Macroeconomic synchronization between g3 countries

Zusammenfassung

This paper studies the existence of a world business cycle by examining quarterly and annual comovements in production, prices, and interest rates in the three main world economies: Germany, Japan and the U.S. In accordance with earlier studies, contemporaneous relationships clearly dominate short-term dynamics. The evidence indicates that, in the last four decades, these comovements are clearly significant in all the variables, with the possible exception of short-term interest rates, and they are stronger for long-term interest rates; nevertheless, they are rather unstable over time.
