Endogenous Population with Public Goods and Malthusian Fixed Resources: Efficiency or Market Failure
构建了一个理论人口模型，同时考虑国家追求人口规模的政治经济动机和马尔萨斯压力，发现这两种外部性并不会导致市场失灵或损害社会的生育决策。
A theoretical population model is developed which takes into account both the desire of a nation for a large population for political and economic reasons as well as the Malthusian pressures that suggest that there is a natural tendency toward overpopulation. The model assumes that parents care about both the number and well-being of their children. The results show that these two possible sources of externality do not lead to market failure nor to unfettered competitive individual decisions concerning childbearing that are detrimental to society.
