Working Papers

  1. Structure of Income Inequality and Household Leverage: Theory and Cross-Country Evidence (with Rémi Bazillier and Jérôme Héricourt) CEPII Working Paper (2017-01)

Lettre du CEPII N°379. In the media: Le Monde, The Conversation

Abstract: How do income inequality and its structure affect the volume of credit? We extend the theoretical framework by Kumhof et al. (2015) to distinguish between upper, middle and low-income classes, and show that most of the positive impact of inequality on credit predicted by Kumhof et al. (2015) should be driven by the share of total output owned by middle classes. These theoretical predictions are empirically confirmed by a study based on a 44 countries dataset over the period 1970-2014. Exogenous variations of inequality are identified with a new instrument variable, the total number of International Labor Organization conventions signed at the country-level. Using various indicators of inequality, we support a positive impact of inequality concentrated on household leverage, and investigate how this average impact is distorted along income distribution. Consistently with the theoretical setting, our results tend to show that most of the impact is driven by middle classes, rather than low-income households. Consistently, our results hold mostly for developed countries.

      2. Fire Sales and Debt Maturity (Last version of the paper on request)

Abstract: How does debt maturity structure affect fire sales? By introducing debt maturity in a Fisherian deflation model, I demonstrate how it could trigger financial crises. Using a stock-flow analysis, I show that long-term debt could alleviate the risk of current binding collateral constraint, but an excessive reliance on long-term debt could generate future binding collateral constraints over long horizons. It is empirically confirmed by a study based on 122 developing countries over the period 1970-2012. I highlight that debt maturity structure is a good early-warning indicator of fire sales, which provides information that adds up to the level of external debt.
