Real-business-cycle models rely on total factor productivity (TFP) shocks to explain the observed co-movement among consumption, investment and hours. However an emerging body of evidence identifies “investment shocks” as important drivers of business cycles. This paper shows that a neoclassical model consistent with observed heterogeneity in labor supply and consumption across employed and non-employed can generate co-movement in response non-TFP shocks. Estimation reveals fluctuations in the marginal efficiency of investment that explain the bulk of business-cycle variance in consumption, investment and hours. A corollary of the model׳s empirical success is the labor wedge that is not important at business-cycle frequencies.
