Explore the economic context of urban land markets, analyzing multiple consumers and location attributes, and modeling consumers' behavior to measure benefits of land use changes through regulations and transport projects. Learn about auction market equilibrium analysis and calculating consumers' surplus and total benefits.

Measuring Land Use Benefits in Auction Markets Francisco Martínez University of Chile European Transport Conference Cambrigde 2001
Economic context The urban land market • Multiple consumers: residents and firms • Multiple location attributes • Location externalities • A variety of zone-building options • Auction market: imperfect competition • Market equilibrium analysis Measures of benefits of land use changes • Regulations • Transport projects
Modelling Consumers’ behaviour Indirect & conditional utility p: exogenous price for z yieldingU Max value for z to achieve U Compensated demand Expenditure funtion
Auction markets:linear marginal utility of income Location prices are endogenous: highest bid Def. auction equilibrium : Theorem 1: Thus for More...
Proof: From Roy’s theorem and demand =1: In E: Variation in U: Variation in z:
Interpretation Theorem 1: Since: • in the auction market prices are always the WP for the final consumer • for two identical consumers in (I,), these endogenous prices are different at different sites, but utility is the same Then, such prices HAVE to comply with theorem 1; other prices do not.
Consumers’ WP function Theorem 2: within E, WP is doubly linear, in I and U Follows from comsumption of one unit and Roy’s Theorem under Theorem 1 then
Measuring consumers’ surplus The classical measures: for (p,z,U) at equilibrium Notice U1 p=WP
Measuring total benefits For a given location: Total Benefit = Consumers’ + Producers’ surplus Change in WP caused by changes in built environment Obs.: 1) extenal conditions 2) location externalities, agents interacction
Summary Urban market characteristics: One location.......WP linear in I + Auction market....WP linear in U • WP is doubly linear • Income variation EV=CV=CS • Total benefits measurable from WP values
Some implications Total benefits are • change in WP valued at constant U, or • change in U plus change in rents, or • change in consumers value of built environment. They are NOT equal to change in rents
