Surface street traffic volume and single-family house price

This study investigates the relationship between surface street traffic volume and single-family house prices in a relatively small city in the US. Hedonic price models are estimated using data from 9670 transactions that occurred between January 1998 and March 2011. It is discovered that parcels fronting or adjacent to a high-traffic street sell, on average, at an 8.1% discount compared to similar parcels that are not so situated. Restricting the analysis to parcels on or adjacent to a high-traffic street, house price and traffic volume are found to be negatively related; a doubling of volume from any particular traffic count, ceteris paribus, reduces selling price by an average of 2.1%.

综合考虑托运人面对集卡运输服务和货运代理报价两大顾客选择因素,构建由多个竞争性集卡运营商和一个货运代理商组成的集装箱道路运输市场竞争模型,通过逆向归纳法求解博弈均衡并以上海港进行算例分析.研究发现:若集卡运营商采取提供增值服务策略,则一方面由于承担了增值服务所需成本而导致集卡运营商利润下降;另一方面,集装箱道路运输市场需求的满足程度不断提高,集卡运营商和货运代理商的整体利润也呈现增加趋势.因此,通过对集装箱运输链建立合理的利益分配机制,就能激励集卡运营商主动提供增值服务,从而改变当前集装箱道路运输市场在基本运输服务方面进行恶性价格竞争的局面,实现集卡运营商和集装箱运输链的健康发展.     

考虑动态定价的煤炭调运方案优化研究

煤炭坑口价格的变化与市场供求有重要联系.本文在煤炭坑口价格动态定价的基础上,以煤炭产地和消费地间的煤炭调运量为决策变量,以煤炭流通过程中的总费用最小化为目标,分别构建了煤炭调运系统优化模型和考虑消费者竞争的煤炭调运优化模型,设计了遗传算法和Floyd算法相结合的求解算法.以我国内地煤炭调运问题为案例,分析了价格变化特性、可调出量与消费量比例等因素对煤炭调运方案的影响.结果表明,考虑消费者竞争时煤炭流通广义费用更低;随着煤炭可调出量与消费量比的增加,动态价格较固定价格的煤炭流通广义费用下降更快.

Direction dependent prices in public transport: A good idea? The back haul pricing problem for a monopolistic public transport firm

Markets for transport are often characterised by unequal demand in both directions: every morning during peak hours the trains are crowded while moving towards the direction of large cities, whereas they may be almost empty in the other direction. In this paper we discuss the implications of these imbalances for price setting of transport firms. From the viewpoint of economic theory, two regimes can be distinguished: one where – owing to price discrimination – the flows are equal, and one where unequal flows are the result. Special attention is paid to the case where the transport firm does not apply price discrimination, as is the case with most railway firms in Europe. We find that in the case of substantial joint costs, the introduction of price discrimination not only leads to an increase of profits, but also to positive effects on consumer surplus. This result differs from the standard result in the literature on industrial economics. The standard result purports that with linear demand functions price discrimination has a negative impact on the welfare of the average consumer and that this negative impact dominates the positive effect on profits of the producer.
