Does International Outsourcing Really Lower Workers’ Income?

We analyze the impact of international outsourcing on income, if the domestic labor market is imperfect, i.e. there is a bilateral bargaining between a firm and a labor union. In our analysis we distinguish between the cases where the parties negotiate over the wage only and where they negotiate over both wage and profit sharing. We find in the first case that outsourcing has an ambiguous effect on the workers’ income, while it increases the workers’ income in the second case. For the optimal amount of international outsourcing, we find that, depending on the wage effect of outsourcing, in a pure wage bargaining system it can be higher or lower than the level where domestic and foreign marginal labor costs are the same. In contrast, in a wage and profit share bargaining system, the amount of outsourcing lies below this level .
