A macro model incorporating rational expectations in financial markets (the Murphy Model - MM) is used to endogenize the macroeconomic environment
for a comprehensive general equilibrium model (ORANI). The interface exploits the existence of variables which are endogenous to both models,
calibrating on a shock to government spending, which is the principal common exogeneity. The responses of the half-dozen doubly endogenous
variables feature prominently in the calibration procedure, which minimizes any conflict between the stories told about these variables by the two
models. Prospective benefits include:
(1) to the numerous policy-oriented users of ORANI, a facility allowing the macroeconomic environment to be determined by a macrodynamic model
such as MM;
(2) to these users, reassurance that ORANI's short-run translates in calendar time to about two years;
(3) to the clientele of a macro model, the possibility of much more detailed projections..
