We introduce a class of instrumental quantile regression methods for heterogeneous treatment effect models and simultaneous equations models with nonadditive errors and offer computable methods for estimation and inference. These methods can be used to evaluate the impact of endogenous variables or treatments on the entire distribution of outcomes. We describe an estimator of the instrumental v...
Inference on the Instrumental Quantile Regression Process for Structural and Treatment Effect Models
We introduce a class of instrumental quantile regression methods for heterogeneous treatment effect models and simultaneous equations models with nonadditive errors and offer computable methods for estimation and inference. These methods can be used to evaluate the impact of endogenous variables or treatments on the entire distribution of outcomes. We describe an estimator of the instrumental v...
This paper uses a new non-parametric, unconditional, hyperbolic order-α quantile estimator to construct a hyperbolic version of the Malmquist index. Unlike traditional non-parametric efficiency estimators, the new estimator is both robust to data outliers and has a root-n convergence rate. We use this estimator to examine changes in the efficiency and productivity of U.S. banks between 1985 and...
BACKGROUND Toxoplasmosis in immunocompetent people is generally asymptomatic but in immunocompromised patients including HIV/AIDS, cancer patients, and organ transplant recipients, etc. it can lead to serious pathological problems. The objective of current study was to determine the seroprevalence of T. gondii IgG and IgM antibodies in HIV/AIDS patients using ELISA technique in Mazandaran Provi...
OBJECTIVES Low Birth Weight (LBW) has an important role in the mortality and morbidity of neonates and the incidence of LBW may vary across different environments. The aim of this study was to determine the incidence and some related factors of LBW in Mazandaran province, Northern Iran. METHODS In this longitudinal study, all live births that were born in 5 maternity hospitals in Mazandaran p...

inflation forecasting has been one of the requirements for the implementation of monetary policy in countries which their monetary authorities are pursuing inflation targeting regime. however, owing to central bank independence in one hand and as well as the lagged effects of monetary policies on inflation in the other, the monetary authorities should have the sound perspective about the future...
Two new species records of Oplitidae, Oplitis exopodi Hunter & Farrier, 1975 and Oplitis sarcinulus Hunter & Farrier, 1976 are redescribed based on Iranian specimens from leaf-litter forest in Mazandaran province, northern Iran. A key to the Iranian species of Oplitis is presented.
