Prior to 2005, it seemed like house prices always rose and never fell. This has also been the case from mid-2012 through mid2018. When the demand for housing increases, prices in the housing market rise, but not always by much. For prices to rise substantially, the supply of housing must be relatively inelastic. That is, if the quantity supplied increases rapidly whenever house prices rise, price increases will remain small. Many have suggested government policies to increase the elasticity of supply. What specific policies might hold prices down when demand increases? Explain.
