This paper studies the causal effects of graduating from university with an honors degree on subsequent earnings. While a rich body of literature has focused on estimating returns to human capital, few studies have analyzed returns at the very top of the education distribution. We highlight the...

This paper focuses on gender differences in the role played by locus of control within a model that predicts outcomes for men and women at two opposite poles of the labour market: high level managerial / leadership positions and unemployment. Based on data from the German Socio-Economic Panel,...

This paper analyzes research efficiency at the industry level in manufacturing for 13 European member and four nonmember countries during 2000 and 2004. A unique dataset was compiled that matches patent applications at the European Patent Office (EPO) to industry-specific R&D inputs from EU...
