This paper is a sequel to Working Paper No. 3131, quot;Hypotheses of Sticky Wages and Pricesquot;. My first objective is to re-examine the historical record of prices and wages. What changes in their behavior are indicated by the data and how can they be explained? Next, the models that imply...

In the post-World War II period, wage and price levels reacted much less to business contractions than they did in earlier times. Inflation prevailed and its persistence increased. The contractions themselves became relatively short and mild. All these developments have some common roots in the...

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...

The aim of this study is to contribute to the measurement and analysis of errors in economists' predictions of changes in aggregate income, output, and the price level. Small sample studies of forecasts can be instructive, but their limitations must be recognized. Compilation of consistent...

This survey outlines the evolution of thought leading to the rrecent delopments in the study of business cycles.The subject is almost coextensive with short-term macrodynamics and has a large interface withmeconomics of growth, money, inflation, and expectations.The coverage is therefore both...

The answer to this question depends on the treatment of logically and empirically prior questions about (1) what the forecasts are and why they are needed, and (2) what can reasonably be expected of them. Further, what forecasters can and should do cannot be established without studying the...

This paper considers the question in its title from several angles. Part 1 looks at economic history and the development of thinking about business cycles - the popular meaning and economists' definitions and ideas. Part 2 reviews the lessons from business cycle chronologies and duration data,...

This paper reports on a comprehensive study of the distributions of summary measures of error for a large collection of quarterly multiperiod predictions of six variables representing inflation, real qrowth, unemployment,and percentage changes in nominal GNP and two of its more volatile...

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...
