We develop a model of wage bargaining with private information in a duopoly. We investigate how product differentiation and market competition (Bertrand vs. Cournot competition) affect wages and strikes. If bargaining takes place at the industry-level, then both the wage outcome and the strike activity do not depend on the degree of product differentiation whatever the type of market competitio...

In “Capital-Skill Complementarity and Inequality: A Macroeconomic Analysis,” Krusell et al. (2000) analyzed the capital-skill complementarity hypothesis as an explanation for the behavior of the U.S. skill premium. This paper shows that their model’s fit and the values of the estimated parameters are very sensitive to the data used: Alternative measures of the capital series predict skill premi...

Using German linked employer-employee data, this paper investigates the impact of on-the-job training on wages. The applied estimation technique was fi rst introduced by Leuven and Oosterbeek (2008). The idea is to compare wages of employees who intended to participate in training but did not do so because of a random event with wages of training participants. The estimated wage returns are sta...

It is useful to measure classification complexity for understanding classification tasks, selecting feature subsets and learning algorithms. In this work, we review some current measures of classification complexity and propose two new coefficients: neighborhood dependency (ND) and neighborhood decision error (NDEM). ND reflects the ratio of boundary samples over the whole sample set; while NDE...
