We assess time-variation in labor productivity growth for a broad set of OECD countries over the period 1960–2016. The analysis utilizes a quarterly dataset and takes full account of the intensive labor margin. We apply ‘data-hungry’ endogenous break tests and time-varying parameters median-unbiased estimation. While the decline in labor productivity growth is particularly striking for European countries and Japan, it is rather mild in Anglo-Saxon economies.
