We examine the impact of initial public offerings (IPOs) on rival firms and find that the valuation effects are insignificant. This insignificant reaction can be explained by offsetting information and competitive effects. Significant positive information effects are associated with IPOs in regulated industries and the first IPO in an industry following a period of dormancy. Significant negative competitive effects are associated with larger IPOs in competitive industries, those in relatively risky industries, those in high‐performing industries, and those in the technology sector. IPO firms that use the proceeds for debt repayment appear to represent a more significant competitive threat to rival firms relative to IPO firms that use their proceeds for other purposes.  相似文献

We examine four issues pertaining to initial public offerings (IPOs) using a survey of 438 chief financial officers (CFOs). First, why do firms go public? Second, is CFO sentiment stationary across bear and bull markets? Third, what concerns CFOs about going public? Fourth, do CFO perceptions correlate with returns? Results support funding for growth and liquidity as the primary reasons for IPOs. CFO sentiment is generally stationary in pre‐ and post‐bubble years. Managers are concerned with the direct costs of going public, such as underwriting fees, as well as indirect costs. We find a negative relation between a focus on immediate growth and long‐term abnormal returns.  相似文献

Political entrepreneurship occurs when an individual acts on a political profit opportunity. These profit opportunities can be divided into two categories: productive, and predatory. Productive opportunities enable entrepreneurs to profit from enhancing the efficiency of government, while predatory opportunities enable entrepreneurs to profit from forcibly transferring resources from some to others. This analysis shows that political institutions tend to favor predatory over productive political entrepreneurship, and shows that what is sometimes referred to as political exchange does not have the same efficiency characteristics as voluntary exchange in private markets.  相似文献

British public investment has declined sharply both as a share of GDP and as a share of government spending since the 1970s. Only part of this decline is explained by privatisation, which transferred some public investment to the private sector. More important was the very large and permanent reduction in public house‐building between the mid‐1970s and the early 1980s. Between the late 1980s and the early 1990s, the rate of public investment recovered somewhat, but after that time it declined again, reaching a record low in 1999. The most recent decline in public investment has affected a range of central government programmes, and it has not been significantly offset by investment under the Private Finance Initiative. The government now plans to increase investment spending, although levels look set to remain low by historical standards for some time to come.  相似文献

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.

现阶段,我国政府公共危机管理的绩效评价工作才刚刚起步,“官员问责”还存在着一些问题。在政府公共危机管理体系中,绩效评价和问责是较为薄弱的一环。文章通过对我国近几年发生的六起煤矿特别重大事故行政责任追究结果的分析,厘清我国政府公共危机管理绩效评价和问责存在的问题。在此基础上,借鉴国外政府公共危机管理绩效评价工作的做法,提出应分别从问责目标、问责主体、问责对象、问责内容、问责程序和方法、问责结果的应用等方面完善我国政府公共危机管理问责制。  相似文献

This paper examines the effects of government deficits, public investment, and public capital on welfare in the transition to an aging Japan by applying a simulated general equilibrium growth model. One of the main results of this paper is that targeting only high economic growth would mislead us as to economic policies, and that a policy to reduce future government deficits is most preferable for almost all generations, even though a cut in future deficits must be followed by a decrease in public investment, thus a decrease in public capital in the future.

This paper provides an evaluation of the spinoff of a for-profit company from the American Institute of Certified Public Accountants (AICPA), a nonprofit professional association. The evaluation is based on a review of the literature on public policy issues surrounding organizational conversions from nonprofit to for-profit legal status. Many criticisms of this for-profit spinoff were voiced by professional leaders and accounting regulators, and we demonstrate that these criticisms are grounded in widely recognized policy principles relating to nonprofit conversions. The public policy issues raised by this study have implications for the governance of professional associations in all disciplines.  相似文献
