This paper extends the arbitrage pricing theory to an international setting. Specifying a linear factor return-generating model in local currency terms, the author shows that the usual risk-diversification rule in the arbitrage pricing theory does not yield a riskless portfolio unless currency...

We examine the current account effect of a terms-of-trade deterioration for a small country model, incorporating weakly non-separable preferences à la Shi (1994) under endogenous time preference. This enables us to emphasize a welfare change as an important determinant of the current account....

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...

Using a two-good, two-country model, we examine macroeconomic adjustment by allowing for decreasing and increasing marginal impatience (DMI and IMI). In the reference case where both countries have IMI, a negative output shock in one country lowers the interest rate and both countries' welfare...

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...

Using a multicountry model with perfect-foresight dynamic optimization by infinitely-lived households, the authors analyze the dynamics of macroeconomic nonmonetary and monetary variables. The authors show that the most patient country initially accumulates foreign debt but eventually...

ABSTRACT By using a panel survey of Japanese adults, we show that smoking behavior is associated with personal time discounting and its biases, such as hyperbolic discounting and the sign effect, in the way that theory predicts: smoking depends positively on the discount rate and the degree of...
