The maxims of normative ethics are often in conflict. Thus business practitioners facing ethical questions often find themselves
operating in the area of relative ethics. There are arguably two dimensions to this area. One lies on a spectrum from weak
companies in highly competitive industries to strong companies in protected industries. The second dimension places the would-be
ethical manager in awkward situations imposed from either the hierarchy or from corrupt markets. This article develops an
analysis model to portray this relative ethics dilemma. Then, an argument is made that the more the individual manager practices
good ethics, the higher the level of ethics the individual is able to maintain. This article proposes an adaptation of the
1950s feedback model of group dynamics known as the “Johari Window” to show this improvement in ethical behavior. 相似文献

一、投资总体形势呈现积极变化2004年上半年,我国城镇固定资产投资累计完成21844亿元,同比增长31%,增速比1—5月份又下降了3.7个百分点。各类投资资金来源增速回落更为明显。与1—5月份相比,上半年累计的国内贷款、外商直接投资和自筹资金增速分别回落了7.2个、1.3个和7.6个百分点。在趋于中性的财政政策和偏紧的货币政策的共同作用下,市场资金供应向更加理性化的方向发展。从不同投资主体情况看,国有、集体、股份公司、外商投资、港澳台资和个体私营投资均出现了较为明显的投资增速回落,其中,集体经济、有限责任公司、股份有限公司、私营企… 相似文献

已有的基于风险的LCCBA中的收益概率模型构建需要较多的案例数据积累,而目前我国旅游投资决策分析总体上处于起步阶段,缺少相应的数据积累。本文对比分析各种现有投资决策分析方法之后,得出基于Shackle模型的不确定条件下的旅游投资决策方法更适用于我国当前的旅游投资分析,并通过Monte Carlo仿真的方法分析了该方法的有效性。不同于基于风险的LCCBA,该方法不需构建完整的收益概率模型,仅需估算出收益分布范围,就可以客观地对投资项目进行经济性分析,因而更适用于我国当前情况下的旅游投资决策分析。 相似文献

托宾q值影响投资了吗?——对我国投资理性的另一种检验 总被引:4,自引:0,他引:4
丁守海 《数量经济技术经济研究》2006,23(12):146-155
托宾曾预言,企业资产的边际q值是决定投资的重要因素。这一假说是否成立一直是理论界的一个谜,而对它的检验可大致反映一国投资的理性程度。本文利用结构向量自回归模型,分析了我国投资与q值之间的关系。结果表明,无论是短期的冲击响应,还是长期的协整关系,托宾q假说均不成立。相反,存在明显的“反托宾q”现象。这说明我国投资具有相当的非理性成分。进一步的分析表明,q值在行业间的分布差异与垄断行业的投资保护,以及过度竞争行业的投机行为相互交织,是造成上述结果的主要原因。由此本文提出了加快垄断行业投资体制改革、合理引导企业资金的政策建议。 相似文献

消费需求与投资需求协调增长 总被引:4,自引:0,他引:4
刘向农 《数量经济技术经济研究》2002,19(12):44-46
经济增长的动力,从根本上讲来自需求。需求增长与经济增长之间的相关关系十分显著。从扩大内需的两个主要内容--投资需求与消费需求对经济增长作用的特点来看,投资需求对经济增长的短期拉动作用十分明显,但要保证经济增长的质量并保持今后经济长期、快速、健康发展,仅仅依靠投资的增长是不够的,还必须要保证消费需求的协调增长。促进消费需求增长是提高经济增长质量的关键,因此应把鼓励和促进消费作为拉动经济增长的重大措施,作为当前经济工作的一项重要内容。 相似文献

我国农业投资现状评价及政策建议 总被引:11,自引:0,他引:11
我国农业投资的持续增长对农业发展起了重要作用,但投资数量明显不足,且波动较大.其中财政支农、农户和集体、民间资本以及信贷对农业的投入都有待加强和调整,农业投资机制和投资环境都不够完善.据此,政府应明确扶持农业发展的责任,并加大对农业的投资力度,明确在新时期农业投资的重点,加大民间资本和信贷资金对农业的投入,改善农业投送环境和投资机制. 相似文献

Two popular approaches for efficiency measurement are a non-stochastic approach called data envelopment analysis (DEA) and a parametric approach called stochastic frontier analysis (SFA). Both approaches have modeling difficulty, particularly for ranking firm efficiencies. In this paper, a new parametric approach using quantile statistics is developed. The quantile statistic relies less on the stochastic model than SFA methods, and accounts for a firm's relationship to the other firms in the study by acknowledging the firm's influence on the empirical model, and its relationship, in terms of similarity of input levels, to the other firms.

This paper considers the problem of choosing among the technologies available for irrigation by tubewells to obtain an investment plan which maximizes the net agricultural benefits from a proposed project in a developing country. Cost and benefit relationships are derived and incorporated into a mathematical model which is solved using a modification of the dynamic programming procedure for solving the knapsack problem. The optimal schedule is seen to favor small capacity wells, drilled by indigenous methods, with supplementary water distribution systems. 相似文献

The Institutional Environment for Telecommunications Investment 总被引:6,自引:0,他引:6
This paper demonstrates that a structurally derived, internationally comparable index of checks and balances on executive discretion created by variation in political structures and party systems affects relative rates of basic telecommunications infrastructure deployment in 147 countries during the period 1960–1994. Models of infrastructure investment that omit the political characteristics of a prospective host country confound countries whose economic and demographic characteristics point to rapid demand growth for infrastructure services with those that create a potential trap for investors due to a higher probability of arbitrary change in the policy environment. The econometric analysis exploits both cross-sectional and temporal variation in the panel. A robust covariance-matrix estimator based on that developed by Newey and West is used to compute valid standard errors in the presence of heteroskedasticity and within unit-serial correlation, two common characteristics in the error-term structure of panel datasets. 相似文献

This paper outlines a theory of project appraisal wherein the neoclassical premises of conventional cost-benefit analysis are replaced by their Keynesian counterparts. The paper shows how the social rate of return on public and private investment, the private and social discount rates, and other concepts used in cost-benefit analysis may be modified to take account of the income externalities generated by the multiplier, mark-up pricing, and the causal priority of investment over saving.
