This paper shows that there is a positive and statistically significant correlation between the short-term discount rate over a monetary reward and the short-term discount rate over a primary reward (chocolate). This correlation, however, is absent among subjects who do not like chocolate and...

The purpose of the study is to better understand human capital investment decisions of the working poor, and to collect information that can be used to design a policy to induce the poor to invest in human capital. We use laboratory experimental methodology to elicit the preferences and observe...

We reconcile �findings from the Multiple Price List method (Andersen et al., 2008) and the Convex Time Budget method (Andreoni and Sprenger, 2012a) that seem to have generated a heated debate in the time preference literature. Specifi�cally, we discuss the claims of Andreoni and Sprenger...

We propose a mathematical model of `approximate' interpersonal comparisons of well-being, in terms of an incomplete preorder over a space of `psychophysical states'. We argue that this model is consistent with people's intuitions about interpersonal comparisons, intertemporal preferences, and...

We replicate the Stanford marshmallow experiment with a sample of 141 preschoolers and find a correlation between lack of self-control and 2D:4D digit ratio. Children with low 2D:4D digit ratio are less likely to delay gratification. Low 2D:4D digit ratio may indicate high fetal testosterone. If...

Let X be a set of states, and let I be an infinite indexing set. Our first main result states that any separable, permutation-invariant preference order () on X^I admits an additive representation. That is: there exists a linearly ordered abelian group A and a `utility function' u:X--A such...

It is well-known that subjects can exhibit a preference for increasing payments. Smith (2009a) makes a related prediction that the difference between the preference increasing wage payments and the preference for increasing non-wage payments will be largest for intermediate payments. We find...

We define an intergenerational social welfare function Sigma from |R^|N (the set of all infinite-horizon utility streams) into *|R (the ordered field of hyperreal numbers). The function Sigma is continuous, linear, and increasing, and is well-defined even on unbounded (e.g. exponentially...

This paper experimentally studies the effects of background music and sound on the preference of the decision makers for rewards in pairwise intertemporal choice tasks and lottery choice tasks. The participants took part in the current experiment, involving four treatments: (1) the familiar...
