The dynamic effects of shocks to labour markets: evidence from OECD countries

This paper uses a set of plausible long-run identifying restrictionson a three-variable system, including output growth, real wagegrowth, and the unemployment rate, to isolate three independentstructural shocks which drive fluctuations in those variablesin a sample of 16 OECD countries during 1950-96. These shocksare interpreted as aggregate demand, productivity, and laboursupply disturbances. As a by-product of the previous analysis,the cyclical behaviour of real wages in response to a demandshock is re-examined and two indices of real wage rigidity arederived.
