The Measurement of Educational Inequality: Achievement and Opportunity This paper proposes two related measures of educational inequality: one for educational achievement and another for educational opportunity. The former is the simple variance (or standard deviation) of test scores. Its selection is informed by consideration of two measurement issues that(More)
The measurement of inequality of opportunity has hitherto not been attempted in a number of countries because of data limitations. This paper proposes two alternative approaches to circumventing the missing data problems in countries where a demographic and health survey (DHS) and an ancillary household expenditure survey are available. One method relies(More)
Diggle's tests of spatial randomness based on empirical distributions of interpoint distances can be performed with and without edge-effect correction. We present here numerical results illustrating that tests without the edge-effect correction proposed by Diggle (1979, Biometrics 35, 87-101) have a higher power for small sample sizes than those with(More)
We examine the long-term effects on individual economic outcomes of a set of earthquakes – numerous, large, but mostly not extreme – that occurred in rural Indonesia since 1985. Using longitudinal individual-level data from large-scale household surveys, together with precise measures of local ground tremors obtained from a US Geological Survey database, we(More)
Through interpretations of remote-sensing data and/or theoretical propositions, the idea that forest and savanna represent “alternative stable states” is gaining increasing acceptance. Filling an observational gap, we present detailed stratified floristic and structural analyses for forest and savanna stands located mostly within zones of transition (where(More)
We study the effects of admission into elite public high schools in Mexico City on students' expected earnings, arguing these effects provide an indication of the value-added those schools produce. Using data for the centralized and exam-based allocation of students into schools and an adapted regression discontinuity design strategy, we find that admission(More)
This paper proposes two simple scalar measures of inequality of opportunity: inequality measured in the “smoothed distribution” corresponding to a given partition of the population into circumstancehomogeneous types (IOL), and the ratio of that quantity to overall inequality in the original distribution (IOR). Both measures are derived from a weak(More)
Investment in land administration projects is often considered key for agricultural productivity and rural development. The evidence on such interventions is however remarkably mixed. This paper discusses a number of challenges and derives related guidelines for the impact evaluation of land administration programs. We focus on four types of challenges: 1)(More)
It is often claimed that standard measures overestimate the extent of inequality and poverty on the grounds that poorer people tend to work less. The paper points to a number of reasons to question this claim. To illustrate, the labor supplies of single American adults are shown to have a positive income gradient, but with considerable heterogeneity,(More)
The standardization of test scores, which is a regular feature of most data on educational achievement, prevents a cardinal interpretation of inequality measures defined over those variables. Many common measures are not even ordinally equivalent to the original inequality in the underlying data. This paper presents comparable, ordinally equivalent measures(More)
