Collective Agreements, Wages, and Firms' Cohorts: Evidence from Central Europe

Using a large, matched employer-employee data set, the authors investigate the impact of company and industry collective bargaining agreements on wages in the Czech Republic, Hungary, and Poland (CE3). They also examine the changing characteristics of the union wage premium in different cohorts of establishments. Their results challenge the common idea of weak unions in the CE3 by revealing a union wage premium whose characteristics depend on the level at which collective bargaining occurs. They find that industry agreements increase wages for low-skilled workers, while company agreements increase medium- and high-skilled wages. Their second finding is that the union wage premium is unevenly distributed between cohorts, with substantial cross-country variation. Wage premiums are concentrated in the transitional cohorts in the Czech Republic and Poland and, to a lesser extent, in the pre-transitional cohort in Hungary.

Commodity Taxation and Regulatory Competition

This paper studies competition in regulation and commodity taxation between trading countries. We present a general equilibrium model in which destination based consumption taxes finance public goods, while regulation of entry determines the number of firms in the markets. We find (i) no strategic interaction in commodity taxes; (ii) regulation leads to lower commodity tax rates if demand for public goods is more sensitive to income than demand for private goods and (iii) regulation policy is a strategically complement instrument if consumers do not over value product diversity. In the empirical part of the paper, we test our predictions using panel data for 21 OECD countries over the period 1990-2008.
