Economies at early stages of development are often shaken by abrupt changes in growth rates, whereas in advanced economies growth rates tend to be relatively stable. To explain this pattern, we propose a theory of technological diversification. Production makes use of different input varieties,...

This paper estimates a structural model of economic geography using cross-country data on per capita income, bilateral trade, and the relative price of manufacturing goods. More than 70% of the variation in per capita income can be explained by the geography of access to markets and to sources...

This paper develops a model of economic growth and activity locating endogenously on a 3-dimensional featureless global geography. The same economic forces influence simulataneously growth, convergence, and spatial agglomeration and clustering. Economic activity is not concentrated on discrete...

This paper studies growth and inequality in China and India û two economies that account for a third of the world's population. By modelling growth and inequality as components in a joint stochastic process, the paper calibrates the impact each has on different welfare indicators and on the...

This paper investigates the determinants of countries' export performance looking in particular at the role of international product market linkages. We begin with a novel decomposition of the growth in countries' exports into the contribution from increases in external demand and from improved...

Although a rich and extensive body of theoretical research on new economic geography has emerged, empirical research remains comparatively less well developed. This paper reviews the existing empirical literature on the predictions of new economic geography models for the distribution of income...

This paper reviews the new economic geography literature, which accounts for the uneven distribution of economic activity across space in terms of a combination of love of variety preferences, increasing returns to scale and transport costs. After outlining the canonical core and periphery...

Despite the fact that importing and exporting are extremely rare firm activities, economists generally devote little attention to the role of firms when discussing international trade. This paper summarizes key differences between trading and non-trading firms, demonstrates how these differences...

This paper models the relationship between countries' distance from global economic activity, endogenous investments in education, and economic development. Firms in remote locations pay greater trade costs on both exports and intermediate imports, reducing the amount of value added left to...

This paper presents a model of social learning about the suitability of local conditions for new business ventures and explores its implications for the microeconomic patterns of economic development. I show that: i) firms tend to 'rush' into business ventures with which other firms have had...
