关于完善我国证券市场监管体系的思考

目前中国证券市场监管体系存在监管主体职能不强、监管效率低下水平不高、自律 管理有名无实、证券市场监管法律法规不健全及操作性差等问题,亟需借鉴美国等发达证券市场 的经验,从多方面加以完善,如建立多层次的证券监督体系、加强自律管理、健全配套规则和法 制、健全上市公司治理结构、建立完善的信息披露制度等。

科技产业与市场:需求导向及其互动

计划经济体制向市场经济体制转变 ,促使产业结构调整越来越依赖于市场需求的拉动。市场需求作为科技产业发展的重点选择和导向 ,推动了科技与经济的一体化进程 ,加快了产业结构演变和升级 ,进一步完善了以产、学、研结合为核心的科技产业发展体系 ,进而提高了科技产业在市场经济中的竞争力。本文所要研究的是转型期市场需求与科技产业互动发展的相关问题。从市场需求导向角度 ,就市场需求对科技产业发展的影响进行分析 ,对科技领先的市场特征进行描述 ,并论述了政府对科技产业市场需求潜力的影响。     

市场结构、汇率转嫁与出口

汇率变化是影响出口贸易的重要因素。在传统的国际贸易理论中,虽然对汇率变化影响出口贸易的机制进行了详细分析,但它没有考虑到市场结构的影响。本文从市场结构的角度出发,分析在不完全竞争的市场结构下,拥有市场势力的企业的决策怎样影响到汇率的变动和产品的出口。本文的研究结果表明,在不完全竞争的市场结构下,汇率转嫁是不完全的,因此,只有大的持久的汇率贬值或升值才会对出口贸易量产生明显的效应。

Distributional assumptions and a test of the dual labor market hypothesis

Recent application of the switching regression model to allocate workers into the primary and secondary labor markets is considered to be the best solution to the classification problem of the empirical testing of the dual labor market theory. In such models, normality of the error terms is assumed. This paper adopts the switching regression model to test the dual labor market theory by assuming different distributions of the error terms. The test results strongly support the dual labor market theory regardless of the assumption one makes about the error terms. However, the results indicate that different distribution can lead to different percentage distributions of workers in the two segments. In particular, the normal distribution generates more workers in the primary segment than the non-normal distributions. Therefore, care must be taken not to generalize the type of industries or occupations that fall under the primary and secondary segments.

Asymmetric ACD models: Introducing price information in ACD models

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.
