金融知识获取圈层对农户农地抵押贷款参与的影响研究——基于失地风险感知的中介效应分析

积极稳妥推广农地抵押贷款融资业务,持续深化农村土地资产与金融资源的有机衔接是完善金融服务乡村振兴战略的关键内容,深入探究农户金融知识获取的人际圈层来源以及失地风险感知因素对完善农地抵押贷款相关制度建设具有重要意义。文章首先理论阐释了金融知识获取圈层、失地风险感知对农户农地抵押贷款参与的影响,详细剖析了农户失地风险感知的中介机理;然后采用因子分析法测度金融知识获取圈层变量,提取4个公共因子分别界定为亲属关系圈、朋友关系圈、乡邻关系圈和机构参与圈;最后以陕西、宁夏、山东三省农地抵押贷款试点地区1 312户农户调查数据为样本,利用Logit模型和Bootstrap中介效应检验方法,实证分析了金融知识获取圈层、失地风险感知对农户农地抵押贷款参与的影响,并揭示了失地风险感知的中介效应类型和数值大小。研究结果显示：金融知识获取圈层正向促进农户农地抵押贷款参与,其中金融知识获取亲属关系圈的促进作用大于机构参与圈;金融知识获取圈层负向影响农户失地风险感知,机构参与圈的影响最大,亲属关系圈次之,朋友关系圈最小;在四个金融知识获取圈层下,失地风险感知均对农户农地抵押贷款参与具有负向影响;失地风险感知在金融...     

文化意象的失落与扭曲:诗歌翻译之忌

意象是诗歌的生命,当意象涉及到某种文化的深层意蕴,这个意象就成为文化意象.在诗歌翻译中,对原作的文化意象进行任意取舍或扭曲都是不当的.对原作物象的尊重才是诗歌文化意象翻译的正途.     

经理行为偏差与企业绩效激励指标的确定

股东在面对具有行为偏差的经理时,如何设计剩余收益作为激励指标,以促使双方的目标一致,一直是学界和实务界关注的一个问题。如果股东继续沿用传统的基于公司资本成本率计算得到的剩余收益,将使得损失厌恶的经理投资不足,过度自信的经理投资过度。为了改进投资决策,股东需要针对不同行为特征类型的经理设计较公司资本成本率更低或更高的激励相容资本成本率,以有效激励经理做出符合股东利益的投资决策。     

中国股票市场风险因素相关性研究

在传统的多元回归模型基础上,利用动态模型并结合分位数模型,研究了中国股票市场的风险因素如公司规模、账面市值比和流动性之间的相关性。研究结果表明,在考虑了流动性的滞后影响后,公司规模与其股票流动性之间存在显著的正相关关系,而账面市值比与股票流动性之间存在显著的负相关关系,进而揭示了流动性溢价理论可以解释股票市场中的规模效应和价值效应的原因。     

A class of weighted dependence measures for bivariate failure time data

This paper considers a class of summary measures of the dependence between a pair of failure time variables over a finite follow-up region. The class consists of measures that are weighted averages of local dependence measures, and includes the cross-ratio-measure and finite region version of Kendall's τ; recently proposed by the authors. Two new special cases are identified that can avoid the need to estimate the bivariate survivor function and that admit explicit variance estimators. Nonparametric estimators of such dependence measures are proposed and are shown to be consistent and asymptotically normal with variances that can be consistently estimated. Properties of selected estimators are evaluated in a simulation study, and the method is illustrated through an analysis of Australian Twin Study data.     

对国有资产中有形资产流失问题的探讨

国有资产中有形资产的流失存在动态流失与静态流失两种形式,动态流失因产权不清、管理不严或产权交易中规则不健全所致,具体又可分为经营性动态流失和人为性动态流失．静态流失与其是否进入市场交易有关．加强经济立法,完善和发展产权交易市场等可减少或避免国有有形资产的流失。     

Correlation in a Bayesian framework

The authors consider the correlation between two arbitrary functions of the data and a parameter when the parameter is regarded as a random variable with given prior distribution. They show how to compute such a correlation and use closed form expressions to assess the dependence between parameters and various classical or robust estimators thereof, as well as between p‐values and posterior probabilities of the null hypothesis in the one‐sided testing problem. Other applications involve the Dirichlet process and stationary Gaussian processes. Using this approach, the authors also derive a general nonparametric upper bound on Bayes risks.

A new heteroscedastic regression to analyze mass loss of wood in civil construction in Brazil

A heteroscedastic regression based on the odd log-logistic Marshall–Olkin normal (OLLMON) distribution is defined by extending previous models. Some structural properties of this distribution are presented. The estimation of the parameters is addressed by maximum likelihood. For different parameter settings, sample sizes and some scenarios, various simulations investigate the performance of the heteroscedastic OLLMON regression. We use residual analysis to detect influential observations and to check the model assumptions. The new regression explains the mass loss of different wood species in civil construction in Brazil.     

A multivariate zero-inflated binomial model for the analysis of correlated proportional data

In this paper, a new multivariate zero-inflated binomial (MZIB) distribution is proposed to analyse the correlated proportional data with excessive zeros. The distributional properties of purposed model are studied. The Fisher scoring algorithm and EM algorithm are given for the computation of estimates of parameters in the proposed MZIB model with/without covariates. The score tests and the likelihood ratio tests are derived for assessing both the zero-inflation and the equality of multiple binomial probabilities in correlated proportional data. A limited simulation study is performed to evaluate the performance of derived EM algorithms for the estimation of parameters in the model with/without covariates and to compare the nominal levels and powers of both score tests and likelihood ratio tests. The whitefly data is used to illustrate the proposed methodologies.
