中日股票市场发行制度比较研究

股票发行制度是一国资本市场的准入制度,对股票市场的健康发展起着重要作用。由于历史条件和经济环境的影响,中国和日本的股票市场规模及效率不同,所以其发行制度也存在很大差异。分析表明,这些差异主要体现在发行审核体制、信息披露制度和发行定价这3个方面,中国在完善股票市场发行制度方面应该关注这些方面的深远影响。

The Effect of Pricing and Advertising on Customer Retention in a Liberalizing Market

This study investigates the drivers of customer retention in a liberalizing market. The authors address key retention issues that allow them to contribute to existing retention research in several critical ways. They (1) examine the effects of pricing and mass advertising, (2) account for (new entrants) competitors' actions, (3) investigate the dynamic impact of marketing tactics, and (4) study the proposed relationships in a market recently opened to competition. Using longitudinal data for a sample of 650 mobile phone consumers and a split-population hazard model that accounts for the notion that some customers are never at risk of defection, the authors show that both the focal firm's (incumbent) and the competitors' price and mass advertising exert a significant influence on the probability of terminating an existing incumbent relationship. They find that the relationships between marketing variables and retention are not static but vary over time. Price is generally less effective in the early stages of market liberalization, which suggests that customers become more price sensitive in later stages. Finally, the study findings can have important strategic implications on designing customer management and marketing resource allocation strategies, as well as on providing a competitive regulatory framework in liberalizing markets.     

The dark side of financial innovation: A case study of the pricing of a retail financial product

The offering prices of 64 issues of a popular retail structured equity product were, on average, almost 8% greater than estimates of the products' fair market values obtained using option pricing methods. Under reasonable assumptions about the underlying stocks' expected returns, the mean expected return estimate on the structured products is slightly below zero. The products do not provide tax, liquidity, or other benefits, and it is difficult to rationalize their purchase by informed rational investors. Our findings are, however, consistent with the recent hypothesis that issuing firms might shroud some aspects of innovative securities or introduce complexity to exploit uninformed investors.     

Uniform or spatially differentiated? Pricing Strategies for Information Goods under simultaneous and sequential decision-making in multi-market context

Product pricing has been one of the central issues in the field of marketing and consumer services for managers and researchers alike. However, pricing of information goods has not been paid much attention in literature. For information goods the marginal costs of production and transportation of information goods (online movies, video games, etc.) is almost zero. Hence, the pricing decisions need to be thought of purely in competitive profit maximizing terms. This paper proposes mechanisms for managers to evaluate and base their pricing decisions on rational frameworks that takes into account various situations when they enter a new market and when they are incumbent in a new market. This paper addresses the research gap of spatially differentiated pricing strategy for information goods that has not been studied in literature so far. We create stylized theoretical models under both, sequential and simultaneous decision-making conditions. We determine the equilibrium price and the equilibrium profit for the two firms for each of the four possible scenarios based on their pricing strategies. Our analysis reveals that the dominance of one pricing strategy over the other depends on product differentiation factor capturing joint effect of the product substitutability and consumer's price sensitivity under sequential decision making and the market size along with consumer's price sensitivity for simultaneous decision making. As an extension, we propose a generalized model demonstrating the uniform and spatially differentiated pricing strategies of the firms under simultaneous and sequential selection for multiple domestic and international markets.     

Risk averse retail pricing with robust demand forecasting

Good demand estimates are the key to effective pricing decision-making. However, they are subject to a high degree of uncertainty due to various factors that are unpredictable or difficult to model, thus making pricing decisions risky. This research provides a simple proposal for a robust optimization methodology that incorporates both demand uncertainty and the decision maker's degree of risk aversion. Uncertainty is explicitly considered for two coefficients of a linear demand function, price expressions are derived, and a criterion is proposed for defining the degree of risk aversion. The resulting model is also applied to an exponential demand case to better reflect a more realistic retail setting.     

F-F三因子资产定价模型的扩展及其实证研究

针对中国证券市场的特征,本文引入会计指标市盈率、技术指标换手率,对标准F-F三因子模型进行了不同层面的改进。实证结果表明,标准F-F三因子定价模型基本能解释中证100样本股相应组合的周回报率,但效果不是很好;换手率高低对组合收益率的解释能力并不优于标准模型,但换手率与市盈率同时进入模型,却能有效提高周收益率的解释,是一个基本适合中国股市的资产定价模型。     

Time-varying risk in the German stock market

This paper compares two specifications of the Capital Asset Pricing Model for a sample of German stocks. The specifications generate time-varying first and second moments by conditioning on past information. This explicit modelling of the time series behaviour of risk allows us to characterize the driving factors of variances and covariances of returns. In addition to a variety of diagnostic tests we evaluate the validity of the one-factor restriction in the CAPM. The main findings are that risk is time dependent and very variable and also that more than one factor is needed to fit the data set.     

Optimal Returns Policy under Demand Uncertainty

Multiple categories of retail products suffer limited shelf life, demand uncertainty, and, in some cases, long lead times. To provide retailers with an incentive to increase the stocking quantity of such products, manufacturers may offer an option to return unsold items at wholesale or less than wholesale prices. This article extends the additive price-dependent demand model in three ways. First, partial returns are optimal for the manufacturer but do not induce higher stocking quantities compared with when the manufacturer offers no returns. Second, in terms of the effect of investment in demand-enhancing activities, when retailers invest, they set higher resale prices, but an optimal partial returns policy still does not induce higher stocking quantity, whereas when manufacturers invest, the optimal returns policy induces higher stocking quantity. Third, when the manufacturer and retailer have different expectations of demand uncertainty, the retailer's estimate influences the expected profits for both, whereas the manufacturer's estimate has a major impact on its profits only.
