I reconsider various methods for correcting for bias in estimates of the returns to schooling. I argue that the literature on ability bias has ignored complications implicit in theoretical formulations of the choice of human capital. In particular, such models imply that adding ability to the...

Coming from standard economic growth theory and empirical evidences, we concentrated on the convergence process as a result of structural changes in economy. We investigate the differences among countries in EU in terms of the share in total economy of main sectors. Then, based on the spatial...

This paper considers the issue of GMM estimation of a short dynamic panel data model when the errors are correlated across individuals. We focus particularly on the conditions required in the cross-sectional dimension of the error process for the dynamic panel GMM estimator to remain consistent....

This paper explores the validity of the two-stage estimation procedure for sparse linear models in high-dimensional settings with possibly many endogenous regressors. In particular, the number of endogenous regressors in the main equation and the instruments in the first-stage equations can grow...

The paper analyses if monetary rewards to continuative Italian volunteers decrease their intrinsic motivation undermining the satisfaction of psychological needs for autonomy and competence. It uses a Survey on Employment in the Social Care and Educational Services conducted by FIVOL-FEO in...

This study employed a stochastic frontier translog cost and production functions to measure the level of allocative efficiency and it’s determinants in small-holder cocoyam production in Anambra state, Nigeria. A multi-stage random sampling technique was used to select 120 cocoyam farmers in...

This work considers the relative performance of municipal schools (MUN) and individuals subsidized (PS) with different strategies from identification, ordinates from most basic - supposing the absence of selection slant and characteristics multilevels in the observations until which it relaxes...

The purpose of this study is to evaluate the determinants of technical efficiency of wheat small farmers in Bío Bío Region, especially to investigate the relation between social capital, measured through participation in organizations, and technical efficiency. Using information of the VII...

We provide Monte Carlo evidence on the finite sample behavior of the conditional empirical likelihood (CEL) estimator of Kitamura, Tripathi, and Ahn (2004) and the conditional Euclidean empirical likelihood (CEEL) estimator of Antoine, Bonnal, and Renault (2007) in the context of a...

In this paper, I present an empirical model of learning under ambiguity in the context of clinical trials. Patients are concern with learning the treatment effect of the experimental drug, but face the ambiguity of random group assignment. A two dimensional Bayesian model of learning is proposed...
