Is Representation Enough? Racial Disparities in Levels of Force and Arrests by Police

The research in representative bureaucracy that examines the extent to which racial congruence impacts bureaucrats’ decisions is mixed. This study adds to this literature by examining the impact of representative bureaucracy on the level of force that police officers use and whether they make an arrest in use of force encounters, while taking into consideration key situational conditions. Using individual-level data from New Orleans to estimate this impact, the authors find that racial congruence and incongruence impact policing outcomes even in the presence of situational shortcuts that cue decision-making. The findings show that the benefits of representation are conditional on the outcome. Black officers are less likely to use higher levels of force on Black civilians. Yet both Black and White officers are less likely to arrest White civilians in use of force encounters. This suggests that interactions in which bureaucrats have less discretion (e.g., arrests) may offer limited opportunities for active representation.     

Does Medicare Coverage Improve Cancer Detection and Mortality Outcomes?

Medicare is a large government health insurance program in the United States that covers about 60 million people. This paper analyzes the effects of Medicare insurance on health for a group of people in urgent need of medical care: people with cancer. We used a regression discontinuity design to assess impacts of near-universal Medicare insurance at age 65 on cancer detection and outcomes, using population-based cancer registries and vital statistics data. Our analysis focused on the three tumor sites for which screening is recommended both before and after age 65: breast, colorectal, and lung cancer. At age 65, cancer detection increased by 72 per 100,000 population among women and 33 per 100,000 population among men; cancer mortality also decreased by nine per 100,000 population for women but did not significantly change for men. In a placebo check, we found no comparable changes at age 65 in Canada. This study provides the first evidence to our knowledge that near-universal access to Medicare at age 65 is associated with improvements in population-level cancer mortality.     

理解中美关系的裂痕

中美关系是当下亚太地区正在发生的政治和战略变化的决定性因素,中美之间的竞争并不奇怪,它是国际关系的一种形式,关键是中美的利益冲突是对抗性的还是非对抗性的。这一问题在中美两国的官员、思想者、媒体中都引发了激烈的争论。部分美国高级官员认为中国的一些行为是修正主义的,但其实它们是保护主义的。从东亚总体来看,东北亚存在修正主义国家,东南亚则没有。因此,南海发生重大危机的可能性不大,而东北亚将给东亚带来很大的不确定性。     

THE CRITICAL CLIMATE AGENDA

The world set a goal in the Paris Agreement: to keep global warming within 1.5 degrees Celsius of preindustrial levels. The Intergovernmental Panel on Climate Change has explained why this is a valid goal. If global warming were to go higher than 1.5 degrees Celsius, this would jeopardize life on the planet with a potential multi-meter sea-level rise, the collapse of critical ecosystems, and the release of methane from thawing permafrost, possibly triggering runaway warming. Yet the world's current trajectory implies a catastrophic 2.7-degree- Celsius increase in global temperature.     

应税事实依据经济实质认定之稽征规则——基于台湾地区“税捐稽征法”第12条之1的研究

台湾地区税捐稽征法第12条之1课税构成要件之认定及明订举证之责任,将税捐稽征中已实行多年的实质课税原则条文化。当避税安排的法律形式与其经济实质不相符时,稽征机关认定应税事实应以实质经济事实关系及其所生实质经济利益之归属与享有为依据。由量能课税原则导出的实质课税原则,重经济实质甚于法律形式,是实现税捐正义的实质性手段,并不违背税收法定原则。稽征机关实质课税的自由裁量权理应谦抑行使,其以税捐负担的公平分配为原则,以不损害纳税人的合法权益为底限。稽征机关依据经济实质认定应税事实,应依法承担举证责任,纳税人依法应尽协力义务,否则,稽征机关有权推定应税事实。大陆《税收征管法》亦应增订实质课税原则。     

香港与内地仲裁裁决司法审查制度的借鉴和融合

通过对香港和内地在仲裁裁决司法审查范围、标准和技术方面的综合分析,本文认为两地在司法制度、法治发展和仲裁理念上的较大差异导致了两地在对待仲裁裁决司法审查上之截然不同。重要的是,香港法院对仲裁的支持态度及其具体审查操作的先进经验,可为内地在这一领域的改革提供重要指引。《香港与内地关于相互执行仲裁裁决的安排》实施近十年来,已逐渐出现两地仲裁界和司法界在审查制度面向上的趋同。惠于"一国两制"和"更密切经贸关系"的大背景,相信两地间商事仲裁的融合会更加蓬勃发展,为中国跨境商事活动提供更好的争端解决服务。
