This paper investigates whether consumer durables are important for the generation and propagation of business cycles. The author constructs a two-sector model that succeeds in generating business cycles that mimic empirical patterns of cross-sector volatility and comovement. She finds that half the relatively higher volatility associated with the durable-goods sector is due to higher volatility of shocks hitting this sector, with the other half due to endogenous responses, notably the investment accelerator. Nevertheless, this model does not have stronger internal propagation than the one-sector model. Further, incorporating durable consumer goods has little effect on the behavior of other macroeconomic variables.

Band-pass filters are useful in a wide range of economic contexts. This paper develops a set of approximate band-pass filters and illustrates their application to measuring the business-cycle component of macroeconomic activity. Detailed comparisons are made with several alternative filters commonly used for extracting business-cycle components.
