Empirical research has been conducted on the various theories of the business cycle over many countries. However, very little research has attempted to undertake a multi-country disaggregate investigation into the sources of output change. This paper decomposes fluctuations in industry output in a particular country into: (1) a nation specific shock; (2) an industry specific shock; (3) a world shock; and (4) an idiosyncratic factor. Using a dynamic factor analysis-state-space approach, the paper finds that the nation-specific shock is the most important impulse.
This paper looks at whether the aggregate ERM money supply has been a useful predictor of short-term changes in inflation and growth, and long-term trends in price levels among the core ERM countries. The evidence suggests that over the period since 1987, when there have been no realignments, the ERM money supply performs at least as well, and arguably better, than the individual national aggregates in predicting nominal aggregates such as inflation and the price level, while neither money supply is a good predictor of real activity.
