Simultaneous Equations
Related Terms: Endogeneity; Endogenous Variable

A set or series of equations that interact in a way that requires estimation of all related equations to produce estimates with desirable properties (e.g., unbiaseness, consistency, and efficiency). The equations may contain some of the same variables and/or the error terms in the equations may be correlated across equations.
