The Productivity Slowdown in Advanced Economies: Common Shocks or Common Trends?

Abstract
This paper reviews advanced-economy productivity developments in recent decades. We focus primarily on the facts about, and explanations for, the mid-2000s labor-productivity slowdown in large European countries and the United States. Slower total factor productivity (TFP) growth was the proximate cause of the slowdown. This conclusion is robust to measurement challenges including the role of intangible assets, rankings of productivity levels, and data revisions. We contrast two main narratives for the stagnating TFP frontier: The shock of the Global Financial Crisis; and a common slowdown in TFP trends. Distinguishing these two empirically is hard, but the pre-recession timing of the U.S. slowdown suggests an important role for the common-trend explanation. We also discuss the unusual pattern of labor productivity growth since the start of the Covid-19 pandemic. Although it is early, there is little evidence so far that the large pandemic shock has changed the slow pre-pandemic trajectory of labor-productivity growth.

Productivity during and after the pandemic

Abstract
This paper reviews how productivity has evolved around the world since the pandemic began in 2020. Productivity in many countries has been volatile. We conclude that the broad contours of productivity growth during this period have been heavily shaped by predictable cyclical patterns. Looking at U.S. industry data, we find little evidence that the sharp rise in telework has had a notable impact, good or bad, on productivity. Stepping back, the data so far appear consistent with a continuation of the slow-productivity-growth trajectory that we faced before the pandemic.
