We study how the city system is affected by the possibility for the members of the same cultural diaspora to interact across different cities. In so doing, we propose a simple two-city model with two mobile cultural groups. A localized externality fosters the productivity of individuals when...

We model technological and financial innovation as reflecting the decisions of profit maximizing agents and explore the implications for economic growth. We start with a Schumpeterian endogenous growth model where entrepreneurs earn monopoly profits by inventing better goods and financiers arise...

This research suggests that the evolution of entrepreneurial spirit played a significant role in the process of economic development and the evolution of inequality within and across societies. The study argues that entrepreneurial spirit evolved non-monotonically in the course of human history....

This research suggests that the evolution of entrepreneurial spirit played a significant role in the process of economic development and the dynamics of inequality within and across societies. The study argues that entrepreneurial spirit evolved non-monotonically in the course of human history....

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 investigate the role of deeply-rooted pre-colonial ethnic institutions in shaping comparative regional development within African countries. We combine information on the spatial distribution of ethnicities before colonization with regional variation in contemporary economic performance, as...

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....
