Stochastic Growth and Factor Income Risk


  • Christiane Clemens


This paper examines the effects of aggregate factor income risk in a tractable version of the stochastic Romer endogenous growth model. Labor supply is endogenous. The presence of labor income risk unambiguously increases savings and growth due to precautionary motives. Households not only underaccumulate but also work less along the balanced growth path of the competitive economy when compared with the Pareto-efficient allocation. The paper also discusses distributive disturbances for the case of inelastic labor supply. Here, growth effects are negative for empirically plausible correlations of the underlying shocks.
