主讲人简介:
Lasio's research interests are Empirical Industrial Organization, Regulation and Competition Policy, Health Economics and the Economics of the Pharmaceutical Sector. She has published papers on top journals such as American Economic Review (AER) and International Journal of Industrial Organization. Most of her studies utilize structural estimation methods, and her AER paper analyzes the effects of regulating pharmaceutical price on demand and on manufacturers' price-setting behavior. Lasio obtained her doctoral degree in economics from Toulouse School of Economics in 2015.
摘要:
Lung cancer is associated with smoking and is characterized by low treatment rates and lower research funds with respect to other cancers. Research shows that patients with lung cancer often internalize societally biased beliefs on the effectiveness of treatment and the accompanying stigma, which may deter them from seeking treatment and, thus, hinder the diffusion of innovative therapies. We investigate the impact of social effects on treatment rates and innovation adoption using administrative data on advanced lung cancer patients in Ontario (Canada). We estimate a structural model of treatment choice where patients base their own decision on the treatment decisions of their reference group. Identification rests on the exogenous variation in the treatment propensity of physicians. We find that biased beliefs and stigma deter access to treatment: placing all patients in a neighborhood characterized by low social discrimination increases treatment rates by 4 percent and the use of innovative therapies by 3 percent. Social effects account for around 2 percent of the gap in research funding for lung cancer, which amounts to $7million every year in US public funding alone.

摘要:
The globalization of the world economy has been characterized by the liberalization of trade and the expansion of foreign direct investment, both of which would significantly impact the global environment. Multinational production (MP) is a key factor in this process, with the potential to generate both pollution haven and pollution halo effects, leading to opposing implications for the environmental impact of globalization. In this paper, we develop a quantitative multi-country multi-sector general equilibrium model with trade, MP and pollution that captures these forces in a rich geographic setting. After calibrating the model, we quantify the interaction of trade, MP and pollution, concluding that MP is crucial to understanding the environmental effects of globalization. Ignoring MP can seriously mislead the assessment of the environmental impact of trade liberalization. The pollution haven effect generally dominates the pollution halo effect, which results to a negative environmental effect of MP on host countries. We evaluate various forces that determines the MP pattern and its environmental effect, and conclude that environmental regulations provide a source of comparative advantage, but their influence on shaping the MP pattern is relatively weak. We also quantify the environmental effect of cross-country technique transfer through MP.

主讲人简介:
Xi Zhi “RC” Lim is an economist who specializes in microeconomic theory. He is currently Assistant Professor of Economics at Shanghai Jiao Tong University. He received a PhD in Economics from Columbia University in 2020. His research focuses on using an axiomatic approach to study how people make decisions. He is currently working on risk and time preferences, limited attention, and societal choice.
摘要:
I study how past choices affect future choices in the framework of attention. Limited consideration causes a failure of “rationality”, where better options are not chosen because the DM has failed to consider them. I innovate and consider sequences of choices, where past choices are necessarily considered in future choice problems. This provides a link between two kinds of rationality violations: those that occur in a cross-section of one-shot decisions and those that occur within a sequence of realized choices. In my setting, the former helps identify attention whereas the latter pins down true preferences. Both types of violations vanish over time and furnish a novel notion of stability. A series of results shows that attention across time can act as a manifestation of attention at a given time, and a full characterization of compatible models is provided.

深度学习、文本情绪与金融市场:兼论金融科技的逻辑

孟令超,8797威尼斯老品牌金融系博士生,研究方向为资产定价、行为金融、文本分析与机器学习。研究成果发表在《经济学季刊》上,有多篇论文在Journal of Business & Economic Statistics、《管理世界》等审稿,并在中国经济学年会、中国金融学年会等会议上宣读论文。同时担任Journal of Business & Economic Statistics、Management Science、《管理世界》等期刊匿名审稿人。
摘要:
深刻把握金融科技的应用逻辑,合理应用前沿深度学习模型,充分释放文本大数据要素,对于维护我国金融市场稳定发展具有重要意义。因此,本文基于金融文本大数据集和BERT深度学习模型,开展金融市场文本情绪测度和金融资产风险收益预测。研究发现,与传统的字典法文本情绪测度相比,使用BERT深度学习模型构建的情绪变量在金融市场预测上表现更佳。BERT情绪变量在不同经济阶段对宏观变量也存在显著预测能力,有效捕捉了非理性冲击对宏观基本面的影响。机制研究发现,BERT情绪在经济下行阶段与极端风险事件期间表现出了很强的预测效果,反映了BERT深度学习模型可以有效建模金融情绪与资产价格间的非对称、非线性关系。综上,本文对以BERT为代表的深度学习算法引入到金融情绪分析和金融稳定预警提供了理论和实证支撑,为金融科技推动金融业数字化转型迈入高质量发展新阶段提供了科学逻辑。

题目:清代常平仓粮食储额的制定与运行
摘要:
康熙年间,清政府将全国各州县划分三等,对应不同的常平仓应储粮食数量。在这种几乎整体划一的规定中,地区规模、人口数量成为决定储粮多少的重要标准,但忽略了其他因素的区域差异。这以后到雍正后期,随着清朝统治者对地域差异认识的深入,常平仓粮食储备的地域分异已渐具雏形。乾隆年间,清政府在各地常平仓积谷旧额的基础上,对各州县常平仓粮食储额做出了明确规定,并在之后有所调整。研究发现,清代常平仓粮食储额的分配考虑了人口、地理气候条件、受灾情况、军事等因素。乾隆末年至进入嘉庆时期以后,清政府的仓储系统日渐破坏,由于官吏寻租行为,常平仓制度反成为勒索百姓的工具。

题目:科举学子在近代海关的职业窘境——传统教育人才的“职业天花板”
摘要:
在外籍税务司背景下,早期近代海关华员在海关系统中主要担任中低级的职位,少部分华员在海关工作多年后获得晋升帮办这一高级职位的机会。在这些华员当中,少部分人具有一定的传统职衔,其中一些来自科举考试,一些来自捐纳,还有一些来自保举等方式。不同职衔背景的华员在海关系统中的任职存在明显差异,甚至有悖于传统观念上科举才是正途的观点,回归结果显示出单一科举职衔背景的华员反而在海关系统中担任更低级的文书工作,而非是具有一定地位的供事与帮办职位,其在海关系统中存在明显的“职业天花板”。这一研究揭示了社会经济发展水平与人力资本水平之间的关系。

题目:Household Division, Intergenerational Distribution of Wealth, and the Great Divergence (Research Proposal)
摘要:
The origins of the Great Divergence between China and Europe have long been at the center of economic history debates. Inheritance custom, as one of the informal institutions, is a relatively less explored angle. This study follows Chu (1991)’s model in which bequest division is an optimal decision to minimize lineal extinction probability under certain social mobility structures. The study aims to draw on household division records of the Que family to provide historical references for setting model parameters. We will compare the steady-state distribution of wealth under equal household division to its counterfactual under primogeniture. Moreover, we will show that a dissipated wealth distribution impedes capital accumulation and economic output in the long run, thus possibly providing evidence that household division might be one of the explanations for the Great Divergence.

摘要:
The RMB exchange rate policy follows a “two-pillar” rule, with the market pillar reflecting foreign exchange market conditions and the basket pillar stabilizing the RMB index. This documents a clear pattern of regime-switching in the policy coecients on the market pillar. We further find that macroeconomic variables, the intraday market condition as well as the news on trade conflict drive the regime-switching of policy coecients. In a Markov- switching rational expectations model, we demonstrate that regime-switching rules expand the set of policy combinations to guarantee the economy’s determinacy and to rule out self- fulfilling depreciation. A policy implication is that the regime change of the RMB policy rule, driven by different economic conditions, is a generalization of the counter-cyclical factor — a policy tool that the PBOC uses to stabilize the RMB exchange market.

摘要:
在房价上涨和房地产市场繁荣的背景下,中国出现居民消费萎缩、经济增长日益依赖基建投资、实体经济投资被大量挤出的现象。对此,本文建立了一个多部门DSGE模型,在一个统一的框架下对这一系列现象复制并进行了解释。研究发现,尽管房价上涨带动了总投资和GDP,但金融摩擦和土地财政带来了更多中国特色的结构性问题:居民融资约束导致家庭杠杆随着房价一同攀升,并抑制了消费,使得中国经济主要靠总投资拉动;房价地价的上升通过土地财政和基建投资带动了总投资的上升;更多的资金流向房地产部门,加之金融中介的摩擦,使企业面临更高的融资成本;同时中国土地市场的分割导致工业用地不能随住宅用地升值,隔断了制造业企业的抵押融资效应,最终导致实体经济投资被挤出。
