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.     

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。     

绿色中药产业初见成效 发展任重道远——对汉中市部分中药产业重点发展县的调查

近年来,汉中市实施＂发展绿色产业,建设绿色汉中＂的战略,中药产业逐渐成为汉中经济发展新的增长极。为了解汉中中药产业的发展情况以及银行业机构金融服务支持情况,笔者先后深入勉县、留坝、佛坪等中药材生产形成一定规模的县域,采取与当地政府部门、银行业机构座谈,深入农户中药材种植基地和实地察看加工企业等方式进行了专题调研,分析了其中问题并提出相关建议。     

“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.

浅析我国征地制度中"公共利益"界定与征地范围划分问题

在我国,土地征用权的法律规定主要来自《宪法》、《土地管理法》和《城市房地产管理法》。我国宪法,虽然赋予国家征用土地的权利,却没有为这种权利的行使划定明确的范围、界限、方式和程序;现行法律中关于土地征用权的规定互相矛盾,从而导致土地征用权的滥用,同时还存在对农民的补偿和安置不到位等问题。因此迫切需要完善土地征用制度,明确界定“公共利益”的范围,文章就此问题进行了初探,并提出了完善征地制度的建议。
