"Quicker and sicker" under Medicare's prospective payment system for hospitals: new evidence on an old issue from a national longitudinal survey

Medicare's prospective payment system for hospitals (PPS), introduced in the USA in 1983, replaced cost reimbursement with a system of fixed rates which created incentives for hospitals to control costs. Previous studies found that elderly patients were discharged from hospital "quicker and sicker" under PPS and concluded that families were coping at home. We analyse a national longitudinal survey, the first National Health and Nutrition Examination Survey and its Epidemiologic Followup Study, which includes data on more outcomes over a longer period than earlier studies. We find that the rate of admission to nursing homes from the community in the first weeks after a hospital discharge more than tripled under PPS, suggesting that families were not always able to cope. As another response to sicker patients, discharges directly to nursing homes from hospitals, which jumped initially under PPS, may have risen further when payment rates were tightened in the early 1990s. Hospital readmissions fell after the first few years. Our findings are strengthened by the fact that we control for patients' health using health information collected independently of hospital admission.     

我国二线城市交通拥堵的症结与消弭策略——以青岛为例

目前,交通拥堵已呈一线城市向二线城市蔓延的趋势,作为二线城市的青岛,很难一下子从轨道交通等硬件设施建设上改变现状。为此,文章提出了统筹兼顾,综合治理的对策:一是优化城市结构,合理规划城市交通网络;二是推动城市道路建设,完善城市交通基础设施;三是改善道路交通模式,优先发展城市公共交通;四是提升综合管理能力,理顺城市交通体制;五是应用交通新科技,建立一体化城市交通信息系统;六是提高停车泊位供应,推动城市停车设施供需平衡。

福建森林保险案例研究

回顾了20世纪80年代以来福建省森林保险的发展历史,并以南平和三明市为例,从森林保险的规模、品种、具体做法以及配套政策等方面做了案例研究。通过案例分析,对福建省森林保险发展情况进行了基本判断:全省对森林保险的群体需求有差异,森林保险业务供给有限,林业部门和保险公司诉求不同,需要加强理解和沟通。     

中国北方大规模生猪养殖技术效率研究

[目的]通过对我国北方地区大规模生猪养殖技术效率进行测度,以期发现影响其技术效率增长的主要因素,为我国现阶段生猪养殖业战略性区划调整"南猪北进"工作提供实践指导和理论支持。[方法]根据随机前沿分析方法 (SFA)基本原理,运用对数型柯布—道格拉斯生产函数及我国北方大规模生猪养殖数据构建中国北方大规模生猪养殖随机前沿分析模型,对我国北方大规模生猪养殖技术效率进行测度并据此提出相关建议。[结果]北方地区大规模生猪养殖技术效率值纵向上来看整体在不断下降,而从地域上来看内蒙古自治区和东北地区技术效率值较高,北京与西北地区技术效率值较低。[结论]内蒙古自治区与东北地区适宜作为大规模生猪养殖承载地,与国家政策具有一致性;华北地区与西北地区大规模生猪养殖技术效率测度值较低,存在较大改进空间;针对该现状提出构建经济效益与环境保护并重的规模生态生猪养殖体系。     

物流成本:价格上涨的重要推手

物流成本是物流活动中所消耗的物化劳动和活劳动的货币表现,作为商品价值的重要组成部分,其上升必然推高商品价格,成为商品价格上涨的重要推手。它的上升主要会通过运输费用、经管费用、税费和制度性成本等路径推动商品价格上涨。要保持市场价格的基本稳定,必须通过改革公路收费、改进物流管理、培育物流企业、优化物流模式等措施,多管齐下遏制物流成本上升。     

Mutual fund flows and window-dressing

We use a sequential game to analyze an agency problem in the mutual fund industry where a representative fund manager considers window-dressing his portfolio holdings for the purpose of attracting fund flows from a representative investor. The manager is motivated to window-dress to improve the investor's perception of managerial skill which may positively affect fund flows in the next period. However, the investor may suspect window-dressing and thus downgrade perceived managerial skill. The model supports a Bayesian Nash equilibrium where the manager window-dresses only when receiving a low return in the first period and the investor withdraws funds only when observing low returns in both periods. Consequently, we show that window-dressing is a rational behavior even when fund outflows may result.

城市生态学在福州市城市环境规划中的应用

城市生态学是生态学的重要分支,是研究城市居民与城市环境相互关系的科学.城市生态学的发展使人类对人居环境和可持续观念有了深入的认识,建立生态城市已经成为本世纪城市发展的明确目标.城市环境规划是城市建设和发展的"龙头",是城市健康发展、科学管理的重要依据,也是城市走可持续发展道路的重要环节.城市环境规划作为宏观指导和协调部门利益、优化城市土地资源配置、合理组织城市空间环境的重要战略部署,必须具备生态思想.
