A Game-Theoretic Model Of The CouP D'État

I explore the comparative vulnerability of regimes to a coup d'état using a game-theoretic model. Analysis centers on leaders of groups capable of intervening at the time of a coup. I prove the existence of an equilibrium in which a coup is attempted without restrictions on current government policy, the breadth of participation in politics, or the relative size of the conspiracy. Comparative statics results concerning the willingness of plotters to stage a coup and other leaders to join a coup once under way are established. Differences in comparative regime vulnerability stem from differences in the amount of organization required to attempt a coup.

经济效率的决定框架:技术、资本与闲暇——兼对日本和丹麦的实证检验

传统的经济增长理论在考察增长时主要关注其规模与速度,本文认为随着对经济发展质量的日益重视,经济效率问题同样需要关注.本文注意到,传统增长模型主要涉及工作时间内的生产,但闲暇时间不但对工作时间形成替代,其中的活动还对个体素质及其工作效率有互补作用.为此,本文将闲暇时间引入内生增长模型,并用"时人均GDP"来衡量经济效率,建立经济效率模型,模型显示:受教育时间和闲暇时间是影响经济效率的重要因素,但这种作用是非线性的.随后,通过引用跨国数据对模型进行检验,结果表明:经济效率的最主要决定因素是技术因素,其次是受教育时间,闲暇时间最初对经济效率有负作用,但随着经济发展水平的提高,闲暇时间的增加有利于经济效率的提高.     

Job Security,Financial Security and Worker Well‐being: New Evidence on the Effects of Flexible Employment

This paper uses panel data drawn from the Household, Income and Labour Dynamics in Australia (HILDA) survey to provide new evidence of the links between unemployment, wages, job security, financial security and workers' well‐being for workers in flexible employment. Our findings indicate that workers in flexible employment encounter more unemployment and experience increased job insecurity; unemployment is associated with wage penalties. Lower wages, job insecurity and financial insecurity affect well‐being. However, these negative outcomes are mitigated by longer job tenure. Our results have implications for moves towards a flexicurity model of employment     

双重二元转型与结构调整:模型、命题与中国的经验结果

通过结构调整实现经济增长方式的转型是新时期中国经济实现可持续增长的关键。按照科学发展观的思想,转型成功的核心在于科学地认识我国经济结构演进的机制,而这必须基于对我国经济环境约束条件的清晰认识,以及以此为前提的科学逻辑分析。据此,文章从中国城乡和地区的经济双重二元性现实出发,通过构造一个跨部门和地区的一般均衡模型,对中国结构调整的市场实现机制进行了全面考察。文章认为,中国的结构调整可以通过城乡和地区在要素与产品等方面的结构性互动实现,而其具体的实现机制是地区与城乡非均衡所带来的套利机会,政府的作用在于在尊重这种规律的基础上,着力于解决市场失灵问题。     

Current Accounts and Exchange Rates: A New Look at the Evidence

A small literature has developed exploring nonlinearities in exchange rate data. This paper studies bivariate statistical relationships between current accounts, exchange rates, and cross–country ratios of GDP. The analysis differs from previous empirical work on these issues in using nonparametric methods to allow for nonlinearities, in employing a minimum of statistical assumptions, and in focusing on a fundamental characterization of the data. The authors present new evidence on the connections between exchange rates, the current account, and GDP. While the evidence loosely supports some common beliefs about the data, it conflicts with some common theoretical models. Thus the results pose new challenges for theory.

Health insurance and consumption: Evidence from China’s New Cooperative Medical Scheme

We exploit a quasi-natural experiment arising from the introduction of a health insurance program in rural China to examine how the insurance coverage affects household consumption. Results show that, on average, the health insurance coverage increases nonmedical-related consumption by more than 5%. This insurance effect is observed even in households with no out-of-pocket medical spending. In addition, the insurance effect is stronger in households with worse self-reported health status. These results are consistent with the precautionary savings argument. The insurance effect also varies by household experience with the program. In particular, the effect is significant only in villages where some households have actually obtained reimbursement from the insurance program. The program within these villages stimulates less consumption among new participants than among households that have participated in the program for more than a year.     

沪深港股市动态联动性研究——基于三元VAR-GJR-GARCH-DCC的新证据

随着经济全球化的迅速发展,国际资本市场呈现出一体化趋势,各地证券价格的联动性也日趋显著。本文梳理已有理论文献,并总结经验成果的不足,在此基础上,构建三元VAR-GJR-GARCH-DCC整合分析框架,对沪深港股市联动效应进行了严谨而全面的实证检验。研究结果表明:沪深港三个市场具有联动效应,直接或间接引导对方;沪深股市对港市的新息冲击做出类似的反应,并且它们与港市的动态关联性具有趋同性,该结论为沪深两市合并提供了新证据;三个市场的相关性具有时变的动态特征,"中国因素"与"世界因素"的相关性正趋于增强。上述实证结论对投资者重新认识市场运行机制,合理制定投资策略以及监管当局有效防范国内外股市风险,推进股市整合均具有重要的启示意义。     

出口贸易、教育投入与经济增长:理论模型与经验证据

笔者借鉴获得性技能模型思想,研究教育投入通过影响外贸发展间接影响经济增长的路径,并重点考察两者对经济增长的联合影响机制.利用2004年～2009年31个省市数据进行实证分析,结果表明:教育投入对经济增长的边际影响为负且教育行业投入与出口贸易对经济增长的联合影响正向显著.可见教育投入对经济增长的直接促进作用,远远小于其通过促进外贸发展间接促进经济增长的作用.     

资产的理性定价模型和非理性定价模型的比较研究--基于中国股市的实证分析

本文以 1 995年 2月— 2 0 0 2年 6月深沪两市A股上市公司为样本 ,考察和对比三个定价模型———CAPM、三因素模型和特征模型。实证研究发现 :(1 )中国股市存在显著的“账面市值比效应”(BMEffect)和“规模效应”(SIZEEffect) ,但对于小公司则不存在“1月份效应” ;(2 )三因素模型比CAPM能更好地描述股票横截面收益的变化 ;(3 )基于“股票横截面收益是由公司特征决定”的非理性定价理论的特征模型不成立 ,而基于“股票横截面收益是由风险因素决定”的理性定价理论的三因素模型成立。这些发现说明 ,账面市值比和公司规模这二个变量代表的是一种“风险因素” ,并非“特征因素” ,因此中国股票横截面收益的变化取决于风险因素 ,而非特征因素。作者认为 ,导致上述结果的主要原因是中国股市长期的同涨同跌特征。     

Parallel Imports in a Model of Vertical Distribution: Theory, Evidence and Policy

Parallel imports are goods traded without the authorization of an original trademark or copyright owner. In this paper, a model where parallel imports arise because of incentive problems in vertical distributions is discussed. A distributor receiving goods from a manufacturer at a low wholesale price can profitably sell the goods in another country, outside the authorized distribution channel. The manufacturer can limit such parallel imports by raising wholesale prices, but this reduces vertical pricing efficiency. Parallel imports can thus occur in equilibrium. The model is supported by empirical evidence from existing studies and new econometric work. Policy implications of the analysis are discussed.     

利率模型的新发展--市场模型

利率模型一直是金融领域的热点。一种新的利率模型——市场模型，其建模原则是由模型得到的标准金融衍生品的定价必须和Black计算的价格相符。笔者认为，市场模型有操作简单方便的优点，这是传统利率模型不具备的，它虽然也有一定缺陷，但仍不失为一种方便使用者的较理想方法。     

Price Limits, Information Acquisition, and Bid–ask Spreads: Theory and Evidence

A number of futures markets use price limits which, in effect, preclude trade from occurring at prices outside certain exogenous bounds. Noting that such markets are characterized by heterogeneously informed traders, whereas previous work on price limits assumes symmetrically informed traders, we examine the effects of price limits in a setting where market participants are asymmetrically informed. We find that imposing price limits generally lowers the quality of information acquired in equilibrium, but lowers bid–ask spreads as well. Thus, depending on the relative weights placed by society on liquidity versus price efficiency, there may exist a set of price limits that are most efficient in achieving a trade-off between liquidity and informational efficiency. We perform empirical tests of some implications of the model using cross-sectional data on price limits. We find that price limits are strongly negatively related to both price volatility and trading volume. Though other explanations for our empirical findings cannot be ruled out, these results are not inconsistent with the model's implication that price limits should be tighter for contracts which offer greater profit potential for informed traders.     

市民收入不均与城市住宅价格空间分布——理论模型与数值模拟

文章通过对市民收入分布特征和市民购房能力与意愿的假设,将市民收入和住宅价格结合起来,从理论上探讨了市民收入不均对城市住宅价格空间分布的影响,并进行了数值模拟。分析表明,商业聚集导致城市从中心到外围房价呈逐渐下降的外在空间规律,是由市民收入差异及其购房竞价这个"内因"实现的。收入不均程度的变化会引起城市不同区位的房价变化,市民总收入一定时,基尼系数增大会导致城市中心房价上升和边缘房价下跌;高基尼系数下出现多次购房的可能较大,这将抬高相关区位的房价。     

企业化经营：区域性环境治理新模式

随着我国经济发展,环境污染已成为一个很大的社会问题,污染不仅大幅抵消了经济增长带来的社会福利,还严重阻碍了我国的可持续发展。目前,我国在环境治理的手段上,主要是政府的行政计划,市场化程度十分落后,在现实治理中常常是政府干预失灵,治理绩效不甚理想。为适应社会主义市场经济的快速发展,我国的环境治理应逐渐引入市场机制,针对不同类型的环境资源,寻求新的治理途径。一、区域性环境资源的产权特性产权问题是经济学对环境污染原因的一个共识性解释：大多数环境资源是公共物品,其产权不安全或根本不存在,容易产生外部效应…     

New Evidence on Intra‐Household Allocation of Resources in Japanese Households

This paper examines intra‐household allocation of resources to gain insight into family relationships and gender bias in Japanese households. We take the Engel curve approach to examine how adult consumption is affected by the presence of a child, either a boy or a girl, in the family. Empowered by diary‐based high quality spending data from the Family Income and Expenditure Survey, our empirical results show that adult consumption is significantly reduced in households with children; furthermore, gender bias is not observed in total adult expenditures, while responses of adult clothing expenses to the presence of a child are significantly different between a boy and a girl: spending on a father's clothing is reduced when the child is a school‐aged daughter, while spending on a mother's clothing decreases when a school‐aged son is in the home. Our analysis also shows that after the early 2000s girls receive a larger share of spending for children's clothing as well as for high school education than boys.
