A model of local labor market regulation of China in the transition period

With the establishment of labor market of China, market is playing a more and mare important role in allocation of human resources. However, with the transition of economy in China and industrial upgrading in recent years, many labor problems have occurred which do harm to the sustainable development of local economy. The paper researches on the labor market issues of China from the perspective of local labor market regulation. Firstly, it reviews the theories of local labor market regulation. And then the main components of local labor market regulation of China are identified and the evaluation index system is established. The results of analysis of the calculated output show that （1） the local labor market regulation of China has an obvious character of gradient distribution geographically and decreases gradually from east to west; （2） of all the regulations, the regulation of the development of human capital has the most significant impact on local economy currently which is followed by the regulation of labor relation and the regulation of market participation. As to the regulation of social security, it has no Significant impact on the development of local economy.     

The economic burden of advanced Parkinson’s disease: an analysis of a UK patient dataset

Abstract

Background:

To evaluate the cost burden of patients with advanced Parkinson’s disease (PD) according to the waking hours per day spent in OFF state. An analysis of resource use comprising medical services, professional care and informal care data from an observational, cross-sectional study was conducted.

Methods:

A total of 60 physicians comprising 40 neurologists and 20 geriatricians across the UK participating in the Adelphi PD Disease Specific Programme took part. There were 302 PD patients at H&Y stages 3–5. Patients were characterised according to the percentage of time per day spent in OFF state (<25%, 26–50%, 51–75%, >75%).

Results:

Average 12-monthly total costs increased according to the time spent in OFF state from £25,630 in patients spending less than 25% of their waking hours in OFF to £62,147 for patients spending more than 75% of their time in OFF. Overall, 7% of costs were attributed to direct medical care, while 93% were split between direct non-medical professional care (50%) and indirect informal care (43%).

Limitations:

Low patient numbers in the more advanced disease stages of PD led to very little or no data to directly inform some of the severe health states of the analysis. Data gaps were filled in with data derived from a regression analysis which may affect the robustness of the analysis.

Conclusion:

This study illustrates the increasing costs of advancing PD, in particular related to the time spent in OFF state, and identifies that the foremost cost burden is associated with the care needs of the patient rather than medical services.     

Health-related quality-of-life in patients after elective surgery for abdominal aortic aneurysm

Abstract

Purpose:

The purpose of this study was to describe the health-related quality-of-life (QoL) in patients after elective surgery for abdominal aortic aneurysm (AAA) compared to a normal population and to study the association between QoL and number of years since surgery.

Methods:

All Danish men who underwent elective surgery for AAA at the age of 65 or more in the period from 1989–2007 in Denmark were invited to participate in the survey. Of 722 patients, 375 were alive and 328 (87%) responded. The instruments EQ-5D (European Quality of life), EQ-VAS and SF-12 (Short Form Health Survey) were applied for measuring health-related QoL. Multiple regression analysis was used to study the association between QoL and number of years since AAA surgery.

Results:

A significantly poorer QoL was found in patients having had AAA surgery compared to the normal population as measured with the SF-12 and the EQ-VAS, but not with EQ-5D. A negative association between QoL and years following surgery was found with EQ-VAS and SF-12 (PCS), but not with the other instruments.

Discussion:

Factors such as selection bias because of mortality and non-response may have resulted in an over-estimate of the QoL in patients having had AAA surgery, thus the difference in QoL compared to the normal population was probably under-estimated. The cross-section design was inefficient for the study of the association between QoL and years since surgery, and EQ-5D may be an insensitive instrument for measuring QoL in AAA patients after surgery.

Limitations:

The main limitation of the study was the cross-sectional design. Males with a higher risk of death were under-represented in the sample.

Conclusion:

A poorer quality-of-life was found in patients having had elective AAA surgery compared to the normal population.     

交易成本与新型农村合作医疗制度可持续发展

新型农村合作医疗制度的试点极大地推进了我国农村医疗保障制度的构建过程,但是该项制度推进并不顺利。本文试从交易成本理论视角,分析当前新农合制度存在较高的交易成本导致制度创新不足。在此基础上,本文提出要使新农合制度可持续发展,政府必须从制度完善和机制创新两个方面降低交易成本,以提高新农合制度绩效。

经济学的二重性和在政策分析中的角色

经济学具有二重性,即兼具科学性质和人文性质.作为科学的经济学只涉及解释手段的选择,不考虑目的的选择问题.这是因为:手段的效果可以通过事实经验地证明,而目的包含价值观和伦理因素,无法转换为纯粹经验的描述.虽然不符合实证原则,但是作为人文的经济学是作为科学的经济学的前提,作为人文的经济学讨论目的的选择.在目的选择的过程中,伦理、价值判断、政治哲学等因素起着决定性的作用.社会实现稳定和谐的最终基础是道义与共识.     

Cost-utility of exenatide once weekly compared with insulin glargine in patients with type 2 diabetes in the UK

Abstract

Objective:

To compare the cost-utility of exenatide once weekly (EQW) and insulin glargine in patients with type 2 diabetes in the United Kingdom (UK).

Research design and methods:

The IMS CORE Diabetes Model was used to project clinical and economic outcomes for patients with type 2 diabetes treated with EQW or insulin glargine. Treatment effects and patient baseline characteristics (mean age: 58 years, mean glycohaemoglobin: 8.3%) were taken from the DURATION-3 study. Unit costs and health state utility values were derived from published sources. As the price of EQW is not yet known, the prices of two currently available glucagon-like peptide-1 products were used as benchmarks. To reflect diabetes progression, patients started on EQW switched to insulin glargine after 5 years. The analysis was conducted from the perspective of the UK National Health Service over a time horizon of 50 years with costs and outcomes discounted at 3.5%. Sensitivity analyses explored the impact of changes in input data and assumptions and investigated the cost utility of EQW in specific body mass index (BMI) subgroups.

Main outcome measures:

Incremental cost-effectiveness ratio (ICER) for EQW compared with insulin glargine.

Results:

At a price equivalent to liraglutide 1.2?mg, EQW was more effective and more costly than insulin glargine, with a base case ICER of £10,597 per quality-adjusted life-year (QALY) gained. EQW was associated with an increased time to development of any diabetes-related complication of 0.21 years, compared with insulin glargine. Three BMI subgroups investigated (<30, 30–35 and >35?kg/m²) reported ICERs for EQW compared with insulin glargine ranging from £9425 to £12,956 per QALY gained.

Conclusions:

At the prices investigated, the cost per QALY gained for EQW when compared with insulin glargine in type 2 diabetes in the UK setting, was within the range normally considered cost effective by NICE. Cost effectiveness in practice will depend on the final price of EQW and the extent to which benefits observed in short-term randomised trials are replicated in long-term use.     

Program Evaluation and Review Technique (PERT) in Construction Schedule Risk Assessment

Construction project scheduling is one of the most critical factors for project success measurement.Not only for the project planning but for construction process management,the scheduling is the basic tool for communication between the owner and the project manager.By developing the schedule before the project starts,the owner knows in advance that the expected timeline of the project.By preparing construction process scheduling,the owner and general contractor can better manage the subcontractors,sub-trades progress,materials storage and deliveries,labors schedule and equipment set up which will eventually save time,money and hassle.Basically,Critical Path Method(CPM) is commonly used in the construction industry.CPM is a deterministic method that assumes that through the network,there is at least one path that determines the project duration and that the path is the critical path.CPM does not consider the uncertainty in the activities;rather it assumes that each activity can be finished in the given situation.Program Evaluation and Review Technique(PERT) is a stochastic technique which is based on the assumption that the duration of a single activity can be described by a probability density function.PERT takes into account the uncertainty during the construction process and has been created out of the need to plan,schedule and control complex projects with many uncertainties.The PERT approach is stated in some books and papers,but there is no deep investigation on the application in the schedule risk assessment.This paper investigates the PERT work process and takes a valuable try on the construction schedule risk assessment by using case studies.The utilization in the estimate the construction liquidated damage with the uncertainties is performed,which also can be used in the insurance company to calculate the insurance premium.     

Wage and employment effects of a wage norm

Most transition countries used tax‐supported wage norms in the early 1990s, as a part of their market liberalization programmes. This article analyses how a firm‐level tax (or subsidy) on deviations from a pre‐set wage norm may promote employment by rotating the labour demand curve perceived by the workers’ union around the value of the norm. We derive the conditions under which it yields a positive employment effect. We test the effect of the norm on the wages on a sample of Polish firms in 1990 and 1991. The data support the role of the wage norm on the position of the perceived labour demand curve and the role of the tax rate on its slope.
