Youth unemployment in the OECD: demographic shifts, labour market institutions, and macroeconomic shocks

We use a panel of OECD countries to gauge the relevance of the relative size of the youth population, labour market institutions and macroeconomic shocks at explaining observed relative youth employement rates. We find that the fluctuations of the youth population size caused by the baby boom of the 1950s and 1960s and the subsequent decline of fertility in many European countries are positivily associated with fluctuations in relative youth unemployment rates. We also find that some labour market institutions contribute to increase yout unemployment, and that the adjustment to macroeconomic shocks has affected relatively more to young workers than to adult workers. To motivate the effects of institution on the relative unemployment rate of young workers, we lay out a simple theoretical model that builds on the imperfect substitutability of workers of different ages, and on the non-allocative role of (age specific) wages.
