Unemployment dynamics in an OLG economy with public pensions

Pension benefits in old age establish a disincentive to save in youth, thereby yielding lower levels of capital stock and the wage rate. As a result, the trade union has an incentive to change the composition of its two targets: employment and the wage rate. This paper develops a model that includes employment effects of public pensions via capital accumulation and union wage setting. Within this framework, we consider how contribution rates to the pension system influence the level and time path of the unemployment rate. It is demonstrated that (1) a higher contribution rate results in a lower unemployment rate, and (2) the economy with a high (low) contribution rate experiences monotone convergence towards (oscillatory convergence towards or a period-2 cycle around) the steady state.

Market Structure and Risk Taking in the Banking Industry

We demonstrate that the common view according to which an increase in competition leads banks to increased risk taking fails to hold in an environment where homogeneous loss averse consumers can choose in which bank to make a deposit based on their knowledge of the riskiness incorporated in the banks outstanding loan portfolios. With an exclusive focus on imperfect competition we find that banks incentives for risk taking are invariant to a change in the banking market structure from duopoly to monopoly. Finally, we show that deposit insurance would eliminate the gains from bank competition when banks use asset quality as a strategic instrument.revised version received October 15, 2003     

当前我国农业保险发展的主要问题及对策建议

我国农业保险正面临着极好的发展机遇,出现了良好的发展势头.但目前仍然存在制约我国农业保险发展的诸多因素,主要是:农业风险本身的可保性差;农业保险经营技术落后;农民收入低,政府投入少;法律法规建设缺位等.我国农业保险要健康有序的发展,必须改进农业保险经营技术;建立有效的再保险机制;增加政府投入,逐步实行以支持农业保险为主的农业保护政策;加快农业保险立法进程,使农业保险走上规范化制度化发展的轨道.     

我国保险业市场结构特征及对策分析

本文依据传统的产业组织理论,从市场集中度、产品差别化、进退障碍三个方面分析中国保险业的市场结构特征,得出我国保险业是一个寡头垄断行业,并进一步提出解决这种寡头垄断市场结构的对策措施.     

关于农业保险立法的建议

构建多层次农村金融体系是新农村建设的难点，农业保险在分散和降低农业金融体系系统性风险方面发挥着无可替代的作用。我国应针对现行农业保险法律法规存在缺失的状况，坚持正确的立法原则，逐步完善农业保险立法，促进新农村建设顺利推进。     

《旅行社投保旅行社责任保险规定》的弊端及完善

通过分析《旅行社投保旅行社责任保险规定》施行近5年来出现的保险范围不合理,保险金额低,保险费率混乱,责任难认定,理赔程序有弊端及未规定说明义务等问题,提出了统一制订保险范围条款,提高保险金额,规范保险费率,设立仲裁委员会,改革理赔程序及引入说明义务条款等措施,试图为完善旅行社责任保险法规提供借鉴。     

保证保险合同的性质及其法律适用

保证保险是保险人作为保证人为义务人即投保人向权利人提供担保。对保证保险合同性质的不同界定，进而带来不同的法律适用。虽然在立法上在加快且有效地对保证保险行为进行规范，但在现行法律框架没有相应的行为关系模式下，本着法的基本精神，在现行法律框架以外谋求解决问题的合理途径，无疑是现实的和亟需的。

乡村振兴战略背景下农业保险发展对策研究——以四川省为例

乡村振兴战略的有效实施离不开金融体系的有力支持,农业保险作为金融支农重要工具在乡村振兴战略实施过程中发挥着重要作用。本文以四川省农业保险发展为研究案例,结合全国农业保险发展概况,点面结合深入分析了农业保险服务乡村振兴的内在逻辑、现状与问题,从乡村振兴依靠主体--老人农业与新型农业经营主体对风险的异质性需求角度出发,论述了农险服务乡村振兴的主要任务。本文认为,现阶段农业保险服务乡村振兴还存在顶层设计不合理、供需错配、目标定位不清导致中长期规划滞后、创新激励不足等结构性问题。基于此,本文提出从中央、省级政府以及保险公司三方出发,采取农险供给侧改革、优化顶层设计、加强农险宣传,提升农户保险意识、探索互助农险合作模式、充分运用互联网高新技术提高风险管控能力等政策建议。
