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...

By combining our broad panel survey of Japanese adults from 2005 to 2008 and actual cigarette tax data, we investigate how smoking behavior including responses to tax hikes depends on time discounting and its biases, such as hyperbolic discounting and the sign effect. Cigarette consumption...

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...

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...

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...
