Abstract
We show that the preferences suggested by Greenwood, Hercowitz and Huffman (GHH), which are quite common in real business cycle (RBC) models of small open economies, are not suited for reproducing both the business cycle and the equity premium facts of a small open economy. We show that by assuming a moderate degree of a wealth effect on labor supply, together with some limitations on labor supply (in the form of real wage rigidity), we can increase the volatility of the stochastic discount factor (SDF), thereby increasing the equity premium and improving the fit of the business cycle moments. We also find that under the aforementioned assumptions, a shock to the realized return on foreign bonds can help in reproducing the equity premium.
