Pharmaceutical cost‐sharing systems and savings for healthcare systems from parallel trade

This paper studies the consequences of parallel trade in a two‐country model. It compares a coinsurance scheme (consumers pay a percentage of the drug price) and an indemnity insurance scheme (reimbursement is independent of the drug price) with respect to changes in copayments and public health expenditure. In the destination country, copayments for patients decrease to a larger extent under indemnity insurance, whereas reductions in public health expenditure occur only under coinsurance. In the source country, copayments increase less under coinsurance, whereas health expenditure is reduced more under indemnity insurance. In both countries, total expenditure under parallel trade is lower.

The effectiveness of fear appeals in ‘green’ advertising: An analysis of creative,consumer, and source variables*

This study focused on the effectiveness of fear appeal messages used to arouse a threat in green advertising. An experiment recruited 175 participants to test the influence of the advertising appeal (fear vs. non-fear appeal), source (for-profit vs. non-profit organizations), and involvement with the environment on attitude toward the ad (A_ad), attitude toward the product (A_p) and purchase intention (PI). Results revealed that a fear appeal in a green ad negatively affected A_ad and A_p and that participants who were highly involved with the environment were more likely to have positive attitudes toward the green ad and advertised green product as well as a stronger intent to purchase it. The source type in the green ad did not affect ad effectiveness and involvement with the environment did not moderate the effects of either appeal or source.     

基于Metlab的多机器人围捕问题的研究

本文将追捕-逃跑问题按空间、时间离散化后转为一个对策模型,并利用Matlab软件,采用栅格建模的方法来模拟仿真环境,对四个追捕机器人追捕一个目标机器人的实例进行了仿真。通过仿真发现了该支付函数的缺陷。基于此原因,重新定义了局中人的支付函数,通过衰减因子μ,在追捕的不同阶段,根据追捕的具体情况灵活地调整距离影响系数和有效包围系数的权重,从而提高了追捕的效率。
