Housing Policy

Area: Policy and financing

Housing policies are usually understood in a narrow manner as social policies targeting ' expensive' housing prices through housing allowances, tax deduction or social housing allocation. However, this definition takes a different approach and draws from a larger body of economic literature to identify the wider array of policies that impact housing markets. Broadly speaking, housing markets are influenced through fiscal, macroeconomic, prudential and structural policies (Hilbers et al., 2008). These public policies have clear impacts on housing demand and supply and also often create synergies between each other. Fiscal policies have a stronger impact on income and costs through taxation and subsidies. One of the main fiscal policies with regard to housing is the mortgage interest deduction which reduces user costs for the homeowner and can produce increases in property prices (Poterba, 1984). Macroeconomic policy regulates the money supply through interest rates. Housing has usually been perceived as a conveyor belt for macroeconomic policy as the expansion of the money supply through low interest rates or quantitative easing has the potential to increase demand during recessions counteracting the procyclical behaviour of financial markets (Muellbauer, 1992). Prudential policies determine the level of risk associated with lending through Loan-to-Value (LTV) and Debt-to-Income (DTI) ratios. The Global Financial Crisis (GFC) that started in the US in 2008 is usually seen as the failure of prudential policy that resulted in the tightening of loans (Whitehead & Williams, 2017) and  drew renewed attention to housing policy from central banks, policymakers, and economists (Piazzesi et al., 2016). Structural policies regulate housing supply, this includes planning regulations and environmental standards. For example, research from the US has shown that zoning laws can have a relevant impact on housing affordability by constraining supply (Glaeser & Gyourko, 2002). While most research is conducted selectively on each of these policy interventions, there are relevant synergies between policy domains that can be identified. These policies usually work in conjunction with each other: lax prudential policies and favourable home ownership taxation together with low interest rates and tight planning controls can lead to higher property prices. Conversely, constrained lending, brick-and-mortar subsidies and higher interest rates are known to mitigate rising house prices.

* This vocabulary consists of definitions of key terms related to the combined research conducted by the 15 early-stage researchers. Each term has multiple definitions, each connected to one of the three main research areas: Design, Construction and Planning; Community Involvement; and Policy and Funding.

The joint construction of this vocabulary allows the researchers' projects to be interwoven. As such, the vocabulary is a tool for conducting transdisciplinary research on affordable and sustainable housing.

Entries are reviewed by RE-DWELL researchers and supervisors. The vocabulary is updated regularly.
