This paper proposes a new axiomatic model of intertemporal choice that allows for dynamic inconsistency. We weaken the classical assumption of stationarity into two related axioms: stationarity in the short-term and stationarity in the long-term. We obtain a model with two independent discount...

The discounting of future felicity flows transposes to the intertemporal optimization context the assumption of interest-bearing wealth or savings. The validity of the hypothesis has been challenged by several empirical (ir)regularities and by the theoretical implications for human decision...

Previous work has shown that preferences are not always stable across time, but surprisingly little is known about the reasons for this instability. I examine whether variation in people's emotions over time predicts changes in preferences. Using a large panel data set, I find that within-person...

We develop a dynamic model of monopolistic competition which sheds light on how the interplay between the degree of product differentiation and intertemporal elasticity of substitution affects the steady-state equilibrium. Consumers love variety and split their labor endowment between wage...

Intertemporal choices are a ubiquitous class of decisions that involve selecting between outcomes available at different times in the future. We investigated the neural systems supporting intertemporal decisions in healthy younger and older adults. Using functional neuroimaging, we find that...

We study a model of task completion with the opportunity to learn about own self-control problems over time. While the agent is initially uncertain about her future self-control, in each period she can choose to learn about it by paying a non-negative learning cost and spending one period. If...

Traditionally, economic models have attributed procrastination to present bias. However, procrastination may also arise when individuals derive anticipatory utility from holding motivated, overly optimistic beliefs about the workload they need to complete. This study provides a rigorous...

Hyperbolic discounting and lack of self-control are different phenomena that share the property of dynamic inconsistency. Despite being different, these two concepts have been extensively conflated and confused in Economics. I review the definitions and properties of both concepts, the...

Procrastination is often attributed to time-inconsistent preferences but may also arise when individuals derive anticipatory utility from holding optimistic beliefs about their future effort costs. This study provides a rigorous empirical test for this notion of ‘motivated procrastination’....
