Housing

The Greens released their much-hyped housing plan last week and while I wouldn’t normally give this much attention to a minor party’s policy, it was just so full of well-meaning but really confused policy, I just had to weigh in.

Dick Smith wants to cap Australia’s population at 30 million over concerns about a lack of resources and housing costs. In doing so he falls for the ’lump of labour’ fallacy, and fails Econ 101: it’s poor planning, not immigrants, that erodes housing affordability in Australia.

NSW, WA and SA have all announced steps that will increase housing supply. But to improve housing affordability for good, we need to ensure it’s politically sustainable. That means communicating with locals and lifting density across entire cities, not just in ‘well-located’ areas.

Whether immigrants fuel inflation is a complicated question, in part because there’s no single, uniform “immigrant”. Immigrants can be students, skilled workers, entire families, refugees, retirees, or backpackers. Their ages also vary, as do their consumption, savings, and working patterns.

When you create a system that makes it costly to do things ‘by the book’ – common examples are drugs, guns and more recently, building houses – you alter the incentives that individuals face in their day-to-day lives. In the case of housing, strict planning and zoning laws create positive transaction costs, raise the price of houses, and increase the payoffs for criminality.
