Abstract: | Abstract: Using German establishment-level data, this paper analyses whether wages respond to firm-specific profitability conditions. Particular emphasis is given to the question of whether the extent of rent-sharing varies with collective bargaining coverage. In this context, two conflicting hypotheses are tested. The first one asserts that unions exploit their bargaining power at the firm-level and appropriate a larger share of rents than the bargaining parties in uncovered firms. The second one states that unions favour a compressed intra-industry wage structure and suppress the responsiveness of wages to firm-specific profitability conditions.\ The empirical analysis provides strong support for the second hypothesis. While pooled OLS estimates yield positive estimates of the rent-sharing coefficient in covered establishments, dynamic panel data estimates accounting for unobserved heterogeneity and the endogeneity of rents point to a rent-sharing coefficient of zero |
