Some characterizations of distributions of the exponential-type

We consider a particular subclass of the two-parameter exponential family with natural parameters γ₁, γ₂ and characterize those distributions of the family having a ratio of the mean value and the variance that is a linear function of γ₁ by the form of the moment generating function. As special cases we find the normal and the gamma distributions.     

基于进化博弈的专利联盟形成研究

专利联盟作为高新技术产业发展的主导范式,对技术标准的建立有重要的作用。但是多数情况下提高社会福利的联盟却难以形成,这就是所谓专利联盟的形成困境问题。从专利权人的有限理性和重复博弈角度分析专利联盟的形成,分别建立对称和非对称专利联盟形成的进化博弈模型,得到不同条件下的进化稳定策略,并探讨影响联盟形成的条件和因素。研究结果表明,专利联盟更容易在弹性高、竞争激烈的市场环境中形成;与事实标准建立以后相比,在事前组建的专利联盟形成可能性更大;通过多方途径保护和提高加入联盟的专利权人的利润,同时抑制阻碍联盟的专利权人的利润,是促进联盟形成的关键;与专业R&D企业相比,纵向一体化企业有更强的动机加入联盟。健全和完善相关法规及配套服务对联盟形成也是有益的。

Mexican American Fathers' Occupational Conditions: Links to Family Members' Psychological Adjustment

To examine the implications of fathers' occupational conditions (i.e., income, work hours, shift work, pressure, workplace racism, and underemployment) for family members' psychological adjustment, home interviews were conducted with fathers, mothers, and two adolescent offspring in each of 218 Mexican American families. Results underscored the importance of acculturation as a moderator. Fathers' income was negatively associated with depressive symptoms in highly acculturated families but not in less acculturated families. In contrast, fathers' reports of workplace racism were positively associated with depressive symptoms in less acculturated families but not in more acculturated family contexts. These findings were consistent across all 4 family members, suggesting that the "long arm" of the jobs held by Mexican American fathers extends to mothers and adolescent offspring.     

家庭策略与农村非常规核心家庭夫妻权力关系的变化

文章从社会互构论的视角,对社会转型时期国家与家庭互构背景下农村非常规核心家庭内部夫妻权力关系的变化进行了探讨。随着“外出打工”家庭策略的制定,夫妻双方的权力分配适应了外出打工的策略安排,适应了双方的性别分工模式,体现了家庭整体利益至上的原则。     

供应链中信用交易的演化博弈分析

本文运用演化博弈理论研究了供应链中信用交易的演化过程,建立了供应商和零售商信用交易的演化博弈模型。分析了两类个体在守信与失信两种策略下的行为特征,根据复制者动态方程得到了两者的行为演化规律和政府失信惩罚机制下的行为演化和演化稳定策略,给出了从根本上消灭失信动机的惩罚区间,分析了政府失信惩罚机制的有效性,探寻国内信用制度建设的发展路径。最后,通过数值分析证明了结论的正确性。     

基于博弈模型的“公司+农户”模式契约稳定性及模式优化

为探索解决"公司+农户"模式违约问题的优化模式和对策,通过静态博弈模型揭示了"公司+农户"模式违约问题的根本原因是市场风险的存在,并得出了稳定的"公司+农户"模式的价格波动区间;契约稳定性模型揭示了"利益共享"的分配机制、"公司+农户"经营模式交易费用的降低、约束机制的加强和信誉机制的建立都有利于"公司+农户"经营模式的稳定和发展。引入期货、期货期权对"公司+农户"模式进行优化,通过博弈模型分析得出:"公司+农户+期货"优化模式能解决公司的违约问题,但没能解决农户的机会主义行为和违约问题;"公司+农户+期货期权"优化模式从根本上扼制了农户的违约行为,规避了公司远期合约的市场风险,稳定了公司未来的得益和农产品货源,也解决了公司的风险和违约问题。     

Gambling Reputation: Repeated Bargaining With Outside Options

We study the role of incomplete information and outside options in determining bargaining postures and surplus division in repeated bargaining between a long‐run player and a sequence of short‐run players. The outside option is not only a disagreement point, but reveals information privately held by the long‐run player. In equilibrium, the uninformed short‐run players' offers do not always respond to changes in reputation and the informed long‐run player's payoffs are discontinuous. The long‐run player invokes inefficient random outside options repeatedly to build reputation to a level where the subsequent short‐run players succumb to his extraction of a larger payoff, but he also runs the risk of losing reputation and relinquishing bargaining power. We investigate equilibrium properties when the discount factor goes to 1 and when the informativeness of outside options diffuses. In both cases, bargaining outcomes become more inefficient and the limit reputation‐building probabilities are interior.     

Strategic Liquidity Provision in Limit Order Markets

We characterize and prove the existence of Nash equilibrium in a limit order market with a finite number of risk‐neutral liquidity providers. We show that if there is sufficient adverse selection, then pointwise optimization (maximizing in p for each q) in a certain nonlinear pricing game produces a Nash equilibrium in the limit order market. The need for a sufficient degree of adverse selection does not vanish as the number of liquidity providers increases. Our formulation of the nonlinear pricing game encompasses various specifications of informed and liquidity trading, including the case in which nature chooses whether the market‐order trader is informed or a liquidity trader. We solve for an equilibrium analytically in various examples and also present examples in which the first‐order condition for pointwise optimization does not define an equilibrium, because the amount of adverse selection is insufficient.
