This paper is a sequel to Working Paper No. 3131, "Hypotheses of Sticky Wages and Prices". 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 that price...

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...

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...

Each quarter since 1968 the National Bureau of Economic Research, in collaboration with the American Statistical Association, has been collecting a large amount of information on the record of forecasting in the U. S. economy. This paper is a progress report on a comprehensive study of the...

What is the role of foresight, and the significance of the lack of foresight under uncertainty, in the theory of business cycles ? What relevant evidence on these questions can be extracted from the survey data on agents' expectations and experts' forecasts? To provide some answers, the recent...

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...

Various structural, institutional, and policy changes have contributed to the evolution of business cycles, since World War II business expansions have been much longer and contractions much shorter than before. Over nearly 200 years of U.S. history expansions have been long relative to...

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,...
