“…Our econometric methods will also use DFMs. DFMs have become an increasingly common way of quantifying the extent of co-movements in macroeconomic variables (e.g., among others, Otrok and Whiteman, 1998;Kose, Otrok and Whiteman, 2003;Crucini, Kose and Otork, 2011;Mumtaz, Simonelli and Surico, 2011) and …nancial time series (e.g., among others, Aguilar and West, 2000;Gourieroux and Jasiak, 2001;Diebold, Rudebusch and Aruoba, 2006;and, Koopman, Lucas and Schwaab, 2012). In our setting, DFMs can quantify the degree of co-movement in employment growth across industries and regions and allow us to determine the sources of ‡uctuations in employment growth, i.e., how much of the ‡uctuations in employment growth can be attributed to industry factors, regional factors, national factors or external factors.…”
