1. Abadie, Alberto and Sebastien Gay, 2006, The Impact of Presumed Consent Legislation on Cadaveric Organ Donation: A Cross-Country Study, Journal of Health Economics, Elsevier, vol. 25(4), pages 599-620, July.

   We show the impact of presumed consent laws on donation rates. Using a panel data of 22 countries over the period 1993-2003, we find a positive and sizable effect (25-30%) of presumed consent legislation on organ donation rates.

2. Gay, Sebastien, 2005, Early Preschool Interventions: The End of the Myth? The Perry Preschool Example Revisited, Mimeo University of Chicago. Best Graduate Student Paper at the Illinois Economic Association.

   We reanalyze the previously well-accepted study of the impact of the Perry preschool and demonstrate that there is only some little significant effect of pre-education on crime.

3. Fevrier, Philippe and Sebastien Gay, 2004, Informed Consent versus Presumed Consent: the Role of the Family in Organ Donation, Mimeo University of Chicago.

   We challenge the usual convention that presumed consent is a better system than informed consent for organ donation.

4. Gay, Sebastien, 2002, Diversification and Performance of Companies in the Construction Materials Market, GRID Working Papers.

   We show the impact of diversification on the performance of companies in the cement industry. We find that diversification can have a negative effect of performance of companies in this particular sector of the economy.

5. Gay, Sebastien, 2008, The Impact of The Bosman Act on the Wages of Soccer Players in Europe.

   Work in progress

   The tax rate on income for soccer players varies substantially in Europe, which has an important impact on the distribution of talent across countries. We measure how the different taxes change the distribution of talents in European soccer.

6. Gay, Sebastien, 2008, Private Security versus Public Security: Substitutes or Complements?

   Work in progress

   This paper assesses the effect of private security guards on crime rates in the United States between 1993 and 2003 and measures the substitution effect between public and private security. We find a significantly negative effect on crime using the 9/11 attack, employment in private ambulance services, and employment in grocery stores as instruments.
