Abstract
Using a dynamic factor model that allows for changes in both the longrun growth rate of output and the volatility of business cycles, we document a significant decline in long-run output growth in the United States. Our evidence supports the view that most of this slowdown occurred prior to the Great Recession. We show how to use the model to decompose changes in long-run growth into its underlying drivers. At low frequencies, a decline in the growth rate of labor productivity appears to be behind the recent slowdown in GDP growth for both the US and other advanced economies. When applied to realtime data, the proposed model is capable of detecting shifts in long-run growth in a timely and reliable manner.
