Applications of Fuzzy Regression in Actuarial Analysis

In this article, we propose several applications of fuzzy regression techniques for actuarial problems. Our main analysis is motivated, on the one hand, by the fact that several articles in the financial and actuarial literature suggest using fuzzy numbers to model interest rate uncertainty but do not explain how to quantify these rates with fuzzy numbers. Likewise, actuarial literature has recently focused some of its attention in analyzing the Term Structure of Interest Rates (TSIR) because this is a key instrument for pricing insurance contracts. With these two ideas in mind, we show that fuzzy regression is suitable for adjusting the TSIR and discuss how to apply a fuzzy TSIR when pricing life insurance contracts and property‐liability policies. Finally, we reflect on other actuarial applications of fuzzy regression and develop with this technique the London Chain Ladder Method for obtaining Incurred But Not Reported Reserves.     

Internal validity assessment of conjoint estimated attribute importance weights

This paper investigates how various conjoint designs (full versus fractional) and estimation procedures (LINMAP, MONANOVA, OLS) may interact with basic characteristics of the “true” utility functions (i.e., their range, shape, and curvature) when estimating attribute importance weights. Substantial weight distortions are found, especially under a fractional design.     

Sequential bargaining in a market with one seller and two different buyers

A matching and bargaining model in a market with one seller and two buyers, differing only in their reservation price, is analyzed. No subgame perfect equilibrium exists for stationary strategies. We demonstrate the existence of inefficient equilibria in which the low buyer receives the good with large probability, even as friction becomes negligible. We investigate the relationship between the use of Nash and sequential bargaining. Nash bargaining seems applicable only when the sequential approach yields a unique stationary strategy subgame perfect equilibrium.     

《中华人民共和国中国人民银行法》需要进一步完善

面对加入WTO的现实，应付混业监管的需要，人民银行应当在性质、职责、独立性和货币政策目标上重新定位。建立政府的金融综合监管部门，健全金融监管体系，加强货币政策委员会的职能，使人民银行能充分发挥中央银行的职能。     

物资进出口贸易管理概论

我国加入WTO,船舶工业和国际经济的关系更为密切,我国船厂及其船用配套厂拥有更多的出口机遇,外国船厂及其船用配套厂将会登陆中国市场。船舶物资进出口贸易的比例会不断提高,国内船舶物资市场将逐步和国际船舶物资市场融为一体。因此,我国船舶行业的各级管理人员,特别是物资管理工作者,必须掌握物资进出口贸易的常用术语,了解进出口贸易的一般过程,弄清交

Regulation of the iberoatlantic sardine fishery

The basic aim of this paper is to use a case study to illustrate the way in which controls can achieve an optimum exploitation of marine resources. The specific fishery under study is the Iberoatlanti sardine fishery. A bioeconomic deterministic model for this fish resource is developed and applied. The most relevant results and estimates are showed. Finally, we present some economic policy recommendations for the fishery, as well as considerations for the application of the regulatory measures.I thank M. C. Gallastegui for all his help. I also thank the anonymous referees for helpful comments and suggestions.

An Examination of the Quality of Jobs in the Call Center Industry

This paper examines jobs in the information society and the new economy, taking as its focus the call center industry. More specifically, the study analyzes the degree of variability of the quality of call center jobs. In order to achieve this objective, an index of job quality is generated, and an empirical analysis of the characteristics of jobs in call centers is carried out. This allows us to determine the level and variability of quality of jobs in this sector and to establish whether the reality of these jobs is as good as the forecasts for work in the new economy.      

Research on the development and countermeasures for circular economy

Ecological economics and sustainable development economics are the basic theories to research on circulareconomy. Through the systemically research on the relationship of the three above, this paper thinks that the reuse andrecycle of circular economy is a way that the stall is mended after a sheep is lost. Although the reduction technicallycontrols the production process, it cannot solve the waste caused by blind production and excess competition. We haveexperienced variety obstacles when implementing the circular economy, whose main reason is the conflict between theindividual ration and the social ration. Therefore, only when the individual ration and social ration incline to conformity,the cooperating Nash equilibrium will be appeared. In order to realize the harmony of ecology, economy and society, wehave to explore effective evaluation theory. This paper cites the ＂five flows of wealth operation theory＂ from professorMa Chuandong to search operation mechanism of circular economy, makes clear the developing thoughts of circulareconomy based on the realities, and brings forward some countermeasures to develop circular economy based on theabove theoretical analysis.
