体制转轨国家腐败与反腐败的经济学分析   总被引:7,自引:0,他引:7  
中国社会正处于体制转轨的关键时刻 ,转轨本身产生出过多的任意处置权 ,腐败的现实成本和机会成本都很低 ,造成了腐败在转轨国家滋生蔓延。转轨国家要保证反腐败的有效性 ,就必须有效降低反腐败的成本 ,增大腐败的成本 ,今后反腐败措施是 :1.要加快市场化改革进程 ,减少任意决策权 ,缩小政府规模 ;2 .要对政府官员进行有效激励 ,实行“养廉工资” ,以期加大革职的代价 ;3.要通过一系列制度建设 ,对政府官员进行有效的监督和约束 ,以增加腐败的现实成本。  相似文献

衍生金融工具因具有高风险性、时态未来性及品种多样性等特点,其计量问题一直是会计核算的核心和难点。传统的会计计量理论和方法已无法满足其要求。为此,有必要改进现行的会计核算体制,以公允价值取代历史成本对衍生金融工具进行计量,以增强信息披露的力度。  相似文献

Seismic risk can be reduced by implementing newly developed seismic provisions in design codes. Furthermore, financial protection or enhanced utility and happiness for stakeholders could be gained through the purchase of earthquake insurance. If this is not so, there would be no market for such insurance. However, perceived benefit associated with insurance is not universally shared by stakeholders partly due to their diverse risk attitudes. This study investigates the implied seismic design preference with insurance options for decisionmakers of bounded rationality whose preferences could be adequately represented by the cumulative prospect theory (CPT). The investigation is focused on assessing the sensitivity of the implied seismic design preference with insurance options to model parameters of the CPT and to fair and unfair insurance arrangements. Numerical results suggest that human cognitive limitation and risk perception can affect the implied seismic design preference by the CPT significantly. The mandatory purchase of fair insurance will lead the implied seismic design preference to the optimum design level that is dictated by the minimum expected lifecycle cost rule. Unfair insurance decreases the expected gain as well as its associated variability, which is preferred by risk-averse decisionmakers. The obtained results of the implied preference for the combination of the seismic design level and insurance option suggest that property owners, financial institutions, and municipalities can take advantage of affordable insurance to establish successful seismic risk management strategies.  相似文献

"黔电送粤"中水电真实移民成本问题研究   总被引:2,自引:0,他引:2  
现行“黔电送粤”的电价未能反映真实移民成本。理应在厘清真实移民成本主要组成部分的基础上,在谈判和核定电价时加以考虑,促使真实移民成本成为电价的构成要素,这对于解决各族移民的脱贫致富,具有重要意义。  相似文献

We describe a risk-based analytical framework for estimating traffic fatalities that combines the probability of a crash and the probability of fatality in the event of a crash. As an illustrative application, we use the methodology to explore the role of vehicle mix and vehicle prevalence on long-run fatality trends for a range of transportation growth scenarios that may be relevant to developing societies. We assume crash rates between different road users are proportional to their roadway use and estimate case fatality ratios (CFRs) for the different vehicle-vehicle and vehicle-pedestrian combinations. We find that in the absence of road safety interventions, the historical trend of initially rising and then falling fatalities observed in industrialized nations occurred only if motorization was through car ownership. In all other cases studied (scenarios dominated by scooter use, bus use, and mixed use), traffic fatalities rose monotonically. Fatalities per vehicle had a falling trend similar to that observed in historical data from industrialized nations. Regional adaptations of the model validated with local data can be used to evaluate the impacts of transportation planning and safety interventions, such as helmets, seat belts, and enforcement of traffic laws, on traffic fatalities.  相似文献

Informal caregivers of individuals with Alzheimer's disease spend a considerable amount of time providing care. In this paper, we use Grossman's health production and Becker's time allocation models to develop a model of informal care provision to elderly dementia patients. In our model, time inputs produce caregiving services, which provides utility to the caregiver, but reduces leisure. We assume that time is less productive of services on the margin as the disease progresses. In this framework, an increase in patients' disease severity does not necessarily increase informal caregiver time input. The cost of formal care establishes a reservation price for informal caregiving. When the costs of informal caregiving rise above this reservation level, the patient is institutionalized. We test empirically the effect of deterioration in the patients' condition, proxied by both disease severity and dementia problem behavior, on informal caregiving time. We find that dementia-related problem behaviors and functional limitations significantly increase inputs of informal caregiving time. Patients' problem behavior exerts a modifying effect on functional limitations, and patients' comorbidities have no effect on informal caregiving time.  相似文献
