This paper resolves the sectoral comovement problem between nondurable and durable outputs that arises in response to a monetary shock in a two-sector sticky price model with flexibly priced durable goods. We analytically demonstrate that the non-separability between aggregate consumption and labor can generate the comovement between nondurable and durable outputs in response to a monetary policy shock. We then estimate the degree of non-separability, together with other parameters, using a Bayesian approach. We find that the non-separable preferences are supported by the data and our estimated model generates the sectoral comovement in response to a monetary shock.
