Taxi service with heterogeneous drivers and a competitive medallion market

This paper incorporates two novelties into steady-state, macroscopic models of street-hail taxi service: (i) het-erogeneous drivers; (ii) explicit treatment of a competitive rental market for medallions (the rights to cruise for passengers). When drivers vary only by reservation wage, issuing medallions raises every driver's take-home pay, and the social optimum requires subsidy. When drivers vary only by marginal cost, issuing medallions may hurt drivers with low-enough marginal costs. Also, when quality declines with marginal cost, the social optimum may require a binding medallion quota or tax.
