摘要

这些ppt幻灯片是我为“金融市场:关注与挑战”全国研讨会(印度,盖泽拉巴德;(2009年2月21-22日),并从资本市场的社会功能出发。在探索这一基本维度时,幻灯片倾向于凯恩斯主义对资本市场的看法,与现代金融经济学所支持的观点相反,现代金融经济学将市场概念化为有效的,“充分反映了所有相关信息”。他们表达的观点是,投资者没有根据长期基本信息采取谨慎行动,而是受到了“Snap和抢椅子游戏”的短期主义者的对待,并乐此不疲。在监管方面,这意味着一些维持对实体前景的预期形成过程的制度安排(主要是估值和评级实践)已经暴露出不利的一面,超出了它们的相关性,迫切需要被一种新的经济衡量、评级和资本市场估值的架构和方法所取代。根据这一观点,本文提出并简要探讨了一些可以融入新制度的制度和方法特征,包括建立一个特定行业评级机构的公共网络的建议。据推测,资本市场旷日持久的危机是对微观经济信息和预测提供者的旧架构的不可避免的不信任,以及对今后可能来自他们的分析运动(无论是否合理)的任何东西的不信任。随着危机前的热情预期消失殆尽,由此留下的微观经济预期真空才是监管机构应该关注并试图遏制的地方。要做到这一点,必须首先对市场行为和现代金融经济学范式中隐含的严重危险有一个正确的新认识,从而重新审视形势。后者的大厦可能会倒塌,因为大规模的流动性效应和投机的后果可能会让人们对这种范式的基石的迷恋付之一振。在事件发生之前推测替代结构是愚蠢的,但任何关于“资本理念”的新理论观点都应该提供它们与实际经济领域的明确联系,并直接纳入可持续宏观经济发展的政策。“微观经济市场行为实践的宏观经济基础”是对资本市场理论和监管所需要的愿景的陈词滥调,但它很可能会给资本市场活动带来新的活力。

Pricing and Valuation on the Capital Markets: How to Clear the Fallout?
These ppt slides represent my presentation prepared for the National Seminar on Financial Markets: Concerns & Challenges (Ghaizerabad, India; Feb 21-22, 2009) and set off with the vision of social functions for the capital markets. In exploring this basic dimension, the slides lean on the Keynesian vision of capital markets in opposition to one espoused by the Modern Financial Economics where markets are conceptualized as efficient and 'fully reflecting all the relevant information'. The opinion expressed is that instead of taking care to act on long-term fundamental information investors have been treated, and eaten with pleasure, a short-termist diet of 'Snap and Musical chairs'. In regulatory terms, it means that some institutional arrangements upholding expectation-formation processes about the prospects of entities (mostly valuation and rating practices) have revealed themselves in unfavourable light, outlived their relevance and are in dire need of replacement by a new architecture and methodology for economic measurements, rating and valuation on capital markets. Following this view, some institutional and methodological features that can be weaven into the new system are suggested and briefly explored, including the proposal for creating a public network of industry-specific rating agencies. It is speculated that what would make for a prolonged crisis on the capital markets is the inevitable distrust toward the old architecture of micro-economic information and forecast providers and to anything that henceforward is likely to come from their analytical motions (whether sensible or not). With pre-crisis enthusiastic expectations gone out of the window, the vacuum of micro-economic expectations which was thus left is the place which regulators should look into and try to contain. This can't be done without looking at the situation anew by first embracing a proper new vision related to the market behavior and recognition of the serious danger implicit in the Modern Financial Economics paradigm. The edifice of the latter may collapse, as the enormous scale of liquidity effects and fallout from speculation may put paid to the infatuation with the building blocks of that paradigm. It is yet foolhardly to speculate on the replacement structure before the event, but any new theoretical view of 'capital ideas' should provide for their explicit linkage with the real economic sphere and direct incorporation of the policy for sustainable macroeconomic development. "Macroeconomic foundations for micro-economic market behavior practices" is a hackneyed shibboleth of vision for what capital markets theory and regulation needs but one which may well come to give fresh boost to the vigor of capital market activities.
