Abstract: | This paper considers intermediate and final public goods as stocks from which consumers obtain a flow of services by expending scarce time. The services so obtained depend on the time other individuals spend utilizing these same goods. Optimality conditions are derived for both stock levels and flow usage where tolls are required to cover costs. The elasticities in the resulting formulae are endogenous in the sense that only certain values are permissible. In the intermediate good case, at the optimum, the public good will always be locally optimally supplied and locally underutilized to a degree which depends on the congestion parameter. |
