Buffer Stocks and Naive Expectations in a Non-Walrasian Dynamic Macromodel: Stability, Cyclicity and Chaos
修改了Honkapohja & Ito的库存动态模型,用前期需求而非实际需求定义预期需求,发现凯恩斯失业均衡不变但稳定性条件更宽松,并分析了不稳定系统的混沌行为。
In their pioneering work Honkapohja & Ito (1980) constructed a non-Walrasian macromodel with inventory dynamics. Some of their assumptions are modified in this paper, e.g. the expected demand for goods is defined by previous rather than actual demand. The modified model yields results which are both similar and dissimilar to those of Honkapohja and Ito. For example, the Keynesian unemployment equilibrium remains invariant but the corresponding stability condition becomes milder. The chaotic behavior of the unstable systems is also analyzed.
