基于理性预期条件下的宏观经济政策有效性分析

理性预期理论是最近二十几年在西方发展起来的一个新兴学派,它的发展在一定程度上改变了现代西方经济学的分析方法和理论结构。本文从理性预期学派的起源和理论基础出发,以理性预期的视角探讨现代宏观经济体系中微观层面上个体行为与宏观层面上经济行为之间的内在联系,认为政府在微观经济主体具备良好理性预期能力的前提下,宏观经济政策对经济的调节是有限的,政府必须充分尊重并合理引导微观经济主体的预期,才能不断提高宏观经济政策的效用。     

对理性模式的反思

在管理过程中,无论是政策的制定者还是政策的执行者无不都在追求理性地做出行动,希望在"理性"的驱使下确保自己能够正确、科学而有效地实现其活动目标,并因此建立起"理性模式"来指导管理活动。但是,人的理性是有限的,因此,在归纳人类理性行为机制基础上而建立起的"理性模式"也是具有一定的局限的,对这些局限进行充分的认识对于管理活动来说意义不可小觑。     

The house price determination process: Rational expectations with a spatial context

Applying the rational expectations hypothesis, this essay models the current value of a house as the conditional expectation of the discounted stream of housing services accruing to the owner of the house. The value of housing services is determined by neighborhood effects as well as the physical attributes of the property itself. In the existing hedonic literature, future transactions have not been utilized to describe neighborhood effects. The rational expectations asset pricing model in this study accounts for expected future neighborhood effects as well as observed current neighborhood effects. The reduced form of the rational expectations model is a spatial autoregressive (SAR) model with two spatial lags. After employing the generalized method of moments (GMM) in estimating the spatial asset pricing model, I find that both expected future transactions and prior transactions in the neighborhood are significant. The inclusion of expected future transaction prices in the neighborhood takes into account the influence of expected changes in the community and factors these potential changes into the current house price. This is consistent with forward-looking households. The forward-looking model generates superior out-of-sample prediction performance relative to both the conventional hedonic model without considering neighborhood effects or the standard spatial hedonic model including only past transactions.     

Consumption dynamics under information processing constraints

This paper studies how “rational inattention” (RI)—a type of information processing constraint proposed by Sims [Sims, C.A., 2003. Implications of rational inattention, Journal of Monetary Economics 50 (3), 665–690]—affects the joint dynamics of consumption and income in a permanent income model with general income processes. Specifically, I propose an analytical approach to solve the multivariate permanent income model with RI and examine its implications for optimal consumption, saving, and welfare. It is shown that RI can affect the relative volatility of consumption and provide an endogenous propagation mechanism that disentangles the short-run and long-run responses of consumption to exogenous income shocks. I also explore how aggregation reduces the impact of the RI-induced endogenous noise on consumption and thus increases the smoothness of aggregate consumption. Finally, I compare RI with four alternative hypotheses (habit formation, signal extraction, robustness, and inattentiveness) by examining their implications for the joint behavior of consumption and income.     

再融资监管促进企业理性投资了吗？——来自中国上市公司的证据

本文以2007-2016年的A股上市公司为样本,实证检验中国再融资监管制度是否促进了企业的理性投资行为。研究发现:上市企业投资决策符合资本成本约束的理性准则,表明中国权益市场中存在普遍的市场约束力量;但企业再融资后投资理性程度明显降低;对监管失效的原因分析表明,企业投资理性程度下降受到事前融资动机和事后募资投向变更的影响:监管规则对事前再融资动机缺乏有效把控,导致再融资资格出现错配;而对事后募资用途的监管不严,则导致部分企业对募集资金的用途进行随意变更,使得企业投资理性程度降低。研究结论为完善企业投资决策自治机制、优化权益再融资监管、促进资本市场改革提供了实证依据和一定的现实启示。     

科学提升中国金融业“走出去”品质——兼论推进人民币理性国际化的路径选择

文章认为中国走出去分为三个层次,一是产品走出去,二是企业走出去,三是金融走出去。金融走出去最关键的是人民币走出去,即实现人民币的全球化。在后危机时代,金融是实现战略转型的重要手段,而且是提升我国走出去品质的战略抓手。我们要真正提升金融走出去品质,一要优化金融走出去的载体结构,做大做强金融机构;二要优化金融走出去的产品结构,提升金融知识产权状态;三要提高人民币的社会主义运用水平,科学推进人民币理性国际化。     

中国农村消费的刺激机制与理性回归

近几年,我国农业与农村基础设施投资不断增加促进了农业生产率的提高,加速了农村产业的转型。现代农业的逐步实施、农村环境的改善和保障体系的初步建成,使得农村消费增长的内在条件基本成熟。然而,刺激农村消费增长必须建立适合中国特色的理性消费机制,促进农民收入稳定增长,理性回归才能更好地保障农村经济可持续发展。     

关于中国现时期需求不足的理性分析与对策思考

本文对我国现时期出现的需求不足问题进行了理性分析,并进一步从理论和实践的结合上论证了产生这一问题的主要原因是：通货紧缩、普遍性供给过剩、消费预期恶化。本文的宗旨是为政府采取治理需求不足政策提供理论根据。     

Weakly rational expectations

Aumann and Drèze (2008) characterised the set of interim expected payoffs that players may have in rational belief systems, in which there is common knowledge of rationality and a common prior. We show here that common knowledge of rationality is not needed: when rationality is satisfied in the support of an action-consistent distribution (a concept introduced by Barelli (2009)), one obtains exactly the same set of rational expectations, despite the fact that in such ‘weakly rational belief systems’ there may not be mutual knowledge of rationality, let alone common knowledge of rationality. In the special case of two-player zero-sum games, the only expected payoff is the minmax value, even under these weak assumptions.     

理性预期与能源投资——基于中国碳减排承诺的自然实验

引入宏观经济学的理性预期分析框架来评估未来碳减排承诺如何影响当期的能源投资行为具有重要意义。能源项目投资规模大、持续时间长、不可逆性强,使得投资者在决策时会尽可能地纳入影响未来收益和成本的信息。本文将中国碳排放权交易市场试点政策与发电行业投资行为相结合,理论分析和实证检验了政府规划和实施的碳排放权交易市场试点政策如何影响企业的理性预期作用于当期发电技术项目投资,结果表明,碳排放权交易市场试点政策在规划期会促使企业相对提高试点地区低排放发电技术项目投资,特别是相对提高了这些地区低排放火力发电技术项目投资。碳排放权交易试点政策正式实施之后,企业降低了政策试点地区的高排放发电技术项目投资的实际利用水平。这一发现说明环境管制政策在正式实施之前的规划期,会对企业的投资行为产生预期管理效应,通过释放减排政策信号,促使企业先验地调整能源投资决策,以适应未来减排承诺目标。
