We provide an axiomatic framework for exchange markets with a willingness- to-pay/willingness-to-accept discrepancy. First, we obtain a two parameter family of market invariants under price-scaling representing the excess demand. One of the parameters can be identified as endowment. The other is...

We study a general equilibrium model of international trade with heterogeneous firms, where countries can strategically invest in technology. The countries' motive is to improve firms' productivity, leading to a competitive advantage in international trade. We are interested in how trade...

We extend the Behrens et al. (2009) general equilibrium heterogeneous firms framework by horizontal foreign direct investment. The model features endogenously determined firm entrants, wages, productivity cutoff s, flexible price markups and allows for wage differentials across countries in...
