5.4. Solution for (φ, a, μ, к) in the Fixed-Employment Economy

The general stable solution to the differential equation system (A9) is represented by the
following expressions:

φ = φ + Eleψ1t + E2eψ2t                        (A10a)

a = a ■ Fleψ1t + F2eψ2t                           (A10b)

μ = μ + Gleψ1t + G2eψ2t                        (A10c)

к = fc + Lleψ1t + L2eψ2t

(A10d)


where Ei, Fi, Gi and Li, i = 1, 2 are constants (eigenvectors) corresponding to the stable
eigenvalues
ψl and ψ2 of the fixed employment economy (I = I) and where φφ, a, μ, /ŋ are
the steady-state solutions derived from the system (A7a)-(A7c). Since only two of these
constants are independent, the
first step in obtaining the complete solution is to solve
E
i, Fi, Gi in terms of Li, i = 1, 2. These relationships, using (A8) and (AlOa)-(AlOd), are
calculated from the homogeneous system:
