This paper proposes an asymmetric autoregressive conditional duration (ACD) model, which extends the ACD model of Engle and Russell (1998). The asymmetry consists of letting the duration process depend on the state of the price process. If the price has increased, the parameters of the ACD model can differ from what they are if the price has decreased. The model is applied to the bid-ask quotes of two stocks traded on the NYSE and the evidence in favour of asymmetry is strong. Information effects (Easley and O'Hara 1992) are also empirically relevant. As the model is a transition model for the price process, it delivers `market forecasts' of where prices are heading. A trading strategy based on the model is implemented using tick-by-tick data.While remaining responsible for any error in this paper, the authors would like to thank R. Anderson, G. Le Fol, C.

Global warming is currently an important item on most nationalenvironmental agendas. In many countries, coal-fired electricity generatingstations represent an important source of greenhouse gases. We examinehow regulations to curb emissions affect public utility pricing regulationwhen regulators act non-cooperatively. We show that, when there is limitedinformation on fixed abatement costs, an environmental regulator prefersan emission tax over an output tax or a lump sum environmental tax. Thepublic utility regulator prefers the lump sum tax regime. 相似文献

Summary. A model that includes the cost of producing money is presented and the nature of the inefficient equilibria in the model
are examined. It is suggested that if one acknowledges that transactions are a form of production, which requires the consumption
of resources, then the concept of Pareto optimality is inappropriate for assessing efficiency. Instead it becomes necessary
to provide an appropriate comparative analysis of alternative transactions mechanisms in the appropriate context.

The paper reexamines the conventional results relating to inflow of foreign capital, removal of protectionism and structural reform programmes, in a small open economy in terms of a two-sector general equilibrium model with an informal sector. The paper shows that in the presence of labour market distortion and a protectionist policy, inflow of foreign capital may be desirable irrespective of the pattern of trade of the economy due to its favourable impact on welfare. But the welfare implications of tariff reductions and/or structural adjustment programmes, such as deregulating the formal sector labour market, depend crucially on the economy's trade pattern. The paper provides an answer to the question as to whether in a developing economy labour market reform and tariff reform should go hand-in-hand or whether one should precede the other for welfare improvement.

汇率决定理论的新近发展:文献综述 总被引:15,自引:0,他引:15
传统汇率决定理论对于现实经济中汇率实际变动情况的解释能力十分低下.20世纪80年代以来,学术界不断寻求突破,以期为汇率如何决定这一基本命题提供更为合理的解释.在这一过程中,不断有新的文献出现,从不同的方面对传统的汇率理论进行补充、发展和替代.鉴于此,本文试图对汇率决定理论的新近发展进行梳理和介绍,借以为国内经济学界研究汇率决定问题提供一个理论参考. 相似文献

Summary. In order to explain in a systematic way why certain combinations of market, financial, and legal structures may be intrinsic to certain capabilities to exchange real goods, we introduce criteria for abstracting the qualitative functions of markets. The criteria involve the number of strategic freedoms the combined institutions, considered as formalized strategic games, present to traders, the constraints they impose, and the symmetry with which those constraints are applied to the traders. We pay particular attention to what is required to make these strategic market games well-defined, and to make various solutions computable by the agents within the bounds on information and control they are assumed to have. As an application of these criteria, we present a complete taxonomy of the minimal one-period exchange economies with symmetric information and inside money. A natural hierarchy of market forms is observed to emerge, in which institutionally simpler markets are often found to be more suitable to fewer and less-diversified traders, while the institutionally richer markets only become functional as the size and diversity of their users gets large.Received: 5 June 2003, Revised: 18 November 2003, JEL Classification Numbers:

货币政策的传导机制不是唯一的,金融市场的种种特征造成了货币政策传导的多样性,股票市场中的货币政策传导就具有独特的规律,在不与银行信贷的创造机制相连的前提下,信贷资金和股市资金的沟通是合理的,目前中国信贷市场和股票市场之间千丝万缕的关系,并没有为货币政策传导创造更加有效的机制基础,股票市场还不能成为货币政策的有效传导渠道。 相似文献

资本市场变迁及运行效率是中外学者研究的重点,形成了许多理论流派,其中信息空间理论为资本市场制度变迁提供了新的分析框架。同时,中国资本市场正处在发展建设之中,亟需有效的理论指导其发展。然而,中国资本市场的不完备性和特殊性导致诸多理论的应用存在局限性。而信息是各理论流派研究的核心,只是角度和侧重点不同,故信息空间理论可为研究资本市场变迁和制度选择提供新的研究思路。 相似文献
