Relative Uncertainty and Additively Representable Set Rankings
(Université de Montréal. Département de sciences économiques., 2004)
This paper proposes a definition of relative uncertainty aversion for decision models under complete uncertainty. It is shown that, for a large class of decision rules characterized by a set of plausible axioms, the new ...
Reference Groups and Individual Deprivation
(Université de Montréal. Département de sciences économiques., 2004)
We provide an axiomatization of Yitzhaki’s index of individual deprivation. Our result differs from an earlier characterization due to Ebert and Moyes in the way the reference group of an individual is represented in the ...
Intertemporal Social Evaluation
(Université de Montréal. Département de sciences économiques., 2005)
Intertemporal social-evaluation rules provide us with social criteria that can be used to assess the relative desirability of utility distributions across generations. The trade-offs between the well-being of different ...
Critical-Level Population Principles and the Repugnant Conclusion
(Université de Montréal. Département de sciences économiques., 2002)
Critical-level generalized-utilitarian population principles with positive critical levels pro-vide an ethically attractive way of avoiding the repugnant conclusion. We discuss the axiomatic foundations of critical-level ...
Maximal-Element Rationalizability
(Université de Montréal. Département de sciences économiques., 2002)
We examine the maximal-element rationalizability of choice functions with arbitrary do-mains. While rationality formulated in terms of the choice of greatest elements according to a rationalizing relation has been analyzed ...
Harsanyi’s Social Aggregation Theorem : A Multi-Profile Approach with Variable-Population Extensions
(Université de Montréal. Département de sciences économiques., 2003)
This paper provides new versions of Harsanyi’s social aggregation theorem that are formulated in terms of prospects rather than lotteries. Strengthening an earlier result, fixed-population ex-ante utilitarianism is ...
Population Ethics and the Value of Life
(Université de Montréal. Département de sciences économiques., 2003)
Public policies often involve choices of alternatives in which the size and the composition of the population may vary. Examples are the allocation of resources to prenatal care and the design of aid packages to developing ...
Domain Closedness Conditions and Rational Choice
(Université de Montréal. Département de sciences économiques., 2005)
The rationalizability of a choice function on an arbitrary domain under various coherence properties has received a considerable amount of attention both in the long-established and in the recent literature. Because domain ...
Social Choice: Recent Developments
(Université de Montréal. Département de sciences économiques., 2006)
In the past quarter century, there has been a dramatic shift of focus in social choice theory, with structured sets of alternatives and restricted domains of the sort encountered in economic problems coming to the fore. ...
Dynamic Measures of Individual Deprivation
(Université de Montréal. Département de sciences économiques., 2005)
We introduce and axiomatize a one-parameter class of individual deprivation measures. Motivated by a suggestion of Runciman, we modify Yitzhaki’s index by multiplying it by a function that is interpreted as measuring the ...
