政府责任视角商业保险参与新农合的文献综述

无论是从西方经济学的公共品和市场失灵视角,还是从我国农村合作医疗制度变迁过程来看,明确农村医疗保障政府责任的主要地位,都十分必要。通过对政府责任必要性和国际上农村医疗保障模式比较研究发现,保险业参与“新农合”的运作模式应该是我国农村医保制度的最优选择,必须明确政府部门与保险公司在“新农合”中的关系,强化政府在法制建设、制度设计、宣传引导、合理监督等方面的主导作用,充分利用商业保险的经营管理经验和技术水平,降低制度运行成本。     

我国外汇储备变动对通货膨胀的影响:2006.1-2012.12

使用2006年1月至2012年12月的月度数据研究我国外汇储备变动对我国通货膨胀的影响,运用VAR模型分析得出外汇储备变动对我国物价水平的直接影响很小,但是外汇储备变动可以通过改变货币供应量的变动对我国的物价水平产生间接影响。实证分析的结果表明：从长期来看,外汇储备变动1％将会引起货币供应量变动0．003％。货币供应量变动1％将会引起消费者价格指数变动0．009％。从实证分析的结果中可以看出,我国外汇储备的变动会对通货膨胀产生一定的影响,因此,中央银行在使用货币政策等手段冲销时要考虑其可能带来的负面影响并加以应对。     

中国创意服务贸易国际竞争力比较研究——基于TC指数和相对(技术)复杂度指数

在分析中国创意服务贸易特征的基础上,运用贸易竞争力(TC)指数和相对(技术)复杂度指数,采用UNCTAD发布的最新统计数据,对中国以及世界其他五个国家的创意服务贸易的国际竞争力进行了比较研究。结果显示:我国创意服务贸易已具备一定的国际竞争力,在世界创意服务贸易的地位也不断提升,但是各分项发展很不平衡。因此,要加强对进出口市场的了解,优化出口结构,提高创意服务进口的技术水平,同时注重创意服务高端人才的培养与引进。     

中国海洋强国、强省（市）指数测算研究

借鉴国际国内发展指数和经济强国指数的构建原理和方法,结合我国海洋事业发展现状,运用主成分分析和独立性分析等方法,设计构建海洋强国指数测算指标体系,建立算术加权合成指数测算模型。对我国沿海地区2007—2011年间海洋经济发展指数、海洋科技发展指数、海洋资源存量指数、海洋可持续发展指数、海洋产业竞争力指数等个体指数进行测算,并合成计算得到海洋强省（市）指数,以此为基础对我国2002—2011年的海洋强国指数进行综合测算,根据指数变化趋势图对我国海洋经济、科技、可持续以及产业发展情况进行了动态分析,探究了海洋强国、强省（市）指数变化的内在动因。     

1:10000比例尺土地利用景观指数的粒度效应分析

研究目的:基于鹤峰县1:10000土地利用数据,对土地利用数据的景观指数类型及景观水平的粒度效应进行分析。研究方法:GIS和景观格局分析软件应用。研究结果:在类型水平上,景观指数的粒度效应较明显,随粒度的变粗,景观指数可归为单调下降、不规则变化和基本无变化3类;粒度响应最敏感的景观指数为斑块密度;裸地和水田是对粒度响应最敏感的两种土地覆盖类型。在景观水平上,除斑块密度外,其他景观指数粒度效应不明显,斑块密度和面积加权平均分维数的粒度响应最强烈,丰富度指数则最弱。研究结论:粒度效应与所选粒度的变化范围、数据聚合方式、分析景观类型的多少、比例尺的不同都有很大的关系,更深层次的研究需要考虑更加全面。     

El Niño,La Niña,and world coffee price dynamics

Coffee is produced in equatorial and subequatorial regions of the world, which are also most affected by El Niño Southern Oscillation (ENSO). ENSO events have a tendency to amplify weather conditions such as droughts or excess precipitation in the affected regions, resulting in production shortage or excess supply, subsequently impacting agricultural commodity prices. In this research we assess effects of ENSO events on world coffee price dynamics using the monthly data between March 1989 and December 2010. We employ smooth transition autoregression framework to examine nonlinear dynamics of ENSO and coffee prices, and illustrate the results of this research using generalized impulse‐response functions. We find that ENSO events indeed have short‐term impacts on coffee prices. The research findings are of interest to coffee producers and intermediaries in the coffee markets as well as researchers in the fields of environmental and development economics.     

Investigating the performance of different estimation techniques for crop yield data analysis in crop insurance applications

We investigate the performance of the ordinary least squares (OLS)‐, M‐, MM‐, and the Theil–Sen (TS)‐estimator for crop yield data analysis in crop insurance applications using Monte Carlo simulations. More specifically, the performance is assessed with respect to trend estimation, prediction of future yield levels, and the estimation of expected indemnity payments. In agreement with earlier findings, other estimators are found to be superior to OLS in simple regression problems if yield distributions are outlier contaminated and heteroscedastic. While this conclusion is also valid for subsequent applications such as yield prediction and the estimation of expected indemnity payments, the difference between the considered estimators becomes less distinct. For these applications, we find particularly the M‐estimator to be a good compromise between high‐breakdown (very robust) estimators and the very efficient OLS‐estimator. Because no regression technique dominates all others in all applications and scenarios for error term distributions, our results underline that the choice of the estimation technique should be dependent on the purpose of the crop yield data analysis. However, alternative estimators such as M‐, MM‐, and TS‐estimator can reduce (and bound) the risk of unreliable or inefficient crop yield data analysis in crop insurance applications.     

Using Project-Based Learning （PBL） in Management Accounting Course： Lesson and Reflection From Entrepreneurship Education

One of the main issues in entrepreneurship education is integrating core course to entrepreneurship course. Many educators fail to integrate core course and entrepreneurial education. The purpose of this study is to investigate whether the integration of management accounting course in entrepreneurship course will accomplish the objective of entrepreneurship education. This study is derived from the experience of entrepreneurial project course at Management Department of Ciputra University, Surabaya. This study uses an explorative approach to investigate the implementation of project-based learning （PBL） in management accounting course. The result shows variation of output. There are about 91% business can be implemented by business groups and about 33% target achieved. Several management accounting techniques are used in this study, such as balanced score card （BSC）, activity-based costing （ABC）, activity-based management （ABM）, cost-volume-profit （CVP） analysis, and tactical decision making. This study found that by using management accounting techniques, student can run the business well especially when they have to make decision. This study strengthens the role of management accounting in business practices, and furthermore, this study proves that management accounting is beneficial for entrepreneurs who are still in the start-up business stage.
