I was going to write about military expenditure today in the light of large cuts to defense spending that the Australian government made in last week’s Budget and the decision by the Obama Administration to make it easier for American firms to export military equipment (to who knows where!). The concept of the military-industrial complex is interesting and, to some extent, the issues that are being raised by the US decision were discussed during the Great Depression (I have been reading a lot of material from the 1930s lately). While some might (from a micro perspective) conclude that reducing spending on the military is a good thing (less violence etc) they also have to be mindful of the macro perspective which considers a $ spend on a tank to be equivalent in its impact on aggregate demand as a $ spent on public education – well nearly. But I will write about that tomorrow. There were two interesting interventions into the public debate in Australia yesterday from the current Treasury boss and the recently departed Treasury boss which have general application everywhere. While they are current I thought I would consider these general points today.
