New research reveals international impact of long-term interest rates on economies
The article defines long-run causality as one variable influencing another over time. By analyzing US, German, and French long-term interest rates from 1990 to 1997, the researchers found that past knowledge of one country's rates can help predict another's in the long term. They used a statistical method to test for these causal links, showing that certain interest rates are connected in the long run.
