Incorporating weakly nonseparable preferences into the familiar time-preference model, we emphasize a role of steady-state welfare changes in determining the effect of permanent tariffs on the current account. The effect consists of: a welfare effect, due to steady-state welfare changes, which...

Analysis of an original nationwide Internet survey reveals that health-related behavior shows associations with three aspects of time discounting: (i) impatience, measured by the overall discount rate; (ii) present bias, measured by the degree of declining impatience in the generalized hyperbolic...

We propose a model of parental altruism in relation with child habit formation, where children are unaware of their developing habits while young, and become cognizant of them only on growing up. We show that an altruistic mother (i) maintains the amount of income transferred to her child lower...

In the theory of endogenous time preference, one of the most common and most controversial assumptions is that the degree of impatience, measured by the rate of time preference, is increasing in wealth. Although this empirically-unjustified assumption often helps ease dynamic analyses by...

Unlike the standard assumption that the degree of impatience, measured by the rate of time preference, is increasing in wealth, empirical studies support that impatience ismarginally decreasing. By introducing decreasing marginal impatience into the neoclassical monetary growth model á la...

Most studies have not distinguished delay from intervals, so that whether the declining impatience really holds has been an open question. We conducted an experiment that explicitly distinguishes them, and confirmed the declining impatience. This implies that people make dynamically inconsistent...

This paper investigates whether smokers exhibit greater time discounting than non-smokers, and how short-term nicotine deprivation affects time discounting. A unique feature of our experiment is that our subjects receive rewards not only of money, but also of actual tobacco. This is done in...

Analysis of an original, broad, internet-based survey reveals that debt holding is related to three aspects of time discounting: (i) present bias, measured by the degree of declining impatience in the generalized hyperbolic discount function; (ii) borrowing aversion, captured by a sign effect -...

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...

We formulate nominal wage adjustment by incorporating various concepts of fairness. By applying it into a continuous-time money-in-utility model we examine macroeconomic dynamics with and without a liquidity trap and obtain the condition for persistent unemployment, and that for temporary...
