Preferences are fundamental building blocks in all models of economic and political behavior. We study a new sample of comprehensively genotyped subjects with data on economic and political preferences and educational attainment. We use dense single nucleotide polymorphism (SNP) data to estimate...

A genome-wide association study (GWAS) of educational attainment was conducted in a discovery sample of 101,069 individuals and a replication sample of 25,490. Three independent single-nucleotide polymorphisms (SNPs) are genome-wide significant (rs9320913, rs11584700, rs4851266), and all three...

We find new empirical regularities in the business cycle in a cross-country panel of 22 OECD countries for the period 1972 to 2007; entrepreneurship Granger-causes the cycles of the world economy. Furthermore, the entrepreneurial cycle is positively affected by the national unemployment cycle. We...

Die Internetnutzung in Deutschland hat in den letzten acht Jahren einen rasanten Anstieg erlebt. Während es im Frühjahr 1995 in Deutschland gerade einmal 250 000 Internetnutzer gab, waren es im Mai 2003 bereits knapp 39 Millionen. Dies bedeutet, dass aktuell etwa 47 % der gesamten Bevölkerung...

The article argues that IT continues to have strategic relevance for companies because it en-ables innovation. A conceptual link between the adoption of IT and innovation is established. This conceptual link allows a market-based, economic explanation for variations in IT payoffs among firms:...

Many firms fail shortly after inception. Yet individuals continue starting businesses. Prewar economists such as Keynes invoked animal spirits and stressed psychological factors in their explanations of economic behavior. Using a large sample obtained from surveys conducted in 18 countries, we...

We use a sample of 18 countries to study what variables have a significant impact on an individual's decision to start a new business and classification and regression trees for an accurate interpretation of the data. Our results support existing literature suggesting the existence of strong...

Using a sample obtained from a survey conducted in the United States during summer 2002, we study the variables related to observed differences in the rate of entrepreneurial involvement between black and white Americans. We find strong evidence that differences in subjective and often biased...
