Regression and linear programming provide the basis for popular techniques for estimating technical efficiency. Regression-based approaches are typically parametric and can be both deterministic or stochastic where the later allows for measurement error. In contrast, linear programming models are nonparametric and allow multiple inputs and outputs. The purported disadvantage of the regression-b...

We consider panel count data which are frequently obtained in prospective studies involving recurrent events that are only detected and recorded at periodic assessment times. The data take the form of counts of the cumulative number of events detected at each inspection time, along with explanatory covariates. Examples arise in diverse areas such as epidemiological studies, medical follow-up st...
This paper studies estimation and inference in a quantile regression dynamic panel model with fixed effects. Panel data fixed effects estimators are typically biased in the presence of lagged dependent variables as regressors. To reduce the dynamic bias in the quantile regression panel data model I develop an instrumental variables approach that employs lagged regressors as instruments. I show ...
This paper studies fixed effects estimation of quantile regression (QR) models with panel data. Previous studies show that there are two important difficulties with the standard QR estimation. First, the estimator can be biased because of the well-known incidental parameters problem. Secondly, the non-smoothness of the objective function significantly complicates the asymptotic analysis of the ...
Rising costs of public employee pension plans are a source of fiscal stress in many cities and states and have led to calls for reform. To assess the economic consequences of plan changes it is important to have reliable statistical models of employee retirement behavior. The authors estimate a structural model of teacher retirement using administrative panel data. A Stock-Wise option value mod...
so far the static properties of hadrons have been introduced in various models. the static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. in this work we have introduced the hypercentral constituent quark and isospin dependent potentials. here constituent quarks interact with each other via a potential in which we have ta...
