We consider a one-sector growth model in continuous time with a production externality and endogenous labor supply. There is a continuum of households who have identical preferences but differ with respect to their initial wealth. We show that there exist economies such that an indeterminate steady state exists for some wealth distribution but not for others. A second result is that a redistribution of wealth may drive the economy from a steady state with strictly positive output to a poverty trap in which output converges asymptotically to zero. These results indicate that differences in the wealth distribution may be responsible for drastic differences in the long-run standard of living.

Agency theory has established that appropriate incentives can reconcile the diverging interests of the principal and the agent.
Focusing on three applications, this dissertation evaluates the empirical relevance of these results when a third party interacts
with the primary contract. The analyses provided rely on either laboratory or natural experiments.
First, corruption is analyzed as a two-contract situation: a delegation contract between a Principal and an Agent and a corruption pact concluded between this Agent and a third player, called Briber. A survey of the recent microeconomic literature on corruption
first highlights how corruption behavior results from the properties of those two agreements. We thereafter show that the
Agent faces a conflict in reciprocities due to those two conflicting agreements. The resulting delegation effect, supported by observed behavior in our three-player experimental game, could account for the deterrence effect of wages on
corruption.
Second, health care is governed by contradictory objectives: patients are mainly concerned with the health provided, whereas
containing health care costs is the primary goal of health care administrators. We provide further insights into the ability
of incentives to balance these two competing objectives. In this matter, our theoretical and econometric analysis evaluates
how a new mixed compensation scheme, introduced in Quebec in 1999 as an alternative to fee-for-services, has affected physicians’
practice patterns. Free switching is shown to be an essential feature of the reform, since it implements screening between
physicians.
Finally, the demand for underground work departs from the traditional Beckerian approach to illegal behavior, due to the dependence
of benefits from illegality on competitors’ behavior. We set up a theoretical model in which the demand for underground work
from all producers competing on the same output market is analyzed simultaneously. We first show that competition drastically
undermines the individual benefits of tax evasion. At equilibrium, each firm nonetheless chooses evasion with a positive probability,
strictly lower than one. This Bertrand curse could then account for the “tax evasion puzzle” i.e. the overprediction of evasion in models that ignore market interactions.
We thereafter show that allowing firms to denounce competitors’ evasion is not likely to solve this curse—by providing a credible
threat against price cuts, it fosters illegal work. Empirical evidence from a laboratory experiment confirms these predictions.
Without denunciation, experimental firms often choose evasion whereas evasion benefits are canceled out by competition. When
introduced, denunciation is rarely used by firms, but the threat makes evasion profitable.

针对由单制造商和单销售商组成的供应链,提出了供应链双方需求信息对称情况下的激励机制模型,并在此基础上建立了供应链双方在需求信息不对称情况下的运作策略模型。制造商通过折扣,运用激励相容机制使销售商诚实申报需求信息,使得供应链利润最大化的同时供应链成员实现双赢。数字试验结果表明:①所提策略是有效的;②该策略不仅能提高制造商利润,而且也能改善销售商的利润。 相似文献

绿色供应链管理的系统研究 总被引:11,自引:0,他引:11
人口、资源与环境三者之间的矛盾日益突显,要求企业的经营活动必须与环境相容。绿色供应链管理是从可持续发展的思想出发解决制造业与环境之间冲突的有效方式,是一种现代企业的可持续发展模式。目前绿色供应链的研究刚刚开始,尚未形成理论体系。进行绿色供应链管理的研究对提高产品在国际市场上的竞争力、保护环境和实施可持续发展战略具有十分重要的意义。 相似文献

在供电企业电力营销效果综合评价中,客观赋权法体现了指标的信息量,而主观赋权法体现了指标的价值量,综合评价应当体现二者的统一.针对电力营销效果评价,提出了基于组合权的灰色关联分析方法.对传统的灰色关联法进行改进,将该方法用于供电企业电力营销效果评价,得到了较好的结果. 相似文献

循环经济是当前世界经济发展的主要方向,已被我国确定为今后经济的发展模式。本文根据绿色供应链管理的定义、内涵和循环经济"3R"原则,设计出基于循环经济绿色供应链管理绩效评价指标体系,即将绿色信息作为绿色供应链管理绩效评价的主要衡量指标之一,并将各个指标具体化,形成一个二级指标评价体系。根据指标体系的特点进行模糊多层次综合评价,最后给出一个算例进行说明,为基于循环经济的绿色供应链管理绩效评价提供了理论依据。 相似文献
