Gender Differences in Experimental Wage Negotiations

We examine behavioral gender differences and gender pairing effects in a laboratory experiment with face-to-face alternating-offers wage bargaining. Our results suggest that male players are able to obtain better bargaining outcomes than female players. Male employees get higher wages than female employees. Male employers pay lower wages to female employees than female employers pay to male employees. Moreover, we find gender differences in the first offers of the bargaining game.

Gender differences in trust and reciprocity: evidence from a large-scale experiment with heterogeneous subjects

This article examines gender differences in an experimental trust game. Recent studies have shown that men trust more and that women are more reciprocal in laboratory experiments. Participants in these studies, however, are typically university students who may not be representative of the entire population. In this study, we use data from a large-scale experiment with heterogeneous subjects who are representative of the German population. We find that men exhibit not only more trusting behaviour, but also more reciprocating behaviour than women. Moreover, our results are indicative of age-dependent gender differences. For men, we find an inverse U-shaped relationship between age, on the one hand, and both trust and reciprocity, on the other; however, we do not find age effects for women.

Spillover Effects of Minimum Wagesunder Union Wage Bargaining

Empirical and experimental research suggests that minimum wages cause spillovers to wages higher up in the wage distribution, i.e., they may even raise wages that were already above the new minimum wage. In this paper, we analyze how these findings can be explained by theoretical wage bargaining models between unions and firms. While the Nash bargaining solution is unaffected by minimum wages below initially bargained wages, we show that such minimum wages can drive up wages --- and be harmful to employment --- when bargaining follows the Kalai---Smorodinsky solution.

Welfare Effects of Local Versus Central Wage Bargaining

The paper analyses the welfare effects of union bargaining (de)centralization in a dual labour market with a unionized and a competitive sector. We show that social welfare depends on both the structure of the unions objective function and the elasticities of labour demand in both sectors. The welfare-maximizing employment allocation can be obtained under a high degree of centralization if the union maximizes the total wage-bill. Otherwise, if the union is rent maximizing, welfare is higher under local bargaining. However, in that case neither central nor local wage setting yields the social optimum.
