X-低效率分析是社会保障政策目标分析的一个新的研究视角。"漏桶理论"天然地诠释了社会保障X-低效率存在的原因,社会保障制度作为社会的稳定器和安全网,其政策效率目标在运作过程中会产生一定漏出量,引发X-低效率现象。政府失灵、制度设计管理缺陷、道德风险与负面激励共同构成了社会保障政策目标X-低效率的客观诱因。 相似文献

理论上讲我国实施股票期权可以有效解决经理人长期激励不足和经营者道德风险问题,也有利于上市公司降低委托成本,吸引并稳定人才.但由于我国股票市场不完善及股东与管理者的信息不对称等问题的存在,股票期权激励机制在我国的运用效果欠佳,从而产生了激励陷阱.文章通过对股权激励陷阱表现形式及形成原因的分析,提出了规避此类陷阱的具体措施. 相似文献

In the dynamic model of banking, a bank's option to hide its loan losses by rolling over non-performing loans is shown to worsen moral hazard. Contrary to the classic theory, moral hazard may arise even when a bank cannot seek a correlated risk for its loans. The loans seem to be performing and the bank makes a profit although it is de facto insolvent. When the bank's balance sheet includes hidden non-performing loans, the bank may optimally shrink lending or gamble for resurrection by growing aggressively. To eliminate this type of moral hazard, which is broadly consistent with evidence from emerging economies, a few regulatory implications are suggested. 相似文献

We examine the coexistence of banks and financial markets by studying a credit market where the qualities of investment projects are not observable and the investment decisions of entrepreneurs are not contractible. Standard banks can alleviate moral‐hazard problems, while financial markets operated by investment banks can alleviate adverse‐selection problems. In competition, standard banks are forced to increase repayments, since financial markets can attract the highest‐quality borrowers. This, in turn, increases the share of shirkers and may make lending unprofitable for standard banks. The coexistence of financial markets and standard banks is socially inefficient. The same inefficiency may occur with the entrance of sophisticated banks, operating with a combination of rating and ongoing monitoring technologies. 相似文献

Characteristic properties of multivariate survival functions in terms of residual life distributions
Chunsheng Ma 《Metrika》1998,47(1):227-240
This paper discusses the relationships among some characteristic properties of the multivariate survival function based on
the residual life distribution, and provides the conditions for their equivalence. In the meanwhile, the corrected version
of Ma (1996, Theorem 1 (ii) and (iii)) is given. 相似文献

This paper uses a proportional hazard model to study foreign direct investment by Japanese manufacturers in Europe between
1970 and 1994. We divide each firm’s investment total into a sequence of individual investment decisions and analyze how firm-specific
characteristics affect each decision. We find that total factor productivity is a significant determinant of a firm’s initial
and subsequent investments. Parent-firm size does not have a significant influence on the initial decision to invest. Large
firms simply have more investments than smaller firms. Other firm-specific characteristics, such as the R&D intensity, export
share and keiretsu membership, also play a role in the investment process.

Burnout is a consequence of unobservable predictive variables. This paper describes a methodology for estimating mortgage prepayment models which corrects for burnout. The paper generalizes the approach of Deng, Quigley, and Van Order (Econometrica, 68, 275–307, 1998) and Stanton (Rev. Finan. Stud.8, 677–708, 1995) in modeling the impact of unobservable variables as a probability distribution. The estimator is applied to a sample of loan histories and the results compared to a conventional logit analysis of the data. Predictions and simulations from both models are compared to illustrate the properties of the new estimator. 相似文献

This paper presents an analytically tractable valuation model for residential mortgages. The random mortgage prepayment time is assumed to have an intensity process of the form h t = h 0 ( t ) +γ ( k − r t )+ , where h 0 ( t ) is a deterministic function of time, r t is the short rate, and γ and k are scalar parameters. The first term models exogenous prepayment independent of interest rates (e.g., a multiple of the PSA prepayment function). The second term models refinancing due to declining interest rates and is proportional to the positive part of the distance between a constant threshold level and the current short rate. When the short rate follows a CIR diffusion, we are able to solve the model analytically and find explicit expressions for the present value of the mortgage contract, its principal-only and interest-only parts, as well as their deltas. Mortgage rates at origination are found by solving a non-linear equation. Our solution method is based on explicitly constructing an eigenfunction expansion of the pricing semigroup, a Feynman-Kac semigroup of the CIR diffusion killed at an additive functional that is a linear combination of the integral of the CIR process and an area below a constant threshold and above the process sample path (the so-called area functional). A sensitivity analysis of the term structure of mortgage rates and calibration of the model to market data are presented. 相似文献

银行存款保险制度自1933年在美国实施以来,已为世界上70多个国家所效仿,其在避免因银行倒闭引发储户挤兑、保障存款人存款安全及维护金融秩序稳定方面,确实功不可没。但是,一些国家银行存款保险制度中存在的“道德风险”、“逆向选择”及“大则不倒”等问题,客观上影响了存款保险制度功效的发挥。为此笔者提出了实施基于风险的差别费率制及采取强制性投保方式等法律对策。 相似文献

We analyze the factors that influence the decision to secure a commercial loan. We find evidence that variables reflecting adverse selection, moral hazard, and the prospects for default all affect the likelihood a loan will be collateralized. We find no evidence in favor of the predictions of certain theoretical models that high‐quality firms signal by providing collateral. Our results also show that lenders with less risk protection in the form of equity capital are more likely to require collateral, but that banks themselves are less likely to secure loans than nonbanks. Certain loan characteristics also influence the collateralization decision. 相似文献
