This paper considers contributions of industry-sectoral-micro shocks vs aggregate macro shocks. A dynamic factor model is estimated with maximum likelihood method in the frequency domain, and decomposes US unemployment movements into industry sectoral and common components. Sectoral shocks...

We consider the contribution of sectoral shocks to post-war US unemployment movements in a dynamic factor framework. Whereas previously published estimates of the contribution of sectoral shocks to unemployment relate to a particular theory of unemployment, our approach is sufficiently general...

In this paper dynamic factor analysis techniques are used to decompose changes in unemployment into industry sectoral and common components. Sectoral shocks are important, but the dominant causes of variation in unemployment are common to all industries. This is particularly the case for...
