The U.S. Environmental Protection Agency (USEPA) maintains networks of pollution monitors for two basic purposes: to check and enforce the attainment of national ambient air quality standards (NAAQS) and to provide useful data for studying pollution and its effects. These purposes imply...

Estimation of limited dependent variable models with dependent obse rvations has received relatively little attention due to the computational complexity of the maximum likelihood estimator. The authors develop a computationally-attractive and relatively efficient estimator for this case that...

The authors extend Daniel McFadden's (1989) method of simulated moments to approximating efficient estimators in general estimation problems. The general approach applies a simulated bias correction to an approximation of the efficient score. They discuss a general trade-off in estimator...
