Methods

One of the areas of policy research where randomized field trials have been utilized most intensively is welfare reform.

We present a short review of Friedman's Permanent Income Hypothesis, the origins of the idea and its theoretical foundations.

Recent theoretical work has shown the importance of measuring microeconomic uncertainty for models of both general and partial equilibrium under imperfect insurance.

In this paper we consider conditions under which the estimation of a log-linearized Euler equation for consumption yields consistent estimates of the preference parameters.

In an effort to improve the small sample properties of generalized method of moments (GMM) estimators, a number of alternative estimators have been suggested.

This paper considers the identification and estimation of hedonic models.

This paper provides weak conditions under which there is nonparametric interval identification of local features of a structural function which depends on a discrete endogenous variable and is nonseparable in a latent variate.

In this paper I summarize some recent developments in the literature on the econometrics of program evaluation.

We survey microeconometric research on investment and emplyment that has used panel data on individual firms or plants.

This papers studies and compares the asymptotic bias of GMM and generalized empirical likelihood (GEL) estimators in the presence of estimated nuisance parameters.

We consider the estimation of parametric models for stationary spatial orspatio-temporal data on a d-dimensional lattice, for d ≥ 2.

Parents with higher education levels have children with higher education levels.

This paper concerns the identification and estimation of a shape-invariant Engel curve system with endogenous total expenditure.

Fixed effects estimators of panel models can be severely biased because of the well-known incidental parameters problem.

For vectors x and w, let r(x;w) be a function that can be nonparametrically estimated consistently and asymptotically normally.

There is renewed interest in why people of lower socio-economic status (SES) have worse health outcomes.

Conditions are derived under which there is local nonparametric identification of values of structural functions and of their derivatives in potentially nonlinear nonseparable models.

We provide easy to verify suffcient conditions for the consistency and asymptotic normality of a class of semiparametric optimization estimators where the criterion function does not obey standard smoothness conditions and simultaneously depends on some preliminary nonparametric estimators.
