| Summary: | 碩士 === 國立中山大學 === 經濟學研究所 === 92 === The presented thesis has closely examined the discussion on policy assignments that are restricted on an open macroeconomic model; very little reference has focused on a closed macroeconomic model. As we know, Ramirez (1986) is the first person who has applied policy assignment to a closed macroeconomic model. But Chang and Lai have clearly proved that Ramirez''s model is not appropriate for policy assignment, and a way to redeem the problem is to introduce policy instrument to aggregate supply side. Also, this thesis is going to focus on, instead of introduced the policy instrument to aggregate supply side, use system endogenous on aggregate supply function. Could this kind of correction redeem the flaws made by Ramirez? Hence, this thesis would apply the reality intertemporal substitution effect of labor to subsume an aggregate supply side, then discuss the relationship on policy assignment that is between policy instrument and policy target that would derive the conclusion as below:
When a model does not include the intertemporal substitution effect of labor, it degrades to a Ramirez''s model (1986) and cannot be used for policy assignment. On the other hand, a model including intertemporal substitution effect of labor remedies the flaws in Ramirez''s model (1986) and can be used for appropriate policy assignment assuming that government spending is in complement with private spending.
