Lawrence Klein won the Nobel Prize in Economics for his original work in developing modelsOne of the most important, and visible, things economists do is to forecast what will happen in the economy in the future. Each year a number of different groups in the US use their own econometric models to forecast what will happen to the economy in the coming year. Some forecasts are more accurate than others.This book consists of chapters by distinguished economists comparing the different models now being used. It is organized topically rather than by model. The contributors include: Roger Brimmer, Ray Fair, Bert Hickman, F. Gerard Adams, and Albert Ando. Lawrence Klein provides an introduction to the volume.
