on social networks most relevant to innovation, with a particular focus on the earliest stages of the innovation process. It then discusses the likely consequences of a variety of policy interventions that could either reduce the importance of social relationships to innovation or alter the patterns of relationships in ways that might promote innovation.

Legitimacy and the benefits of firm formalization

Valentina Assenova and Olav Sorenson

Entrepreneurs in many emerging economies start their firm informally, without registering with the state. We examine how informality at the time of founding affected the growth and performance of 12,146 firms in 18 countries across sub-Saharan Africa. Our findings indicate that entrepreneurs who registered their firms at founding enjoyed greater success, in terms of sales and employment. But these benefits varied widely across countries. Countries in which people perceive the government as being less corrupt, those in which they have greater trust in the courts, and those with lower levels of ethnic conflict had larger performance benefits associated with being formal. The benefits of firm formalization therefore appear to depend on the socio-political legitimacy of the state.

Regional ecologies of entrepreneurship

Olav Sorenson

Why do some regions produce more entrepreneurs than others? An ecological lens provides insight into this question: The demography of organizations in a region – particularly the proportion of small and young em- ployers – shapes many aspects of the environment for would-be entrepreneurs: (i) beliefs about the desirability of founding a firm, (ii) opportunities to learn about entrepreneurship and to build the abilities needed to succeed, and (iii) the ease of acquiring critical resources. Births of new industries and the demise of mature ones can therefore catalyze rapid changes in the rates of entrepreneurship that become self-reinforcing.

Community and capital in entrepreneurship and economic growth

Sampsa Samila and Olav Sorenson

We argue that social and financial capital have a complementary relationship in fostering innovation, entrepreneurship and economic growth. Using panel data on metropolitan areas in the United States, from 1993 to 2002, our analyses reveal that social integration – in the microgeography of residential patterns – moderates the effect of venture capital, with more integrated regions benefitting more from expansions in the supply of financial capital. Our results remain robust to estimation with an instrumental variable to address potential endogeneity in the geography of venture capital. We also find some evidence for a similar effect from business associations. Our findings support the idea that social structure may contribute importantly to regional economic differences.
