氣候變化威脅地球食水供應、減少農業生產、危及沿海地區、損害人類健康，並使生態系統惡化。極端天氣造成的過度死亡，更被認為是一大災難性後果。據2017年發表於《科學》（Science）期刊的一篇文章估計，到二十一世紀末，極端氣候帶來的超額死亡成本可能佔美國氣候災難損失總額約70%之多。

新冠疫情肆虐，一波未平一波又起，在大灣區，深圳封城抗疫初見成效，廣州又開始爆發新一輪疫情，面對相對嚴格的抗疫政策，當地居民是如何適應？

Police complicity in organized crime is not uncommon, yet it is extremely difficult to examine empirically. Using unique sex transaction data from China, we show that police can be complicit in organized prostitution. Specifically, we document that sauna houses and massage parlors with greater neighborhood police density are likely to be “protected” by police and thus can host higher-risk, higher-penalty sex business. The complicity effect is particularly salient during periods of local prostitution crackdowns, implying selective enforcement. Changes in local leadership and visits of the central government’s discipline teams can attenuate the complicity effect.

面對新冠大流行，不同國家採取了不同應對措施。港大經管學院今日（30日）表示，由港大經管學院經濟學、管理及商業策略學副教授何國俊博士領導的國際研究小組，近日量化了內地嚴格的抗疫政策對非新冠死亡率的影響，研究已於權威科學雜誌《自然-人類行為》發表。

“Environmental economics has become a hot topic recently, so I am very honoured to be entrusted by the Faculty’s management to be a pioneer in this field. Through education, I hope I can also open a new research area for aspiring young scholars to join the academia.”

Dr. Guojun He is an economist specialised in environmental economics and development economics. Grasping the opportunity to spearhead the line of research related to environmental and economic policies in HKU, Dr. He had officially joined us in July 2021 as an Associate Professor in Economics.
