Yesterday, Boston Fed President Eric Rosengren filled the airwaves with talk about the FED to be more aggressive in raising rates in order to prevent wage inflation from curtailing the current expansion. The continued concern from Wall Street about the POSSIBILITY of wage inflation because of FULL EMPLOYMENT reflects on the flaws in central bank’s models. Nairu (non-accelerating inflation rate of unemployment) is so 1970s, when globalization was just beginning and private sector unions had genuine bargaining power. The end of the Cold War unleashed hundreds of millions of workers to compete with workers in the highly developed and advanced economies. The fall of the Berlin Wall pressured even the strong German unions as the fear of jobs moving to Eastern Europe resulted in Social Democrat Gerhard Schroeder initiating the Hartz IV labor reforms which resulted in stagnant wages in return for some job security.
