This paper examines the dynamic implications of the use of an endogenous discount factor in small open economy models. We first present a stochastic dynamic model of a small open economy with an endogenous discount factor. Then, we examine the same model with a fixed discount factor. We...

This paper investigates the accuracy of the log-linear approximation method in welfare calculations, especially in measuring welfare gains of international risk sharing. We derive closed-form solutions for a two-country complete market economy using log-linearization and a nonlinear solution...

Most general equilibrium models calculate welfare gains from international risk sharing based on a loglinear approximation. They have reported welfare gains ranging from zero to one percent of permanent consumption. Some simulation results -- Tesar (1995), van Wincoop (1997), and Kim (1997) --...

We examine the importance of world real interest rate shocks in explaining business-cycle fluctuations in open economies using a stochastic dynamic model of a small open economy. We argue that a good proxy of the world real interest rate is not available. Moreover, the world interest rate...
