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

We develop a general equilibrium model with heterogeneous firms à la Melitz (2003), where both the government and firms can invest into R&D to improve the country’s technological potential. A higher technological potential raises the average productivity of firms, thus implying lower consumer...

We develop a general equilibrium model of international trade with heterogeneous firms that accounts for productivity spillovers transmitted by foreign exporters. Everything else equal, stronger spillovers increase welfare. We embed the model framework into a trade policy scenario where...

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...

We provide an axiomatic framework for exchange markets with a willingnessto- 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 develop a two-sector general equilibrium model with monopolistic competition featuring nonhomothetic production and a variable demand elasticity for the manufactured goods. An increase in the relative price of manufacturing varieties can lead to a decline in total industrial output in our...
