Most inequality and poverty theory analyzes "equivalent income" distributions for homogeneous populations: incomes are assumed to be deflated by an equivalence scale that accounts for differences in needs between households. Yet in practice there is no consensus about what the appropriate...

The authors develop two simple measures of how much inequality is explained by individual population characteristics or groups of characteristics, analogous to R[superscript 2] in regression analysis. The authors investigate the measures' empirical implementation using several alternative...

The authors respond to J. Banks and P. Johnson's (1994) comment on Coulter et al. (1992) drawing on a more general discussion of parametric equivalence scale and scale relativity issues and new empirical results. The authors show that criticisms of their earlier work are unfounded. When the...

Using the first four waves of the British Household Panel Survey (1991-94) and a variety of methods, the authors show that there is much mobility in household net income from one year to the next in Britain. However, most income changes from one year to the next are not very large and, when...

This paper models the probability a lone mother is in employment and the probability a lone mother works full-time using the 1989 U.K. Lone Parents Survey. It complements the work by J. F. Ermisch and R. E. Wright (1991) and I. Walker (1990) based on data from the late 1970s and early 1980s....
