This paper develops a method to analyze large cross-sections with non-trivial time dimension.The method (i) identifies the number of common shocks in a factor analytic model; (ii) estimates the unobserved common dynamic component; (iii) shows how to test for fundamentalness of the common shocks; (iv) quantifies negative and positive comovements at each frequency. We illustrate how the prposed techniques can be used for analyzing features of the business cycle and economic growth.
