The 1980s have seen the beginnings of a change of heart among developing country policymakers, as the import-substitution consensus of the previous decade has all but evaporated. It is paradoxical that the 1980s should have become the decade of trade liberalization in LDCs, since this has also...

This Paper examines city formation in a country whose urban population is growing steadily over time, with new cities required to accommodate this growth. In contrast to most of the literature there is immobility of housing and urban infrastructure, and investment in these assets is taken on the...

Large cities produce more output per capita than small cities. This may occur because more talented individuals sort into large cities, because large cities select more productive entrepreneurs and firms, or because of agglomeration economies. We develop a model of systems of cities that...

This paper proposes a simple theory of a system of cities that decomposes the determinants of the city size distribution into three main components: efficiency, amenities, and frictions. Higher efficiency and better amenities lead to larger cities, but also to greater frictions through...

We analyze the role of optimal income taxation across different local labor markets. Should labor in large cities be taxed differently than in small cities? We find that a planner who needs to raise revenue and is constrained by free mobility of labor across cities does not choose equal taxes...

Individual earnings are higher in bigger cities. We consider three reasons: spatial sorting of initially more productive workers, static advantages associated with workers' current location, and learning by working in big cities. Using rich administrative data for Spain, we find that workers in...

If in general, financial deepening aids economic growth, then financial repression should be harmful. We use a natural experiment – the change in the English usury laws in 1714 – to analyse the effects of interest rate restrictions. Based on a sample of individual loan transactions, we...

Whether diversity or specialization of economic activity better promotes technological change and subsequent economic growth has been the subject of a heated debate in the economics literature. The purpose of this paper is to consider the effect of the composition of economic activity on...

This Paper discusses the challenges confronting developing countries seeking to overcome discrimination in world trade rules and policies. The major sources of discrimination in both developed and developing countries in the areas of market access opportunities and WTO disciplines are briefly...

We study the effects of differences in local financial development within an integrated financial market. To do so, we construct a new indicator of financial development by estimating a regional effect on the probability that, ceteris paribus, a household is shut off from the credit market. By...
