A multivariate latent factor decomposition of international bond yield spreads
国际债券收益率利差的多变量潜在因子分解
Abstract A factor analysis of long‐term bond spreads is performed by decomposing international interest rate spreads into national and global factors. The factors are latent, and are assumed to have GARCH‐type specifications as well as exhibiting serial dependence. An indirect estimator is used to compute estimates of the unknown parameters. The sampling performance of this estimator is investigated and compared with an alternative direct estimator based on the Kalman…
