A national media organisation (Crikey) invited me to be one of their Fantasy Budget providers this year and this is a background blog to the preparation of my Fantasy Budget 2013-14 for Australia, which I will publish next Monday. In this blog I consider the state of the Australian economy in terms of output gaps. The Australian government is keen to claim that the economy is operating close to or at trend real output – sometimes the Prime Minister or Treasurer – and senior Treasury officials, will replace the descriptor “trend output” with “full employment”. They make that claim to justify imposing fiscal austerity on the economy, which is expressed by their most recent goal to achieve a budget surplus in the current year. They have been pursuing that strategy for several budgets now after taking appropriate steps in 2008 to allow the budget deficit to rise significantly to head off the looming disaster associated with the global financial crisis. While the stimulus was not large enough at the time it did save the economy from the type of chronic recession that most of the advanced world remains stuck in. But, once recovery was established, the conservative ideology returned and the fiscal stimulus was withdrawn too quickly and an austerity plan implemented. At the time, it was clear that they would fail to achieve a surplus because in attempting to do so they undermined the recovery, and, their tax revenue growth. Other international events (a slowing of the terms of trade and an overvalued dollar) have compounded their poorly crafted fiscal strategy. The reality is that the Australian economy is now performing well below trend and the divergence is increasing. The labour market is also producing grossly inferior outcomes and we are clearly a hundreds of thousands of jobs short of what a reasonable definition of full employment would require. The budget deficit is too small not too large and the direction of policy in the coming year should be expansionary not contractionary.
