We study how the interaction between economic openness and competitive selection affects the effectiveness of employment (and entry) subsidisation. Within a two-country heterogeneous-firms model with endogenous labour supply, we find that optimal employment subsidies are always positive even...

We analyse the implications of unions (efficient bargaining) for multiplicity of stationary states and welfare, local indeterminacy, bifurcations and endogenous fluctuations (deterministic and stochastic). We use an overlapping generations model with external increasing returns to scale, where...

This paper addresses the role of mobility costs in shaping the effects of trade integration on wage inequality and welfare. We present a three-factor, two-sector model in which the production technology exhibits capital-skill complementarity and the cost of moving across sectors differs between...
