Why Do Some Households Save So Little? A Rational Explanation

This paper offers an explanation for the puzzle of low wealth holdings among a significant fraction of the elderly. Instead of invoking irrational, nonrational, or nonoptimal behavior to resolve the puzzle, it is shown that widespread low wealth holdings are consistent with a rational life-cycle model of saving with uncertain lifetime and borrowing constraint. When there is uncertainty about the length of life, it is optimal for some individuals to save little and exhaust their wealth early. The characteristics of these individuals are derived. The simulation results support that the model can account for low wealth holdings as well as early terminal wealth depletion. The analysis also rejects the common perception that uncertain lifetime reduces dissaving. Journal of Economic Literature Classification Numbers: D11, D91, E21, I12, J14.     

构建油田企业单项资产全寿命周期效益评价体系的思考

目前油田企业的资产管理方面存在诸多问题,如油气资产折旧、折耗及报废不合理,资产闲置严重,资产管理制度不完善及管理责任不够明确等问题。随着勘探开发的不断深入和企业自身的滚动发展,为了节减成本提高资产经营效率,油田企业需加强自身资产的管理。对于如何才能全面反映资产整个寿命周期各个阶段的管理状况,应该采用何种分析方法,评价指标、评价方法和评价标准进行构建评价体系等本文做了进一步的思考与探讨。     

Longevity and the life-cycle of management buy-outs

The longevity debate about buy-outs has hitherto been restricted. By focusing on large highly leveraged transactions, existing research has taken only a partial view of how long buy-outs last and the factors influencing longevity. This paper develops and tests hypotheses concerning the influences on buy-out longevity across the whole spectrum of management buy-out applications. Both quantitative and case study evidence from the U. K. is presented. A heterogeneity view of buy-outs is supported. Tests using quantitative data show that earlier exit is associated with larger buy-outs, and buy-outs arising on privatization from the public sector and from non-U. K. parents. Case study evidence principally supports hypotheses that earlier exit is associated with financing institutions being in a relatively stronger position than management and with more rapidly changing market conditions for the firm.     

大型光学设备全寿命周期管理软件设计与实现

当前中国战略性大型光学设备需求不断增大,传统的大型设备管理模式已经逐步影响了大型设备的维护和生产,迫切需要研制一种综合的全寿命周期管理软件,将生产与维护相结合,在对系统的维护过程中记录关键数据,以求在设备再生产或者改进中发挥经验作用.为了实现上述需求,采用基于客户机/服务器(Client/Server,C/S)模式的数据库技术,通过ACCESS软件建立数据库,通过C#语言连接并访问、修改数据库,使用WPF构建用户界面,开发了软件系统,实现了预期功能.通过实际使用,验证了全寿命周期管理软件的引入提高了大型光学设备的维护效率,方便了研发人员与用户之间的沟通.     

Transfers in Spanish State Retirement Pensions

A central issue in the recent reforms of state pensions in Spain has been to increase the proportionality between contributions and benefits along actuarially fair lines. The aim of this paper is to quantify the transfer component of social security retirement pensions, with transfer being understood as the difference between the pension effectively received and that which would be received under a system of actuarial fairness. The analysis is placed within a life-cycle framework, with particular reference to the distributive effects by income level. The results show that, in the past, there was a marked bias in favour of the objective of intergenerational and intragenerational redistribution, to the detriment of the objective of income insurance. This paper examines the factors that determine the final value of the transfer component within the entire Spanish pensions system.     

Market share instability and stock price volatility during the industry life-cycle: the US automobile industry

Market share instability, during certain stages of the industry life-cycle, has become a stylized fact in the industrial organization literature. In the finance literature, volatility in the form of excess volatility, i.e. the much larger volatility of stock prices than dividends (although stock prices should in theory trace the present value of future dividends), has given rise to controversies regarding stock price determination (Campbell and Shiller, 1988; Shiller, 1989). Recent evolutionary models, both theoretical and empirical, have tied the presence of market share instability to industry specific variables, such as specific periods in the industry life-cycle and specific “technological regimes”. The object of the paper is to explore whether there is a relationship between market share instability and stock price volatility and to what degree this relationship is connected to the concept of the industry life-cycle, and hence to industry specific factors. To do so, we explore the relationship in one particular industry, the US automobile industry. Since neither life-cycle nor finance theories attack this problem directly, we use insights from both approaches to build hypotheses which guide the data analysis. The empirical results confirm many of these hypotheses, suggesting that the degree of excess volatility is indeed partly affected by industry specific factors.

Competition in Marketing： Survival Yardstick for Small and Medium Enterprises （SMEs） in Nigeria

The topic investigated competition in marketing as a survival yardstick for small and medium enterprises （SMEs） in Nigeria. The objectives addressed by this study were： （1） identifying different types and intensity of competition that SMEs are exposed to along the life-cycle portfolio in Nigeria; （2） quantifying the strength of SMEs vis-a-vis some foreign enterprises in terms of market competition; and （3） proffering solutions on how best they could match competitively these foreign enterprises. Relevant models and theories were employed in literature to evolve detailed analysis of issues relating to the variables used in terms of competition in marketing and survival of juice-producing SMEs. Two hypotheses were investigated through the survey of 20 prominent Ikeja based SMEs using Cluster sampling, 5-points Likert summated rating scale was adopted, while Yard＇s formula with 95% confidence level and 5% error tolerance was used. Alternative form validity of the instrument was measured at 0.63 while its reliability was measured at Cronbach＇s alpha of 0.70. Pearson＇s product-moment correlation was used in testing hypothesis 1 while standard multiple regressions were used to test hypothesis 2. Findings revealed that there was strong relationship between survival of juice-producing SMEs with forms of competition on a firm＇s life-cycle; while competition had positive effects on survival components for the enterprises. It was concluded that since competition subsists in any firm＇s life-cycle, strategies to support operations for survival must be adopted. It was recommended that operators of SMEs have to monitor and manage competition as it affects their businesses positively and/or negatively.     

The Retirement Consumption in Korea: Evidence from the Korean Labor and Income Panel Study

Abstract

This paper examines the retirement consumption in Korea using the Korean Labor and Income Panel Study. This paper reports a significant post-retirement consumption fall among elderly households. The empirical results of this paper suggest that a reduction in work-related expenses is an important factor to explain the observed post-retirement consumption fall. In addition, this paper finds that the post-retirement consumption growth rate varies depending on each household's pre-retirement wealth level. The findings of this paper provide empirical evidence on retirement consumption in an emerging market with no matured public pension programmes.     

The effects of economic development and the evolution of social institutions on the level of corruption: comparing the Asia-Pacific with other regional blocs

ABSTRACT

The variation in the level of economic development across countries has been proposed as an explanation for the disparity in the level of corruption that is observed. As a country evolves from one stage of economic development to another and its social institutions as a result become more refined and sophisticated, their capacity to tackle corruption and poor governance practices becomes increasingly better. Improvements in the overall quality of institutions, including better policing and justice systems, increase their capacity to detect and deter corruption. This evolution of institutional quality improves social and economic well-being of society, which in turn pressures regulators, legislators and politicians to continue in the fight against corruption. The objective of this paper is to examine how economic development mediated by improvements in the quality of social institutions impacts on the level of corruption. Lessons from worldwide trends, including the Asia-Pacific region, provide opportunities for countries to enact strategic measures that can accelerate the fight against corruption.
