Tests of the present-value model of the current account: a note

Using a Monte Carlo approach, we evaluate the small-sample properties of four different tests of the present-value model (PVM) of the current account: the non-linear Wald, linear Wald, Lagrange multiplier, and likelihood ratio tests. We find that the non-linear Wald test is biased towards over-rejecting the cross-equation restrictions implied by the PVM, and that the test statistic is uncorrelated with the goodness of fit of the PVM. The three alternative tests are essentially equivalent and
more » ... more reliable in evaluating the PVM. JEL classification: C15, F32, F41
