Hausman 1981: Exact Consumer Surplus<br />

Harberger formulas: empirically implementable, but approximations<br />

(linearity, ignore cross-effects)<br />

Alternative approach: full structural estimation of demand model<br />

Start from observed market demand functions, finding the best fit<br />

Estimate regression of the form:<br />

c(q, Z ) = γ + αq + δZ<br />

Then integrate to recover underlying indirect utility function v(q, Z )<br />

Inverting yields expenditure function e(q, u); now compute “exact”<br />

EB<br />

Parametric approach: Hausman (AER 1981); non-parametric<br />

approach: Hausman and Newey (ECMA 1995)<br />
