我国权利质权制度的完善思考

权利质权制度作为我国担保法的一个组成部分在市场经济中发挥着十分重要的作用,现行《担保法》及相关司法解释的缺陷影响了该制度功能的发挥。为了进一步发挥该制度的担保功能,需要进一步完善权利质权的标的种类、完善权利质权的设定方式、完善权利质权的效力制度、完善实行制度及相关的配套制度。     

Bayesian incorporation of repeated measurements in logistic discrimination

A common problem in medical statistics is the discrimination between two groups on the basis of diagnostic information. Information on patient characteristics is used to classify individuals into one of two groups: diseased or disease-free. This classification is often with respect to a particular disease. This discrimination has two probabilistic components: (1) the discrimination is not without error, and (2) in many cases the a priori chance of disease can be estimated. Logistic models (Cox 1970; Anderson 1972) provide methods for incorporating both of these components. The a posteriori probability of disease may be estimated for a patient on the basis of both current measurement of patient characteristics and prior information. The parameters of the logistic model may be estimated on the basis of a calibration trial. In practice, not one but several sets of measurements of one characteristic of the patient may be made on a questionable case. These measurements typically are correlated; they are far from independent. How should these correlated measurements be used? This paper presents a method for incorporating several sets of measurements in the classification of a case.     

Optimal Prediction in Stochastic Regression Models with Application to the Analysis of Repeated Surveys

Several results relating to the optimal prediction of regression coefficients and random variables under a general linear model with stochastic coefficients are presented. These results are then applied to the analysis of repeated sample surveys over time. In particular, if the finite population can be modelled by a superpopulation model, a fully efficient method for the analysis of repeated surveys is proposed.     

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.     

A rank test for stochastically ordered alternatives

A rank test based on the number of ‘near-matches’ among within-block rankings is proposed for stochastically ordered alternatives in a randomized block design with t treatments and b blocks. The asymptotic relative efficiency of this test with respect to the Page test is computed as number of blocks increases to infinity. A sequential analog of the above test procedure is also considered. A repeated significance test procedure is developed and average sample number is computed asymptotically under the null hypothesis as well as under a sequence of contiguous alternatives.     

Multivariate analysis with a stationary time series covariance structure

When a covariance matrix has a pattern associated with a stationary time series on the errors, it is shown how certain hypothesis testing problems In multivariate analysis can be transformed into a product of two similar multivariate problems that each involve unpatterned covariance matrices.     

Repeated measurements designs - a review

Any experiment in which one or more of the experimental units is used more than once is called a repeated measurements experiment. The associated design of a repeated measurements experiment is referred to as a repeated measurements design. This review covers some known results on repeated measurements designs. Emphasis is placed on the impact of optimal design theory. Some construction methods for these designs are presented. Hedayat and Afsarinejad (1975) has an extensive bibliography of earlier literature. A bibliography of these designs published after 1974 is provided at the end of this paper.     

农地确权能够在农村信贷市场发挥“德·索托效应”吗？——兼论中国农地抵押之佯谬

理论分析农地确权发挥德·索托效应的作用机理及其服务边界,同时兼论实践中的中国农地抵押之佯谬,以此综合评估确权后中国农地金融改革能否有效缓解农村信贷市场的融资约束难题,由此也延伸出对创新农村融资模式以满足农户融资需求的进一步讨论。分析表明,农地确权的德·索托效应在农村信贷市场尚不能完全发挥,其对融资约束的缓解作用在信贷需求端“有效”,而在信贷供给端“有限”,农户融资需求无法有效转化为实际供给。分析现阶段中国农地抵押的法律困境和委托代理问题发现,中国农地抵押改革在实践过程中存在佯谬,致使农地确权的德·索托效应在信贷供给端受限：一是外部环境尚未建立起服务于农地抵押的配套制度与措施,导致农地经营权无法成为金融机构认可的合格抵押品;二是农商行二元目标不一致及其与农户之间的信息不对称致使农地抵押贷款“失灵”。最后,建议加强农地金融改革的顶层设计,深化农地金融改革与缓解融资约束的有效对接;另外,可从抵押替代机制角度,探析缓解农村融资约束困境的创新模式。
