In this article, we provide an overview of the key mechanisms by which sectoral disturbances affect aggregate economic activity. We describe how the distribution of sectoral shares influences each sector's contribution to the variation in aggregate output. We also illustrate different aspects of...

Using a factor analytic framework, we show that employment variations differ significantly across sectors. In some sectors, notably in goods production, employment movements are driven almost entirely by aggregate shocks. Because aggregate shocks drive business cycles (i.e., sector-specific...
