论文摘要
我们研究质量维度如何影响两个设施提供公共服务的空间差异模型中的社会最佳。如果质量在个人的效用功能中线性进入，则一种对称配置，在这种配置中，这两个设施具有相同的质量，并且服务于相同规模的个人组，并且不会使社会福利最大化。这是一个令人惊讶的结果，因为所有个人都具有相同的质量估值。我们还表明，如果个人的边际质量降低，设施的对称配置可能会最大化社会福利。
We study how the quality dimension affects the social optimum in a model of spatial differentiation where two facilities provide a public service. If quality enters linearly in the individuals' utility function, a symmetric configuration, in which both facilities have the same quality and serve groups of individuals of the same size, does not maximize the social welfare. This is a surprising result as all individuals are symmetrically identical having the same quality valuation. We also show that a symmetric configuration of facilities may maximize the social welfare if the individuals' marginal utility of quality is decreasing.
