A comparison of Ad valorem and per unit taxes in regulated monopolies

This paper compares the output and revenue effects in the rate-of-return regulated monopoly model. Both the ad valorem and the unit tax generally decrease the use of capital, and as such, reduce the output and raise the price. In addition, it is shown that Suits and Musgrave's conclusion of higher revenue of an ad valorem tax at a given output can apply to a regulated monopolist if the marginal product of labor under the ad valorem tax is greater than or equal to that under the unit tax. Similarly, their second conclusion, that for a given tax revenue an ad valorem tax has a larger output than a unit tax rate before the revenue-maximizing tax rate, can also apply to the regulated monopolist.     

产业国际竞争力研究综述(Ⅱ)

产业国际竞争力研究是当前经济领域的热点研究问题,国内外学者对其进行了大量研究,然而对其理论与分析模型的全面系统回顾却不多见.基于这种现状,全面回顾了产业国际竞争力的研究现状并详细评述了其分析模型,为今后的进一步研究奠定了基础.     

Hedonic models and air pollution: Twenty-five years and counting

This paper reports a meta analysis of how effectively hedonic property models have detected the influence of air pollution on housing prices. Probit estimates are reported describing how data, model specification, and local property market conditions in cities represented in thirty-seven studies influence the ability of hedonic models to uncover negative, statistically significant relationships between housing prices and air pollution measures.Partial support for this research was provided by the Russell Sage Foundation. Thanks are due David Cordray, Heidi Hartman, and Larry Hedges of the Foundation's Meta-Analysis Panel for constructive comments, to Ray Palmquist for suggestions and assistance in assembling the results from his studies, to Rick Freeman and Tom Tietenberg and two anonymous referees for comments on the research, and to Barbara Scott for constructive editing of earlier drafts of this paper.     

中国城市间流通网络及其层级结构——基于中国连锁企业百强店铺分布的网络分析

本文以网络的视角透析中国城市间的流通体系,选取中国连锁百强企业的店铺网络为样本,应用社会网络分析的测度方法,对中国城市间流通网络的整体属性及其层级结构进行了研究.研究发现:(1)联结全国主要城市的完整流通网络已初步形成,但网络密度不高,并且网络区域性特征明显,区域网络之间存在重叠,也存在结构洞.(2)中国城市间流通网络的不均衡性较强,层级结构明显,北京和上海是城市间流通网络的核心.(3)流通网络在空间分布上很不均衡,也呈现明显的层级结构,东部地区的网络密度明显高于中、西部地区,东部城市在网络层级中的位置较高,而网络结构洞主要存在于中、西部地区和东部地区之间.

城市流通系统:研究现状与一个综合性框架

现代流通产业的发展演变过程是伴随着现代城市的产生与发展过程进行的,现代城市是现代流通产业的载体,而城市则因为流通产业的发展而发展、壮大.因而,流通问题与城市问题是密不可分的.目前城市流通问题的研究集中在商业地理学领域,而传统流通理论则游离于该领域之外,这种游离造成了该领域研究的一些问题.本文在比较全面地回顾和评述了国内外学者对城市流通问题研究现状的基础上提出了一个综合性的研究框架,以期为城市流通问题的研究提供新的视角.     

组织信息体制、制度化关联与高技术企业集群治理效率

高技术企业集群是一种网络式中间体组织，其组织结构更多的表现为组织之间垂直方向和水平方向的信息关联关系。不同的信息关联形成不同的信息体制。高技术企业集群治理合约分为VC捆绑武治理合约、转换者式治理合约、主导企业式治理合约等三种典型形式．其治理合约的选择受制于信息体制的交易费用大小。信息体制有其特定的制度生存环境，并且具有不同的交易费用结构特征．必须使制度环境与信息体制相匹配。制度化关联与信息体制的耦合互动可以弥补组织信息体制内生的体制缺陷．降低总交易费用。制度环境的扰动和制度的历时关联影响治理合约的治理效率．治理合约需要做出相应的调遣．     

IPO anomalies and innovation capital

Innovation capital are typically expensed and/or unrecognized as assets under current generally accepted accounting principles. This results in accounting-related information asymmetry. This paper examines the association of innovation capital (as measured here by the proxies of R&D expenditures and granted patents) and initial public offerings (IPO) anomalies. These anomalies include initial IPO underpricing, duration of honeymoon (a distinct feature of the Taiwanese IPO environment), and long-term performance. The theoretical model underlying this research is a signaling model. The results indicate that more innovative firms are more likely to be underpriced, and have longer honeymoon periods than less innovative firms. Further, the more innovative firms have positive and growing long-term market-adjusted returns. This stands in contrast to the declining long-term stock performance of initial public offering firms that is evidenced in the literature. We conclude that pre-IPO research and development expenditures disclosed in the IPO prospectus, official monthly reports of newly developed patents released to the public, and the frequency of patent citations significantly signal both underpricing and future market performance of IPO firms in Taiwan.     

高技术企业的权变治理、管理者更替与企业永续发展

高技术企业的治理与规范化公司的治理存在很大的差异,甚至是本质上的差异。这种差异主要来自于高技术企业的人力资本价值和团队合作价值。但从企业长期发展来看,高技术企业必须平衡权威治理和企业永续发展的关系问题。本文运用企业权力主体竞争力模型分析高技术企业控制权结构,剖析了高技术企业的“两人治理结构”现象,揭示出保持高技术企业永续发展的两大主题——权变治理和管理者更替问题。     

Impact of sales force automation on technology-related stress, effort, and technology usage among salespeople

This study unveils factors affecting sales force automation (SFA) technology usage by salespeople. It differs from previous research by: (1) proposing a model that examines the consequences of task complexity on role perceptions and technology usage, and (2) understanding the negative repercussions of SFA technology on the user. The proposed model was tested using data from 150 salespeople employed by a national organization. The results suggest that integration of SFA technology induces adverse role perceptions in salespeople. However, controlling for extraneous variables, effort is significantly related to salespeople's usage of technology. Key managerial implications for theory and practice are discussed.
