On the Treatment of Anticipated Shocks in Models of Optimal Control with Rational Expectations: An Economic Interpretation
提出一种基于价格理论基本概念的通用启发式方法,处理完全预见模型中预期变化的问题,并应用于状态变量预期冲击的例子,说明标准影子价格连续性条件失效时该方法仍适用。
The authors suggest a general, heuristic method, based on elementary notions of price theory, for dealing with the question of anticipated changes in models of perfect foresight. The method is illustrated for the case of anticipated shocks to the state variable; in this context the standard "shadow price continuity condition" fails, while the method presented here applies. After presenting the general solution, it is used to analyze various examples of preannounced changes. Copyright 1990 by American Economic Association.
