Stochastic Regime Switching and Stabilizing Policies within Regimes
本文描述了一类资产价格体制内的随机稳定政策，可纳入体制转换框架，用于刻画货币当局在固定汇率前的干预行为，且与目标区干预经验证据一致。
This paper describes a class of stochastic stabilizing policies within asset price regimes; that can be easily incorporated into the framework of regime swtiching recently proposed by K. A. Froot and M. Obstfeld. In contrast to previous treatments of market-driven fundamentals within the regime, authorities stochasstically counteract movements in these fundamentals before asset prices reach boundary points. This paper describes how the stabilizing intra-regime intervention policies can be used to characterize the behaviour of monetary authorities before fixing an exchange rate, as in the cases studied by R. P. Flood and P. Garber. An intervention policy within target zone bands consistent with empirical evidence is also a member of this class of policies. Furthermore, the stylized features of these intervention policies may be matched to actual data in a natural way.
