### Overview
- Paper examines how two types of fiscal policy models—dynamic macroeconomic models and applied general equilibrium models—have integrated macro- and microeconomic relationships within a framework of intertemporal equilibrium.
- Emphasizes potential advantages of integrating macro- and microeconomic relations.
- Discusses limitations of intertemporal equilibrium models, particularly weaknesses of saving and investment theories incorporated in the models.
- Concludes that, despite recent important advances, policymakers need to exercise caution when they interpret results derived from these models.

### Key findings and substantive points
- Integration of macro- and microeconomic relations can offer potential advantages for fiscal policy modeling.
- Intertemporal equilibrium models used in the literature exhibit important limitations.
- Weaknesses identified are concentrated in the saving and investment theories incorporated in intertemporal equilibrium models.
- Despite recent important advances in modeling, interpretation of model results requires caution by policymakers.
