This paper develops a general equilibrium Ricardian model with transaction costs to investigate the determinants of the firm's sourcing decision. It derives conditions under which different sourcing choices and corresponding trade patterns occur in general equilibrium. These conditions suggest...

The paper uses a modern adaptation of the Ricardian model which incorporates monopolistic competition and multiple factors to derive a MacDougall-type relation between a country’s nternational competitiveness at the industry level and its productivity performance. This relation is implemented...

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 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...

This paper develops a Ricardian model of trade in which there are indivisibilities in both production and consumption. Indivisibilities give rise to new results compared to the standard model with perfectly divisible production and consumption. Production indivisibility may result in complete...

Balassa Index (Balassa 1965) is widely used in the literature to measure country-sector Revealed Comparative Advantage (RCA). However, being computed on observed trade flows, it mixes up all the factors influencing trade flows. In particular, Balassa Index cannot isolate exporter-sector (ex...

This paper presents a new database of revealed comparative advantage (RCA) measures based on the recent index of RCA proposed by Costinot et al. (2012). This new index conceptually fits the ex ante and country-sector specific nature of the Ricardian comparative advantage better than the...

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,...
