The Unassuming Economist

From a paper by Domingo Rodríguez Benavides, Nancy Muller Durán, and Ignacio Perrotini Hernández:

“The relationship between fluctuations of the unemployment rate and the growth rate of output (Okun’s Law) in Mexico, the United States (US) and Canada during the period 2006-2019 is dealt with in the present paper. We posit the hypothesis that cyclical shocks can permanently affect structural unemployment. A non-linear autorregresive distributive lag (NARDL) model is displayed to test the assumption of symmetric effects in Okun´s Law analysis. Our econometric results suggest that while in the US and Canada there is evidence of an asymmetric Okun’s Law in the short run and the long-term, respectively, for the case of Mexico no such evidence exists. These discrepancies speak to the relevance of looking at the existence of non- linear effects in Okun´s Law. The accurate identification of such effects can shed light for both labour market reforms and stabilization policy design.”
