Research on entrepreneurship has received an increased amount of interest in recent years, with self-employment being used as the most common proxy for “entrepreneurship” in empirical studies. However, there are various ways of defining self-employment, making it a somewhat dubious proxy....

This paper analyzes how institutional differences affect university entrepreneurship. We focus on ownership of faculty inventions, and compare two institutional regimes; the US and Sweden. In the US, the Bayh Dole Act gives universities the right to own inventions from publicly funded research,...

Existing empirical evidence suggests that entrepreneurs are optimists, a finding researchers often interpret as evidence of a behavioral bias in entrepreneurial decision-making. We revisit this claim by analyzing an unusually large survey dataset (180,814 responses) that allows us to create a...

The paper estimates the causal effect of trade liberalisation on aggregate productivity through mechanisms related to firm selection. The construction of a bridge in 2000 across the Öresund Strait linking Copenhagen with Malmö, Swedens third largest city, provided a natural experiment with...

Previous research indicates that exporting firms are willing to pay a premium to poach workers from other exporting firms if experience working for an internationally engaged firm reduces trade costs. Since international experience is less valuable to non-exporters, we would expect to see...

Relying on Forbes Magazine annual rankings for two decades, 1625 billionaires and their countries of birth and residence are identified, most of whom are self-made entrepreneurs. 13 percent of billionaires reside in a country other than that of their birth. Migration is linked to distance, to...

Many governments promote small businesses for the dual reasons of fostering 'breakthrough' innovations and employment growth. In this paper we study the effects of tax and subsidy policies on entrepreneurs' choice of riskiness of an innovation project and on their mode of commercializing the...

Existing studies of entrepreneurship focus on entrepreneurs whose individual contribution to wealth creation is typically trivial: self-employed persons. This paper investigates entrepreneurs whose individual contribution to wealth creation is enormous: billionaires. We explore the relationship...

We show that this implies that entrepreneurs will choose more risky projects than incumbents, aiming to reduce their high expected marginal commercialization cost. However, entrepreneurs may select too safe projects from a social...

Abstract: The overwhelming majority of self-employed individuals are not entrepreneurial in the Schumpeterian sense. In order to unmistakably identify Schumpeterian entrepreneurs we focus on self-made billionaires (in USD) on Forbes Magazine's list who became wealthy by founding new firms. In...
