Gross domestic product, or GDP, is the one statistic that almost everyone knows is used to measure economic growth. But in this podcast, economist Diane Coyle suggests GDP may be a poor measure of prosperity. With all the technological advances in recent years one would expect that economies have become more productive. But when measured in GDP the numbers show the opposite is true. Coyle refers to this phenomenon as the productivity puzzle, and says the mismeasurement of digital activities within the economy has a lot to do with it. Coyle is Professor of Economics at the University of Manchester, and spoke at the IMF Statistical forum on Measuring the Digital Economy.
