Economic activities are highly clustered. Why is geographic concentration becoming a predominant feature of modern economies? On the basis of the empirical models developed by the 'new' theories of international trade, our answer is that increasing returns are the driving force of economic...

This paper presents an integrated model of urban agglomeration economies within a computable general equilibrium (CGE) model of global economic activity, energy use and carbon emissions to explore the theoretical and empirical nature of the interdependence of cities and the world economy in a...

The standard two-country model of international trade with monopolistic competition predicts a more-than-proportional relationship between a country's share of world production of a good and its share of world demand for that same good, a result known as the "home market effect". We first show...

This paper emphasises the importance of the political-institutional dimension in the understanding of the spatial distribution of economic activity. We introduce the notion of Territorial Authority Scale, which refers to the degree of devolution (towards sub-national tiers of government)...

We use transaction-level data to study changes in the concentration of US imports. Concentration has fallen in the typical industry, while it is stable by industry and country of origin. The fall in concentration is driven by the extensive margin: the number of exporting firm has grown, and the...

This paper investigates theoretically and empirically the endogenous investment decision of firms conditioning on export decision. It shows that theoretically, whatever the form of preferences, firms that start exporting invest more and grow more than the others. However, it is shown that when...

The paper examines how country tax differences affect a multinational enterprise's choice to centralize or de-centralize its decision structure. Within a simple model that emphasizes the multiple conflicting roles of transfer prices in MNEs – here, as a strategic pre-commitment device and a...

We examine how a multinational’s choice to centralize or de-centralize its decision structure is affected by country tax differentials. Within a simple model that emphasizes the multiple conflicting roles of transfer prices in MNEs - here, as a strategic pre-commitment device and a tax...

This paper investigates the determinants of vertical integration. We first derive a number of predictions regarding the relationship between technology intensity and vertical integration from a simple model with nancial imperfections andincomplete contracts. Then, we investigate these...

This paper analyses the reasons behind India lagging behind East and South East Asian economies in participating in international production networks, on which growth in manufacturing has become increasingly dependent in the contemporary world. Since multinational firms are the main coordinating...
