Something New, Something Old: Parametric Models for the Size of Distribution of Income

摘要: Two new probability density functions (generalized beta and quadratic elasticity) are considered as models for the size distribution of income. The generalized nests first second kind, gamma, lognormal Pareto well introducing a number distributions to literature. elasticity provides another generalization gamma distribution. beta, have been widely used in income These many their special cases fit into five sets US family data 1970, 1975, 1980, 1985, 1990. This permits comparison relative several over time.
