Status considerations with respect to consumption give rise to negative externalities because individuals do not take into account that their decisions affect the relative consumption position of others. Further, status concerns create incentives for excessive labour supply in competitive...

If input markets are competitive and output per firm declines with the number of firms (business stealing effect), there will be excessive entry into a Cournot oligopoly for a homogeneous commodity. However, input markets are often imperfectly competitive and the price of labor is determined by...

Do trade unions benefit from economic crises by attracting new members among workers concerned about job security? To address this question, we provide a comprehensive empirical investigation based on panel data from Germany, where workers individually decide on their membership. We analyse...

The effects of trade union membership on wages and job satisfaction have been studied extensively. Arguably, life satisfaction serves as a more comprehensive measure of the benefits of union membership and warrants closer examination. Using all relevant waves from the German Socio-Economic Panel...

Trade unions are typically able to convert their industrial power into political power. We show that, depending on the parameter constellation, stronger trade unions may be welfare-improving in terms of an increase in aggregate employment and output, if they successfully lobby for lower trade...

We analyze the effects of unionization on the decision of a firm to either produce at home or abroad. We consider a model in which home and foreign workers are perfect substitutes and firms have an informational advantage concerning their productivity. The union offers wage-employment contracts...

A large number of articles have analysed 'the one constant' in the economic effects of trade unions, namely that union bargaining reduces employment growth by two to four percentage points per year. Evidence is, however, mostly related to Anglo-Saxon countries. We investigate whether a different...

What are the effects of firm- and sector-level trade unions on unemployment and aggregate output if individuals have rent-sharing motives? To answer this question, we extend a Melitz-type model to unionized labor markets. Because individual rent-sharing motives are only taken into account and...

Empirical evidence suggests that high-productivity firms face stronger trade unions than low-productivity firms. Then a policy that puts all unions into a better bargaining position is no longer neutral for firm selection as in models with a uniform bargaining strength across firms. Using a...

How does an increase in unionization costs, i.e. costs which arise when workers are organized by a union, affect the productivity distribution of active firms, wage inequality and welfare? In this paper, we build a model with costly, endogenous unionization, heterogeneous firms as well as free...
