Speaker: Julius Schönherr is an assistant professor at Peking University. He graduated from the University of Maryland in 2019 with a thesis on social coordination and the problem of other minds. His research, which has been published in journals such as Philosophical Studies, Synthese and the British Journal of the Philosophy of Science, spans a wide range of topics in social epistemology, the philosophy of mind and moral philosophy. His current focus is on issues concerning epistemic injustice. Here, he outlines the scope and dimensions of harm one can experience in one's capacity as a knower.Venue: Room 311, Building 4, Chengjun Yuan, Zijingang CampusAbstract: Many speech acts have morally significant, communicative side-effects, i.e., they give uptake to morally problematic propositions that are neither part of the literal or implicated meaning of the speaker’s utterance, nor are they presupposed by the speaker. I call these communicative side-effects messages. For instance, experimental evidence suggests that talk of “inner city crime” tends to give uptake to morally problematic inferences about black crime that may be wholly unintended by the speaker. While the evaluative properties involved in messages have been thoroughly recognized and, more importantly, analyzed, a similar analysis of these messages’ deontic properties – i.e., the conditions under which it is (im)permissible for a speaker to send them – has yet to be forthcoming. In this talk, I will provide this analysis. I shall appeal to the famous doctrine of double effect, which I will modify to accommodate the fact that it is sometimes permissible to send a harmful message if audience uptake is sufficiently irrational.

Speaker: Prof. WANG Tianyu, School of Economicsand Management, Tsinghua UniversityChair: Prof. YU Yifan, School of Economics, Zhejiang UniversityVenue: 426, Buiding of School of Economics, Zijingang Campus, Zhejiang UniversityTime: 14:00-15:30 on May 26, 2023Abstract: We study the information content of over-the-counter foreign exchange (FX) option volume using a granular dataset with counterparty identities and contract characteristics. We find that FX option volume negatively predicts future exchange rate returns, especially when the concentration of informed investors increases, during periouds of high dollar demand, and with options offering higher leverage opportunities. Our findings support an asymmetric information model, where informed traders choose whether to trade in the option market to exploit their information advantage. We also document that hedge funds and real money investors display superior skills at predicting future exchange rates compared to less sophisticated players.

Speaker: Dr. FANG Limin (University of British Columbia)Venue: Zijingang CampusAbstract: We investigate the impact that uniform "one-size-fits-all" tax policies have on shaping the retail landscape. An entry model demonstrates that tax effects on retailer entry can amplify market concentration. Using data about retail establishments in the United States, we show that while they are more likely to open in markets with favorable state tax policies, these markets become more concentrated as entry is dominated by the largest chains. Therefore, tax policies might impact the retail industry competitiveness, despite the policies' uniform design.

Speaker: Prof. XUE Sen, Institute for Economic and Social Research, Jinan UniversityHost: Dr. SHI Xinjie, School of Public Affairs, Zhejiang UniversityVenue: Conference Room 729, Building A, Creative Building, Zijingang CampusAbstract: This paper examines the effect of a safe housing program that has greatly improved housing conditions for the poor in a most impoverished ethnic minority region in China, where almost half of the labour force had no formal schooling in 2010. We find that the safe housing program significantly increases labour income (i.e., the sum of agricultural income, business income and wage income) for the poor, and the effect is stronger among the higher-educated and those in villages with better conditions and amenities. We provide supporting evidence that this positive income effect is due to the health improvement and increase in investment for the future caused by the safe housing program. Consistent with the push-pull theory of migration, as the safe housing program weakens the push factor, we also find that it reduces migration and wage income.

Speaker: Dr. Micheal SpenceDr. Michael Spence took up his post as President & Provost of UCL on 11 January 2021. Prior to this he was Vice-Chancellor and Principal of the University of Sydney (2008-2020), which under his leadership rose to first in Australia and fourth in the world for graduate employability. He was also responsible for the largest philanthropic campaign in Australian history, raising a record one billion Australian dollars. Dr. Spence is recognised internationally as a leader in the field of intellectual property theory and holds a Doctor of Philosophy in Law from the University of Oxford, where he headed Oxford’s Law faculty and Social Sciences division. He has university qualifications in English, Italian, Law, Theology and Korean, and learned Chinese while in Oxford. In 2017, he was awarded a Companion of the Order of Australia in the Australia Day Honours for service to leadership of the tertiary education sector, to the advancement of equitable access to educational opportunities, to developing programs focused on multidisciplinary research, and to the Anglican Church of Australia. Dr. Spence is an ordained Minister in the Anglican Church.Venue: Qiushi Lecture Hall, Zijingang Campus Abstract: Last year, researchers in the UK and China co-published over 19,000 research papers. Behind that extraordinary number is an extraordinary story, one of finding common purpose across cultures and domains. If the exchange of knowledge, thought and practice across divides has become an integral part of the academic life of the modern university, then how do universities equip our students with these ‘interface’ competencies?

Speaker: Lyu Chen (Peking University HSBC Business School)Venue: Room 718, School of Economics Zhejiang University, Zijingang CampusAbstract: A recommendation platform sequentially collects information on a new product revealed from past consumer trials and uses it to better guide later consumers. Because consumers do not internalize the value of information they bring to others, their incentive for trying out the product can be socially insufficient. Given such a challenge, study howthe platform can maximize the total surplus generated on it by designing its recommendation policy. In a model with binary product quality and general trial-generated signals. I show that the optimal design features a sequence of time-specific thresholds, which vary in a U-shaped pattern over the product's life. At any time, the platform should recommend the product if based on its current belief the probability of the product's quality being high is above the current threshold. This characterization allows me to provide predictions about the recommendation dynamic and study comparative statics regarding the optima recommendation standards. My analysis also illustrates the potential usefulness of a Lagrangian duality approach for dynamic information design.
