PARTISAN ADVOCATES

This paper studies the problem of an uninformed decision maker who acquires expert advice prior to making a decision. I show that it is less costly to hire partisan agents than impartial agents, especially under advocacy, and that the decision maker prefers partisan advocacy to other forms of institutions. I also extend the literature, originating with Dewatripont and Tirole ( 1999 ), to a setting with contracts that condition on information provided and not just the decision made.     

防恶意干扰的VANET双群联合定位算法

传统的无线定位方法直接应用于车辆自组织网络(VANET)时，会被窃听方利用定位信息，从而导致严重的安全隐患。为此，提出基于Bancroft方法的双群组合定位算法,用于保障车辆自组织网络中车辆定位的安全性和准确性。算法利用两个群组的智能车辆节点分别进行定位，利用两组解分别反求伪距值，如果所获得的伪距值与经过节点钟差修正后的原始伪距值基本一致，则认为这一组解为最终的定位结果，从而保证了定位的正确性。同时，双群定位的信息分散性保证了系统整体的安全性。理论分析及算法仿真表明,双群联合定位算法可使窃听方的误码率稳定在较高水平。     

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.     

Wealth effects and agency costs

We analyze how the agent's initial wealth affects the principal's expected profits in the standard principal–agent model with moral hazard.We show that if the principal prefers a poorer agent for all specifications of action sets, probability distributions, and disutility of effort, then the agent's utility of income must exhibit a coefficient of absolute prudence less than three times the coefficient of absolute risk aversion for all levels of income, thus strengthening the sufficiency result of Thiele and Wambach (1999). Also, we prove that there is no condition on the agent's utility of income alone that will make the principal prefer richer agents. Moreover, we show that, for an interesting class of problems, the principal prefers a relatively poorer agent if agent's wealth is sufficiently large. Finally, we discuss how alternative ways of modeling the agent's outside option affects the principal's preferences for agent's wealth.

旅游产业发展与居民消费结构——基于1994～2009年经验数据

旅游产业的发展和居民消费结构有重要的关联,研究居民消费结构的变化对旅游产业的发展具有十分重要的意义。通过对1994～2009年旅游消费和居民消费结构有关数据的分析,发现我国旅游消费的增长速度在不断放缓,导致旅游产业的发展可能面临瓶颈。城乡二元结构对旅游消费有重要影响,城镇居民旅游消费降低与住房、医疗和教育等支出有关,农村居民旅游消费可能会发展为新的增长点。
