Abstract
By using a two-country model with endogenous time preference, this paper examines the dynamic implication of decreasing marginal impatience (DMI). To ensure stability, we assume that one country has DMI whereas the other has increasing marginal impatience (IMI). The resultant equilibrium dynamics differ from what can be inferred from the analysis of the standard IMI model (e.g., Devereux and Shi in J Int Econ 30:1–25, 1991). An increase in fiscal spending, in either country with DMI or IMI, has always contrasting long-run effects on domestic and foreign consumption and hence on domestic and foreign welfare; and the same policy definitely raises the interest rate in the long run.
