We examine stability of competitive equilibrium in an N-country world economy with capital accumulation, where each country can have either increasing marginal impatience (IMI) or decreasing marginal impatience (DMI). The necessary and sufficient condition for stability is shown as positive...

A growing number of empirical studies have aimed to identify dynamic inconsistency by combining diverse sets of elicitation designs and tested the extent to which this important component of individual heterogeneity predicts behavior; however, relatively little consensus on which designs are the...

In a two-country model with habit formation, we focus on interdependent macroeconomic adjustments to global and country-specific income shocks. Global habits and habit differentials play key roles in the global equilibrium dynamics, possibly nonmonotonic, and in the determination of...

This research is the first to examine dynamic general equilibrium in a growing two-country economy under decreasing marginal impatience (DMI). The stability condition is shown to be more restrictive than in the case of an endowment economy and/or under increasing marginal impatience (IMI). By...

In view of the finding that debtors are likely to be more obese than nondebtors, we investigate whether interpersonal differences in body mass are, as in the case of debt behavior, related to those in time discounting and time discounting anomalies. The effects of time discounting on body mass...

The delay effect, that people discount the near future more than the distant future, has not been verified rigorously. An experiment conducted by us in China confirms that, by separating the delay from the interval, the delay effect exists only within a short delay. The results are reliable,...

Based on unique panel data from a five-wave internet survey in Japan, we show how the coronavirus disease 2019 pandemic affected people’s prospect-theory risk preferences, especially in the loss domain. The panel analysis indicates that with the spread of the pandemic, diminishing sensitivity...

We examine and verify our hypothesis from a theoretical model that parents are more likely to be authoritative if they are from a wealthy family. Using the data from the Preference Parameters Study of Osaka University, Japan, we find that there are significantly positive associations between...

Designing efficient environmental policies requires knowledge about households’ preference parameters for their intertemporal decisions. By conducting an original Internet-based survey using Japanese participants (n=2,906) and a follow-up survey (n=1,407), we examine how people evaluate...
