WebThe restriction across equations (1) and (2) is exemplary of the type of restrictions that typically occur in linear rational expectations models. The matrix A that governs the dynamics of the {z t} process also shows up in the formula for the wealth-consumption ratio, and this is the cross equation restriction. WebcrossEquConst Only used if the number of regressors are the same in each equation. It is a vector which indicates which coefficient are constant across equations. The order is 1 for Intercept and 2 to k as it is formulated in the formulas g. Setting it to 1:k is equivalent to setting commonCoef to TRUE. Details
