1. frontier: Stochastic Frontier Analysis - Maximum Likelihood Estimation of Stochastic Frontier Production and Cost Functions. Two specifications are available: the error components model (Battese and Coelli, 1992) and the efficiency effects model (Battese and Coelli, 1995).
4. systemfit: Estimating Equation Systems - The systemfit package contains functions for fitting systems of linear and nonlinear simultaneous equations using Ordinary Least Squares (OLS), Seemingly Unrelated Regressions (SUR), Two-Stage Least Squares (2SLS), and Three-Stage Least Squares (3SLS).

7. econMisc: Misc. Econometrics Functions - Various econometric-related functions. This package is intended to become a 'parking lot' for econometrics-related functions on their way to better-suited packages. It can be used as any standard R package.
8. Generalized method of moments - This package offers a complete set of tools to estimate models based on moment conditions. It includes the generalized method of moments (GMM) and the generalized empirical likelihood (GEL).
