Samuel LigonniereI am an Associate Professor of Economics at the University of Strasbourg. I hold a Ph.D. in Economics from LEM-CNRS University of Lille and from Ecole Normale Supérieure Paris-Saclay.

My research interests are international macroeconomics and inequality, with an emphasis on financial cycles. I explore the circular relationship between income inequality, household credit and financial crises. I also investigate the consequences and the policy implications of these cycles.

My Curriculum Vitae is here in english and in french.

Working Papers

  1. Fire Sales and Debt Maturity (Available upon request)

Abstract: How does debt maturity structure affect fire sales? I show how debt maturity can trigger financial crises by introducing debt maturity in a Fisherian deflation model. In particular, using a stock/flow analysis, I find (i) that an excessive reliance on short-term debt exacerbates the risk of financial crises due to fire sales and (ii) that this risk is driven by a rise in the term premium. I confirm these two testable predictions with an empirical study of data from 69 emerging and developing countries from 1970 to 2017. This shows that debt maturity structure is a good early warning indicator of financial crises, which adds information compared with the level of external debt alone.
