Determinants of entrepreneurship using fuzzy set methods: Europe vs. non-Europe

ABSTRACT This article uses fuzzy set qualitative methods, with Global Entrepreneurship Monitor 2014 data, to show differences in the entrepreneurial determinants between European developed countries and non-European developing countries. We first estimate baseline regression models and then develop fuzzy set qualitative comparative analysis to study the necessary and sufficient conditions of entrepreneurial activity. Results indicate that, while in Europe, the key determinants are education and technological equity; individuals in developing and nondeveloped countries tend to be, or become, entrepreneurs independently of the macroeconomic background.

Spatial distribution of US employment in an urban efficiency wage setting

We analyze whether efficiency wages operate in urban labor markets, within the framework proposed by Ross and Zenou, in which shirking at work and leisure are assumed to be substitutes. We use unique data from the American Time Use Survey (ATUS) that allow us to analyze the relationships between leisure, shirking, commuting, employment, and earnings. We confirm that shirking and leisure are substitutes, and present an estimate of this relationship, representing the only empirical test of the relationship between a workers time endowment and shirking at work. Our findings point to the existence of efficiency wages in labor markets.
