We examine the driving forces of G-7 business cycles. We decompose national business cycles into common and nation-specific components using a dynamic factor model. We also do this for driving variables found in business cycle models: productivity; measures of fiscal and monetary policy; the terms of trade and oil prices. We find a large common factor in oil prices, productivity, and the terms of trade. Productivity is the main driving force, with other drivers isolated to particular nations or sub-periods. Along these lines, we document shifts in the correlation of the common component of each driver with the overall G-7 cycle. (Copyright: Elsevier)
