Implict Estimates of the Natural and Cyclical Components of Japan's Real GNP
Charles R. Nelson
This paper studies measurement of the business cycle from an economic rather than purely statistical perspective. Since the natural level of output is associated with price stability it should be possible to infer its behavior from relative movements of inflation and output, given a model of price dynamics. For example, if inflation accelerates when output slows it seems clear that the natural level has declined. While long-term growth is due to the natural level, short-term fluctuations will be generated by both nominal demand shocks and real shocks to the natural level. Results for Japan's real GNP are presented.
