initial values matter, convergence is best measured in terms of σ-convergence over a fixed time period. For this setting, we … propose a new simple Wald test for conditional σ-convergence. According to our Monte Carlo simulations, this test performs … well and its power is comparable with the available tests of unconditional convergence. We apply two versions of the test …
