Deconstructing the Success of Real Business Cycles
The empirical success of RBC models is often judged by their ability to explain the behavior of a multitude of real macroeconomic variables using a single exogenous shock process. This paper shows that in a model with the same basic structure as the bare bones RBC model, monetary, cost push or preference shocks are equally successful at explaining the behavior of macroeconomic variables. Thus, the empirical success of the RBC model with respect to standard RBC evaluation techniques arises from the basic form of the dynamic stochastic general equilibrium model; not from the specific role of the productivity shock.
