Main Research Themes

Current: What is the role of intermediaries in international trade? What contracts and vertical restraints do manufacturers wish to impose on retailers or wholesalers when trade becomes freer? Can parallel imports help manufacturers when they must sell their products through intermediaries? Do retailers affect trade liberalization and welfare?

Past: Is collusion easier when markets integrate? Do firms react to freer trade by changing their product attributes? Does exchange pass-through depend on strategic interactions among foreign sellers?

Should a country free up international labor mobility? Should it do so when workers are differentiated by skills? Do incentives to migrate differ depending on skills? Do temporary foreign workers affect domestic labor market adjustment mechanisms?

Why have countries replaced tariffs by quotas and then quotas by antidumping measures? Who benefit from antidumping? Why do developing countries often have an import tariff and an export subsidy in the same sector?

Using applied general equilibrium framework, these articles look at three different cases: (i) the relationship between trade patterns and mobility of skilled individuals in an artificial economy; (ii) the economic impact of the 1992 EU Unique Market in the presence of sunk investments, and (iii) the impact on the Swiss economy of its participation to the European Economic Area.

Can the growth of international trade be explained by intra-industry trade models? Why products become more differentiated when trade gets freer? Why do product attributes matter in intra-industry trade models?

Three main issues: (i) Exchange rate pass-through in the presence of strategic interactions between producers. The Swiss automobile market is ideal to investigate this issue. (ii) Why do cartels emerge at a particular time with the Swiss dyestuff industry as a case study. (iii) The impact of economic integration. The integration of the Swiss economy in the EU has been a hot topic in Switzerland in 1992 in relation to its proposed participation to the European Economic Area (rejected by the people).
