- We show how the type of alcohol consumed is related to the type of entrepreneurship present for economies in Europe. We differentiate between beer-, wine-, and spirit-drinking countries and distinguish between productive, unproductive, and destructive entrepreneurship. The underlying links do not emerge from drinking per se but rather the drinking habits and taste for beverage types capture deep cultural features and cultural similarities amongst the countries. Societies that prefer to drink beer are closer to each other culturally than those which prefer drinking wine or spirits. Therefore, the taste for alcohol type is merely an instrument in explaining cultural and institutional differences across entrepreneurship. Broadly speaking, beer-drinking countries are characterized by higher shares of productive entrepreneurship, wine-drinking countries with unproductive entrepreneurship, and spirit-drinking countries with destructive entrepreneurship. We discuss mechanisms in which the results are found and highlight a new research agenda, emphasizing the potential role of epigenetics.

- In this paper we suggest that the spillover of knowledge may not occur automatically as typically assumed in models of endogenous growth. Rather, a mechanism is required to serve as a conduit for the spillover and commercialization of knowledge from the source creating it, to the firms actually commercializing the new ideas. In this paper, entrepreneurship is identified as one such mechanism facilitating the spillover of knowledge. Using a panel of entrepreneurship data from 18 countries, we provide empirical evidence that, in addition to measures of Research & Development and human capital, entrepreneurial activity also serves to promote economic growth.

Philippe Aghion : recipient of the 2016 Global Award for Entrepreneurship Research
- 2017

Tidskriftsartikel (refereegranskat)abstract
- Professor Philippe Aghion is the 2016 recipient of the Global Award for Entrepreneurship Research, consisting of 100,000 Euros and a statuette designed by the internationally renowned Swedish sculptor Carl Milles. He is one of the most influential researchers worldwide in economics in the last couple of decades. His research has advanced our understanding of the relationship between firm-level innovation, entry and exit on the one hand, and productivity and growth on the other. Aghion has thus accomplished to bridge theoretical macroeconomic growth models with a more complete and consistent microeconomic setting. He is one of the founding fathers of the pioneering and original contribution referred to as Schumpeterian growth theory. Philippe Aghion has not only contributed with more sophisticated theoretical models, but also provided empirical evidence regarding the importance of entrepreneurial endeavours for societal prosperity, thereby initiating a more nuanced policy discussion concerning the interdependencies between entrepreneurship, competition, wealth and growth.

The knowledge spillover theory of entrepreneurship
- 2009

- Contemporary theories of entrepreneurship generally focus on the recognition of opportunities and the decision to exploit them. Although the entrepreneurship literature treats opportunities as exogenous, the prevailing theory of economic growth suggests they are endogenous. This paper advances the microeconomic foundations of endogenous growth theory by developing a knowledge spillover theory of entrepreneurship. Knowledge created endogenously results in knowledge spillovers, which allow entrepreneurs to identify and exploit opportunities.

The missing link : knowledge diffusion and entrepreneurship in endogenous growth

- The intellectual breakthrough contributed by the new growth theory was the recognition that investments in knowledge and human capital endogenously generate economic growth through the spillover of knowledge. However, endogenous growth theory does not explain how or why spillovers occur. This paper presents a model that shows how growth depends on knowledge accumulation and its diffusion through both incumbents and entrepreneurial activities. We claim that entrepreneurs are one missing link in converting knowledge into economically relevant knowledge. Implementing different regression techniques for the Organisation for Economic Co-operation and Development (OECD) countries during 1981 to 2002 provides surprisingly robust evidence that primarily entrepreneurs contributed to growth and that the importance of entrepreneurs increased in the 1990s. A Granger test confirms that causality goes in the direction from entrepreneurs to growth. The results indicate that policies facilitating entrepreneurship are an important tool to enhance knowledge diffusion and promote economic growth.

- This article explores the relationship between knowledge creation, entrepreneurship, and economic growth in the United States over the last 150 years. Distinguishing between general knowledge and economically useful knowledge, we examine the changes over time in the locus and content of new knowledge creation: the role of universities, particularly engineering schools and land-grant universities, industrial laboratories, and corporate research and development (R&D) laboratories prior to World War II. The practical orientation of US academic R&D and the close research interaction between academia and industry are noted. We study the unprecedented increase in R&D spending in the United States during and after World War II and how it was converted into economic activity via incumbent firms in the early postwar period and increasingly via new ventures in the last few decades.

Evidence for widespread cryptic sexual generations in apparently purely asexual Andricus gallwasps
- 2008

- Oak gallwasps (Hymenoptera, Cynipidae, Cynipini) are one of seven major animal taxa that commonly reproduce by cyclical parthenogenesis (CP). A major question in research on CP taxa is the frequency with which lineages lose their sexual generations, and diversify as purely asexual radiations. Most oak gallwasp species are only known from an asexual generation, and secondary loss of sex has been conclusively demonstrated in several species, particularly members of the holarctic genus Andricus. This raises the possibility of widespread secondary loss of sex in the Cynipini, and of diversification within purely parthenogenetic lineages. We use two approaches based on analyses of allele frequency data to test for cryptic sexual generations in eight apparently asexual European species distributed through a major western palaearctic lineage of the gallwasp genus Andricus. All species showing adequate levels of polymorphism (7/8) showed signatures of sex compatible with cyclical parthenogenesis. We also use DNA sequence data to test the hypothesis that ignorance of these sexual generations (despite extensive study on this group) results from failure to discriminate among known but morphologically indistinguishable sexual generations. This hypothesis is supported: 35 sequences attributed by leading cynipid taxonomists to a single sexual adult morphospecies, Andricus burgundus, were found to represent the sexual generations of at least six Andricus species. We confirm cryptic sexual generations in a total of 11 Andricus species, suggesting that secondary loss of sex is rare in Andricus.
