Increased LFP by older workers has nearly doubled, leading to a significant labor supply shock, suppressing wage growth & contributing to lower inflation, according to @BenoitMojon @Bank_for_International_Settlements.
"...First, we observe major adjustments of labor supply in response to the ageing of the population. In this respect, the persistent call of central banks for reforms has been either anticipated or answered to by politicians, labor market institutions, employers and workers. This increase in participation implies that potential output should have increased. If the participation of 20% of the working population (population aged 55 to 64 over population aged 20 to 64) has nearly doubled, it means that aggregate output potential should increase as well. It would increase by roughly 10% if the productivity of older worker grows in line with the one of other workers. It should increase by less than 10% if the productivity of older workers is slower. It will in any case grow as long as the productivity growth of these older workers is not too negative.... wages have responded negatively to increased participation of older workers. Therefore, the change in the composition of the workforce is akin to a major labor supply shock by ageing workers. Most likely these aim to preserve their lifetime purchasing power through postponing their retirement....Second, (wage) inflation remains very much driven by cyclical forces and therefore it can be influenced by monetary policies. This result should be taken into account by those who fear that the “Phillips curve” transmission of monetary policy to inflation is broken. Central banks who spur activity and employment will eventually harvest domestic wage inflation, and, in all likelihood, inflation of goods and services. Third, it is not clear yet how high participation rates of older workers will go. We are probablundergoing a very long transition and we don’t know when it will end. But as long as this transition implies a larger slack than measured by the unemployment rate, the economy operates below its "NAIRU" potential. Taking a broader perspective, it seems that unemployement has not been a comprehensive indicator of labor market slack...."
