当前我国应尽快推出开放式基金

世界上绝大多数国家的基金业都是以开放式基金为主,而我国目前的证券投资基金全部都是封闭式基金,我国已初步具备了设立开放式基金的条件,设立开放式基金,既是迎接“入世”要求,也是我国基金业的发展方向,我国在开放式基金设立初期,既要吸取国外的成功经验,又要结合我国的实际情况,让开放式基金顺利推出并闪亮登场。     

Dynamic programming for valuing American options under a variance-gamma process

Lévy processes provide a solution to overcome the shortcomings of the lognormal hypothesis. A growing literature proposes the use of pure-jump Lévy processes, such as the variance-gamma (VG) model. In this setting, explicit solutions for derivative prices are unavailable, for instance, for the valuation of American options. We propose a dynamic programming approach coupled with finite elements for valuing American-style options under an extended VG model. Our numerical experiments confirm the convergence and show the efficiency of the proposed methodology. We also conduct a numerical investigation that focuses on American options on S&P 500 futures contracts.     

Planning and managing primary care services: lessons from the NHS in England

High-quality primary care services are an essential part of a successful health service. However, the planning and management of such services is complex. Using evidence from a study of recent extensive changes in the English NHS, the authors highlight the need for local service oversight by managers who understand local conditions and needs. The recent English experience supports an incremental policy adjustment approach, rather than wholesale organizational change.     

Mad about Austerity? The Effect of Fiscal Consolidation on Public Opinion

We explore the impact of fiscal austerity on three different dimensions of public opinion in 26 European Union countries (consumer confidence, attitude toward national authorities, and European institutions) on annual data between 1997 and 2017. Our main finding is that the independent effect of a tighter fiscal stance on public opinion is not large and, when present, seems to closely follow the impact of fiscal austerity on economic activity. Our results therefore are inconsistent with the view that fiscal austerity necessarily implies a negative effect on public opinion and a decline in popularity of national and European institutions.     

中药材初加工废水处理工程设计与运行

针对亳州某产业园中白芍初加工废水,包括清洗废水和蒸煮脱皮废水,其中白芍清洗废水处理采用“旋流沉砂器+平流沉淀池”工艺,白芍蒸煮脱皮废水处理采用预处理和“UASB+A/O+混凝沉淀(保障工艺)”工艺,并考察其运行效果。结果表明:清洗废水经处理后出水水质可以达到清洗回用标准,使废水可循环再利用;蒸煮脱皮废水处理后达标排放,出水水质满足《中药类制药工业水污染排放标准》(GB21906-2008)中污染物最高允许排放浓度的一级标准。该废水处理工程运行稳定、出水达标,可为同类工程设计提供参考。

严元照生卒年考辨

严元照乃清代乾嘉时期著名学者,但长期以来,学界对于其生年、卒年一直有不同的说法。通过考察相关文献,可断定严元照生于乾隆三十八年(1773年),卒于嘉庆二十二年(1817年),寿四十五。     

脱贫攻坚背景下提升农村基层党组织组织力研究

我国脱贫攻坚工作错综复杂,任务繁重,在全面脱贫攻坚过程中,对农村基层党组织的组织力提出了新的要求。不少农村基层党组织的组织力还存在党员干部思想文化素质偏低、党组织领导核心作用被弱化、流动党员队伍教育管理困难、部分党组织从严治党不力等诸多问题。基于以上分析,本研究从增强基层组织核心力、提升振兴发展推动力、激发贫困群众内生动力、坚强基层组织保障力等方面入手,提出提升农村基层党组织组织力助推脱贫攻坚的有效路径。     

Fiscal Consolidation and the Public Sector Balance Sheet in South Africa

Between 1994 and 2008 the South African government reduced its debt/GDP ratio from almost 50% to 27%. Unfortunately this reduction was accompanied by a significant decrease in government's fixed capital/GDP ratio from 90% to 55% – fiscal sustainability might have been restored, but government's balance sheet did not improve. A similar story can be told for State Owned Enterprises. Since the Great Recession the fiscal situation worsened markedly – the public debt ratio again approaches 50%. To restore fiscal sustainability this article suggests that the government faces two options: (1) to create room for future countercyclical policy, the government must cut current expenditure and reduce the public debt/GDP ratio to its pre‐crisis level, or (2) substitute much‐needed infrastructure capital expenditure for current expenditure while stabilising the debt/GDP ratio at its post‐crisis level. Given that the much lower fixed capital/GDP ratio inhibits economic growth, the latter option might be more sensible.
