This is the second of a three-part series examining the comovement of business cycles among countries. Today’s post will look at how similar characteristics among countries matter for business cycle synchronization.
Our previous blog post, based on a recent article in The Regional Economist,1 discussed three components of a country’s business cycle:
Previous research showed that the regional component explained only a small percentage of business cycle fluctuations. However, more recently, researchers found that the regional component’s influence on a country’s business cycle depends on how regions are defined.
A 2003 study found that the global and country components explained a substantial portion of the cyclical movements for most countries, while regional components explained far less.2 As an example, the regional component for (pre-European Union) Europe explained only 2 percent of the variation in the three economic variables examined (output growth, consumption growth and investment growth).
However, this study defined regions by geographical proximity only. A 2012 study used regions based on country-specific factors, such as the degree of economic openness to trade, the investment share of real gross domestic product, the method of conflict resolution, the legal system, language, and composition of trade and production.3
These new regions resulted in three groups:
The authors of The Regional Economist article noted that, “Regions defined in this manner increase the share of output growth fluctuations attributable to the regional component, raising its importance relative to the global and country-specific components.”
When defining regions by location, the regional component explained just over 2 percent of the fluctuations in output growth. In contrast, these new regional components explained over 22 percent. The authors wrote, “This dramatic increase in the significance of the regional component indicates that the importance of the regional factor may be misrepresented when countries are sorted into purely geographic regions.”
Other factors may also be playing increasing roles in the links among countries’ business cycles. In particular, regional linkages and trade agreements have increased substantially. The authors noted, “If trade and financial flows across countries are becoming increasingly regional, the regional component may also find a rise in importance.” The final blog post in this series will examine whether economic linkages are becoming increasingly global or increasingly regional.
