Sampling Interval and estimated Betas : Implications for the Presence of Transitory Components in Stock Prices
(Université de Montréal. Département de sciences économiques., 1998)We provide a theoretical framework to explain the empirical finding that the estimated betas are sensitive to the sampling interval even when using continuously compounded returns. We suppose that stock prices have both permanent and transitory components. ... -
School Choice with Control
(Université de Montréal. Département de sciences économiques., 2010-06)Controlled choice over public schools is a common policy of school boards in the United States.

Sharing the Cost of a Public Good without Subsidies
(Université de Montréal. Département de sciences économiques., 2006-07)We study the construction of a social ordering function for the case of a public good financed by contributions from the population, and we extend the analysis of Maniquet and Sprumont (2004) to the case when contributions cannot be negative, i.e. ... -
Sharing the Cost of a Public Good: an Incentive-Constrained Axiomatic Approach
(Université de Montréal. Département de sciences économiques., 2006-07)We study the problem of provision and cost-sharing of a public good in large economies where exclusion, complete or partial, is possible. We search for incentive-constrained efficient allocation rules that display fairness properties. Population ... -
Sharp test for equilibrium uniqueness in discrete games with a flexible information structure
(Université de Montréal. Département de sciences économiques., 2018-12)I propose a test for an assumption commonly maintained when estimating static discrete games of incomplete information, i.e. the assumption of equilibrium uniqueness in the data generating process. The test is appealing for several reasons. It allows ... -
