Digitally disrupted GDP (Diane Coyle, VoxEU CEPR)

Digital technologies are having dramatic impacts on consumers, businesses, and markets. These developments have reignited the debate over the definition and measurement of common economic statistics such as GDP. This column examines the measurement challenges posed by digital innovation on the economic landscape. It shows how existing approaches are unable to capture certain elements of the consumer surplus created by digital innovation. It further demonstrates how they can misrepresent market-level shifts, leading to false assessments of production and growth.
