牲畜保险、需求与参与率研究——基于浙江省生猪养殖户微观数据的实证研究

牲畜保险是农业保险的重要组成部分,生猪保险作为大宗农产品的风险保障近年来受到政府高度重视。农业保险参与率问题是农业保险的基本问题,生猪保险参与率的研究相对较少。本文利用一手资料对生猪保险的需求进行研究,使用Logistic模型,采用农户疫苗花费等代理变量对生猪保险参与率问题进行了实证研究,并对农户退保行为进行分析。研究发现:影响农户生猪保险参与率的因素主要有农户的风险规避程度、对生猪保险认知程度、养猪规模等变量。降低生猪保险理赔环节和交易成本,提高农户对农业保险的认识可以在一定程度上提高生猪保险参与率。

Investigating the performance of different estimation techniques for crop yield data analysis in crop insurance applications

We investigate the performance of the ordinary least squares (OLS)‐, M‐, MM‐, and the Theil–Sen (TS)‐estimator for crop yield data analysis in crop insurance applications using Monte Carlo simulations. More specifically, the performance is assessed with respect to trend estimation, prediction of future yield levels, and the estimation of expected indemnity payments. In agreement with earlier findings, other estimators are found to be superior to OLS in simple regression problems if yield distributions are outlier contaminated and heteroscedastic. While this conclusion is also valid for subsequent applications such as yield prediction and the estimation of expected indemnity payments, the difference between the considered estimators becomes less distinct. For these applications, we find particularly the M‐estimator to be a good compromise between high‐breakdown (very robust) estimators and the very efficient OLS‐estimator. Because no regression technique dominates all others in all applications and scenarios for error term distributions, our results underline that the choice of the estimation technique should be dependent on the purpose of the crop yield data analysis. However, alternative estimators such as M‐, MM‐, and TS‐estimator can reduce (and bound) the risk of unreliable or inefficient crop yield data analysis in crop insurance applications.     

长期护理保险在中国的选择-基于制度经济学的分析

为了解决人口老龄化背景下的老年护理问题,德国、日本先后于1995年1月1日、2000年4月1日启动长期护理保险制度。我国在1999年也已经进入老龄化国家行列,老龄化并呈加速趋势。我国农村家庭养老看护功能日益削弱、城镇养老机构数量不足、新型居家养老模式的资金来源不足。有必要借鉴德国、日本长期护理保险制度,采取城市的居家养老护理保险与农村的老年护理救助模式。基于制度经济学的角度,从价值支持、意识形态支持、成本支持与路径支持上论证了该制度的可行性。     

预期寿命、生育率变动与基本养老保险统筹账户调整

在构建三期世代交叠模型的基础上,通过选取相关制度指标来模拟分析在未来预期寿命和生育率变动下,基本养老保险统筹账户如何基于参数调整来维持收支平衡。研究结果表明：（1）我国居民预期寿命增长过快,统筹账户收支平衡受预期寿命变化影响较大;（2）在现阶段的预期寿命和生育率条件下,统筹账户能实现自身收支平衡,而且可在短期内通过阶段性降低缴费率来促进制度长远发展;（3）在长期内需通过提高缴费率或降低养老金替代率来保证统筹账户收支平衡,预期寿命为87.828岁且总和生育率为1.79作为参数调整临界点;（4）以现有制度设计为基准,参数调整临界点之前保证35%的基础养老金平均替代率不降,临界点之后保证20%的缴费率不升可以最大程度促进经济和社会发展。     

Risk management and reinsurance strategies in the Spanish insurance market (1880–1940)

Reinsurance allows insurance companies to diversify their risks. However, from this original role, insurance companies have developed various reinsurance strategies in order to expand their market share. From the last decades of the nineteenth century to the 1940s, Spanish insurance companies used reinsurance in a largely unregulated context. This article analyses the reinsurance practices and their adaptation to the singularities of the Spanish market, namely: the difficulties for the consolidation of a core of pure reinsurers; the management of reinsurance in the internationalisation process; and the use of reinsurance by mutual societies to overcome their lack of equity capital.     

The dynamic interactions among the stock,bond and insurance markets

This paper explores the lead–lag relationships and the dynamic linkages among stock, insurance and bond markets in the developed countries. This is the first empirical study which sheds light on the extent and magnitude of the association among these financial markets used by the Granger causality test of Toda and Yamamoto (1995), generalized impulse response approach, and generalized variance decomposition in a multivariate setting. Our empirical results illustrate that there are indeed various patterns of dynamic relationships. The direction of causality appears to differ across countries. While investigating these interactive relationships under unexpected shocks, there is a one-way significant influence between the life insurance premium and long-run interest rate. These empirical findings serve as valuable applications not only for investors to diversify their risk away as well as to earn the abnormal return, but also for policy-makers to allocate resources more efficiently.     

寿险合同持续期的实证研究:一个契约的视角

本文将寿险合同持续期,作为研究的对象。以契约经济学的方法,分析保险合同,将影响持续期的因素分为:投保人特点、保险人行为以及契约外部环境。运用来自山东某人寿保险公司的保单数据,研究了各类因素对持续期的影响。极大似然估计的结果显示,三类因素对寿险合同持续期都有显著影响。其中,服务质量、职业风险以及定期存款利率对契约持续的影响最大。另外,收入、年龄、同业竞争,也对持续期有显著影响。
