The Present Value Model and New Zealand’s current account
This paper tests the present value model of the current account on New Zealand data. There is some evidence in favour of the PVM – the current account tests as stationary and Granger-causes changes in national net income. However, the cross-equation restrictions implied by the model are rejected both individually and jointly. This result holds for both the linear and non-linear versions of the tests. The orthogonality test results are consistent with rejection due to the presence of a transitory demand shock. We conclude that a richer model is needed to understand current account dynamics.
