We consider demand function competition with a finite number of agents and private information. We show that any degree of market power can arise in the unique equilibrium under an information structure that is arbitrarily close to complete information. Regardless of the number of agents and the correlation of payoff shocks, market power may be arbitrarily close to zero (the competitive outcome) or arbitrarily large (so there is no trade). By contrast, price volatility is always lower than the variance of the aggregate shock across all information structures. Alternative trading mechanisms lead to very distinct bounds as a comparison with Cournot competition establishes. 相似文献

Special purpose acquisition companies (SPACs) are created to raise capital and then find non-listed operating companies with which to merge. While most of the extant research has focused on SPAC initial public offerings, we study what happens when SPACs announce business combinations. Our analysis of 236 ‘deSPACs’ completed between January 2012 and June 2021 in the United States documents an average short-term announcement return of +7.4% and a 1-year abnormal return of −14.1% (−18.0% over 2 years) for public investors beginning from the merger announcement. Short-term returns decrease with longer times from initial public offering until announcement. 相似文献

Building on social exchange theory and attribution theory, this study unpacks the relationship between employees' perceptions of organizational politics and job performance, considering the mediating effect of career plateau beliefs and the moderating effect of leader interpersonal unfairness. The findings provide empirical support for the theoretical predictions. An important reason for which perceptions of dysfunctional organizational politics reduce job performance is that employees develop beliefs that opportunities for their career development are limited. This mediating role of career plateau beliefs is particularly salient to the extent that employees are exposed to organizational leaders who treat them with disrespect. Organizations can mitigate the risk that highly politicized decision-making processes lead to negative performance outcomes by stimulating fair interpersonal relationships. 相似文献

This study presents binary comparisons of real output and labour productivity in manufacturing in Japan, South Korea and the U.S.A. in 1975, made according to an "industry of origin approach." The 1975 benchmark comparisons have been updated to 1985. Value added per hour worked in Japanese manufacturing increased from 54 percent of the U.S. level in 1975 to 76 percent in 1985. In certain important branches such as electrical machinery, metal products and machinery and transport equipment, productivity leadership shifted to Japan. In South Korea, labour productivity in manufacturing increased rapidly from 1975 to 1985, both in absolute terms and relative to the U.S.A. Nevertheless, in 1985 value added per hour worked was only 14 percent of the U.S. level. 相似文献

This paper aims at classifying countries on the basis of a multitude of country characteristics using cluster and factor analysis. The results of the analysis are in particular compared with the categories of least developed countries (LLDCs) and of newly industrialized countries (NICs) used by international agencies. The LLDCs clearly emerge as a seperate group from the analysis; but some countries presently included do not belong to this group, while some countries not included have LLDC characteristics. The NICs do not emerge as a separate homogeneous group. Clearly the criteria presently used for NICs are quite narrow. 相似文献

We solve explicitly a two-dimensional singular control problem of finite fuel type for an infinite time horizon. The problem stems from the optimal liquidation of an asset position in a financial market with multiplicative and transient price impact. Liquidity is stochastic in that the volume effect process, which determines the intertemporal resilience of the market in the spirit of Predoiu et al. (SIAM J. Financ. Math. 2:183–212, 2011), is taken to be stochastic, being driven by its own random noise. The optimal control is obtained as the local time of a diffusion process reflected at a non-constant free boundary. To solve the HJB variational inequality and prove optimality, we need a combination of probabilistic arguments and calculus of variations methods, involving Laplace transforms of inverse local times for diffusions reflected at elastic boundaries. 相似文献

UK mutual fund performance: Skill or luck? 总被引:1,自引:0,他引:1
Using a comprehensive data set on (surviving and non-surviving) UK equity mutual funds, we use a cross-section bootstrap methodology to distinguish between ‘skill’ and ‘luck’ for individual funds. This methodology allows for non-normality in the idiosyncratic risk of the funds — a major issue when considering those funds which appear to be either very good or very bad performers, since these are the funds which investors are primarily interested in identifying. Our study points to the existence of stock picking ability among a relatively small number of top performing UK equity mutual funds (i.e. performance which is not solely due to good luck). At the negative end of the performance scale, our analysis strongly rejects the hypothesis that most poor performing funds are merely unlucky. Most of these funds demonstrate ‘bad skill’. Recursive estimation and Kalman ‘smoothed’ coefficients indicate temporal stability in the ex-post performance alpha's of winner and loser portfolios. We also find performance persistence amongst loser but not amongst winner funds. 相似文献

This article examines the intersection of the project management body of knowledge with new product development (NPD). The area under examination is the development of consumer products that have a significant engineering production content. It is concluded that the project management method, with its structured task definition and software tools, is generally useful for managing NPD projects. However, in some areas, project management incompletely meets the needs of NPD. Specifically, NPD is characterized by complex interrelated activities and large uncertainties about precisely which solution path will be taken, such that the full scope of the project can often not be anticipated beforehand. The article identifies that more research is required to validate the stage‐gate and lean project management methods. Whereas cost is the primary focus in project management, with NPD there is a need to consider both cost and income (from product sales) in making strategic decisions. Communication and human resource management are important factors in NPD success, but existing project management perspectives have little to say about the social and behavioral aspects, such as organizational culture, team dynamics, and leadership styles, especially not for NPD. Current project management practices are very much based on “output control” (targets, appraisal, rewards, management by objectives), which the human resource management literature identifies as inhibiting innovation. There is also likely to exist an intersection, as yet poorly understood, between project management and knowledge management, particularly for innovation processes such as NPD. For practitioners, the main message is that the project management method provides a basic, but imperfect, tool for managing NPD. The relevance for researchers is that gaps have been identified in the project management method as it is currently applied to NPD. Several places are identified where further research is required to (a) better understand the causality between factors (e.g., human resource management) and project success and (b) adapt project management methods to better serve the NPD process. 相似文献

This paper analyses the evolution of bank profitability from 2005 to 2016, with a focus on the period covering both the global financial crisis and the euro area crisis. To accomplish this, we constructed a dataset that includes financial statement information from 310 euro area banks. Using a dual approach – a ‘bottom-up’ approach as applied by bank analysts and macroeconomists' ‘top-down’ approach, we find that the profitability of euro area banks was hit by two shocks of different nature. The Lehman Brothers collapse affected mostly big banks with diversified portfolios via losses in their securities investment. The subsequent euro area debt crisis and economic recession hit more traditional banks specialising in retail lending activities, mainly through increasing impairment costs. If the first shock had a one-off impact on bank profitability, the second shock is far more long-lasting and is still depressing the profitability of banks in peripheral Europe. 相似文献
