REGIONAL TIES AND DISCRIMINATION: POLITICAL CHANGE,ECONOMIC CRISIS,AND JOB DISPLACEMENTS IN SOUTH KOREA, 1997–99

Probing into the incidence of job displacements during the 1997–99 recession period, this study offers theoretically grounded micro‐causal explanations for regional ties and regional discrimination in South Korea. Our statistical analysis reveals the significant impact of a worker's birth region (the basis of regional ties and discrimination) on the layoff process. Native Kyongsang workers are found to have faced higher rates of layoff in Seoul‐Kyongki regional firms than native Jolla workers during the recession period. The Kyongsang–Jolla layoff rate gap is mainly due to differential treatment rather than a difference in observable characteristics. The findings suggest that the problem of regional ties and regional discrimination is more deep‐rooted and widespread in South Korea than previously reported.     

资本管制、外商投资与最优税差 --对中国转型时期过渡性资本外逃的研究

本文根据我国过渡性资本外逃的现实,构建一个政府和国内企业之间关于外资超国民待遇和资本投向的博弈模型,从理论上演绎了外资超国民待遇导致过渡性资本外逃的机制;揭示了资本管制程度对于过渡性资本外逃的效应;诠释了我国改革开放初期为何能够实施程度较高的内外资差别待遇,而在国内资本存量越来越大的今天,政府降低外资超国民待遇的客观必然性。文章进一步分析了当政府不了解企业资本外逃真实成本时,不对称信息对最优外资税率的效应。最后文章认为,统一内外资的税率和其他政策待遇是今后改革的必然取向

An industry test for ethnic discrimination in major league soccer

This paper tests for salary discrimination based on player ethnicity in Major League Soccer (MLS) by making innovative use of player movements in a unique setting. The discriminating team investigated is Club Deportivo Chivas USA, which had a preference for employing Hispanic players. Evidence of discrimination is found by analyzing how other teams valued the former players of Chivas USA differently across ethnicity after the team was disbanded by the league. The nature of MLS player contracts and drafting rules allow for a simple and unique test for salary discrimination that has not previously been possible to implement.     

Explicit expression of anti-black biases in the full-service restaurant industry: Legal responsibilities and risks

Anecdotes detailing racial prejudices and discriminatory treatment of Black Americans while dining in full-service restaurants surface routinely in the popular press. These anecdotes are buttressed by a small number of studies documenting evidence of racist language and observed mistreatment of Black restaurant customers. In an effort to further explore the pervasiveness and correlates of such explicit expression of anti-Black biases in restaurant workplaces, this study presents findings from an online survey that was administered in two independent, large, and demographically diverse samples of current restaurant employees. We find that on average between 15 % (Qualtrics sample) and 24 % (Facebook sample) of participants agreed with statements indicating that racist language and discrimination against Black customers is common in the restaurants where they work. We explore the individual and organizational correlates of such explicit expression of anti-Black biases in restaurant workplaces and highlight the associated legal ramifications. We conclude by encouraging restaurateurs to take action against manifestations of racial prejudice in their establishments in order to fulfill their legal responsibilities to both their customers and their employees and thereby to minimize the threat of litigation.     

Social norms,cooperation and inequality

This paper analyzes the outcomes that can be supported by social norms in a society of infinitely lived and patient agents that are randomly matched in pairs every period to play a given game. I find that any mutually beneficial outcome can be supported by a self-enforcing social norm under both perfect information and a simple local information system. These Folk Theorem results explain not only how social norms can provide incentives that support cooperation in a community, providing support to the concepts of social capital and corporate culture, but also how they can support inequality and discrimination.I am grateful to David Levine for invaluable guidance and ideas. I also thank Anna Aizer, Hongbin Cai, Walter Cont, Ernesto Dal Bó, Jean-Laurent Rosenthal, Federico Weinschelbaun, William Zame, anonymous referees and seminar participants at Universidad de Buenos Aires, UCLA, Universidad T.

Would You Like to be a Prosumer? Information Revelation,Personalization and Price Discrimination in Electronic Markets

Electronic commerce and flexible manufacturing allow personalization of initially standardized products at low cost. Will customers provide the information necessary for personalization? Assuming that a consumer can control the amount of information revealed, we analyze how her decision interacts with the pricing strategy of a monopolist who may abuse the information to obtain a larger share of total surplus. We consider two scenarios, one where consumers have different tastes but identical willingness to pay and another with high and low valuation customers. In both cases full revelation may only result if the monopolist can commit to a maximum price before consumers decide about disclosure.     

R&D investment under spatial price discrimination

This paper uniquely examines an R&D rivalry under spatial price discrimination and compares two alternative timings. When firms invest first, they locate efficiently but overinvest in cost‐reducing R&D if spillover is modest. When firms locate first, they locate inefficiently and always underinvest in cost‐reducing R&D. Although the R&D investment improves social welfare under either timing, profit always declines and so it would never be undertaken if firms cooperate. Both timings are relevant as we identify circumstances under which each will endogenously be chosen in a premarket stage. Critically, the equilibrium timing is often not the socially beneficial timing.     

金融时间序列指标判别框架：以特质波动率为例

基于拐点集合判别的TBUD方法主要思路是分析拐点集合间的关系,并在高维空间进行划分,从而搭建判别模型,并将分析框架应用在特质波动率等若干指标上,利用实证数据得到结论。应用 TBUD判别框架可以发现,特质波动率等指标无法对拐点集合进行清晰划分,因而并不具有预测能力。     

Subtle discrimination in the rental housing market: Evidence from e-mail correspondence with landlords

We find that landlords practice subtle discrimination in the rental housing market through the use of language associated with describing and viewing a unit, inviting further correspondence, making a formal greeting, and using polite language when replying to e-mail inquiries from a white name more often than to an African American name, they also send longer e-mails and respond quicker to white names.
