摘要
林达尔局部均衡模型中得出的公共产品价格是一种"市场出清"价格,其定价原则是个人支付意愿总和等于边际成本。由于现实生活中存在"搭便车"者的机会主义行为、隐瞒个人偏好以及需求的不确定性,林达尔局部均衡模型是不完美的。文中考虑了现实中更具普遍意义的准公共产品,并引入需求的随机变量,以社会福利最大化为目标函数研究了准公共产品的定价问题,得出了不同配给条件下准公共产品不同的有效价格。
The public goods＇ price attained by Lindahl＇s partial equilibrium model is a ＇market-clearing＇ price, and the pricing principle is that the sum of private＇s payoff willing equals the marginal costs. But the model is imperfect because of the existing of opportunistic behavior of the ＂free-rider＂, hiding of one＇s own preference and uncertain demands. This paper considers the quasi-public goods because of its universalism and introduces a stochastic variance of demand. In the end, the pricing of quasi-public goods is studied based on welfare-maximizing function and the different optimal prices of quasi-public goods are achieved under corresponding rationing conditions.
