征税成本领先性假设与中国税务组织结构优化——兼析中国国税、地税机构是否存在合并趋势 总被引:9,自引:0,他引:9
本文从征税成本领先性假设出发探讨了中国税务组织结构的优化问题 ,并分析了社会各界广泛关注的中国国税、地税机构是否存在合并趋势的问题。本文在对中国现行税务组织机构运行绩效考察的基础上 ,发现中国征税成本曲线呈抛物线状 ,表明中国征税成本正呈递减趋势。以此为出发点 ,本文详细论证了中国国税、地税机构不存在合并的趋势 ,相反 ,分设更为彻底却是今后的发展趋势 ,得出了与一般看法不同的结论 ,并对优化中国税务组织结构提出了政策建议 相似文献

SummaryMany patients with epilepsy continue to have partial seizures requiring add-on antiepileptic drugs (AEDs). Zonisamide, a broad-spectrum AED, has recently entered the European market and must be compared with the current standard of care. The objective of this study was to determine the cost effectiveness of zonisamide as treatment for adults with uncontrolled partial epilepsy in Scotland. A Markov decision model was developed from the perspective of the Scottish National Health Service. Outcome measures included quality-adjusted life-years (QALYs) and costs in GBP.Patients treated with zonisamide had a 15-year incremental cost of £20 and 0.026 additional QALYs compared with patients treated with levetiracetam. These modest differences result in an incremental cost-effectiveness ratio for zonisamide of £761/QALY.We conclude that zonisamide is a cost-effective treatment for adult patients with refractory partial epilepsy being treated according to Scottish treatment patterns and costs, assuming a willingness to pay of £20,000/QALY. 相似文献

This article presents an intertemporal model of production with multiple inputs to investigate substitution opportunities facing firms over time. The firm’s intertemporal profit maximization problem is characterized with the familiar cost function, and various intertemporal substitution elasticities are delineated for output supply and input demand. The absence of intertemporal substitution in production can imply production smoothing, and allowance for intertemporal substitution in labour demand reinforces the prediction of the real business cycle model. For aggregate US manufacturing, we find substantial substitution in output supply and labour demand over time due to intertemporal changes in output price and wage rates. 相似文献

This study assesses the foreign debt policy in Egypt and contrasts it versus the optimal policy during the period 1985–2008. It also presents a forecast of the optimal debt during the period 2009–2014. The optimal debt policy was derived using an open economy model for Egypt. The uncertainties in the model stem from the uncertainties in the interest or debt service payments and the uncertainties in the rate of return on investments. The stochastic control approach was used to find the optimal debt policy. It was found that Egypt could borrow externally as long as the trend in the rate of return on investments exceeds the trend in the real interest rate or the trend in the rate of the debt service payments. The analysis finds that Egypt's foreign debt was higher than the optimal level before 1997. After 1997, foreign debt seems to converge to the optimal level. However, Egypt's foreign debt is still below its optimal level which results in an opportunity cost for the economy to grow, otherwise, GDP could have recorded a favorable increase. 相似文献

We investigate the effects of the 2008 New Zealand (NZ)–China free trade agreement (FTA) on exports from NZ to China, and real GDP per capita in NZ using the synthetic control method to estimate the counterfactuals. NZ exports to China were more than 200% higher in 2014 than what they would have had the FTA never been signed. NZ's food and live animals exports to China were more than 180% higher in 2014 than the counterfactual. Our counterfactuals indicate a small but negative effect of the FTA on NZ's real GDP per capita between 2009 and 2012. 相似文献

Objectives: This study used a diagnosis-based risk adjustment model to estimate the annual costs of uninsured patients in Austin, Texas, and describe the prevalence and costs of their chronic conditions. The data were supplied by the Indigent Care Collaboration, a partnership of local safety-net hospitals and clinics.Methods: This study used the Diagnostic Cost Groups prospective Medicaid All-Encounters model, which uses diagnoses, age and gender to assign relative risk scores to patients. The relative risk scores were multiplied by the per capita Texas Medicaid expenditure to obtain estimated annual costs. Chronic diseases were described in terms of prevalence and total estimated annual cost.Results: A total of 471,194 encounters were recorded for 163,729 patients meeting the study inclusion criteria between the 1st March 2004 and the 28th February 2005. The mean estimated patient yearly cost was US $1,307, and the total estimated yearly population cost was $228,909,529. The most common chronic conditions included hypertension, diabetes, depression, substance abuse, pregnancy, asthma, chronic obstructive pulmonary disease and congestive heart failure.Conclusions: This study demonstrates how the unknown costs associated with caring for indigent uninsured patients in a community can be estimated at Medicaid reimbursement rates using the Diagnostic Cost Group model on aggregated patient encounter data. 相似文献

SummaryThe objective was to assess the medicoeconomic impact of initial and subsequent treatments based on oral fludarabine, intravenous chemotherapy (mini-CHOP) and chlorambucil in chronic lymphocytic leukaemia.A Markov model has been defined to encompass the 18 strategies over a 3-year period after starting the first treatment. Costs of treatments, side effects and follow-up have been calculated by crossing data from published prospective trials, specific hospital databases and French resource-based relative value scales. When treatments were based on mini-CHOP, different possibilities offered for hospital care were taken into account.Probalistic sensitivity analysis was performed.Whatever the modality of hospital care for mini-CHOP, the strategies based on oral fludarabine as first-line treatment are not only more effective but are also cost effective and dominate other types of scenarios.Fludarabine given orally should be preferred to mini-CHOP or chlorambucil as a first-line treatment for patients with chronic lymphocytic leukaemia. 相似文献

Factors affecting subjective well-being and their gross effect measurement have been widely studied. However, how people derive utility from these factors has not been fully explored. This article provides a way to decompose the gross effect of major determinants on life satisfaction into direct and indirect effects and make inference for the latter. Because the indirect effect is nonlinear in parameters associated with different models in an equation system, it creates a problem in estimating the standard error. Besides, the categorical nature in survey data further introduces bias to the covariance estimation even asymptotically. To address these issues without knowing the form of heteroskedasticity under the null hypothesis, we propose to extend the wild bootstrap procedure in this particular context. Its robustness against various data properties is validated via several simulation experiments. Using three recent waves of World Values Survey, we find that the relative importance of life control has significantly increased recently, and endowing citizens with the right to enjoy their freedoms and liberties is a more effective policy in raising life satisfaction than promoting national income. 相似文献
