The Death and Life of Great British Cities
écrit avec S. Heblich, A. Trew and Y. Zylberberg
This paper studies how cities’ industrial structure shapes their life and death. Our analysis exploits the large heterogeneity in the early composition of English and Welsh cities. We extract built-up clusters from early historical maps, identify settlements at the onset of the nineteenth century, and isolate exogenous variation in the nature of their rise during the transformation of the economy by the end of the nineteenth century. We then estimate the causal impact of cities’ population and industrial specialization on their later dynamics. We find that cities specializ- ing in a small number of industries decline in the long run. We develop a dynamic spatial model of cities to isolate the forces which govern their life and death. Intratemporally, the model captures the role of amenities, land, local productivity and trade in explaining the distribution of economic activity across industries and cities. Intertemporally, the model can disentangle the role of aggregate industry dynamics from city-specific externalities. We find that the long-run dynamics of English and Welsh cities is explained to a large extent by such dynamic externalities à la Jacobs.

Distributional Growth Accounting: Education and the Reduction of Global Poverty, 1980-2022
This article studies the role played by education in the decline of global poverty. In a companion paper, I estimate that the rise of government redistribution in the form of cash transfers, education, healthcare, and other public services accounts for 30% of worldwide poverty reduction since 1980 (Gethin, 2023). In this paper, I incorporate in this analysis the causal impact of schooling on pretax incomes, combining survey microdata covering 95% of the world’s population with a simple model of education and the wage structure. Private returns to schooling account for 50-60% of global economic growth, 60-70% of income gains among the world’s poorest 20% individuals, and 60-90% of the decline in global gender inequality since 1980. Combining direct redistribution and indirect investment benefits from education brings the total contribution of public policies to global poverty reduction to 50-80% or more.
