What we earn

Since the 'do nothing' policy approach doesn't seem to be working, what could be done to turn the situation around? Basically, it's a simple formula between incomes and prices. You either increase incomes or reduce prices. The first probably isn't an option unless incomes can gradually creep up with inflation and with productivity gains over time.

But what could also happen is the cost of supplying new housing (not referring to existing stock) could be reduced. New housing is heavily taxed and over regulated (the same cannot be said of existing stock). Something like a quarter to a third of the cost of the new home in an urban fringe location is due entirely to various taxes, charges and compliance costs (which do not apply to existing stock). It is also affected by the rapid escalation in land costs due to policy induced supply constraints in areas of ample available land (the same can't be said of existing stock in mostly built-out inner or middle ring areas). Most of these additional costs of supply owe themselves to policy changes made since the early 2000s – precisely the time when the affordability gap began to widen.

It does seem a compelling place to start.

We should aspire to a more competitive Australia but this policy effort cannot just focus on labour costs because our incomes, while high by competitor standards, are now generally insufficient to cover one of the basic necessities of life: shelter. We have made this happen because policy makers have deliberately increased the cost of delivering new housing with new taxes, charges and compliance costs, all justified on esoteric planning or sustainability principles but impossible to justify on social equity or economic grounds.

These policy changes were made to suit political agendas at the time: they were not needs-based or market-based policy changes. (It also has to be said the political agendas at the time were in the hands of Labor State governments, starting with Bob Carr in NSW but which spread rapidly to other jurisdictions. Why Labor Governments introduced policies which hurt people on working wages is as mystifying to me as to why Liberal Governments have continued to maintain the same policy positions, with minimal amendment).

The gap between the cost of supplying even relatively basic housing on the urban fringe, and the incomes of the people who in past generations could afford it, will continue to widen unless regulators and policy makers begin to grasp the wider economic consequences of policy-inflated costs for new housing supply.

Footnote: why a five times multiple? There is no strong reason. The authors of the global housing affordability report Demographia will argue that affordable housing should be around three times incomes. Moderately unaffordable they define as between 3 and 4, and between 4 and 5 is defined as 'seriously unaffordable.' The multiples of 7 or 8 times incomes, which we're seeing in Australia, are off the scale. But for the purpose of argument, if even relatively high (by international standards) multiples of 5 times incomes seems like a utopian dream, it illustrates how far incomes need to rise or costs of new supply should fall before we get even close to the situation that prevailed for most of our history. It's a big challenge.
