We conducted a nationwide field experiment in China to evaluate the direct and indirect impacts of assigning firms to public or private citizen appeals when they violate pollution standards. There are three main findings. First, public appeals to the regulator through social media substantially reduce violations and pollution emissions, while private appeals cause more modest environmental improvements. Second, public appeals appear to tilt regulators' focus away from facilitating economic growth and toward avoiding pollution-induced public unrest. Third, pollution reductions by treated firms are not offset by control firms, based on randomly varying the proportion of treated firms at the prefecture level.

國際知名學術期刊《科學》近期以封面論文形式刊發了題為《綠色助推減少即棄餐具：來自中國外賣行業的證據》的研究，主要探討綠色助推如何有效增加「不需餐具」訂單的份額。該研究的第一及通訊作者、港大經管學院經濟學及管理與商業策略副教授何國俊表示，是次研究利用在中國收集的數據，發現綠色助推可以顯著減少外賣產生的塑料廢物。

漢朝宗室大臣兼文學家劉向在《說苑．臣術》篇中將人臣分為十二種類型，六為正，六為邪，其中「諛」便是「六邪」之一。篇中將其描述為「主所言皆曰善，主所為皆曰可，隱而求主之所好而進之，以快主之耳目，偷合茍容，與主為樂，不顧其後害，如此者，諛臣也」，意指那些認為君主說的話都是好的、君主的行為都是對的，只會投其所好、阿諛奉承，助長君主的逸樂而不顧嚴重後果的馬屁精。

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.
