題名 差異化地方公共財模型中之區域間租稅競爭 其他題名 Interjurisdictional Tax Competition in a Differentiated Local Public Goods Model 作者 徐麗振 貢獻者 財政系 關鍵詞 產品差異化;區域間競爭;Bertrand矛盾;Nash均衡

This paper examines a model of tax competition in which local public goods are horizontally differentiated. The model is similar to d`Aspremont, Gabszewicz, and Thisse (1979) in the sense that individuals incur a quadratic transportation cost if their most preferred types of local public goods do not coincide with the actual type provided. In a subgame framework, jurisdictions choose the type of local public goods in the first stage, then choose tax rates on labor in the second stage. After observing the tax rates and types of local public goods, individuals choose with their feet the jurisdiction that best satisfies their preferences. Two objective functions are discussed: the median voter`s utility and the total utility within the jurisdiction. I find that the quantities of local public goods reach the first-best level under both objective functions. This is also the result found in models of homogeneous public goods and individuals. Therefore, introducing the heterogeneity of local public goods does not distort the selection of the efficient labor tax rates. At the Nash equilibrium jurisdictions differentiate themselves from each other, but the equilibrium types are inefficient, however. Median voters and the benevolent local governments both have incentives to sacrifice the preference on types in exchange for a more favorable size of population, and thereby more favorable quantities of local public goods and income.<關聯 行政院國家科學委員會
