A city may limit the number of cabs in many ways. The most common method is an explicit quota using a medallion that is kept forever and can be resold. One alternative is to charge a high license fee each year, which is equivalent to the city's issuing a medallion or license that lasts only a year. A third option is to charge a daily tax on taxicabs. Using figures, compare and contrast the cquilibrium under each of these approaches. Discuss who wins and who loses from each plan, considering consumers, drivers, the city, and (if relevant) medallion owners. (Hint: See the "Licensing Cabs" Application and the discussion of Figure $9.6 .$

Key Concepts

Tax Incidence and Welfare Effects

Tax incidence analysis examines who ultimately bears the burden of the taxes or fees imposed in the market. Depending on whether the cost is transmitted more to consumers through higher prices or more to drivers through reduced earnings, the welfare effects will vary. Evaluating these effects is crucial for understanding the distributional consequences of each regulatory approach across different stakeholders such as consumers, drivers, the city, and medallion owners.

Market Equilibrium Under Regulation

In regulated industries, government policies such as quotas, fees, or taxes influence the supply of services, shifting the market equilibrium. These policies affect the number of operating firms (or vehicles, in the case of cabs), thereby altering market prices and quantities. Analyzing equilibrium under these regulations helps determine how consumer surplus and producer (or driver) surplus are redistributed as a result of changes in supply constraints or cost structures.

Economic Rent and Scarcity

When supply is explicitly limited (for instance, through medallions), a scarce good is created, leading to the generation of economic rent. Medallions capture value above and beyond the merely competitive operating profit because the number of medallions is artificially limited. The resale value of such licenses reflects this scarcity and represents a transfer from potential entrants or consumers to medallion holders.

License Quotas/Medallion Systems

A medallion system represents an explicit quota on the number of service providers. This type of regulation restricts entry into the market and can generate long-term rents for medallion holders due to the fixed number of licenses. It often leads to higher fares or reduced service efficiency, while creating a market for buying and selling these medallions, effectively transferring income to medallion owners.

Annual Licensing Fee Strategy

Charging a high annual fee for licensing is an alternative approach where the right to operate is granted on a temporary basis, but at a high cost each year. This method equates to an annual rent but ensures a periodic renewal that could adjust to economic conditions. It affects the market equilibrium by incorporating a fixed cost into each operator's decision, potentially lowering net supply compared to an unregulated environment while avoiding the long-term transfer of economic rents to holders.

Daily Taxation on Service Providers

Imposing a daily tax operates as a variable cost charged for each unit of service provision, akin to a per-ride or per-day cost. This approach does not restrict the number of participants but increases the operational cost for each service provider, thereby indirectly reducing the equilibrium level of output. Its impact on the market depends on the elasticity of supply and demand, determining how the tax burden is shared between consumers and providers on a daily basis.
