We identify conditions under which preferences over sets of consumption opportunities can be reduced to preferences over bundles of "commodities". We distinguish ordinal bundles, whose coordinates are defined up to monotone transformations, from cardinal bundles, whose coordinates are defined up...

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...

we identify conditions under which preferences over sets of construction opportunities can be reduced to preferences over bundles of "commodities".

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...

Using real options, we formulate an optimal stopping model for applying pest control measures when the density of a pest population fluctuates randomly. This model is applied to the control of a foliar pest of apples (the European Red Mite) via a pesticide, and solved numerically by a...

This paper analyses the decision to invest to reduce the emissions of a stock pollutant under environmental uncertainty. It shows that this decision depends on the type and level of uncertainty. When uncertainty is small, there is no simple irreversibility effect because of the tension between...

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...

We propose to analyse the hyperbolic discounting preferences effect on the innovator's research investment decision. Investing in research allows him to acquire information, and then to reduce the uncertainty of the risks of his project. We find that whatever the innovator's preferences, that is...

Prior studies disagree regarding the effectiveness of financial literacy programs, especially those offered in the workplace. To explain such measurement differences in evaluation and outcomes, we employ a stochastic life cycle model with endogenous financial knowledge accumulation to...

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, much less their financial needs. Ideally, the...
