We decompose the underlying disturbances in total hours into three kinds: disturbances that shift the level of employment in the long run, those that change the sectoral composition of employment in the long run, and those that cause temporary movement of hours. Our identifying restriction exploits the distinctive nature of the two margins of labor: employment and hours per worker. Based on the postwar U.S. data, we find that aggregate and sectoral disturbances are roughly equally important for the cyclical fluctuations of aggregate hours.
