Findings in economic theory suggest that horizontalmergers involving firms with aggregate market shareless than 50% are unlikely to be motivated by theconsequent reduction in competitivity. The resultsarise because, absent cost efficiencies, quantity-settingfirms in small mergers are impoverished by the merger.We demonstrate that this conclusion is a consequence ofthe strong restrictions imposed on the demand function,and we identify a well-behaved demand function suchthat any set of merging firms benefits from the reductionin competition even when there are no cost efficiencies. 相似文献

Abstract This study sets out a backtesting framework applicable to the multiperiod-ahead forecasts from stochastic mortality models and uses it to evaluate the forecasting performance of six different stochastic mortality models applied to English & Welsh male mortality data. The models considered are the following: Lee-Carter’s 1992 one-factor model; a version of Renshaw-Haberman’s 2006 extension of the Lee-Carter model to allow for a cohort effect; the age-period-cohort model, which is a simplified version of Renshaw-Haberman; Cairns, Blake, and Dowd’s 2006 two-factor model; and two generalized versions of the last named with an added cohort effect. For the data set used herein, the results from applying this methodology suggest that the models perform adequately by most backtests and that prediction intervals that incorporate parameter uncertainty are wider than those that do not. We also find little difference between the performances of five of the models, but the remaining model shows considerable forecast instability. 相似文献

This paper examines how the relationships linking money to real output are altered when an international-domestic interest rate gap is included in the model. The results indicate that both the international-domestic interest rate gap and term structure exert a statistically significant effect on real economic activity. In addition, fluctuations in these variables contain significant information about future changes in real output. An interesting finding is that while the term structure dominates the international-domestic interest rate gap when estimating the entire time period, 1970:1–1996:4, the international-domestic interest rate gap clearly dominates in the more recent time period, 1985:1–1996:4. 相似文献

This paper sets out to explore the role of the employer in successful welfare-to-work transitions. We demonstrate the uses of administrative records in identifying the types of firms that repeatedly hire welfare recipients. We also develop sets of criteria to identify “successful” outcomes. Our results suggest that there is substantial untapped potential for using administrative data to identify not simply which industries hire welfare recipients but those that are most likely to provide recipients with long-lasting jobs, or jobs accompanied by sustained removal from welfare dependency. 相似文献

Control and governance theories recognize that exchange partners are subject to two general forms of control, the unilateral
authority of one firm and bilateral expectations extending from their social bond. In this way, a supplier both exerts unilateral,
authority-based controls and is subject to socially-based, bilateral controls as it attempts to manage its brand successfully
through reseller channels. Such control is being challenged by suppliers’ growing relative dependence on increasingly dominant
resellers in many industries. Yet the impact of supplier relative dependence on the efficacy of control-based governance in
the supplier’s channel is not well understood. To address this gap, we specify and test a control model moderated by relative
dependence involving the conceptualization and measurement of governance at the level of specific control processes: incenting,
monitoring, and enforcing. Our empirical findings show relative dependence undercuts the effectiveness of certain unilateral
and bilateral control processes while enhancing the effectiveness of others, largely supporting our dual suppositions that
each control process operates through a specialized behavioral mechanism and that these underlying mechanisms are differentially
impacted by relative dependence. We offer implications of these findings for managers and identify our contributions to channel
theory and research. 相似文献

Drawing upon a series of interviews conducted with leading practitioners and opinion formulators in the social, ethical and environmental audit arena, together with an extensive review of recent literature in the area, this paper offers a critical appraisal of current developments in the newly revitalized social audit movement. We particularly question whether in their enthusiasm for bringing social audit into the mainstream of current business thinking its advocates risk compromising the democratic ideals of the founding fathers of the movement. A particular concern raised is that without real change in corporate governance structures, social audit could become monopolized by consultants and/or corporate management and hence amount to little more than a skilfully controlled public relations exercise. 相似文献

Some economists use an export tax, which alters the domestic relative price of exports, to model a voluntary export restraint,
which is a restriction on the quantity of exports with restriction-induced rents accruing to the exporting country. Implicit
in this approach is the presumption that the two policies are equivalent. In a very general model that allows for a finite
number of goods and factors and intermediated goods and joint production, we demonstrate that, in general, this is, in fact,
not the case. Specifically, from the exporting country’s perspective, the real income effects of the two policies are nonequivalent. 相似文献
