When there exists congestion externality, the equilibrium city boundary will be broader than is socially optimal. A regulator can implement growth boundary controls or impact fees to correct this inefficiency. The existing literature typically investigates the design of optimal growth boundary controls and impact fees in a framework where no uncertainty arises and where the city is an open system. This project will extend the standard literature. In the first year, this project will add uncertainty into the Brueckner’s open city model (1990). The conclusion will significantly differ from Brueckner’s as this project will assume that a regulator implements the growth boundary control that is expected by developers rather than unexpected. In the second year, this project will add uncertainty into the closed city model of Helsley and Strange (1995). This project, however, significantly differs from theirs because they investigate only the Cournot-Nash equilibrium between two cities that are subject to growth boundary controls rather than investigate the optimal growth boundary controls.擁擠外部性房屋租金不確定性及最適邊界管制與最適開發衝擊費The Design of Optimal Growth Boundary Controls and Impact Fees With Congestion Externality and Stochastic Rents on Housing擁擠外部性、房屋租金不確定性、及最適邊界管制與最適開發衝擊費
