摘要
The world interest rate is a key determinant of borrowing and lending behavior and plays a central role in most open-economy macro models. This paper uses a dynamic factor model to construct a world interest rate based on short run interest rates of over 70 countries. Compared to simple averages, such a process should better extract a common trend, rather than be influenced by idiosyncratic shocks. In a simple econometric model, the global rate can be dominated by whatever region has the most countries in the sample. With regional factors incorporated, the obtained global factor can reflect overall global influences. Consistent with recent evidence, we find the global rate is on a long run secular downward trend. Furthermore, capital account openness strongly affects both the co-movements of local-regional and local-world rates. Finally, we also make methodological suggestions for the practical use of dynamic factor models especially when the proper regional groupings are not obvious.
