Following the Fukushima nuclear accident, Japan gradually shut down all its nuclear power plants, causing a countrywide power shortage. In response the government launched large-scale energy-saving campaigns to reduce electricity consumption. Exploiting the electricity-saving targets across regions and over time, we show that the campaigns significantly increased mortality, particularly during extremely hot days. The impact is primarily driven by people using less air conditioning, as encouraged by the government. Nonpecuniary incentives can explain most of the reduction in electricity consumption. Our findings suggest there exists a trade-off between climate change mitigation and climate change adaptation.

Subjective performance evaluation could induce influence activities:employees might devote too much effort to pleasing their evaluator, relative to working toward the goals of the organization itself. We conduct a randomized field experiment among Chinese local civil servants to study the existence and implications of influence activities. We find that civil servants do engage in evaluator-specific influence to affect evaluation outcomes, partly in the form of reallocating work efforts toward job tasks that are more important and observable to the evaluator. Importantly, we show that introducing uncertainty about the evaluator’s identity discourages evaluator-specific influence activities and improves bureaucratic work performance.

气候变化威胁地球食水供应、减少农业生产、危及沿海地区、损害人类健康，并使生态系统恶化。极端天气造成的过度死亡，更被认为是一大灾难性后果。据2017年发表于《科学》（Science）期刊的一篇文章估计，到二十一世纪末，极端气候带来的超额死亡成本可能占美国气候灾难损失总额约70%之多。

新冠疫情肆虐，一波未平一波又起，在大湾区，深圳封城抗疫初见成效，广州又开始爆发新一轮疫情，面对相对严格的抗疫政策，当地居民是如何适应？

警方包庇有组织犯罪的情况偶有所闻，但往往很难通过实证来研究。研究利用来自中国独特的性交易数据，证实地方警察或对一些有组织的卖淫活动提供庇护。具体而言，位于警力密度较高的社区内的桑拿浴室和按摩院，受到警方「保护」的机会较高，进而可以进行高风险、高罪责的卖淫活动。在地方警察「扫黄」期间，这种庇护效应更加明显，意味着选择性执法的存在。地方领导层的变化和中央政府纪律部队巡视则会显著减弱这种庇护效应。

面对新冠大流行，不同国家采取了不同应对措施。港大经管学院今日（30日）表示，由港大经管学院经济学、管理及商业策略学副教授何国俊博士领导的国际研究小组，近日量化了内地严格的抗疫政策对非新冠死亡率的影响，研究已於权威科学杂誌《自然-人类行为》发表。
