Simultaneous Solution of Control System Equations in EMTP

IEEE Transactions on Power Systems, 2006
The existing approach for solving control systems in the Electromagnetics Transients Program is to insert one-time-step delays for breaking feedback loops when one or more nonlinear functions is encountered. Although this approach may remain acceptable for several well-behaved cases, it provides a nonsimultaneous solution for a nonlinear system.

Control functions in nonseparable simultaneous equations models [PDF]

open access: yesQuantitative Economics, 2014
The control function approach (Heckman and Robb (1985)) in a system of linear simultaneous equations provides a convenient procedure to estimate one of the functions in the system using reduced form residuals from the other functions as additional ...

Disequilibrium Econometrics in Simultaneous Equations Systems

Econometrica, 1980
This paper considers the econometric problems raised by multi-market disequilibrium models. It uses a specification which is derived from general disequilibrium theory and, therefore, provides a first bridge between the economic theory approach and the econometric theory approach of disequilibrium.

Heteroskedasticity in simultaneous equation systems

Economics Letters, 1991
Abstract Little has been written on heteroskedasticity in simultaneous equation systems. This paper proposed a two-stage instrumental variable estimator that is more efficient than both the standard 2SLS estimator, with and without weights, and an estimator proposed by White.

A Family of Estimators for Simultaneous Equation Systems

International Economic Review, 1974
THE PURPOSE OF THIS PAPER is to set forthl, in a systematic fashion, a family of estimators for systems of simultaneous stochastic equations based on modifications and simplications of the method of maximum likehood. It is hoped that this family will satisfy the need in most practical applications involving linear as well as non-linear structural ...

Comparing Single-Equation Estimators in a Simultaneous Equation System

Econometric Theory, 1986
Comparisons of estimators are made on the basis of their mean squared errors and their concentrations of probability computed by means of asymptotic expansions of their distributions when the disturbance variance tends to zero and alternatively when the sample size increases indefinitely.

Method‐of‐moment view of linear simultaneous equation systems [PDF]

open access: possibleStatistica Neerlandica, 2008
In this paper, we review the modern method‐of‐moment‐based approaches to identification and estimation of linear simultaneous equation systems. First, we present the rank condition for the structural form (SF) parameter identification. The rank condition comes naturally and is much easier to understand than that in the conventional reduced‐form‐based ...

The Bias of Instrumental Variable Estimators of Simultaneous Equation Systems

International Economic Review, 1977
This paper examines the discussion in the econometric literature of the conditioins which instruments should satisfy in order to be used in the single equation Iiistrumental Variable (IV) estimation of structural parameters in a simultaneouIs equation system. The Two Stage Least Squares (TSLS) estimator can be interpreted as an IV estimator.
