In a framework of a unionised international Bertrand duopoly with differentiated products, this paper analyses national labour market interdependencies and the consequences of trade liberalisation for union wages. The analysis suggests that national wages are likely to be strategic complements...

Our study compares the efficiency of centralized and decentralized unemployment insurance programs in a state union. We use a model of two countries with collective bargaining for regional gross wages. The labor force and the firms are partially mobile across the member states of the state...
