In a recent paper, Owen Lamont finds that forecasters in the Business Week survey make more radical forecasts as they gain experience. In this paper, the author uses forecasts from the Federal Reserve Bank of Philadelphia's Survey of Professional Forecasters to test the robustness of Lamont's results.

However, careful examination of a methodological difference in the two surveys suggests a more general theory of forecasting that accounts for both sets of results.
