Research interest: My main research interests lie at the frontier between urban economics and public finance. The research I have conducted so far has focused on understanding how to design spatial policies to ensure efficiency, while preserving a fair and equitable access for all.

Fields of interest: Applied Microeconomics, with focus on Urban Economics and Public Finance.

Abstract: This paper studies the performance of New Towns, i.e., planned large urban subcenters, as a central tool to accommodate the global rise in urbanization. A spatial quantifiable general equilibrium framework suitable to study large-scale urban master plans is presented. The framework is then used to investigate the equilibrium effects of five New Towns developed in the 1970s in Paris’ metropolitan area. By 2015, these developments appear to have increased metropolitan GDP, reduced commuting times and reduced income inequality. The results obtained for Paris’ metropolitan area are externally validated by a reduced form – Difference-in-Difference Event Study – approach on all 314 New Towns developed worldwide between 1992 and 2012.

Abstract: This paper proposes a novel approach to evaluate location decisions for public facilities. The approach addresses, not only the standard distance-minimizing problem, but also the endogenous location decisions of individuals. To do so, I develop a quantifiable general equilibrium model with endogenous (residential and commercial) densities, housing prices, commutes to work and public facilities, as well as public facility characteristics. The latter includes a facility’s location, quality, district and capacity. I apply the framework to secondary schools in Paris’ greater region at a 1km2 geographical scale. The analysis reveals that the observed location decisions made between 2001 and 2015 underestimate the endogenous reaction of individuals. A more decentralized strategy is predicted to increase welfare growth by 10 percentage points on average, mostly via shorter commutes and lower housing prices.
  • Regional Borders, Commuting and Transport Network Integration, KOF Working Paper, 2020. [WP version, Dec 2020]

R&R at The Review of Economics and Statistics.


Abstract: I study how and why economic activity varies around regional borders. Spatial quasi-experimental variation around French departmental borders reveals discontinuous commuting and residential patterns. To tackle the endogenous border placement problem, I exploit a geometric border design proposed during the French Revolution. I then calibrate a spatial quantifiable general equilibrium framework to structurally match the quasi-experimental estimates. The commuting and residential discontinuities are well explained by a 7km bilateral distance penalty when crossing regional borders, which is the consequence of the decentralized planning and development of local transport networks. Policy simulation shows that integrating local transport networks leads to a 11.7% average growth in real per capita residential income.

Abstract: We document an unprecedented change in the size and the quality of China's transport-infrastructure network between 2000 and 2013. This documentation is based on hand-collected and digitized data on roads and railways. The changes are summarized and portrayed as shortest-possible transport times of people and goods between 330 prefectures of mainland China. A quantitative model of China's prefectures and a Rest of the World, featuring both goods trade and migration, suggests that the long-run consequences of the transport-infrastructure changes induce regional convergence of lagging-behind prefectures in terms of population density and, to a lesser extent, in terms of real per-capita income. Not only changes in highway and high-speed-railway networks but also ones in lower-level road and railway networks are quantitatively important. Key drivers behind the effects are the facilitation of goods transport as well as technology diffusion, while the reduction of mobility costs and the diffusion of amenities appear less important.

  • Fiscal Autonomy and Self-Determination (with Christian Stettler), CESifo Working paper No. 9445. [WP version, Dec 2021]


Abstract: This paper studies the equilibrium effects of local fiscal autonomy accounting for benefits from self-determination. It proposes a quantifiable structural equilibrium framework in which imperfectly mobile heterogeneous households sort themselves across jurisdictions under endogenous public good provision. We calibrate the framework to fit the economic and geographic characteristics of the Canton of Bern using household-level data. In particular, we exploit quasi-natural policy variation in voting rights to quantify benefits from self-determination, and employ machine learning methods to accurately represent the local political process. We find that restricting local fiscal autonomy decreases welfare for (almost) all households.
