Axiomatic analysis of intergenerational social preferences over infinite streams of well-being
faces the following dilemma. Equal treatment of generations combined with sensitivity for the …

Standard cost-effectiveness models compare incremental cost increases to incremental
average gains in health, commonly expressed in Quality-Adjusted Life Years (QALYs). Our …

This article provides an axiomatic characterization of quasi-hyperbolic discounting and a
more general class of semi-hyperbolic preferences. We impose consistency restrictions …

The discounted utilitarian criterion for infinite horizon social choice has been criticized for
treating generations unequally. We propose an extended rank-discounted utilitarian (ERDU) …

We provide theoretical foundations for several common (nested) representations of intrinsic
linear habit formation. Our axiomatization introduces an intertemporal theory of weaning a …

What ethical criterion for intergenerational justice should be adopted, eg, when faced with
the task of managing the global environment? Koopmans' axiomatization of discounted …

We introduce a ranking of multidimensional alternatives, including uncertain prospects as a
particular case, when these objects can be given a matrix form. This ranking is separable in …

We study preferences over lotteries in which both the prize and the payment date are
uncertain. In particular, a time lottery is one in which the prize is fixed but the date is random …

We study intertemporal decision making under uncertainty in a purely subjective framework.
The concept of stationarity, introduced by Koopmans for deterministic discounted utility, is …

We present revealed-preference characterizations of the most common models of
intertemporal choice: the model of exponentially discounted concave utility, and some of its …
