At the most general level, policymakers in open economies face a macroeconomic trilemma. Typically they are confronted with three typically desirable, yet contradictory,
objectives:
1. to stabilize the exchange rate;
2. to enjoy free international capital mobility;
3. to engage in a monetary policy oriented towards domestic goals.
Because only two out of the three objectives can be mutually consistent, policymakers must decide which one is to give up. This is the trilemma.
However, fluctuating exchange rates cannot insulate economies from the global financial cycle, when capital is mobile. The Trilemma morphs into a dilemma - independent
monetary policy are possible if and only if the capital accounts is managed, directly or indirectly, regardless of the exchange-rate regime.
This implies that gross flows, particular credit flows, are of great importance for financial stability and have to be monitored carefully. It is also only by looking at
gross flows and gross cross border positions that one can keep track of currency and maturity mismatch.
3.今天你阅读到的有价值信息的自我思考点评感想
形成系统理论的过程是由繁到简的过程,而将理论应用到实际的过程则是由简入繁的过程。本节比较详细地描述了作者带领的小组,在开发隐含二叉树模型过程中的思考过程,及对于物理学规律与金融实践模型应用的相通之处,与相互之间的区别。目的当然是为了管理风险:如果科学家的模型在1979年左右就已经对1987年股灾式的下跌进行研究并且了解决方案的话(给出的解决方案是:“在市场上寻找那些市场价格与我们模型计算出来的价格严重偏离的期权。这样,他们就可以通过买入那些价格明显被低估的期权而卖出那些价格被高估的期权,以期这些价格出现偏离的期权最终能够恢复到我们模型计算出的价格,从而获得利润。”)。那么,对于期权定价模型的研究,并且随时根据市场出现的情况对于未来价格变化的情况进行几率性的预测就变的非常重要了,这是即是对冲风险的基本手段(尤其是在其他投行都这样操作时)。
作者使用了大量的物理专业词汇,估计其他专业的同行看了都会感到头痛,实际上逆散射的研究方法可以通过本书的描述大致了解到。散射过程是大家在中学物理和化学课都学到过的,逆散射则是将散射的过程进行还原,从而找到在这个过程中出现的各种影响因素对于结果可能造成的影响。
连我都感觉快看不懂了。还真是需要深入了解和进一步地熟练。
A股上2700了,能一冲到2800吗?期待中。
