New Indicators for Tracking Growth in Real Time

Matheson, Troy - International Monetary Fund (IMF) - 2011

We develop monthly indicators for tracking growth in 32 advanced and emerging-market economies. We test the historical performance of our indicators and find that they do a good job at describing the business cycle. In a recursive out-of-sample forecasting exercise, we find that the indicators...
