In this paper I quantify the welfare gains of the 2004 EU enlargement as a result of the abolition of border controls, both for incumbents and for new members. I build a multi-sector Ricardian model, allowing for linkages across sectors, similar to the one in Caliendro and Parro (2011). As with...

This paper develops an approach for quantifying the importance of different sources of comparative advantage for country welfare. To explain patterns of specialization, I present a multi-country trade model that extends Eaton and Kortum (2002) to predict industry trade ows. In this framework,...

The so-called Ricardian model of contemporary economic textbooks differs significantly from the famous numerical example included in chapter seven of the Principles. The difference is not merely with respect to the definition of the four numbers, but also in terms of underlying proposition,...

The theory of comparative advantage is at the core of neoclassical trade theory. Yet we know little about its implications for how nations should conduct their trade policy. For example, should import sectors with weaker comparative advantage be protected more? Conversely, should export sectors...

Dieser Beitrag soll einen Überblick und eine Systematik im Hinblick auf die aktuellen Beiträge zum Phänomen der Fragmentierung geben. Während man im Zusammenhang mit der Ausweitung des Nord-Süd-Handels von einer "horizontalen Globalisierung" spricht, gilt Fragmentierung als Ausdruck einer...

This paper focuses on the possible effects of eastern enlargement not only on trade between the entrants and current members, but on the location of production in the enlarged union. The key notion is that of cross-border production sharing, also known as cross-border fragmentation of...

This paper addresses the lack of connection between theory and empirics in most export diversification - economic development studies. We provide a Ricardian-based theoretical explanation of countries' relative export variety as a function of the level of technology and country size assessed...

Conditions for the occurrence of immiserizing growth and the Metzler paradox are analysed in the Ricardian model when consumers in the foreign country have Leontief preferences while consumers in the home country have Cobb-Douglas preferences. By using specific functional forms, the conditions...
