For partly nonstationary dynamic panel models whose component series are threshold autoregressive processes having possibly unit roots, an instrumental variable method is applied to construct a Wald test and a t-bar type test whose limiting null distributions converge to a chi-square distribution and the standard normal distribution, respectively, as component series length increases to infinity. Finite sample sizes and powers of the proposed tests are investigated by a Monte Carlo simulation.
