Identifying the sources of the slowdown in growth: Demand vs. supply

Nicolò Maffei-Faccioli
Working Paper


Long-run GDP growth has declined in the United States over the past two decades. Two competing views take the stage in accounting for this slowdown: demand-side and supply-side. I empirically quantify their relative importance in a Bayesian SVAR with common trends, identified using sign restrictions based on the co-movement of prices and quantities. While supply-side factors were the main driver of long-run GDP growth prior to 2000, demand-side factors explain half of its slowdown afterwards. The findings suggest a relevant role of demand forces as drivers of long-run growth.

Norges Bank’s Working Papers present research projects and reports that are generally not in their final form. Other analyses by Norges Bank’s economists are also included in the series. The views and conclusions in these documents are those of the authors.
