In this paper, we analyse the effects of a unilateral change in an emissions tax in a model of international trade with heterogeneous firms.

Job polarisation is the result of a reallocation of labour across firms that differ in productivity and pay wages that are positively linked to their profits by...

We set up a trade model with heterogeneous firms and a worker population that is heterogeneous in two dimensions: workers are either skilled or unskilled, and within each skill category there is a continuum of abilities. Workers with high abilities, both skilled and unskilled, are matched to...
