In this paper we analyze the impact of benefits on the length of welfare spells. It introduces a ``natural experiment'' approach of comparing the length of welfare spells before and after a major reform of the welfare program that took place in the Province of Québec in August 1989. An...

McCausland (2004a) describes a new theory of random consumer demand. Theoretically consistent random demand can be represented by a "regular" "L-utility" function on the consumption set X. The present paper is about Bayesian inference for regular L-utility functions. We express prior and...

This paper develops a high-frequency risk measure, the Liquidity-adjusted Intraday Value at Risk (LIVaR). Our objective is to explicitly consider the endogenous liquidity dimension associated with order size. Taking liquidity into consideration when using intraday data is important because...

In Canada, a policy aiming at helping single parents on social assistance become self-reliant was implemented on an experimental basis. The Self-Sufficiency Entry Effects Demonstration randomly selected a sample of 4,134 single parents who had applied for welfare between January 1994 and March...

The objective of this paper is to investigate the use of tick-by-tick data for market risk measurement. We propose an Intraday Value at Risk (IVaR) at different horizons based on irregularly time-spaced high-frequency data by using an intraday Monte Carlo simulation. An UHF-GARCH model extending...

We provide an analysis of the effect of physician payment methods on their hospital patients’ length of stay and risk of readmission. To do so, we exploit a major reform implemented in Quebec (Canada) in 1999. The Quebec Government introduced an optional mixed compensation (MC) scheme for...

Dans ce travail, nous cherchons à déterminer l'impact des mesures actives d'insertion sur les transitions des jeunes prestataires masculins de l'aide de dernier recours sur le marché du travail. La richesse des données à notre disposition nous permet de recréer de façon très détaillée...

In this paper, we address the dynamics associated with living-arrangement decisions of sick, elderly individuals. Using data from the Panel Study of Income Dynamics and its Parental Health Supplement, we construct the complete living-arrangement histories of elderly individuals in need of care....

This paper studies the application of the simulated method of moments (SMM) for the estimation of nonlinear dynamic stochastic general equilibrium (DSGE) models. Monte Carlo analysis is employed to examine the small-sample properties of SMM in specifications with different curvature. Results...

We develop a Markov-switching GARCH model (MS-GARCH) wherein the conditional mean and variance switch in time from one GARCH process to another. The switching is governed by a hidden Markov chain. We provide sufficient conditions for geometric ergodicity and existence of moments of the process....
