In this paper, we show that behavioral features can be obtained at a group level when the individuals of the group are heterogeneous enough. More precisely, starting from a standard model of Pareto optimal allocations, with expected utility maximizers and exponential dis- counting, but allowing...

Many empirical and behavioral studies underline the idea of a non-flat term structure of subjective interest rates with a decreasing slope. Using an empirical test, this paper aims at identifying in individual behaviors whether agents see their psychological value of time decreasing or not. We...

Many empirical and behavioral studies identify a decreasing slope in the term structure of subjective discount rates. Using an experimental methodology based on “free-time” relative comparisons, this paper aims to identify in individual behaviors whether agents see their psychological value...

This article provides an overview of the literature on the psychological value of time. It discusses various determinants of the discount rate and the possibility of hyperbolic discounting. The historical approach helps us to trace the origins of the concept of psychological value of time. This...

Kimball, 1990a and Kimball, 1990b established that income risk increases the marginal propensity to consume if and only if absolute prudence decreases. We characterize decreasing and increasing multivariate prudence and show that a multidimensional risk increases the marginal propensity to...

Following recent developments in the literature about portfolio choices (Flavin and Yamashita, 2002; Cocco, 2004; Yao and Zhang, 2005), this paper analyses the empirical link between stockholding and housing wealth. We use the French wealth survey (Enquête Patrimoine2004, Insee) that give us detailed...
