A Dynamic Computable General Equilibrium (CGE) Model of the New Zealand Economy - WP 02/07

Appendix 2 Equations for the steady state model

The model equations are reported using TROLL syntax. Each equation begins with a label, which indicates the endogenous variable in the system. All the variables with a suffix _eq are steady state values and all the nominal variables are deflated by PYD.
