Are there estimates of monthly real GDP?
Yes. Macroeconomic Advisers, a consulting firm, prepares estimates of monthly real GDP. Many of the ingredients of the quarterly GDP figures are published at a monthly frequency by the Bureau of Economic Analysis. Macroeconomic Advisers aggregates them, and then uses a statistical procedure to adjust the monthly estimates for each quarter to make them consistent with the Commerce Department’s official quarterly figure. The monthly GDP numbers are fairly noisy and are subject to considerable revision. Estimated monthly real GDP reached one peak in January 2008 and another, higher peak in June 2008.
