We examine two sets of economies, (19th century U.S. states and 20th century less developed countries) where growth rates are positively correlated with initial levels of development to document how these dynamic increasing returns operate. We find that open economies do not display a positive...

Historically, urban growth required enough development to grow and transport significant agricultural surpluses or a government effective enough to build an empire. But there has been an explosion of poor mega-cities over the last thirty years. A simple urban model illustrates that in closed...

Africa is urbanizing rapidly, and this creates both opportunities and challenges. Labor productivity appears to be much higher in developing-world cities than in rural areas, and historically urbanization is strongly correlated with economic growth. Education seems to be a strong complement to...

New, “big” data sources allow measurement of city characteristics and outcome variables higher frequencies and finer geographic scales than ever before. However, big data will not solve large urban social science questions on its own. Big data has the most value for the study of cities when...

The fast and often chaotic urbanization of the developing world generates both economic opportunity and challenges, like contagious disease and congestion, because proximity increases both positive and negative externalities. In this paper, we review the expanding body of economic research on...

We investigate why and how the financial conditions of developing and emerging market countries (peripheral countries) can be affected by the movements in the center economies - the U.S., Japan, the Eurozone, and China. We apply a two-step approach. First, we estimate the sensitivity of...

This paper provides an empirical investigation of the medium-term determinants of current accounts for a large sample of industrial and developing countries. The analysis is based on a structural approach that highlights the roles of the fundamental macroeconomic determinants of saving and...

We investigate the medium-term determinants of the current account using a model that controls for factors related to institutional development, with a goal of informing the recent debate over the existence and relevance of the "savings glut." The economic environmental factors that we consider...

Based on a dataset of 112 emerging economies and developing countries, this paper addresses two key questions regarding the accumulation of international reserves: first, has the accumulation of reserves effectively protected countries during the 2008-09 financial crisis? And second, what...

Computer and Internet use, especially in developing countries, has expanded rapidly in recent years. Even in light of this expansion in technology adoption rates, penetration rates differ markedly between developed and developing countries and across developing countries. To identify the...
