The Real Term Premium in a Stationary Economy with Segmented Asset Markets

Abstract: This paper proposes an equilibrium model to explain the positive and sizable term premia observed in the data. We introduce a slow mean-reverting process of consumption growth and a segmented asset market mechanism with heterogeneous trading technology to otherwise a standard heterogeneous agent general equilibrium model. First, a slow mean-reverting consumption growth process implies that the expected consumption growth rate is only slightly countercyclical and the process can exhibit a near zero first-order autocorrelation as seen in the data. The very small countercyclicality of the expected consumption growth rate suggests that the long term bonds are risky and hence the term premia are positive. Second, the segmented asset market mechanism amplifies the size and the magnitude of term premia since the aggregate risk is concentrated into a small fraction of marginal traders who demand high risk premia. For sensitivity analysis, the role of each assumption is further investigated by taking each factor out one by one.
