• Public Provision of Indivisible Private Goods in Short Supply
  作者：Dan Usher

  DOI：10.1177/109114210203000505

  日期：2002.9

  Public provision of private goods is usually modeled as the displacement of a market where people can buy as much or as little of a good as they please, with tax-financed provision by the government of equal and identical amounts of the good per person. But public provision is not always equal per person because some goods cannot be supplied equally or because the government does not choose to supply goods equally. There may be fewer organs available for transplant than there are people who need them. The best education and medical care are unavoidably rationed because teachers and doctors differ in skill or dedication. Total public expenditure may be insufficient to provide for everybody when there is a lower limit to useful expenditure per person.

  公共提供私人物品通常被建模为市场的替代，人们可以自由购买多少或少量的商品，而政府则通过税收提供相同数量和相同质量的商品。但是公共提供并不总是每个人平等，因为有些商品无法平等供应，或者政府选择不平等供应。例如，需要器官移植的人可能比可用器官数量更多。最好的教育和医疗保健不可避免地会被限制，因为教师和医生的技能或献身精神不同。当每个人的有用支出下限较低时，总公共支出可能不足以为每个人提供服务。
