Growth uncertainty,generalized disappointment aversion and production-based asset pricing

We study a production economy with regime switching in the conditional mean and volatility of productivity growth. The representative agent has generalized disappointment aversion (GDA) preferences. We show that volatility risk in productivity growth carries a positive and sizable risk premium in levered equity. Our model can endogenously generate long-run risks in the volatility of consumption growth observed in the data. We show that introducing leverage with a procyclical dividend process consistent with the data is critical for the GDA preferences to have a large impact on equity returns.     

基于期权定价理论的风险投资决策

项目评价的传统方法———净现值(NPV)法在应用于风险投资项目时,由于低估了投资价值,往往会使得投资者失去一些有价值的投资机会。结合风险投资的特性,将期权定价理论应用于风险投资决策中,并建立连续及离散两种状态下的决策模型     

对价方式、盈余管理与市场绩效

选取国有企业控制权转移的样本,剖析有偿转让和无偿转让这两种不同对价方式对盈余管理的影响,并对不同的对价方式下控制权转移是否改进了企业的中短期及长期的市场绩效进行经验检验。研究发现：（1）有偿转让控制权的对价方式更易推动上市公司通过操控应计利润调低净资产,提高溢价率,以符合政策要求;（2）在整体上无偿类样本相对于同行业公...     

Mixed logit analysis of trade-off effects between international airline fares and fences: a revenue management perspective

As transportation is essential for tourism development, effectively utilizing its perishable resources has become an important issue. This study aims to analyse the relationship between airline fares and using conditions from the perspective of millennial tourists and taking the Taipei–Tokyo market as an example. The study attempts to show a revenue management practice in the manipulation of homogeneous seat service and give millennial tourists a better understanding of their preferences for ticket choices. We categorize availability of flight, advance booking, ticket validity, and changing conditions as main attributes and develop a stated-preference questionnaire with multiple hypothetical scenarios for respondents to select in the experiment. We effectively collect 390 valid samples for a mixed logit analysis and the results show that all applied attributes are statistically significant. Ticket validity is revealed to be the most important fence with the largest willingness-to-pay value and followed by availability of flight, advanced booking, and changing conditions.     

Pareto-improving social optimal pricing schemes based on bottleneck permits for managing congestion at a merging section

Akamatsu, Sato, and Nguyen (2006 Akamatsu, T., Sato, S., &; Nguyen, X. L. (2006). Tradable time-of-day bottleneck permits for morning commuters (in Japanese). JSCE Journal of Infrastructure Planning 62(4), 605–620.[Crossref] , [Google Scholar]) proposed a first-best pricing scheme based on the concept of bottleneck permits. The scheme allows permit holders to pass a bottleneck at specified times and is shown to be able to minimize social cost. However, the scheme is not always Pareto-improving in that it may harm some drivers. The objective of this study is to design Pareto-improving pricing scheme with bottleneck permits for a V-shaped two-to-one merge bottleneck. First, the paper formulates the morning commute model in the network and describes the arrival time choice equilibrium in the network with merging bottleneck. Secondly, we show that the first-best pricing scheme with bottleneck permits for this V-shaped network does not always achieve a Pareto improvement, with the cost of one group of drivers is increased by the permit pricing, a phenomena akin to the bottleneck paradox of Arnott, de Palma, and Lindsey (1993 Arnott, R., de Palma, A., &; Lindsey, R. (1993). Properties of dynamic traffic equilibrium involving bottlenecks, including a paradox and metering. Transportation Science 27(2), 148–160.[Crossref], [Web of Science ®] , [Google Scholar]). We propose three implementations of bottleneck permits for Pareto-improving: (1) merging priority rule is included in the bottleneck permits scheme by creating different market for each origin; (2) the permit revenues are refunded as monetary compensation to drivers whose cost is increased; and (3) the permit revenues are used to expand bottleneck capacity. For each implementation, we derive their equilibrium solutions and demonstrate that the Pareto improvement is achieved and social cost is decreased by using the permit revenues for expanding the bottleneck capacity.

我国旅游景区门票多目标定价机制研究

传统产品定价研究大都从市场供需出发,以利润最大化来设置产品价格.然而景区门票价格是由市场因素和政策因素共同作用形成,景区门票定价不仅要满足景区经营方的利润最优目标,还应符合景区的生态承栽能力和社会福利目标.文章通过建立景区基于利润最优目标、生态承裁力目标和社会福利最优目标模型,证明了当追求利润最大化目标时,景区应该以产业利润最大化来制定门票价格;当景区生态承载能力低于产业利润最优的游客数量时,票价应该根据生态承栽人数来制定;当公共景区基于社会福利最优定价时,完全免费并不一定是社会福利的最优选择.在此基础上,对多目标定价机制进行比较分析,并结合杭州西湖景区案例对多目标门票定价机制进行了动态综合研究.
