The study looked at how international uncertainty affects the economies of G7 countries. They used a special statistical method to analyze this called Bayesian vector autoregression with factor stochastic volatility. The results showed that when there is high international uncertainty, it has a big impact on the economies and financial markets of these countries. The researchers found that global equity price volatility is closely linked to this uncertainty measure, and that it affects a wide range of economic and financial variables in significant ways.
