Testing the Lucas Hypothesis on Output-Inflation Trade-offs
检验产出与通胀权衡中的卢卡斯假说
A Bayesian highest-posterior interval test that accounts for heteroscedasticity and for two regimes of autocorrelation is derived to test the Lucas variance hypothesis on output-inflation trade-offs. Japanese and U.S. data show that heteroscedasticity and autocorrelation tend to influence the test results. A Bayesian procedure and Akaike's information criterion are used to determine the order or autoregressive schemes, and a join point to partition the sample is estimated by…
