开放式基金投资风格浅析

近年来，开放式基金在我国发展极为迅速，在数量不断增加的同时，呈现出的风格日趋多样化。面对种类繁多的开放式基金，投资者很难分清哪种投资风格更适合自己的风险偏好，因而投资风格逐渐成为基金最重要的识别系统之一。本文首先介绍了开放式基金的定义，其次，根据财务指标对开放式基金的投资风格进行分类并描述不同类型基金的特点。最后分析了基金最终风格出现趋同的原因。     

基于协整分析的东北区域产业结构优化与金融支持关系研究

基于1978—2003年的统计数据,采用协整关系检验法和格兰杰(Granger)因果检验法对东北地区金融发展与产业结构优化之间的关系进行了实证检验。分析结果表明东北区域产业结构优化与金融发展之间存在长期动态均衡关系及单向因果关系,即金融发展对东北区域产业结构优化具有支持作用,从而为政府经济决策提供了政策依据。     

国库集中支付操作风险产生机理的博弈分析

国库集中支付操作风险是指国库资金支付过程中出现违规操作行为的可能性。国库集中支付制度框架下财政资金支付活动是财政部门、预算单位、代理银行和人民银行共同参与的博弈过程。本文运用博弈理论首先分析国库集中支付操作风险产生的内在机理，然后剖析国库集中支付操作风险产生的外在博弈条件，最后从优化博弈条件出发，提出建立健全监督激励机制以防范国库集中支付操作风险的建议。     

Domestic Support and Border Measures for Processed Horticultural Products

In horticultural markets, trade barriers often apply to the processed products whereas domestic support applies to farm-produced raw commodities. Here we assess the effects of such trade barriers and domestic support by simulating the effects of policy reform on global processing tomato markets, which are faced with modest processed product tariffs and high domestic support in the European Union (EU). Both protection and EU subsidy drive down world welfare, but we find that reducing import tariffs for tomato products would yield greater effects on markets and larger welfare impacts outside Europe than would reductions in EU domestic support.

Hypothesis tests using data envelopment analysis

A substantial body of recent work has opened the way to exploring the statistical properties of DEA estimators of production frontiers and related efficiency measures. The purpose of this paper is to survey several possibilities that have been pursued, and to present them in a unified framework. These include the development of statistics to test hypotheses about the characteristics of the production frontier, such as returns to scale, input substitutability, and model specification, and also about variation in efficiencies relative to the production frontier.

Regional job-turnover and industrial policy. a note on a potential time pattern of regional industrial policies and their job effects - the case of the german city-state of bremen

Many regions have experienced long-run economic fluctuations generated by the life cycles of their dominant industrial clusters. During the downswings in the 1970s and 1980s, proactive structural policies were typically launched in German regions to combat job losses in their core clusters and to create new jobs in new industries. With respect to the German State of Bremen, this paper provides empirical evidence of: (1) a long-run regional downswing; (2) the potential job effects of proactive regional industrial policy programmes in terms of increasing regional employment, by safeguarding jobs in the regional core industries and creating new jobs in new growth industries; and (3) a time pattern in the job effects, which are related to the different generations of programmes.
