We review the I(2) model in an empirical perspective, and report the results of some Monte Carlo simulations on the small sample performance of asymptotic tests on the long-run coefficients in I(2) and near-I(2) systems. The results how that, although moderate size bias tend to be present in both cases, the I(2) model may provide a suitable tool for analysing near-I(2) systems.
