Estimating structural and frictional unemployment: An application of empirical mode decomposition

Authorship SCIMAGO INSTITUTIONS RANKINGS

The aim of this paper was to estimate Brazilian structural and frictional unemployment by the empirical mode decomposition (EMD) method, relying on the definitions of structural and frictional unemployment of Lipsey (1960)Lipsey, R. G. (1960): “The relation between unemployment and the rate of change of money wage rates in the United Kingdom, 1862-1957: A further analysis,” Economica, 27, 1-31. [1, 2, 6]. The advantage of the EMD method is that it does not suffer of the problems of approximation bias or unit root that are present in the OLS and ML estimates described in the literature.
