This work aims to investigate if the conventional wisdom, that a decrease in the degree of product differentiation always reduces firms’ profits, remains true in a differentiated duopoly model with decentralized, or firm-specific, monopoly unions. It is shown that, provided that unions are...

This paper compares Cournot and Bertrand equilibria in a differentiated duopoly (with imperfect substitutes), total wage bill maximizing unions and labour decreasing returns. It is shown that the standard result, that equilibrium profits are always higher under Cournot, may be reversed even for...

Can a merger from duopoly to monopoly be detrimental for profits? This paper deals with this issue by focusing on the interaction between decreasing returns to labour (which imply firms’ convex production costs) and centralised unionisation in a differentiated duopoly model. It is pointed out...

In this paper, we aim at investigating if the conventional wisdom, that an increase of competition linked to a decrease in the degree of product differentiation always reduces firms’ profits, remains true in a unionized duopoly model with labour decreasing returns. In this context, mixed...

Despite its lack of attractiveness to other countries, the German system of quasi-parity codetermination at company level has held up remarkably well. We recount the theoretical arguments for and against codetermination and survey the empirical evidence on the effects of the institution, tracing...

This paper provides the first comprehensive examination of the effect of German works councils on wages, using matched employer-employee data from the German LIAB for 2001. We find that works councils are associated with higher earnings: the wage premium is around 11 percent, and is higher under...

This paper provides a comprehensive examination of the effect of German works councils on wages, using matched employer-employee data from the German LIAB for 2001. In general, we find that works councils are associated with higher earnings, even after accounting for worker and establishment...
