Does the digital economy distort price and volume measures of GDP?

The slowdown in economic growth over the last twenty years contrasts with the digitization of the economy. As a result, some economists are wondering about a possible problem of measuring GDP and especially its volume and price measures. The article presents the methods used by statisticians to distinguish price changes from volume changes, focusing on the particularities and challenges of the digital economy: communication goods and services, the existence of digital sales forms, the emergence of new services, the development of free services. If the usual methods deserve to be questioned, a simulation shows that an error in the price measure of information and communication products is not likely to explain the slowdown in economic growth.
