This paper investigates the interrelationship between a firm's incentive to engage in international predatory pricing and its domestic vertical industry ties in the context of the deep-pockct theory of predation. The deep pocket stems from a vertically integrated firm's ability to shift funds between its upstream and downstream divisions. enabling it to prey on vertically unintegrated upstream competitors. Vertical integration is shown to function as a cause of and a deterrent to foreign predatory behavior.  相似文献

\"This paper tests a central prediction of vintage growth models of urban structure: that there are discontinuities in the population density function. The data set covers quarter sections in Chicago in 1980. Using such highly disaggregated data is critical because discontinuities are less likely to be found the larger is the unit of observation. Both a switching regression model and a nonparametric estimator reveal discontinuities and upward-sloping segments in the function, which supports the vintage growth model.\"  相似文献

This empirical study extends the work of Coakley et al. (Manchester School, Vol. 72 (2004), pp. 569–590) with respect to the Feldstein–Horioka puzzle for a sample of 47 developing countries. The study examines the savings–investment relationship through a comparison of the Feldstein–Horioka cross‐section estimator results with the results obtained from a mean group estimator allowing for the cross‐section dependence and permanent shocks to the current account. The mean group estimator results indicate higher capital mobility with a savings coefficient of 0.36, 25 per cent lower than the estimates based on the cross‐section estimator, for the whole sample with little variation across subregions.  相似文献

abstract    Business groups are the primary form of managing large business organizations outside North America. This paper provides a systematic and integrative framework for understanding business groups. We argue that existing theoretical perspectives of business groups pay attention to four critical external contexts, each of which draws from a specific theoretical perspective: market conditions (transaction cost theory), social relationships (relational perspective), political factors (political economy perspective), and external monitoring mechanisms (agency theory). Business groups adapt to these external forces by deploying various internal mechanisms along two key dimensions: one focuses on the distinctive roles of the group affiliates (horizontal connectedness) and the other focuses on coupling and order between the parent firm and its affiliates (vertical linkages). Based on these two dimensions, a typology of business group forms is developed: network (N-form), club (C-form), holding (H-form), and multidivisional (M-form). Utilizing this model we provide research questions which facilitate an improved future research agenda.  相似文献

We investigate how closely NBA teams play up to their potential. We find that shooting, rebounding, stealing the ball and blocking shots raise the number of potential wins while turnovers lower it. We also learn that better coaching and defensive prowess raise a team's win efficiency. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

We introduce a new panel data estimation technique for production and cost functions, the recursive thick frontier approach (RTFA). RTFA has two advantages over existing econometric frontier methods. First, technical inefficiency is allowed to be dependent on the explanatory variables of the frontier model. Secondly, RTFA does not hinge on distributional assumptions on the inefficiency component of the error term. We show by means of simulation experiments that RTFA outperforms the popular stochastic frontier approach and the ‘within’ ordinary least squares estimator for realistic parameterizations of a productivity model. Although RTFAs formal statistical properties are unknown, we argue, based on these simulation experiments, that RTFA is a useful complement to existing methods.  相似文献

Abstract
Russia has recently embarked on a dramatic program of privatisation as part of the process of shock therapy which aims to convert the command economy to a market economy. This program has been undertaken in the absence of a well-developed set of institutions needed for the proper functioning of a market economy. These institutions include a legal system, a related system of property rights, a credit system, a system of commercial banks, classified advertising, an accounting system and others including a sound currency and a social safety net. In the absence of these institutions the incentives facing agents in economic transactions have been perverted. This has led to criminalisation of the economy, dramatic falls in production, loss of confidence in all aspects of commerce, and political instability. The recent Russian experience of privatisation has important lessons for other economies in transition, for developing economies and for economic theory.  相似文献
