Heterogeneous beliefs with herding behaviors and asset pricing in two goods world

We construct a incomplete information equilibrium model with heterogeneous beliefs and herding behaviors to identify their joint effects on the dynamics of asset prices. Herding behaviors make investors revise some of their estimations about expected growth rates of goods streams toward to the other one’s by a manner of weighted average of their own forecast and the other’s. As we expected, herding behaviors generate influences on the Radon Nikodym derivative, that is so-called “sentiment” as in Dumas et al. (2009), and in turn not only impact the dynamics of asset prices but also generate influences on investors’ survivals. We also show that introducing heterogeneous beliefs with herding behaviors permits to explain both the Backus–Smith puzzle and the mixed results about the influences of herding behaviors on asset prices. Moreover, we uncover that herding behaviors have positive influences on stocks’ risk premiums.     

预约定价制度适用于我国的成本悖论解析

实行预约定价制度可以较好地解决转让定价滥用和国际双重征税或不征税问题,提高税务部门工作效率。为了调查预约定价制度在我国的可行性,在对预约定价制度实行的基于信息、客体、国际税收合作、转让定价调整方法和事后监控的成本悖论进行具体分析的基础上,得出预约定价制度必须与传统的事后税收监管相结合,才能有效解决转让定价问题的结论。     

需求不确定下多产品动态定价模型研究

制造商的多产品动态定价问题要考虑原材料的采购、多种产品的生产制造、库存,以及处理下游订单等的成本和未满足的需求及运送的前置时间。通过引入时空网络,建立使制造商期望利润最大的动态定价数学模型,实例分析表明,制造商期望利润最大化的最优价格、最优产品生产量与最优库存量能,是制造商制定合理的生产计划的决策依据。

Cross-sectional quantile regression for estimating conditional VaR of returns during periods of high volatility

Evaluating value at risk (VaR) for a firm’s returns during periods of financial turmoil is a challenging task because of the high volatility in the market. We propose estimating conditional VaR and expected shortfall (ES) for a given firm’s returns using quantile regression with cross-sectional (CSQR) data about other firms operating in the same market. An evaluation using US market data between 2000 and 2020 shows that our approach has certain advantages over a CAViaR model. Identification of low-risk firms and a reduction in computing times are additional advantages of the new method described.     

Asset pricing and energy consumption risk

This paper proposes energy consumption in the US as a new measure for the consumption capital asset pricing model. We find that (i) industrial energy growth produces reasonable values for the relative risk aversion coefficient and the implied risk-free rate; (ii) compared to alternative consumption measures, industrial energy performs well in explaining the cross-sectional variation in stock returns with the lowest implied risk aversion and pricing errors; (iii) the industrial energy consumption risk model performs equally well as the Fama–French three-factor model in the cross-sectional asset pricing tests; and (iv) total energy consumption risk is priced in the presence of the Fama–French factor risks.

Strategic nonlinear pricing

The objective of this paper is to examine the role of nonlinear strategies in a standard oligopoly framework. We demonstrate that nonlinear pricing may indeed emerge as an equilibrium strategy, but only when firms produce differentiated products, when one firm retains market power due to a cost advantage, or as part of an equilibrium in mixed strategies. In addition, we examine the role of nonlinear pricing in a spatial-competition framework. Our main conclusion is that in highly competitive markets, nonlinear pricing strategies are not likely to emerge as an equilibrium.     

Hotel revenue management and the Internet: The effect of price presentation strategies on customers’ willingness to book

A decision that is intrinsic to the application of hotel best available rate (BAR) pricing is how to present the BARs for individual nights within a multiple-night stay to prospective hotel guests. We discuss two alternative price presentation strategies, a blended and a nonblended rate approach, and examine their effect on customers’ willingness to pay in the context of Internet-based reservation requests. Study findings indicate that a nonblended rate presentation approach generates higher willingness to book ratings than a blended rate presentation approach. Furthermore, when it comes to nonblended rates, familiarity with BAR pricing moderates the effect of rate sequence on customers’ willingness to book.
