Global Gross Domestic Product (GDP) growth has stagnated since the financial crisis in 2008, and here in the U.S. this economic recovery has been the slowest since World War II. GDP growth in the United States has averaged just 2.1% since the beginning of 2009, well below the 3.2% average over the past 70 years. Potential reasons for this slow growth are numerous; debt deleveraging, low capital spending by corporations, central bank market manipulation, etc. While the list of potential reasons is lengthy, perhaps we should also include the possibility that we’re no longer measuring GDP correctly. Today’s recommended reading comes to us from the blog of Timothy Taylor, Managing Editor of the Journal of Economic Perspectives. Timothy’s article discusses some of the challenges of properly measuring GDP growth as it relates to the digital economy, along with other challenges such as the proper measurement of inflation and the valuation of digital assets. To Timothy’s point, just last month game publisher Supercell sold a majority stake in its business for $8.6 billion, which is quite a haul given that the company’s games can be downloaded for free.
