高科技产业新产品定价策略研究——基于系统动力学

新产品的开发对于高科技产业来说日趋重要，需要不断的努力和巨大的市场意识，系统的价格监测对于分割市场和合理配置资源具有很重要的意义，企业应该认真考虑以确定最优定价策略。本文在不同竞争环境下建立了不同定价策略对企业综合影响的系统动力学模型，在对模型模拟分析的基础上，研究了不同定价策略对企业的影响。结果表明，高科技产业新产品采用撇脂定价策略相对于渗透定价策略具有更大的优越性，并根据企业实际的定价能力，适当地延长撇脂时间和增大撇脂价格可以带来更大的经济效益。     

Efficient local IV estimation of an empirical auction model

In this paper we examine semiparametric efficiency bounds and efficient estimators for the case of a linear local instrument variable (LIV) model under the assumptions studied in Abadie et al. (2002). We apply the semiparametrically efficient estimation method to analyze the relation between bid dispersion and early bidding in an online auction dataset, which is collected from a natural experiment conducted in Nekipelov (2007). The results confirm the theoretical findings developed in Nekipelov (2007). The semiparametric efficient estimation procedure substantially improves the statistical significance of the effect of jump bidding on bid dispersion.     

Valuing traceability of imported beef in Korea: an experimental auction approach*

The major objective of this study is to estimate Korean food shoppers’ willingness to pay (WTP) for imported beef with traceability. We use an experimental elicitation method, the random nth price auction, to identify consumers’ valuation for traceable imported beef. We also analyse the effect of different types of information on these valuations. Results indicate that consumers are generally willing to pay a 39 per cent premium for the traceable imported beef over similar beef without traceability. Results also suggest that in contrast to the insignificant effect of positive information, negative and two‐sided information about traceability significantly reduces WTP.

优化我国证券收益所得课税的思考

我国经济和证券市场的高速发展对现行证券税制提出更高的要求。因此,我国证券税制的改革应循着这样的道路:进一步完善现行税制,并与国际惯例接轨;调节收入分配关系,更好地体现公平原则;打击短期投资行为,鼓励长期投资;尽快解决重复征税问题,使之成为推动证券市场健康发展的动力。     

胜利油田滨二块双低单元综合治理方案及经济评价

在对胜利油田滨二块砂二段油藏的地质特征、注采井网、开发现状进行精细研究的基础上，科学分析了单元双低（采油速度低、采出程度低）的主要原因，提出了一套技术先进的双低治理方案，采用“增量法”进行经济评价表明，该方案不仅技术可行，而且具有较好的经济效益，是低产老油田恢复能力的好办法。     

中国经济的发展阶段研究

经济发展是指随着经济增长而出现的经济、社会和政治结构的变化。本文将经济发展研究分成收入、城市化、产业、消费和科技五个方面,运用多种参数指标,立足世界经济的未来与过去,得出我国经济发展的阶段、特点和规律。作者根据国内外关于一国经济发展阶段和中国发展阶段的现实,选择工业化和城市化作为核心指标,对比美国经济发展历程,得出我国经济发展处于“工业化和城市化‘双中期’区间”的判断;并在此基础上分析了“‘双中期’区间”最新时点的关键特征;概括出我国经济发展的双重性规律,提出了中国经济发展战略思路及政策建议。     

An experimental investigation of soft price caps in uniform price auction markets for wholesale electricity

This paper presents the results from an auction experiment using industry professionals and student participants who compete in a simulated wholesale market for electricity. Motivated by the intervention by FERC in response to the “meltdown” of the California spot market, we investigate the effect of including a “soft” price cap in a uniform price auction as a means of mitigating high prices. When prices are driven above the soft cap, offer curves become flat, in contrast to the hockey stick shape observed in a typical uniform price auction for electricity. This flat offer curve leads to market prices that are relatively insensitive to both generation costs and demand reductions.
