摘要：
What determines the use of labor coercion? This paper studies the impact of trade on an important form of coercion in colonial Indonesia: the payment of taxation in the form of labor, a practice known as corvée labor. To do so, I construct the first database on corvée labor usage and exports covering sixteen Indonesian residencies over forty-one years (1900-1940). I find trade expansions, especially of labor-intensive exports, reduced corvée usage. This effect runs through laborers buying themselves out of corvée duties. The buy-out option enabled high-productivity laborers to self-select out of corvée without requiring stronger information-collection capabilities of the state. Through increased buyouts, the fall in in-kind taxation was mirrored by a rise in monetary taxation. The opposite took place during the trade collapse of the Great Depression. While some studies find a positive relationship between trade and private labor coercion, I argue public labor coercion follows a different logic due to the state's encompassing interest. The nature of the relationship between coercer and coerced is thus key in understanding labor coercion.

主讲人简介：
Martin Eling is Dean of the School of Finance, Director of the Institute of Insurance Economics and Professor for Insurance Management at the University of St. Gallen. He is doing empirical research in the intersection of insurance business, economics, and mathematics. His research interests include a broad range of topics in strategic management, financial management, risk management, and asset management. The current agenda includes new research topics such as cyber risk and micro insurance. His research has been awarded by several leading institutions including the American Risk and Insurance Association (ARIA), the Casualty Actuarial Society (CAS), and the National Association of Insurance Commissioners (NAIC). Among other activities, he is also board member of Concordia, one of Switzerland’s largest health insurance companies.
摘要：
This talk highlights major trends and challenges the European insurance industry faces with respect to the next seven years. Among these are the interest rate environment, the changing customer behavior, and the role of insurance in a digital world. The session is interactive: The relevance of the trends and the position of the Chinese companies with respect to the trends is analyzed in a live survey among participants and compared with Swiss companies.

摘要：
In a variety of applications, including nonparametric instrumental variable (NPIV) analysis, proximal causal inference under unmeasured confounding, and missing-not-at-random data with shadow variables, we are interested in inference on a continuous linear functional (e.g., average causal effects) of nuisance function (e.g., NPIV regression) defined by conditional moment restrictions. These nuisance functions are generally weakly identified, in that the conditional moment restrictions can be severely ill-posed as well as admit multiple solutions. This is sometimes resolved by imposing strong conditions that imply the function can be estimated at rates that make inference on the functional possible. In this paper, we study a novel condition for the functional to be strongly identified even when the nuisance function is not; that is, the functional is amenable to asymptotically-normal estimation at root n rates. The condition implies the existence of debiasing nuisance functions, and we propose penalized minimax estimators for both the primary and debiasing nuisance functions. The proposed nuisance estimators can accommodate flexible function classes, and importantly they can converge to fixed limits determined by the penalization regardless of the identifiability of the nuisances. We use the penalized nuisance estimators to form a debiased estimator for the functional of interest and prove its asymptotic normality under generic high-level conditions, which provide for asymptotically valid confidence intervals. We also illustrate our method in a novel partially linear proximal causal inference problem and a partially linear instrumental variable regression problem.

摘要：
An emerging argument is that since humans can readily adapt to changing climatic conditions, there is less need to pursue aggressive emissions mitigation strategies. As temperature adaptation is a function of repeated exposure over time, we need empirical approaches that can faithfully depict individuals’ temperature history to rigorously examine this claim. Using a longitudinal dataset representative of China, we construct lifetime temperature exposure unique to each individual based on their birth-dates, birth-locations, and movement history. We show that a 1°C increase in individualized temperature anomalies cause a 2% decrease in 1 S.D. of well-being, where most of the impacts are driven by “hotter-than-expected” weather. In turn, we show that while the adverse impacts of future temperature changes wane after accommodating for adaptation, acclimatization is unlikely to keep pace with future temperature increases except in the net-zero emissions scenario, indicating that stringent GHG emissions cuts are still needed even in this less-pessimistic scenario.

The Effects of Frequent Disclosure on Price Informativeness and Cost of Capital in a Keynesian Beauty Contest Setting
主讲人：魏旭（中央财经大学金融学院教授）
主持老师：高明（北京大学经济学院长聘副教授）
时间：2023年11月10日（周五）12:30-14:00

摘要：
We study the effects of more frequent public disclosure in a two-period rational expectations equilibrium model with short-term investors, thus featuring Keynesian beauty contest. We find that including public disclosure in every period generates substantially different results on how disclosure affects price informativeness and cost of capital, compared with the previous literature in the absence of public disclosure after trading. Specifically, the introduction of future-period public information can both increase price informativeness of the previous period through alleviating the beauty contest effect and decrease price informativeness through crowding out the informativeness of future disclosure. We find that more frequent disclosure unambiguously increases informativeness of all prices, in contrast to the independence result documented in the previous literature. In addition, more frequent disclosure has a more subtle effect on ex-ante cost of capital, again in contrast to the independence result documented previously. Our results provide novel empirical and regulatory implications.
