Simultaneous equations with random coefficients: Estimating the structural form

  • Silvia Terzi


For a system ofG simultaneous equations and a time series of cross sectional data we estimate the structural form under the assumption that the regression coefficients are random variables. In particular, given the model:
$${}_iYT + {}_iX{}_i\Delta + {}_iE = 0 i = 1,...,n$$
to account for differences in behaviour over the cross sectional units we assume that the coefficient matrices of the exogenous variables for each unit, that is{ i Δ|, form a sequence of independent random variables with common mean\(\bar \Delta \) to be estimated. We derive feasible two stage generalized least squares estimators of the parameters Γ and\(\bar \Delta \).
