Optimal transit fare and service frequency of a nonlinear origin-destination based fare structure

This paper proposes a new nonlinear distance-based transit fare structure, which is measured by a function of the Euclidean distance between the origin and destination stations, termed as Origin-Destination (OD)-based fare. The novel fare structure encourages passengers to freely choose the most efficient trip plan. An optimization model is formulated based on a three-party game (involving the transport authority, transit company, and passenger) to determine the optimal fare function and frequency. An artificial bee colony algorithm is adopted to solve the model. Finally, a numerical example is provided to verify the proposed method.

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.     

The importance of being earners: why women in South Africa need well-paid jobs

The ‘children fare better’ viewpoint claims that children tend to be better fed if their mother (as opposed to father) has sufficient income of her own for food. This paper assesses this claim for South Africa, using data from household surveys. It considers the possibility that this issue is related to domestic violence between husband and wife, and finds an apparent link between wife's earnings, child nutrition and domestic violence. Children's well-being seems more assured if mothers have an adequate income; but there is more risk of inadequate nutrition in households where there is domestic violence against wives.     

The impact of low-cost carriers on airport choice in the US: A case study of the Washington–Baltimore region

Previous research has shown that low-cost carriers (LCCs) may stimulate traffic at an airport by offering low fares. Using passenger survey data from the Washington–Baltimore region’s three airports, we find that the benefits of LCCs to airports extend beyond the traffic generated directly by the LCCs through their low fares. In addition, we find that the mere presence of an LCC at an airport can attract passengers, even to competing carriers. These “halo effects” from LCC presence increase the significance to airport managers of attracting LCCs in order to generate passenger demand.

从消费者心理谈食品通路策略

任何企业要想发展壮大,产品的生产必须能满足消费者的某种需求,产品的销售必须能迎合消费者的消费心理,只有这样,企业才能拥有众多的消费者,成功地占领市场。通路是指促使产品或服务顺利地被使用或消费的一整套相互依存的组织。食品的通路策略解决的是商品流的问题,目的是排除影响消费者购买的风险心理,将产品以最短的时间、最少的费用、最合理的途径从生产者手中转移到消费者手中,以提高产品的竞争力。     

景区门票涨价的经济影响路径分析——平遥古城案例研究

门票涨价是社会引发争论的热点之一。2009年,旅游景区门票涨价问题在社会上再次激起强烈反应。面对门票涨价,有学者总结门票涨价对旅游发展的瓶颈问题,但究竟导致了怎样的经济影响还缺乏实证研究。本研究以世界文化遗产平遥古城为例,对门票涨价做了实证研究。
