We examine how firm heterogeneity influences aggregate welfare through endogenous firm selection. We consider a homogeneous firm model that is a special case of a heterogeneous firm model with a degenerate productivity distribution. Keeping all structural parameters besides the productivity...

This paper establishes that production unbundling has coincided with an inscreasing role of input costs in shaping the pattern of comparative advantage. I show that the wedge in the cost of the input bundle across countries in a multisectoral Ricardian model is given by a composite index of...

L’article montre qu’une politique d’amélioration des infrastructures d’une région pauvre permet de réduire l’inégalité spatiale mais peut aboutir à une géographie moins efficace et un taux de croissance plus faible. Les effets inverses sont obtenus pour une politique qui...

Our findings indicate that the former split of CEECs in terms of business cycles synchronization with the euro area does not hold as soon as the recent period is taken into account. While Slovenia and Poland continue to appear as suitable EMU members due to their high – and growing – GDP...

In September 1957, the International Economic Association held a conference at The Hague on the “Economic Consequences of the Size of Nations”, which proceedings were published in 1960. Fifty years later, while the economic environment has dramatically changed, the issues put forward and...

This paper checks if differences in market size can explain the retardation of the Industrial Revolution in France compared to Britain. It uses an exceptional source on French domestic trade in a variety of goods in the late eighteenth century: the Tableaux du Maximum. The first part presents...

The authors compare the European Community's "trade fundamentals" prevailing in the 1960s with those applying in Arab countries today. The fundamentals differ significantly-Arab countries trade much less with each other than EC members did, and the importance of such trade in GDP varies greatly....

This paper provides evidence on the long-term impact of market potential on economic development. It derives from the New Economic Geography literature a structural estimation where the level of factors' income of a country is related to its export capacity, labelled Market Access (MA) by...

For nearly two decades, growth of international trade has been underpinned by the development of intermediate goods cross exchanges resulting from a new international division of labour. The share of trade in inputs, also called vertical trade, has dramatically increased. Simultaneously, there...

This paper describes the possible impact of multi-speed integration on the location of economic activities in Europe. We present a model where two countries integrate their economies and leave a third temporarily outside because of its lower income. We analyse the effect of different integration...
