土地征收争议解决机制之横向比较——以典型国家的立法为参照

英、美、法、德等国家的土地征收争议解决机制在基本理念和具体的制度安排方面存在许多共同的做法,但是,对于裁决模式、公共利益的认定模式、补偿数额以及补偿范围的确定等模式都在一定程度上存在着差异,造成这种差异的原因既有文化传统上的因素,也受各国具体国情所决定。

“十二五”期间陕西人身保险市场需求变化研究

＂十二五＂期间,陕西省经济的持续发展为陕西省人身保险市场的发展提供了有利契机。人身保险需求是度量人身保险市场发展状况的重要指标。文章以陕西省人身保险保费收入作为衡量人身保险市场需求的变量,参考保险密度和保险深度等指标,选取1990—2009年的相关数据,采用协整检验,利用自然对数模型对陕西省人身保险市场需求进行实证分析,并据此对＂十二五＂期间陕西省人身保险市场需求变化趋势进行预测,旨在为陕西省人身保险业规划提供理论依据。     

Economic evaluation of olmesartan/amlodipine fixed-dose combination for hypertension treatment in China

Abstract

Objectives: To evaluate the cost-effectiveness of olmesartan/amlodipine fixed-dose combination vs olmesartan and amlodipine free combination, amlodipine single drug, and valsartan/amlodipine fixed-dose combination in the treatment of hypertensive patients from payer perspective in China.

Methods: A Markov model was constructed, which included five health states of hypertensive patients who are aged 35–84?years at baseline and free of cardiovascular disease. Clinical data were obtained from a network meta-analysis. Epidemiology data, adverse events (AEs), cost, and utility data were obtained from the literature. The cost associated with AEs was estimated based on the cost of same symptoms of hypertensive patients in an electric medical record database. The model projected quality-adjusted life years (QALYs) gained, total costs per patient in a 20-year time horizon, and incremental cost-effectiveness ratios. Probability sensitivity analyses (PSA) and one-way sensitivity analyses were conducted for the main parameters to test the robustness of the model.

Results: Compared to olmesartan and amlodipine free combination, amlodipine, and valsartan/amlodipine fixed-dose combination, treatment with olmesartan/amlodipine fixed-dose combination led to fewer CVD events and deaths; resulted in an incremental cost of ¥?5,439 ($?791.36), ¥6,530 ($950.09), and ¥?1,019 ($?148.26) and gained additional QALYs of 0.052, 0.094, and 0.037 per patient, respectively. Compared with olmesartan and amlodipine free combination and valsartan/amlodipine fixed-dose combination, olmesartan/amlodipine fixed-dose combination was dominant. Compared with amlodipine alone, the incremental cost-effectiveness ratios were below the WHO recommended cost-effectiveness threshold, indicating the olmesartan/amlodipine fixed-dose combination was a cost-effective option for hypertensive patients in China. The 10-years’ time horizon scenario analysis showed similar results to the 20-years’ time horizon. Probabilistic sensitivity analysis and one-way sensitivity analyses showed the robustness of the model results.

Conclusions: Olmesartan/amlodipine fixed-dose combination confers better health outcomes and costs less compared with olmesartan and amlodipine free combination and valsartan/amlodipine fixed-dose combination, and is cost-effective compared to amlodipine for hypertension treatment in China.

从资本属性看劳资关系的平等性和公平性

中国经济转型时期资本在循环过程中的不公平、不平等问题,揭示了资本不可忽视的社会属性以及这种属性对劳资关系中平等性、公平性的影响。而"契约"作为连接资本与劳动力的重要环节,必然体现出二者之间的经济和社会关系,契约自身的不公平性和不平等性揭示出资本所蕴含的、其自身无法解决的社会与经济两方面的公平、平等和正义问题。因此,资本经济属性的实现并不会必然导致公平和平等,而无视资本的社会属性,经济越是发展,公平与平等程度越低。     

On the anticipation of IPO underpricing: Evidence from equity carve-outs

We investigate IPO market efficiency using a sample of equity carve-outs offered during the period of 1985–2005. Unlike IPOs examined in previous studies where trading during the pre-IPO book-building period does not exist and trading on the IPO date is rationed, in equity carve-outs, investors can trade in the non-rationed market for shares of the parent, which holds a significant fraction of the subsidiary. We find that the subsidiary's initial day return is significantly related to its parent's return over the book-building period, but unrelated to its parent's contemporaneous return. Neither the pre-IPO price revision of the subsidiary nor the return to the parent on the initial trading day can be predicted. While the portion of the subsidiary's initial return unpredictable from information available during the book-building period is significantly related to its parent's contemporaneous return, the predictable component of the initial return is not. We interpret these results as evidence consistent with market efficiency.
