Examining Sectoral Co-Movement in Estimated Nominal Rigidities Models
Recently, Barsky et al. (2007) found that a sticky-price model does not generate sectoral co-movement and that the propagation mechanism is weak in response to monetary shocks if prices in the durable goods sector are significantly flexible, which raises a co-movement problem in sticky-price models. In this paper, we estimate sticky-price models with both durable and nondurable goods sectors in order to examine sectoral price stickiness and co-movement using actual data. The estimation results show that prices in both sectors are relatively sticky and the co-movement problem does not occur in the usual settings. We find, however, that the co-movement problem may occur when we introduce persistent price-markup shocks in a sticky-price model. We also estimate nominal rigidities models with sticky wages as well as sticky prices and find that sticky wages are helpful in explaining sectoral co-movement in addition to sticky prices.
