摘要：
This paper applies the framework from Arkolakis (2010) to study Chinese firms’ behavior on market penetration. In this framework other than prices, firms endogenously choose how much efforts they spend on market penetration. The model predicts that as a country’s output tariff reduces, more firms start exporting and previous exporters export more. These unintuitive predictions are directly driven by the drop in wages in labor market as domestic firms’ outputs reduce in the competition with imports. All firms adjust their marketing efforts, measured the trademarks that they hold domestically and overseas. We take Chinese firms’ overseas trademarks to establish the effect that market penetration takes in channeling import competition to exports. Making use of China’s accession to the WTO in 2001, we provide clear empirical evidence for the model. Chinese firms in sectors with larger import tariff reductions apply for more foreign trademarks, i.e., higher efforts in market penetration.

摘要：
Over the last decade, watching videos online has become one of the primary uses of the internet, with streaming services accounting for more than 60% of global internet traffic. In this paper, we use a novel data set on Netflix, the largest streaming platform worldwide, to estimate the patterns of catalogue availability (extensive margin) and the number of clicks per title (intensive margin) across twenty countries. This data set also gives us a unique opportunity to estimate the importance of quality in viewing patterns. Our results show evidence of the gravity framework explaining both margins of Netflix watching. In addition, we find that there is a strong preference for domestic content, better-rated titles, and Netflix Original productions. These findings suggest that as Netflix produces more content, this will interact with its streaming dominance to provide a significant advantage in reaching viewers and promoting specific content.

主讲人简介：
Michael R. Powers is the Zurich Insurance Group Chair Professor at Tsinghua University’s School of Economics and Management. He also holds a dual appointment as professor of economics and business at Tsinghua’s Schwarzman College. From 2012 to 2015, he served as chair of Tsinghua’s finance department.
In 2013, Powers won the Kulp-Wright Book Award for Acts of God and Man: Ruminations on Risk and Insurance, in which he proposes a new “science of risk”. He is co-editor of three academic books – The Political Economy of Chinese Finance; Global Risk Management: Financial, Operational, and Insurance Strategies; and The Economics and Politics of Choice No-Fault Insurance – and author of the science-fiction novel, Icons.
Professor Powers joined Tsinghua from Temple University’s Fox School of Business, where he was professor of risk management and insurance. Prior to that, he served as deputy insurance commissioner for the Commonwealth of Pennsylvania, and was responsible for designing Pennsylvania’s current “choice” no-fault automobile insurance system.
Powers provides regular commentary for CGTN’s Global Watch and Global Business programs and China Radio International’s Biz Today and World Today shows, and is frequently interviewed by major international media organizations.
摘要：
We offer two novel characterizations of the Zeta distribution for insurance claim frequencies: first, as tractable continuous mixtures of Negative Binomial distributions (with fixed shape parameter, r > 0), and second, as a tractable continuous mixture of Poisson distributions. In both the Negative Binomial case for r ∈ [1, ∞) and the Poisson case, the resulting Zeta distributions are identifiable because each mixture can be associated with a unique mixing distribution. In the Negative Binomial case for r ∈ (0,1), the mixing distributions are quasi-distributions (for which the quasi-probability density function assumes some negative values).

摘要：
We develop a model in which consumers search experts to obtain recommendations and prices to treat a problem, while experts may “cheat” by recommending an unnecessary treatment. We characterize the optimal sequential search strategy by consumers with a positive search cost, and show that consumer search and expert behavior interact in rich and---at times---surprising ways. In equilibrium, all experts behave honestly if search cost is sufficiently low, but cheating occurs with positive probabilities otherwise. In the latter case, an increase in search cost can actually reduce expert cheating, yielding a higher search benefit that restores optimal consumer search under the higher search cost and also leads to lower prices.

摘要：
This paper studies the interaction of search and application approval in credit markets. We build a model that combines search and screening in presence of asymmetric information. Risky borrowers internalize the probability that their application is rejected, and behave as if they had high search costs. Thus “overpayment” may be a poor proxy for consumer sophistication since it partly represents rational search in response to rejections. Contrary to standard search models, our model implies 1) endogenous adverse selection through the search and application approval process, 2) a possibly non-monotone or non-decreasing relationship between search and realized interest, default, and application approval rates and 3) search costs are not identified from transaction prices alone. Using a unique dataset detailing search behavior of mortgage borrowers, we find support for the model's predictions: borrowers who search a lot pay higher interest rates than those who search a little. Estimating the model, we find that screening is informative and search is costly. Counterfactual analyses reveal that tightening lending standards and discrimination through application rejection both increase equilibrium interest rates. Overall, we establish a tight link between application rejection and realized interest rates in equilibrium.
