Consumption tax revenue and personal income tax: analytical elasticities under non-standard tax structures

This article models the elasticity of consumption taxation faced with changes in disposable income. Its calculation makes clear the importance of the design of the personal income tax and of the changes caused to the consumption of taxpayers. The modelling is performed for both individual taxpayers and the population as a whole.     

The satisfaction of university students in Spain: differences by field of study

This article analyses the factors associated with student satisfaction in a sample of undergraduate students from the University of Zaragoza (Spain). In addition to considering socio-demographic characteristics, we also examine factors related to expectations and motivations. Using data from a survey carried out during the academic year 2011/12, we show that the level of satisfaction of the students varies according to their field of study, finding that students in Engineering and Science are comparatively less satisfied than those in other disciplines. Also, expectations about whether having a university degree will be enough to obtain a job are associated with their level of satisfaction. Moreover, alcohol consumption is positively associated with their level of satisfaction. Analysing the correlates of student satisfaction is important to understand student retention and persistence.     

上海A、B股市场收益率波动性对比研究及预测

运用GARCH(1,1)-M模型对样本期内上海A、B股市场收益率波动性进行了对比研究及预测。结果显示:上证A、B股指数收益率序列均存在"ARCH/GARCH现象";上海A、B股市场中,期望收益与期望风险正向变动;上海A股市场记忆期长于B股市场;长期中,上海B股市场预期收益将超过A股市场。进一步结合基本面情况可知,上海B股市场具有相对较高的长线投资价值。     

协同创新的风险分摊与利益分配问题研究

协同创新利益分配问题是保持协同创新关系持续稳定发展的关键。综观国内外对利益分配的研究多是在不考虑协同各方所承担的风险基础上进行的,这是当今研究的一个空白点。首次提出投石效应的概念,并针对此问题对"Shapley值"进行修正,在此基础上提出新的利益分配方法,实例分析表明此方法克服了Shapley值法的不足,使利益分配的结果更具合理性和可行性。     

Distribution of correlation coefficient under mixture normal model

The present paper obtains the nonnull distribution of the product moment correlation coefficient r when sample is drawn from a mixture of two bivariate Gaussian distributions. The moments of 1−r ² have been used to derive the nonnull density of r. Received September 2000     

从生命周期浅谈高新技术企业融资策略

高新技术产业化的瓶颈是高新技术企业的融资困难现象,这也是全球高新技术企业普遍存在的问题。由于高新技术企业在其生命周期的不同发展阶段的财务状况、面临的风险以及资金需求特点是不相同的,从而决定了解决企业资金来源的融资渠道也必然不尽相同。本文将根据高新技术企业不同的成长阶段及其风险规律,动态地探讨了高新技术企业的融资策略。     

Fungibility and the flypaper effect of project aid: Micro-evidence for Vietnam

While most economists assume that aid is fungible, most aid donors behave as if it is not. Recipient government responses to development project aid are studied in the context of a specific World Bank-financed project. We estimate the impact of a rural road rehabilitation project in Vietnam on the kilometers of roads actually rehabilitated and built. Using local-level survey data collected for this purpose, we test whether the evidence supports the standard economic argument that there will be little or no impact on rural roads rehabilitated, given fungibility. Instead of full fungibility, we find evidence for a “flypaper effect”. Although impacts on rehabilitated road kilometers were less than intended, more roads were built in project areas. Our results suggest that there was fungibility within the sector, but that aid largely stuck to that sector.     

The cost of strikes in the Spanish mining sector: modelling an undesirable input with a distance function

In some contexts, firms have to deal with certain elements or factors that affect the production outcome but which are non-market in nature and therefore do not have a price. In this paper we propose a new use of a production economics tool, the input distance function, to empirically measure the effects of these factors. Although we suggest a general use of this methodology, it has been developed in the context of measuring the effects of labor disputes in a particular declining industry, that of Spanish coal mining. We have estimated an equation system comprising an input distance function and cost share equations to calculate the cost generated by strikes.
