The Dynamics of Housing Booms and Busts: Political Influence, Interest Rates, and Economic Consequences

Patrick Boyle

Summary:
  • New Zealand's recent housing market downturn serves as a case study, demonstrating how an economy built on ever-rising house prices faces significant challenges when prices fall, leading to negative equity and construction firm insolvencies.
  • Politicians often incentivize rising house prices through subsidies, tax breaks, and restrictive building policies, to satisfy homeowner voters, despite these measures making homes less affordable in the long run.
  • Land appreciation, rather than improvements to the physical structure, drives property value increases, a non-productive form of wealth generation, as argued by Henry George with his concept of a land value tax.
  • Falling interest rates significantly increase borrowing power, inflating house prices over decades, but rising rates lead to decreased affordability and market freezes, especially in countries with variable-rate mortgages.
  • An inefficient housing market can lead to a "brain drain" of young professionals leaving for more affordable regions and can undermine national productivity by making commercial centers prohibitively expensive for skilled labor.
  • Economist Edward Leamer's theory, "Housing is the Business Cycle," highlights how housing market activity heavily influences overall economic cycles, with major recessions often preceded by drops in housing activity and transaction volumes.
  • Policy choices during a bust involve either a prolonged, painful deflation (like Japan) or a swift, chaotic correction (like the US and Ireland in 2008) that clears market imbalances and redirects capital.
