This article aims to compare the National Institute's forecasting performance with that of United States forecasters. Because of the magnitude of this task, we restrict our attention to forecasts of the principal output measure in each country—real gross domestic product in the United Kingdom and real gross national product in the United States. Results for US forecasters are taken from the detailed study by McNees (1975), where there is also information on the methods employed by these forecasters.
