TAX POLICY AND CONSUMER FORESIGHT: A GENERAL EQUILIBRIUM SIMULATION STUDY

This paper presents a dynamic computational general equilibrium model in which expectations regarding future prices can be varied systematically. The model is employed to evaluate how expectations influence the effect of long-run tax policy changes. Under policies (like a consumption tax) that reduce rates of return over time, individuals with perfect foresight save less than individuals with myopic beliefs. This is because consumers with foresight are better able to anticipate the lower returns. Lower saving means that existing distortions due to capital taxes are not offset as much, so that welfare gains are smaller under perfect foresight.
