This paper studies the implications of internal consumption habit for propagation and monetary transmission in New Keynesian Dynamic Stochastic General Equilibrium (NKDSGE) models. The authors use Bayesian methods to evaluate the role of internal consumption habit in NKDSGE model propagation and monetary transmission. Simulation experiments show that internal consumption habit often improves NKDSGE model fit to output and consumption growth spectra by dampening business cycle periodicity. Nonetheless, habit NKDSGE model fit is vulnerable to nominal rigidity, the choice of monetary policy rule, the frequencies used for evaluation, and spectra identified by permanent productivity shocks.
