It is shown that in a nonparametric nonseparable triangular system, the conditional moment restriction (CMR) does not identify the average structural function (ASF). The CMR identifies the ASF only if the model is structurally separable in observable covariates and unobservable random errors....

This paper investigates potential measurement error biases in estimated poverty transition matrices. We compare transition matrices based on survey expenditure data to transition matrices based on measurement-error-free simulated expenditure. The simulation model uses estimates that correct for...

We study the asymptotic distribution of three-step estimators of a finite dimensional parameter vector where the second step consists of one or more nonparametric regressions on a regressor that is estimated in the first step. The first step estimator is either parametric or non-parametric....

The benefits of panel data are well-documented but missing data problems are often more severe. In particular, units that respond in the first wave may drop out of the panel after one or more periods of participation. This paper focuses on identification and Maximum Likelihood estimation of...

The authors investigate whether an equilibrium search model, in which the wage offer distribution is endogenous, is able to describe observed labor market histories. They find that the distributions of job and unemployment spells are consistent with the data, and qualitative predictions of the...

We analyze the impact of unemployment benefits and minimum wagesusing an equilibrium search model which allows for dispersion ofbenefits and productivity levels, job-to-job transitions, andstructural and frictional unemployment. The estimation method usesreadily available aggregate data on...

On the basis of the baseline data collected for the evaluation of the Bolivian Social Investment Fund (SIF) this paper assesses (1) the benefit incidence of the SIF and (2) the quality of the evaluation design. We find that the benefits in education are most equally distributed over the...
