This chapter describes how the spatial distribution of economic activity changes as economies develop and grow. We start with the relation between development and rural-urban migration. Moving beyond the coarse rural-urban distinction, we then focus on the continuum of locations in an economy...

This paper investigates how the mode of entry into a foreign market can be influenced by the intensity of R&D in an industry and the protection of intellectual property rights (IPR) in a recipient country. It then analyzes the link between the IPR regime and policies that place limits on the...

We study the evolution of market-oriented policies over time and across countries. We consider a model in which own and neighbors' past experiences influence policy choices through their effect on policymakers' beliefs. We estimate the model using a large panel of countries and find that it fits...

We investigate jointly the importance of contemporary country-level institutional structures and local ethnicity-specific pre-colonial institutions in shaping comparative regional development in Africa. We utilize information on the spatial distribution of African ethnicities before colonization...

We investigate the role of national institutions on regional development in a novel framework. We exploit the fact that the arbitrary political boundaries in the eve of African independence partitioned more than two hundred ethnic groups across different countries subjecting similar cultures,...

We examine the link between pre-colonial statehood and contemporary regional African development, as reflected in satellite images on light density at night. We employ a variety of historical maps to capture the former. Our within-country analysis reveals a strong positive correlation between...

We report on recent findings of a fruitful research agenda that explores the importance of ethnic-specific traits in shaping African development. First, using recent surveys from Sub-Saharan African countries, we document that individuals identify with their ethnic group as often as with the...

This study explores the consequences and origins of contemporary differences in well-being across ethnic groups within countries. We construct measures of ethnic inequality combining ethnolinguistic maps on the spatial distribution of groups with satellite images of light density at night....

Why has the expansion of women's economic and political rights coincided with economic development? This paper investigates this question, focusing on a key economic right for women: property rights. The basic hypothesis is that the process of development (i.e., capital accumulation and...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...
