Following my earlier discussion of relative economic performance in Australia and NZ, I’ve been chatting with people in the NZ Treasury, and also with some of the macroeconomists in my own department. Its given me a number of research ideas I hope to pursue in the future, both with respect to possible ways the NZ-Oz gap might be bridged and more general implications about macroeconomic theory.
In the circumstances of the election what matters is the suggestion by Tony Abbott and others on the political right that New Zealand is a model for Australia to follow as regards macroeconomic policy. The key point is that NZ had a smaller stimulus than we did, and looks set to return to surplus a little earlier, though of course we know how unreliable such projections can be.
If, like Abbott, Hockey and (on even-numbered days) Robb, you regard budget surpluses as the paramount measure of good economic performance, there’s a case to be made here. But if you think that employment and economic growth are more important, Australia looks a whole lot better, as you can see from the graphs below.
Standard economic theory suggests that, when two countries have access to the same technology, comparable education systems, free labour and capital movements and so on, any initial differences in income levels should gradually be evened out. Instead, the Oz-NZ gap has widened since the GFC. Anyone who could seriously suggest NZ as an economic model should not be entrusted with the management of our economy.
