We hear a lot about wages these days. Fresh union wage demands, waiters on $40 an hour on public holidays, and how much money some lucky people are earning up north on the mines, sometimes with no formal qualifications (why’d I bother going to uni?). While it may not feel like it for everyone, we live in one of the luckiest parts of the world right now in Western Australia. The latest ABS estimates are that the seasonally adjusted unemployment rate was 4.3% in November 2011, and average weekly ordinary time earnings grew by 11.3% over the year to August – by far the highest of any state, and compared with the national average of 5.3% growth.
So, how and why is this happening? And is it sustainable? Well, the obvious answer to the first question would be high resource prices, and I won’t argue with that. The answer to the second question is a little less clear, however. In the long run, wages growth demands high productivity. So, how productive is WA?
The simplest measure of productivity is Gross Domestic Product (or Gross State Product, in this case) per capita. That is the total output of the economy, divided by the number of people. On this measure, WA’s productivity is pretty good. Higher than all of the states (although lower than the ACT), and roughly comparable to Switzerland, according to this interesting little Wikipedia article:

I find the comparison with Switzerland quite interesting because Switzerland is one of the few places in the world with even less reasonable prices than Perth.* The staggering thing about the figures is that WA’s GSP per capita, at $80,858 per person is more than a third bigger than the national average.
The ABS also publishes estimates of the aggregate hours worked in each state. Using this data, we can calculate GSP per hour worked. This is arguably a better measure of labour productivity, as it adjusts for differences in the labour force participation rate and the number of hours people are working. On this measure, WA comes out as the leader of the pack, due to the unusually high participation rate in the ACT, as the centre of the federal public service. The news is not all rosy though. Growth in GSP per hour worked has been a bit patchy over the past few years, and in fact there was a fall in 2010-11 (see chart below). And this is at the same time as wages increased by 11.3%.

So, what of the future? In the long run, growth in wages requires growth in productivity. However, our growth in real output per hour worked has been patchy, while wages have increased substantially, because of the resources boom. How do we improve on our productivity?
