When is upstream collusion profitable?

Motivated by the recent antitrust cases in which Japanese auto parts suppliers colluded to raise supply prices against their long‐term collaborators, the Japanese carmakers, we study the conditions under which an upstream collusion is profitable even after compensating downstream direct purchasers. Oligopoly competition in successive industries is shown to give rise to a vertical externality and a horizontal externality. If a collusive price of intermediate goods better balances the two externalities, the collusion will raise the joint profit of all firms in the two industries and is therefore profitable for the upstream after compensation of downstream firms.     

探讨影响干体式温度校验器校准结果的因素

通过对干体式温度校验器校准过程中垂直方向标准温度计的位置、标准器直径与测温孔的选配和记录间隔对其温度偏差及温度波动度进行比较试验,结果表明标准温度计与测温孔直径要尺寸相当并插入至均温块底部;记录间隔可适当缩短并结合实时测量曲线进行温度波动度校准,可提高校准结果的准确性.     

灵活就业人员医疗保险参与及受益归属——基于逆向选择和正向分配效应的双重检验

当前,灵活就业人员医疗保险发展不充分与不平衡的问题格外突出,这不仅会制约医保制度公平性与可持续能力的提高,同时会阻碍经济社会的全面、协调和可持续发展。本文运用中国劳动力动态调查数据(CLDS),研究灵活就业人员参加医保的决定因素以及受益归属,从而为新时期医保制度顶层设计提供决策依据。结果表明:一方面,无论是在参保决策还是险种决策阶段,灵活就业人员的健康风险显著正向影响参保状态,说明逆向选择效应显著存在;另一方面,低收入的参保人利用了更多优质的医疗服务,获得了更多的医保基金补偿,并显著改善了健康状况,因此医保发挥了积极的正向分配作用。但是过高的保障水平,在改善医疗可及性的同时会激发道德风险,从而加剧逆向选择问题并阻碍正向分配效应,对更加公平可持续医保制度的建立造成负面影响。     

基于固定翼飞机前视近红外图像的实时跑道检测

为实时、精确地提取固定翼飞机前视图像中的跑道区域，提出了一种惯性辅助的近红外图像跑道检测算法。首先利用惯性导航信息和跑道角点的大地坐标，生成虚拟跑道轮廓，并估计跑道感兴趣区域(Region of Interest,ROI)；然后对ROI区域进行细节增强，从中提取直线段；在虚拟跑道轮廓的辅助下拟合跑道边缘线，提取跑道特征。经真实数据验证，所提法可以从机载前视红外图像中实时、精确地检测出跑道特征，在33 frame/s的帧率下检测准确率达97%。     

Why is contemporary China still courting concubines? Exploring the reasons for Chinese audiences’ fascination with concubines’ infighting in television dramas

ABSTRACT

This note reports the results of a systematic exploration and evaluation of the reasons underlying the very high popularity among Chinese audiences of a particular television genre featuring infighting between concubines in ancient imperial courts. Self-report questionnaires were completed by 263 respondents to assess the value they perceived to earn from watching this type of drama. Factor analysis identified five categories of experiential value yielded from watching this genre, covering dimensions related to its exquisite visual and audio effects, intriguing plots, and aroused contemplations. Linear regression showed that experiential value positively predicted audience satisfaction with this type of drama and audience satisfaction affected their choice to make it a future leisure activity, despite the potential ban of this genre by the Chinese authorities. The findings suggest that Chinese audiences’ infatuation with dramas featuring concubine infighting expresses a dichotomy of both reflection and inflection of the realities of contemporary social and cultural dynamics, thereby articulating the unique functions of leisure in facilitating this social process.

Income inequality,corruption and subjective well-being

ABSTRACT

Based on the data of CGSS2013, we analyse the relationship between income inequality, corruption and subjective well being using an Ordered Probit model. Our results indicate that income inequality and corruption significantly reduces the subjective well-being of our country’s residents. Furthermore, corruption is an important channel for the negative effect of income inequality on subjective well-being, the impact of income inequality on subjective well-being is mainly achieved by the role of corruption. Specifically, the impacts vary according to hukou. Higher degree of income inequality indeed reduces the subjective well-being of urban residents, while it has a positive effect on subjective well-being of rural residents. Corruption has a significant negative impact on the subjective well-being of urban and rural residents. There is heterogeneity in the influence of different income levels in rural areas. The study in this paper shows that anti-corruption and narrowing the income gap are the two major grippers to improve the well-being of the residents.
