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...

This paper considers dynamic panel models with a factor error structure that is correlated with the regressors. Both short panels (small T) and long panels (large T) are considered. With a small T, consistent estimation requires either a suitable formulation of the reduced form or an appropriate...

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...

The paper assesses the causal relationship between formal volunteering and individual health. The econometric analysis employs data provided by the Income and Living Conditions Survey for the United Kingdom carried out by the European Union’s Statistics (UK-SILC) in 2006. Based on 2SLS,...

In this paper we examine the effect of dollar stores on children's Body Mass Index (BMI). We use a dataset compiled by the Arkansas Center for Health Improvement which created and implemented the BMI screening process for all public school children in the state of Arkansas. We combine propensity...

The paper examines the association between marital status and self-reported health status of Indian adults. A nationally representative cross-sectional data surveyed by National Sample Survey Organisation (NSSO) in 2004 is used. Results confirm linkages between marital status and health and show...

The paper examines the association between marital status and self-reported health status of Indian men and women of different ages. Estimation results reveal linkages between marital status and health and show that this relationship is sensitive to the age and gender. Based on findings, the...

The short-term effects of public smoking bans on individual smoking and drinking habits were investigated in this paper. In 2005, a smoking ban was introduced in Italy, and we exploited this exogenous variation to measure the effect on both smoking participation and intensity and the indirect...

The Two-Stage Least Squares (2-SLS) is a well known econometric technique used to estimate the parameters of a multi-equation (or simultaneous equations) econometric model when errors across the equations are not correlated and the equation(s) concerned is (are) over-identified or exactly...
