Porterba 1992<br />

Calculates compensated elasticity using estimates in literature and<br />

Slutsky eqn.<br />

Rosen (1982):<br />

Income elasticity: 0.75<br />

Housing share: 0.25<br />

ε H,r = −1<br />

⇒ Compensated elasticity: −1 + 3 4 × 1 4 ≃ −0.8<br />

Intuition for large elasticity: broker calculates “how much house you<br />

can afford” if they spend 30% of income<br />

Can “afford” more with larger tax subsidy → tax is effectively salient<br />

Calculates amount of overconsumption of housing and effi ciency cost<br />

of housing subsidy<br />
