流动性视角下的非流通股定价策略分析

金融市场上的流动性对金融资产定价有重要作用。在Longstaff模型的基础上对“卖掉持有股票的权利”进行定价,可得出股票的流动性价格,进而得到非流通股的价格。通过分析可知非流通股的价格是禁售期的减函数,是流通股的增函数;股票的价格波动率越大,贷款利率与无风险利率的差越大,非流通股的价格是就越低;反之,非流通股的价格就越高。以我国股票市场的相关指数进行验证,上述结论依然成立。     

体制性约束、双重失衡与政策权衡——全球金融危机挑战与中国的财政政策选择

在中国经济发展总量得到实质性提高的今天,重新实施积极财政政策,其着眼点不仅在于应对这次全球金融危机对中国带来的冲击,更重要的是利用这次契机化解中国经济发展长期存在的体制性约束,转变中国经济增长方式,实现经济的稳定和可持续增长。财政政策也因此面临着如何权衡缓解经济危机冲击和实现经济长期稳定发展的问题。从中国财政政策实践来看,单纯的反周期调节可以拉动经济走出低迷,却无力恢复经济的自主增长动力,应对当前中国经济出现的长期内部失衡更需要财政政策着眼于整个改革过程和整个经济结构。本文基于金融危机背景下中国面临双重失衡的判断,提出了中国经济发展内外失衡的概念,并探讨了两种失衡条件下财政政策的运行原理,同时以转轨背景下中国所面临的体制性约束为限制条件,考察了财政政策困境的现实根源,并给出了财政政策权衡的政策涵义。     

Joint pricing and design of urban highways with spatial and user group heterogeneity

This paper addresses the joint optimization of capacity investments and toll charges imposed on multi-group users in monopolistic private highways within general road networks. A game-theoretic formulation is provided that leads to a nonconvex bilevel program. The proposed modeling framework handles several complex issues raised in realistic applications, such as regulations on the levels of tolls and service, and the discrete nature of highway capacity, using a genetic optimization technique. Real-application results show the importance of considering the spatial heterogeneity of prices, and the tradeoff between investments and pricing strategies in regulated private highways.     

Sector level cost of equity in African financial markets

This paper assesses the effectiveness of Liu (2006) metrics in measuring illiquidity within a multifactor CAPM pricing model. Costs of equity are estimated using this model for the major sectors within Africa's larger equity markets: Morocco, Tunisia, Egypt, Kenya, Nigeria, Zambia, Botswana and South Africa. In all countries, the cost of equity is found to be highest in the financial sector and lowest in the blue chip stocks of Tunisia, Morocco, Namibia and South Africa. At an aggregate level, Nigeria and Zambia have the highest cost of capital.     

Grey Power: An Empirical Investigation of the Impact of Parallel Imports on Market Prices

The persistence of price discrimination across international markets with falling costs of unofficial importing is both paradox and policy concern. E-commerce facilitates a “grey” market in parallel imports, particularly for high-value goods such as electronics. This paper explores the impact of unofficial imports on price using a panel of product markets mediated via an Internet shopbot. It finds the presence of an import model lowers prices across the market. However, unlike the refurbished model it is not simply an inferior substitute. The import price discount increases over the model life cycle, suggesting that model-specific preferences fall as each model ages.

存贷款利差定价分析

存贷款利差合理水平取决于违约率、损失率、流动性风险、资本缓冲与信贷类资产的比率,以及无风险基准利率。银行业内部管理水平不足和存贷款市场的总体失衡会导致利差水平扩大和提高。我国当前的存贷款利差水平相对于其合理水平而言过低,不仅不利于银行业长期健康发展,而且也对整个金融体系累积了巨大的体系性风险。     

倒边盖挖逆作法基坑支护结构可靠性分析

为了解决采用标准Monte Carlo法计算复杂基坑工程上常见小概率失效,导致计算效率低的问题,以南京市湖南路地下商业街工程为工程背景,首先,将随机响应面法与基坑工程三维模型相结合,求解极限功能函数的响应面方程,并用标准Monte Carlo法计算失效概率和可靠指标,探讨采用倒边盖挖逆作法作为基坑支护结构施工方法的可行性;其次,基于该响应面方程,以土体的弹性模量为随机变量参数,采用马尔可夫链蒙特卡罗子集模拟法(MCMC子集模拟法)计算基坑支护结构的失效概率,并与标准Monte Carlo法结果进行对比分析。结果表明：当支护结构最大侧移控制指标为25 mm时,计算得到的可靠指标均大于4.6,即采用倒边盖挖逆作法施工过程中基坑是安全的;10万次和50万次标准Monte Carlo法计算得到的失效概率均为零,说明对于标准Monte Carlo法,在计算小概率失效问题时10万与50万的样本量是不足的;而MCMC子集模拟法用2.98万个样本计算出的结果与标准Monte Carlo法采用100万个样本计算的结果相对误差仅为1.7%,表明MCMC子集模拟法对于小概率失效问题求解的优势。所提算法在一定...     

铁矿石国际贸易定价权与议价力的博弈分析

文章通过对铁矿石国际贸易定价的博弈分析,发现定价权能够带来先动优势,因而买卖双方内部寡头都有竞争定价权的动力,且竞争的相对强度决定了各自的议价力大小;在铁矿石国际贸易中,定价权竞争具有"弱者优势"效应,但其作用有限.因此,为应对铁矿石国际贸易持续上涨的压力,我国钢铁企业应综合考虑定价权竞争与议价力的提升,并以改变买卖双方定价权竞争的相对强度为目标设计博弈对策     

浅议电子商务专业的准职业环境实训

在传统的电子商务模拟实训中,由于脱离了市场和社会,使得学生重视交易的成功,忽视了交易的成本,培养的学生拥有了熟练的操作技能,但缺乏相应的市场意识。准职业环境实训将模拟实训和市场有机地结合起来,既加强了学生操作技能的训练,又增强了学生的商务意识,提高了学生的综合素质。
