Testing for Welfare Comparisons when Populations Differ in Size

Duclos, Jean-Yves; Zabsonré, Agnès - Centre Interuniversitaire sur le Risque, les Politiques … - 2010

Assessments of social welfare do not usually take into account population sizes. This can lead to serious social evaluation flaws, particularly in contexts in which policies can affect demographic growth. We develop in this paper a little-known though ethically attractive approach to correcting...

Testing for Poverty Dominance: an Application to Canada

Chen, Wen-Hao; Duclos, Jean-Yves - Centre Interuniversitaire sur le Risque, les Politiques … - 2008

The paper proposes and applies statistical tests for poverty dominance that check for whether poverty comparisons can be made robustly over ranges of poverty lines and classes of poverty indices. This helps provide both normative and statistical confidence in establishing poverty rankings across...

Using a Canadian-American Natural Experiment to Study Relative Efficiencies of Social Welfare Payment Systems

Tanguay, Georges; Hunt, Gary; Marceau, Nicolas - Centre Interuniversitaire sur le Risque, les Politiques … - 2002

We study whether social welfare recipients may end up paying more for their grocery if social welfare payments are more concentrated over time. We first present a theoretical model showing that lower incomes in general and a lower lower bound of the income distribution lead to less mobility for...

Equity and Equality

Duclos, Jean-Yves - Centre Interuniversitaire sur le Risque, les Politiques … - 2006

Is horizontal equity (HE) the "most widely accepted principle of equity"? Or does it stand in "opposition to the advancement of human welfare"? This paper argues that the case for the HE principle is not as straightforward as is usually thought and that it requires advanced notions of justice...

Mirman, Leonard J.; Santugini, Marc - Centre Interuniversitaire sur le Risque, les Politiques … - 2011

Building on Kihlstrom and Mirman (1974)’s formulation of risk aversion in the case of multidimensional utility functions, we study the effect of risk aversion on optimal behavior in a general consumer’s maximization problem under uncertainty. We completely characterize the relationship...

The Income Effect under Uncertainty: a Slutsky-Like Decomposition with Risk Aversion

Antoniadou, Elena; Mirman, Leonard J.; Santugini, Marc - Centre Interuniversitaire sur le Risque, les Politiques … - 2013

We study the effect of changing income on optimal decisions in the multidimensional expected utility framework with strongly separable preferences. Using the Kihlstrom and Mirman (1974) (KM) utility representation, we show that the effect of changing income can be decomposed into a modified...

Evidence on Individual Preferences for Longevity Risk

Delprat, G.; Leroux, M.-L.; Michaud, P.-C. - Centre Interuniversitaire sur le Risque, les Politiques … - 2013

The standard model of intertemporal choice assumes risk neutrality toward the length of life: due to additivity, agents are not sensitive to a mean preserving spread in the length of life. Using a survey fielded in the RAND American Life Panel (ALP), this paper provides empirical evidence on...

Health Club Attendance, Expectations and Self-Control

Garon, Jean-Denis; Masse, Alix; Michaud, Pierre-Carl - Centre Interuniversitaire sur le Risque, les Politiques … - 2013

Using a unique dataset on health club attendance from Quebec, we look at the relationship between actual and expected attendance and how these relate to measures of self-control. We find that a large majority of contract choices appear inconsistent if we do not take into account the commitment...

Uncertain Bequest Needs and Long-Term Insurance Contracts

Fei, Wenan; Fluet, Claude; Schlesinger, Harris - Centre Interuniversitaire sur le Risque, les Politiques … - 2007

We examine how long-term life insurance contracts can be designed to incorporate uncertain future bequest needs. An … individual who buys a life insurance contract early in life is often uncertain about the make up of his or her future family … two equivalent long-term life insurance contracts that are incentive compatible and achieve a higher welfare level than …
