After some decades of relative oblivion, the interest in the optimality properties of monopolistic competition has recently re-emerged due to the availability of an appropriate and parsimonious framework to deal with firm heterogeneity. Within this framework we show that non-separable utility,...

Classical theory of international trade has long advocated trade liberalization and open borders. However, this process is not necessarily beneficial to all countries involved. This paper focuses on two modeled economies that initially share the same technology and per-capita income, but differ...
