A New Approach to Personal Income Distribution
نویسندگان
چکیده
The results of R dynamical random surface model (2-dimensional quantum gravity with a R term) are applied to explain the personal income distribution. A scale invariance exists if there is not the R term in the action. The R term provides a typical scale and breaks the scale invariance explicitly in the low and middle income range. A new distribution, Weibull distribution, is deduced from the action analytically in the low income range, and a consistent fitting is obtained in the whole income range. Also, we show that the lognormal distribution in the middle income range can be understood in this framework.

متن کاملExplaining the Growth in Inequality during the Transition
To explain the change in inequality that has occurred in all transition economies, we need first to present the economic changes in terms of what happened to incomes of different social classes, and then to translate this into the “language” of personal incomes. This is, of course, a common problem of moving from social classes and thus factoral income distribution to personal income distributi...
