Puzzling Global Stochastic Trends in Growth, Interest and Inflation and the Volcker Disinflation

This paper aims to identify the stable long?run relationships as well as unstable driving forces of the world economy using a small aggregated cointegrated VAR model encompassing quarterly US, UK, Japanese and Euro Area data for the post?Bretton?Woods era. Three stable long?run relationships are found: output growth, the term spread and the inflation climate. The common stochastic trend of the global macro economy is dominated by the cumulated real short?term interest rate shocks, reflecting the strong increase of global real rates during the Volcker disinflation period, one of the dominating events of the last 40 years of macro history.
