How Issue Size, Risk, and Complexity are Influencing External Financing Costs: German IPOs Analyzed from an Economies of Scale Perspective

This paper is focused on the cost of raising capital in Germany. A cross-sectional analysis of flotation cost data for 117 IPOs over the years 1993–1998 is presented. We find average flotation costs to be 7.77 percent of gross proceeds, while underwriting fees average 5.01 percent. Our results extend the literature in two important directions. First, contrary to the conventional economies of scale view we find marginal spreads to be rather constant in gross proceeds and to be higher for more risky and more complex offerings. Fixed costs amount to 5 to 9 percent of underwriting fees. Second, by applying a principal component analysis we find issue size, an issuer risk factor, and an offering method complexity factor to have an economicaly meaningful impact on underwriting fees.     

Differential reporting in Germany - A historical analysis

Based on a contingent perspective of accounting change, this paper reviews the historical development of differential reporting in Germany, by drawing on primary and secondary sources. The main objective of the paper is to shed light on the driving forces and main influential parameters that have shaped the existing differential reporting framework. This historical approach supplies interesting insights for the current discussion on differential reporting in Germany produced by the EU Regulation on the application of International Accounting Standards.     

LABOUR SUPPLY ESTIMATION AND PUBLIC POLICY

Abstract. Economists devote considerable energies towards refining their econometric techniques to overcome difficulties connected with conducting empirical research. Despite advances in technique. it is not clear whether further refinement in this direction is worthwhile for policy purposes. It may be that no further amount of statistical adjustment of inadequate data will increase understanding, and that better data is simply necessary to add to our knowledge. But rarely is sufficient credit paid to new forms of data. In short, econometric technique is emphasized to the neglect of data innovation, as if new data were merely lying about waiting for an ingenious suggestion for use. This paper surveys advances of the last twenty five years in estimating labour supply for policy purposes with a view towards appreciating the relative contribution of both improvements in econometric technique as well as developments of new data.
After briefly detailing the key parameters which economists have sought to estimate, we describe the early 'first generation' research (circa 1970), which is plagued by problems of unobservable variables, measurement errors, truncation and selectivity bias, and non linear budget constraints. 'Second generation' research constitute attempts to resolve one or more of these difficulties, and the respective contribution of econometric technique and new data is acknowledged and assessed, including the contribution of data generated by large scale social experiments in which participants are randomly assigned to different guaranteed income plans and their labour supply behaviour measured.     

Stability and Segregation in Group Formation

This paper presents a model of group formation based on the assumption that individuals prefer to associate with people similar to them. It is shown that, in general, if the number of groups that can be formed is bounded, then a stable partition of the society into groups may not exist. (A partition is defined as stable if none of the individuals would prefer be in a different group than the one he is in.) However, if individuals' characteristics are one-dimensional, then a stable partition always exists. We give sufficient conditions for stable partitions to be segregating (in the sense that, for example, low-characteristic individuals are in one group and high-characteristic ones are in another) and Pareto efficient. In addition, we propose a dynamic model of individual myopic behavior describing the evolution of group formation to an eventual stable, segregating, and Pareto efficient partition.

公共物品供给主体的多元化研究

我国公共物品供给正在从政府一元化供给模式向政府、私营部门和非营利部门共同参与的多元化供给模式转变,这是政府公共物品供给模式回应经济主体多元化的转变。政府、私人组织和非营利组织在公共物品供给过程中,既存在竞争关系,也存在合作关系。最优制度安排的标准就是在多中心体制中寻求静态的稳定性和动态的适应性,以综合的供给模式实现公共物品供给的最优架构,达到效率和公平的统一。     

“Ideas” driven growth: the OECD evidence

This paper estimates the parameters of the ideas production function crucial to recent ideas-driven growth models. Using U. S. patents granted to residents in OECD countries to generate the stock of commercially used ideas, we provide evidence for two main findings. First, at the level of the production of ideas, we find evidence of increasing returns to scale in the stock of ideas and number of researchers, but marginal decreasing returns in each one of these factors. Second, we provide evidence of the association between ideas growth and economic growth for the OECD as a whole in the long run.JEL Classification: 031, 040The author would like to thank the helpful comments made by two anonymous referees, and by the editor, of the PEJ. The helpful discussions with Professor Mário Rui Silva are grateful acknowledged, too.     

论药品专利和公共健康问题——以人权和“价值平衡”理论为视角

WTO建立的TRIPS协议将包括药品在内的一切发明都纳入可以给予专利保护的范围，这使发展中国家在解决本国因艾滋病、结核病和疟疾等传染病引起的公共健康问题时，和发达国家相关药品的专利保护之间产生冲突。从当前全球的公共健康现状出发，运用人权和“价值平衡”理论对此分析，可以得出这样的结论：作为基本人权，发展中国家人民的生命健康权应该优于知识产权加以保护。     

家庭环境因素对大学生公众演讲焦虑水平的影响

调查家庭环境因素对中医院校大学生公众演讲焦虑水平的影响,希望能促进演讲能力培训课程教学研究工作。采用问卷调查法对参加演讲能力培训课程的学生的公众演讲焦虑水平和家庭环境因素进行调查分析。家庭环境中的娱乐性、知识性、组织性、控制性、亲密性等因素与对被试公众演讲焦虑水平有较高水平的负相关;其中,控制性的影响显著性较低,其它各项因素显著性较高。演讲能力培训课程教学研究工作者对选课学生的公众演讲焦虑形成的影响因素有深入了解,可以找到更好的切入点,通过心理学和教育学的专业知识和技术,帮助学生不断降低自身的公众演讲焦虑,提高自身的公众演讲能力。     

私利与公益的协调是可能的吗——斯蒂芬·杨“道德资本主义”经济伦理观解析

经济伦理学要追求私利与公益的和谐的、协调的统一。斯蒂芬.杨提出以道德资本主义的经济伦理观来有效协调两者的关系,对人们颇有启发。道德资本主义提倡将私利投入公益,践行者要有＂考虑整体的自我利益＂的意识。现实经济生活中有效地结合了私利与公益的成功企业,对于终结贫困的重大价值,道德资本主义本身所具有的最佳结合了超越性之理想与现实性之欲念的特点等为道德资本主义提供了可能性。考克斯原则是目前全球范围内践行道德资本主义的范例。但是,道德资本主义要真正落到实处还必须大力培养有原则的商业领导。
