A cointegrating approach is undertaken in this study to determine if there is a long-run equilibrium relationship between budget deficits and long-term interest rates for the United States and nine European countries. The cointegration approach consists of conducting cointegration tests and then testing several hypothesized values for the deficit and price expectations variables. The cointegration results suggest the existence of several significant cointegrating vectors for each of the ten countries, which would seem to appeal to the view of budget deficits having a positive impact on long-term interest rates. The hypothesized values for the deficit and price expectations variables are found to be too strict since the hypotheses are rejected in every case but one.  相似文献

Objectives:

A recent phase III trial showed that patients with advanced non-small cell lung cancer (NSCLC) whose tumors harbor specific EGFR mutations significantly benefit from first-line treatment with erlotinib compared to chemotherapy. This study sought to estimate the budget impact if coverage for EGFR testing and erlotinib as first-line therapy were provided in a hypothetical 500,000-member managed care plan.

Methods:

The budget impact model was developed from a US health plan perspective to evaluate administration of the EGFR test and treatment with erlotinib for EGFR-positive patients, compared to non-targeted treatment with chemotherapy. The eligible patient population was estimated from age-stratified SEER incidence data. Clinical data were derived from key randomized controlled trials. Costs related to drug, administration, and adverse events were included. Sensitivity analyses were conducted to assess uncertainty.

Results:

In a plan of 500,000 members, it was estimated there would be 91 newly diagnosed advanced NSCLC patients annually; 11 are expected to be EGFR-positive. Based on the testing and treatment assumptions, it was estimated that 3 patients in Scenario 1 and 6 patients in Scenario 2 receive erlotinib. Overall health plan expenditures would increase by $0.013 per member per month (PMPM). This increase is largely attributable to erlotinib drug costs, in part due to lengthened progression-free survival and treatment periods experienced in erlotinib-treated patients. EGFR testing contributes slightly, whereas adverse event costs mitigate the budget impact. The budget impact did not exceed $0.019 PMPM in sensitivity analyses.

Conclusions:

Coverage for targeted first-line erlotinib therapy in NSCLC likely results in a small budget impact for US health plans. The estimated impact may vary by plan, or if second-line or maintenance therapy, dose changes/interruptions, or impact on patients’ quality-of-life were included.  相似文献

ABSTRACT

In neoliberalism, human tissue has been targeted as a source for extracting surplus value. Commercial attention on ethnic and racial minorities has resulted in products and services specifically developed for them. Here, we focus on this by exploring two empirical examples: US pharmaceutical clinical trials and UK stem cell transplantation. Both use racial taxonomies to discern biological difference and draw conclusions about the economic potential of people’s genetic constitutions. They do so by appealing to racialised minorities’ sense of responsibility towards ‘their’ communities, both buttressing the conflation of social and biological registers of human variation and demonstrating neoliberalism’s mobilisation of discourses of community. However, while the inclusion of racialised minorities is hoped to bring economic benefits, it also aims to address healthcare inequalities. Drawing on Science and Technology Studies, we argue that in our examples, economic, social and cultural values cannot be disentangled. This compels us to complement narratives of the commodification of racialised difference in neoliberal (consumer) culture, and focus on the intersections between different economic and ethical values. Ultimately we find that whilst work is being done to ameliorate racial inequities, broader socio-economic and political inequalities minority communities face go unaddressed, likely precluding the realisation of health equality.  相似文献

Objective: This study is to evaluate the costs, clinical efficacy, and social benefits of a patient assistance program (PAP) implemented by the China Primary Healthcare Foundation for the use of pemetrexed as a first-line non-squamous non-small cell lung cancer (NSCLC) maintenance therapy in China.

Methods: A survival analysis was conducted on the clinical data of 1,366 patients who participated in the PAP. The progression-free survival (PFS) and median maintenance treatment cycle of pemetrexed were analyzed. A 36-month Markov model from a payer’s perspective was constructed to analyze the cost and effectiveness associated with the PAP for pemetrexed. The inputs of the model were sourced from the PAP clinical database and published literature. The study estimated the incremental quality adjusted life-years (QALYs) (pemetrexed plus best supportive care [BSC] vs BSC only), the cost saving of the PAP, the impact on the percentage of catastrophic health expenditures (CHE), and poverty headcount ratio (HCR).

Results: The median of PFS and maintenance treatment cycles were 187 days and five cycles (total nine cycles, which included four cycles of induction therapy), respectively. The pemetrexed plus BSC treatment with PAP resulted in an additional 0.12 QALYs over BSC only. The total cost was $48,034.46 and $96,191.57 for the patients who had or had not joined the PAP in 3 years, respectively. Compared to the patients without PAP, the percentage of CHE and HCR with PAP was reduced from 98.39% to 19.91% and 66.98% to 4.89%, respectively, indicating that the PAP substantially decreased the number of patients who had CHE and fallen into poverty.

Conclusion: The study concluded that the pemetrexed PAP generated noticeable clinical and economic benefits to society and to patients. The program also increased patients’ compliance with chemotherapy by allowing patients, for whom the pemetrexed treatment was unaffordable, to continue to receive it.  相似文献

This paper investigates the determinants of disparities in coverage by cell telephone systems in Sub-Saharan Africa. It uses a spatially disaggregated probit for over 990,000 grid cells with adjustments for spatial autocorrelation. Determinants include potential market size (population); cost factors related to accessibility (elevation, slope, distance from a main road, and distance from the nearest large city); and competition policy. Estimates indicate significant results for the supply–demand variables, and very strong results for the competition policy index.Simulations suggest that a generalized improvement in competition policy could lead to huge improvements in cell phone area coverage, and to an overall coverage increase of nearly 100%.  相似文献

质子交换膜燃料电池(proton exchange membrane fuel cell, PEMFC)输出性能的影响是多方面的,极化曲线仅能反映燃料电池稳态外输出特性,不能充分反映具体影响因素及规律,因此需研究其内部物理参数的动态变化。通过建立电堆内阻和交流阻抗特性模型,利用电化学交流阻抗谱(electrochemical impedance spectroscopy, EIS)分析不同温度和湿度下燃料电池的内阻动态特性。结果表明,在333~353 K温度范围内,随着温度的增加,燃料电池的内阻减小;当温度不变时,相对湿度的增加能减小电堆内阻,燃料电池输出性能增强。最后,基于15kW燃料电池测试平台进行性能试验,验证了燃料电池动态特性分析的正确性,为进一步优化PEMFC输出性能提供理论支持。  相似文献

为了实现碳中和目标,通过VAR模型分析能源消费与废气排放量关系,进而提出改变能源生产消费方式的建议。基于山西省2007—2021年煤炭消费量、石油消费量、焦炭消费量和废气排放量数据,通过单位根检验、约翰逊协整检验、建立误差修正模型和向量自回归(VAR)模型,格兰杰因果检验,做出出脉冲响应图并进行方差分解,得出山西省煤炭消费量、石油消费量、焦炭消费量和废气排放量的长短期均衡关系和影响力度。研究表明,煤炭消费使废气排放量呈高排放状态,石油消费未曾大的影响废气排放,焦炭消费使废气排放量先升后降。研究提出山西省能源生产消费的节能减排路径,包括应用先进煤化工和煤电技术、开发石油生产消费低碳技术、促进新能源技术的普及和应用、开发能源互联网及绿色金融等新兴产业等。  相似文献
