The Size Distribution of Personal Inco
نویسنده
چکیده
This paper examines the hypothesis that short run changes in tne U.S. size distribution of personal income have been systematically related to aggregate levels of output~ personal income~ and employment during the posh7ar period. Part one proposes a procedure for describing the size distribution of income. The observed distribution is approximated by a displaced lognormal distribution vmich corresponds formally to the three parameter lognormal distribution. Quantile methods of curve fitting are used. Part b~o examines postwar movements in measures of the size distribution. Separate patterns are established for each of three family groups~ families with a male head and a wife in the labor force~ those with a male head and a ~vife not in the labor force~ and those with a female head. In-part three these patterns are related to changes in aggregate personal income components and in aggregate leveles of employment and labor force participation. For each group a three equation system is used to estimate mean income and aqo relative quantile measures. Distributionar~responsesof the three groups are compared. Some tentative conclusions are dravm in part four.

A Quasi-Polynomial-Time Algorithm for Sampling Words from a Context-Free Language
A quasi-polynomial-time algorithm is presented for sampling almost uniformly at random from the n-slice of the language L(G) generated by an arbitrary context-free grammar G. (The n-slice of a language L over an alphabet is the subset L\ n of words of length exactly n.) The time complexity of the algorithm is " ?2 (n jGj) O(log n) , where the parameter " bounds the variation of the output distr...

The ECMWF 10 meter wind field and spectral wave boundary condition at 18 ْN degree are input into one of the latest versions of numerical wave models (3rd generation) after a few local modifications. ...
متن کاملDepth Reduction for Circuits of Unbounded Fan-In
We prove that constant depth circuits of size n log O(1) n over the basis AND, OR, PARITY are no more powerful than circuits of this size with depth four. Similar techniques are used to obtain several other depth reduction theorems; in particular, we show every set in AC 0 can be recognized by a family of depththree threshold circuits of size n log O(1) n . The size bound n log O(1) n is optima...
