Despite their presence in modern entrepreneurship theories, empirical investigations of opportunity types are scarce. Our contribution is twofold. First, we developed a measure to document the extent in which opportunities are Schumpeterian or Kirznerian. Both types of opportunities are supposed to be the anchors of a bipolar measure. Its items capture five dimensions that, as proposed in Scott Shane’s A general theory of entrepreneurship (2003), distinguish between Schumpeterian and Kirznerian opportunities: disequilibrating/equilibrating, new information/no new information involved, very innovative/less innovative, rare/common, and creation/discovery. Second, we analyzed individual characteristics associated with both opportunity types, exploring Shane’s idea of the individual-opportunity nexus.
