An Engel Curve Analysis of Gambling and Insurance in Brazil
研究了巴西通过人寿保险和彩票融资经济发展的两种方式，估计了恩格尔函数和收入弹性，发现不同城市的人寿保险购买模式存在差异，且所有收入水平的彩票支出通常超过保险支出。
This paper focuses upon two methods of financing economic development in Brazil: private capital formation through life insurance and public capital formation through government lottery programs. Engel functions are determined for these services as well as their associated income elasticities. Disparate patterns of life insurance purchases are shown to exist between cities, and lottery expenditures generally exceed insurance expenditures at all income levels. These statistical estimations provide initial steps in determining and planning the alteration of the incidence of the capital formation burden over various income groups.
