This paper presents extensive results from testing for bias and serially correlated errors in a large collection of quarterly multiperiod predictions from surveys conducted since 1968 by the National Bureau of Economic Research and the American Statistical Association. The tests of the joint...

This paper examines the flow of production and use of economic information and analyzes the effects of measurement errors, particularly as transmitted through expectations and forecasts. Economic data are subject to a variety of errors, and the uncertainty about economic measures tends to...

The composite index of leading indicators is found to be a valuable tool for predicting not only the direction but also the size of near- term changes in aggregate economic activity. This conclusion is based on assessments of the leading index as a predictor of (1) business cycle turning points...

The flow of production and use of economic information consists of the collection and processing of primary data, the reporting of the resulting measures, and the transformation of the latter into signals or messages that presumably aid knowledge or decision-making. Each stage contributes to the...

Few business cycle peaks are successfully predicted; indeed, most are publicly recognized only with lengty delays. Analysts...

Have macroeconomic forecasts grown more or less accurate over time? This paper assembles, examines, and interprets evidence bearing on this question. Contrary to some critics, there are no indications that U.S. forecasts have grown systematically worse, that is, less accurate, more biased, or...

This paper represents a very early progress report on a new study of business cycle indicators for the United States. Our host organization, CIRET, is concerned with research on surveys of economic tendencies that cover broad areas of business, investment, and consumer behavior. These inquiries...

The National Bureau of Economic Research, in co-operation with the American Statistical Association, conducted a regular quarterly survey of professional macroeconomic forecasters for 22 years beginning in 1968. The survey produced a mass of information about characteristics and results of the...

Is the long-term trend of the economy -- growth -- substantially influenced by the short-term movements -- business cycles -- and, if so, how? Are business cycles subject to major secular changes? Are these fluctuations the natural way growth takes in private enterprise economies or are they...
