Comparing Real GDP Across Countries: Comment. Lawrence Summers, June 24, 2016, Opinion. "The author discusses British economist David Henderson's article for "Economic Affairs" on using gross domestic product (GDP) measures based on purchasing power parity (PPP) to compare GDP across countries. Topics covered include the relevance of exchange rates in making international economic assessments, Henderson's criticism of the use of exchange rate-based GDP growth forecasts, and reasons why real international accounts deserve a more prominent place in economic statistics."
