Estimation of tail‐related risk measures in the Indian stock market: An extreme value approach

The purpose of the study is to estimate tail-related risk measures using extreme value theory (EVT) in the Indian stock market. The study employs a two stage approach of conditional EVT originally proposed by McNeil and Frey (2000) to estimate dynamic Value at Risk (VaR) and expected shortfall (ES). The dynamic risk measures have been estimated for different percentiles for negative and positive returns. The estimates of risk measures computed under different quantile levels exhibit strong stability across a range of the selected thresholds, implying the accuracy and reliability of the estimated quantile based risk measures.     

Learning to Argue with Intermediate Macro Theory: A Semester-Long Team Writing Project

The authors describe their experience with integrating a semester-long economic analysis project into an intermediate macroeconomic theory course. Students work in teams of “economic advisors” to write a series of nested reports that analyze the current state of the economy, and propose and evaluate policies for a decision-maker. The project simulates real-world policy consulting with an emphasis on applying economic theory and models. The authors describe the project setup and how to tailor its theme to current events, explain methods for keeping it manageable in larger classes, discuss student learning outcomes, and document course evaluation results. Besides improving the learning experience, this project prepares economics students to contribute their own views to policy debates and buttress them with tight macroeconomic reasoning.     

Gender,family ties,and international mobility: Cultural distance matters

This study empirically tests a model of associations between family-domain variables and willingness to accept an international assignment, and applies the general model to sub-samples of men and women to examine gender differences in the pattern of relationships. We further explore these patterns in culturally similar and culturally distant country destinations. Analyses conducted with a sample of 148 men and 79 women employed MBA graduates from dual-earner couples revealed that perceived spouse willingness to relocate, beliefs regarding spouse and couple mobility, relative income, and the presence of children are associated with willingness to accept an international assignment. Moreover, consistent with social role theory, significant gender differences in willingness were found across low and high cultural distance country destinations.     

A theory of collusion with partial mutual understanding

Unlawful collusion is when firms have a mutual understanding to coordinate their behavior for the purpose of achieving a supracompetitive outcome. Given the legal focus on mutual beliefs, this paper explores the role of mutual beliefs in producing collusion. Focusing on price leadership, firms are assumed to commonly believe that price increases will be at least matched but lack any shared understanding about who will lead, when they will, and at what prices. Sufficient conditions are derived which ensure that supracompetitive prices emerge. However, price is bounded below the maximal equilibrium price.     

Pure joint production and international trade: a note

This paper applies the principles of the neo-Ricardian (or Sraffian)theory of international trade to certain joint production systems.It is shown that, in contrast with single-product systems, (i)there is not always a pattern of international specialisation,which would entail the increase of the real wage rate in botheconomies, and (ii) the ‘law of comparative advantage’has no general validity. Furthermore, not only the existenceof such a pattern of specialisation but also the validity ofthis law depend on the values of the variables of distributionof income. The analysis is wholly based on two of the numericalexamples formulated by Bidard in 1997, and further generalisedin an elementary way only when this is considered necessary.     

CEO特征与国际化战略——来自中国制造业上市公司的证据

在中国较为特殊的公司治理和管理环境中,CEO对企业战略决策具有重大影响。同时,由于中国权力距离较大,与国外相比CEO在企业中发挥的作用可能更为重要。基于高层梯队理论,本文探讨CEO年龄、教育程度和任期对国际化战略的影响。有别于基于发达国家的研究结论,实证研究表明：（1）CEO教育程度与国际化程度显著负相关,教育程度高的CEO倾向于规避国际化战略带来的高风险。（2）CEO年龄与国际化程度呈正U型关系。CEO年龄越小越有动机从事国际化经营,另一方面,CEO年龄越大经营管理经验和社会资本越丰富,这两方面的共同作用使CEO年龄与国际化程度呈正U型关系。（3）CEO任期与企业国际化程度显著正相关。CEO任期越长越有利于打造和谐、高效的高管团队,从而提升上市公司的国际化程度。     

The Exchange Rate and Inflation in Argentina: A Classical Critique of Orthodox and Heterodox Policy Prescriptions

In this paper we present an alternative framework to neoclassical theory of international trade and exchange rate determination. Our model, inspired in the classical tradition, provides support for the assertion that an exchange rate policy aiming to improve national competitiveness and to bring about a sustained trade surplus is a viable option. In fact, the success of this strategy does not depend on the effectiveness of monetary sterilization —as many argentinean heterodox authors claim— but on the ability to overcome the boundaries imposed by the evolution of the domestic wage rate and the potential emergence of competitive devaluations. In the particular case of Argentina, the introduction of export taxes on land-intensive commodities, in which the economy has absolute advantages, brings an additional policy tool that can make both the exchange rate target and the workers claims consistent.     

多关系条件下多代理人行为分析与激励机制设计

针对多个代理人之间存在多种关系———竞争、合作和中立的情况,建立了信息对称和信息非对称条件下的多代理人行为选择模型,通过模型求解与模拟计算分析多关系条件下多代理人的行为选择和委托人的最优选择或激励机制。结果表明:信息对称条件下,员工薪酬与员工间的竞争程度无关,但合作关系更能激励员工努力工作;信息非对称条件下,员工间关系影响其薪酬和企业利润,合作关系下的企业总收益比其他关系下的企业收益高,员工间的合作关系会影响并提高处于其他关系下员工的努力程度。最后提出:企业面对多员工管理问题时应尽量构建合作的工作环境,以减小员工工作努力程度的不确定性、实现利益最大化。     

刍议证券市场中的投资者保护理论

资者保护是全球证券市场发展过程中的一个十分重要问题,一直为各国官员和学者所关注,作为一个近二十年历史的新兴市场,中国目前在投资者保护方面还存在一些突出的问题,主要从投资者保护的概念,探讨投资者保护的两个理论：契约论和法律论,以及投资者保护的意义,借此为如何维护中国证券市场的持续、健康发展,保护中小投资者利益提供参考。
