 have called this property the 'divine coincidence', and have argued that in more realistic models which include additional frictions, it no longer holds. Instead, models with additional frictions (such as frictional unemployment) imply a tradeoff between stabilizing inflation and stabilizing the output gap.

Galí is perhaps best known for providing time series evidence that improvements in labour productivity cause employment to decrease. This finding contradicts the predictions of some well-known real business cycle models promoted by the New Classical macroeconomic school, but is (according to Galí) consistent with many New Keynesian models. However, the statistical methods ('structural vector autoregressions') on which this finding is based remain controversial.
