金融租赁公司的利率风险及管理对策

金融租赁公司所面临的诸多利率风险中,成熟期错配风险是最为关键的,久期模型是其通用的衡量方法。金融租赁公司的久期缺口分析是利用久期管理利率风险的主要方法,但久期模型运用中也存在着诸如久期对称成本高、利率风险免疫动态性及凸性等问题。金融租赁公司面对利率上升的风险,应采取设立风险管理部门、做好基础资料积累与分析、加强利率走势预测及对金融衍生工具的研究等对策措施。     

Matching and anonymity

This work introduces a set-theoretic foundation of deterministic bilateral matching processes and studies their properties. In particular, it formalizes a link between matching and informational constraints by developing a notion of anonymity that is based on the agents’ matching histories. It also explains why and how various matching processes generate different degrees of “informational isolation” in the economy. We illustrate the usefulness of our approach to modeling matching frameworks by discussing the classical turnpike model of Townsend.This research is supported in part by the NSF grants EIA-0075506, SES-0128039, DMS-0437210, and ACI-0325846.

企业研究与开发绩效评价:现状分析及改进思路

由于研发活动固有的特点,企业研究与开发(以下也称研发或R&D)的绩效评价一直是理论和实践上的难题。通过分析影响企业研发绩效评价因素,探讨现行的企业绩效评价体系存在的问题,得出了可以利用平衡计分卡设计企业研发绩效评价指标体系的结论。     

基于平衡计分卡的项目管理绩效评价模型研究

传统的项目管理往往仅将其管理领域局限于项目与项目实施间的行为,缺乏与组织战略相互因应的结合。以项目为导向(Project-base)的组织中,通过员工之间的互相支持,资源共同分享的方式,使企业能够快速地应变不同的需求与变动,动态的调整项目的分配,从而强化企业的竞争优势。本文的研究目标是试图采用平衡计分卡的模式作为项目管理与组织战略结合的桥梁,摆脱传统上单纯以量化模式评估绩效的方式,而从多个层面针对项目管理的绩效作一个较为全面的探讨,期望能使项目管理的绩效与组织战略更加紧密结合。通过平衡计分卡四个层面的绩效评价,充分地分析组织整体与项目个别的绩效表现,提供管理人员快速发现问题与制定决策的依据。     

财产保险公司资产负债管理多维量化评估体系研究

良好的资产负债管理是保险业可持续发展的基石,也是支持保险业在日益复杂的风险环境中保持稳健发展、防范系统性风险的重要保障。近年来,随着我国金融市场发展,业务产品创新加快,保险业在资产端与负债端的业务结构和风险特征出现了新情况、新变化。特别是部分保险公司缺乏有效的治理结构,采取激进经营、激进投资的策略,导致业务快进快出、风险敞口过大以及流动性问题,对保险公司资产负债匹配管理、风险控制提出了挑战。本文介绍了财产保险公司资产负债多维度量化评估规则设计原理、主要评估模型和评估方法,针对财产保险公司的负债特性提出的沉淀资金匹配,在成本收益匹配中有机地将资产投资收益与承保业务综合成本进行匹配,在现金流匹配模式中打破了僵化的匹配模式,解决了长期困扰财产保险公司的资产负债期限不匹配的问题,对财产保险公司资产负债管理具有重要意义。     

Revenue Sharing versus Expenditure Sharing in a Federal System

Problems of intergovernmental policy coordination can take many forms and are becoming increasingly important with continuing economic integration. In this paper we focus on the fiscal competition problem where the non-cooperative choice of taxes and transfers among governments typically leads to a suboptimal outcome. We look at the effect of two widely used corrective policies: revenue sharing and expenditure sharing (or intergovernmental matching grants). Our main result is that these two corrective policies have opposite effects depending on the form of competition between governments, namely whether governments compete in taxes or expenditures. More precisely, for any form of competition, revenue sharing is desirable exactly when expenditure sharing is not and vice versa. The implication is that the choice of the optimal corrective policy requires a complete understanding of the underlying non-cooperative behavior among governments. Our second main result is that neither revenue sharing or expenditure sharing can be sustained as a Nash equilibrium among governments, although all governments would benefit from one of these two corrective policies. Central intervention is therefore inevitable unless governments can pre-commit to the optimal corrective policy before setting their fiscal policies.     

新环保法实施增大了企业的技术创新投入吗？——基于PSM-DID方法的研究

以2012—2017年A股上市公司为样本,借助双重差分倾向得分匹配法（PSM-DID）研究了新环保法实施这一外生性事件对企业技术创新投入的影响。结果显示,新环保法实施后受影响企业的技术创新投入有所增加,但结果并不显著。进一步探究其原因,发现除新环保法影响可能存在的时滞性特征以外,企业并没有在新环保法实施环境下对企业的资本结构、治理结构和激励方案等影响企业技术创新的重大方面做出及时调整,导致环保法的强制性作用无法快速、有效地影响企业的技术创新。     

Money,random matching and endogenous growth: A quantitative analysis

In this study, we develop a search-and-matching monetary growth model to analyze the effects of inflation on economic growth and social welfare by introducing endogenous economic growth via capital externality into a two-sector search-and-matching model. We find that the channel through which inflation affects economic growth in the search-and-matching model is different from the traditional cash-in-advance model. To facilitate the calibration, we obtain an empirical estimate of the effects of inflation on economic growth using panel regressions. In the simulation analysis, we quantitatively evaluate the welfare effect of inflation in the search-and-matching endogenous growth model and compare it to a search-and-matching exogenous growth model. We find that the welfare effect of inflation is nonlinear in the endogenous growth model whereas it is linear in the exogenous growth model. Furthermore, we find that the welfare cost of inflation under endogenous growth is up to four times as large as the welfare cost of inflation under exogenous growth.

The substitutes condition and the lattice structure of the set of stable allocations

In the many-to-one matching model with contracts, I show that there is no restriction on preferences weaker than substitutable preferences which guarantees that the set of stable allocations is a lattice. Thus, when contracts are not substitutes, removing agents from the economy may decrease the payoffs to existing agents on both sides of the market.
