The issue of resource utilization is important in the resource-based stream of work, since the ability of firms to utilize resources is a key indicator of their competitive abilities. This paper specifies why some firms might be better at utilizing resources than others. Thereafter, it demonstrates how to empirically ascertain differences in resource utilization patterns between firms using the U.S. telecommunications industry as a context. The data envelopment analysis procedure (DEA), which is a firm-level resource utilization measure, is used. This procedure can be useful for the resource-based approach research agenda since performance is measured in resource terms. DEA is applied to measure variations in different dimensions of resource utilization for the firms making up the local operating sector of the telecommunications industry. The use of DEA to guide empirical research and address theoretical issues within the resource-based paradigm is illustrated, using the resource utilization index for the telecommunications firms as the measure of strategic performance. © 1998 John Wiley & Sons, Ltd. 相似文献

This analysis evaluates the impact of corporate debt in influencing mergers of local exchange companies in the United States telecommunications industry between 1988 and 2001. Firms’ financial structures significantly affect behavior and performance; yet no evidence has shown how firms’ financial structures influence their merger activities. The impact of corporate debt levels on the various mergers that took place during the merger wave in the sector is significantly negative for the first set of mergers carried out, and significantly negative, but with smaller impact, for the second set of mergers. The results support the idea that firms with high debt levels can be monitored carefully, precluding engagement in potentially-risky mergers so as to not engender negative financial outcomes. 相似文献

This article presents the outcomes of an evaluation of the impact of the series of mergers of the local exchange companies that have taken place between 1988 and 2001 on an important measure of performance of the firms undergoing the mergers. The analysis reveals that after firms have undertaken one merger they experience little or no growth after such mergers, but the impact of second mergers on firm growth have been negative. If an important motive in undertaking mergers has been to enhance firm growth, then the merger waves that have been approved and consummated have led to performance declines. The impacts of the merger wave on the growth of the telecommunications sector firms have been negative. 相似文献

We consider a Walrasian exchange economy in which an agent is characterized by a utility function, a random endowment vector,
and a function that specifies the minimum expenditure necessary for survival at a given price system. If at any equilibrium
price system, the income of the agent is no more than the minimum expenditure for survival, it is ruined. The main results
characterize the probability of ruin when the number of agents is large. The implications of stochastic dependence among agents
are explored. 相似文献

Using contemporary historical data, the analysis reported in this article has evaluated the impact of the various mergers of the local exchange companies that took place between 1988 and 2001 on financial performance. Performance was measured using an important metric normally used to measure synergies of firms undergoing mergers. The analysis has revealed that the relative cash flow variable for firms worsened after mergers. If the synergy motive had been primary in influencing merger decisions, and also approvals, then the past mergers approved led to decreased performance levels and corresponding welfare losses for American consumers; thus, the mergers of communications common carriers were not in the interest of the public, the shareholders and customers. On the other hand, given the negative outcomes, views that the quiet life, hubris or a quest for possible market power motivated the mergers could be discarded. The lessons of such contemporary historical analysis have suggested that antitrust oppositions to contemporary telecommunications sector mergers may have basis in fact and salient evidence. 相似文献

The paper develops a model of a competitive world in which several countries are engaged in the production, consumption, and exchange of many commodities over time. Each agent produces a single good, and trades it for the required inputs and consumption goods. The plans of the agents are based on an optimization exercise involving a constrained maximization of a discounted sum of one period utilities. All the relevant functional relationships are assumed to be loglinear. The principal results deal with the existence and characterization of the sequence of temporary equilibria. 相似文献

Summary We examine a discrete-time aggregative model of discounted dynamic optimization where the felicity function depends on both consumption and capital stock. The need for studying such models has been stressed in the theory of optimal growth and also in the economics of natural resources. We identify conditions under which the optimal program is monotone. In our framework, the optimal program can exhibit cyclic behavior for all discount factors close to one. We also present an example to show that our model can exhibit optimal behavior which is chaotic in both topological and ergodic senses.We would like to thank V. Bala, J. Benhabib, P. Dasgupta, R.
