This paper uses a model (consisting of a linear estimate of a demand curve, a linear quadratic cost curve and a logistic diffusion curve) and four types of imperfectly competitive behaviour — monopolistic intertemporal profit maximization, a dynamic Bertrand oligopoly, and a duopolistic...

We examine the effects of endogenous offshoring on cost-efficiency, wages and unemployment in a task- assignment model with skill heterogeneity. Exact conditions for the following insights are derived. The distributional effect of offshoring (high-) low-skill-intensive tasks is similar to...

This paper analyses the impact of the skill composition of migration flows on the host country's labour market in a specific-factors-two-sector model with heterogeneous labour (low, medium, and high skill) and price- and wage-setting behaviour. The low- and medium-skilled labour markets are...
