Testing structural stability with endogenous breakpoint A size comparison of analytic and bootstrap procedures
断点内生选择下的结构稳定性检验:解析与自助法的尺寸比较
We compare the performance of two alternative approximations to the finite-sample distributions of test statistics for structural change, one based on asymptotics and one based on the bootstrap. We focus on tests acknowledging that the breakpoint is selected endogenously — in particular, the ‘supremum’ tests of Andrews (1993). We explore a variety of issues of interest in applied work, focusing particularly on smaller samples and persistent dynamics. The bootstrap…
