Parametric Equivalence Scales and Scale Relativities
回应了Banks和Johnson对Coulter等人早期工作的批评，通过参数等价尺度的讨论和新实证结果，证明批评不成立，并重申尺度相对性与不平等、贫困指数之间的关系可能因指数而异。
We respond to Banks and 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. We show that criticisms of our earlier work are unfounded. When the McClements scale is properly characterised, the scale does indeed provide lower estimates of poverty and inequality levels than most other scales. We reiterate our conclusion that relationships between scale relativities and inequality and poverty indices may be index-specific. Moreover the picture about distributional trends may differ from that about levels.
