The study looked at how U.S. economic shocks affect the global economy using a special statistical model. They found that U.S. shocks have a big impact on other countries, especially when it comes to changes in U.S. monetary policy. Different types of shocks have different effects on other countries, with some causing short-term changes and others leading to long-lasting impacts. The U.S. plays a big role in shaping global financial markets, with interest rates being a key way that U.S. shocks spread around the world. Other important ways that U.S. shocks affect other countries include changes in oil prices and how economies move together.
