This paper sets up a general oligopolistic equilibrium model with multi-product firms and union wage setting in a subset of industries. By claiming a wage premium, labor unions enforce a decline in firm scale and scope and thus dampen industrial output, with negative feedback effects on the...

This paper sets up a general oligopolistic equilibrium model with unionized labor markets. By accounting for productivity differences, the model features pro t and wage differentials across industries. We use this setting to study the impact of trade liberalization on employment, welfare, and...

We develop a framework for studying how differences in the level and/or dispersion of per-capita income affect trade structure and welfare in a two-country model. Thereby, we embed nonhomothetic preferences into a home-market model with two sectors of production and one input factor. We...

This paper looks inside the firm and investigates how trade alters the matching of worker-specific abilities and task-specific skill requirements. The outcome of this matching depends on how firms organize their recruitment process and how much they invest into the screening of applicants. In...

We set up a trade model with two countries, two sectors, and one production factor, which features a home-market effect due to the existence of trade costs. We consider search frictions and firm-level wage bargaining in the sector producing differentiated goods and a perfectly competitive labor...

This paper evaluates the effect of foreign takeover on wages of workers in German establishments, using rich linked employer-employee data from 2003 to 2014. To identify a causal effect of foreign takeover, we combine propensityscore matching with a difference-in-difference estimator. We find...

We merge firm-level data on ownership linkages with administrative data on German workers to analyze how the position in a business group hierarchy affects workers' wages. To acknowledge that ownership linkages are not onedirectional, we propose an index of hierarchical distance to the ultimate...
