Of the many activitiesof the Antitrust Division of theU.S. Department of Justice, we havesummarized some that raise interestingeconomic issues. We describe recentimprovements in the methodology to beused in ``coordinated effects' analysisof mergers. We also discuss four casesbrought by the DOJ that raise issues ofmarket definition, the influence ofcommon partial ownership of competitors,and the effects of fringe suppliers inconstraining collusion by large firms. 相似文献

Controlling for the Impact of Variable Liquidity in Commercial Real Estate Price Indices 总被引:6,自引:1,他引:6
Liquidity in private asset markets is notoriously variable over time. Therefore, indices of changes in market value that are based on asset transaction prices will systematically reflect intertemporal differences in the ease of selling a property. We define and develop a concept of "constant-liquidity value" in the context of a model that is characterized by pro-cyclical volume of trading. We then present an econometric model that allows for estimation of both a standard transaction-based price index and a constant-liquidity index. Our application to the NCREIF database reveals that, in the case of institutional commercial real estate investment, constant-liquidity values tend to lead transaction-based and appraisal-based indices in time, and also to display greater volatility and cycle amplitude. The differences can be significant for strategic investment policy viewed from a mean-variance portfolio optimization perspective. 相似文献

This study examines the association between activity-based costing and manufacturing performance. Results using a cross-sectional sample of manufacturing plants indicates that extensive ABC use is associated with higher quality levels and greater improvements in cycle time and quality, and is indirectly associated with manufacturing cost reductions through quality and cycle time improvements. However, on average, extensive ABC use has no significant association with return on assets. Instead, we find weak evidence that the association between ABC and accounting profitability is contingent on the plant's operational characteristics. 相似文献

Corporate Diversification: What Gets Discounted? 总被引:11,自引:0,他引:11
Prior literature finds that diversified firms sell at a discount relative to the sum of the imputed values of their business segments. We explore this documented discount and argue that it stems from risk–reducing effects of corporate diversification. Consistent with this risk–reduction hypothesis, we find that (a) shareholder losses in diversification are a function of firm leverage, (b) all equity firms do not exhibit a diversification discount, and (c) using book values of debt to compute excess value creates a downward bias for diversified firms. Overall, the results indicate that diversification is insignificantly related to excess firm value. 相似文献

Abstract This paper examines the circumstances in which financial reporting exists. Jensen and Meckling (1995 ) observe that where there are high knowledge transfer costs, then decentralisation is necessary; and that where decentralisation occurs there is a control problem, which can be addressed by providing a control system. I predict that where there are high knowledge transfer costs there will be a control system; if the control system uses financial reports, these will occur for activities with high knowledge transfer costs. The ability to decentralise is reduced where dependence makes it potentially costly to allow a subordinate to make decisions about the activity. The paper predicts that high dependence will be negatively associated with the existence of financial reports. The results confirm the predictions that financial reports are positively associated with knowledge transfer costs and negatively associated with dependence. 相似文献

We investigate the determinants of direct office real estate returns by analyzing rents, capital appraisals, and total returns. A recently compiled global database of major cities in Asia, Europe, and the United States provides a unique opportunity to give a macro-view on the effects of economic growth and supply and demand factors on nominal real estate returns. The global database provides quarterly observations from 1986 to 1999. To address the smoothness problem of appraisal-based price data and regulated rents, we employ the Generalized Method of Moments to estimate a dynamic panel-data model. The model allows us to combine the cross-sectional and time-series dimension in our quarterly data. We find that gross domestic product, inflation, unemployment, vacancy rate, and the available stock all have an effect on real estate returns. 相似文献

This paper shows that the firm has an incentive to issue multiple classes of debt that are differentiated by seniority to enhance securityholder tax-timing option values. The analysis establishes that there is at least one mix of senior and junior debt that maximizes the tax option gain from having multiple priority classes of debt. An analytic example provides specifications for the optimal amount of leverage and the optimal mix of senior and junior debt. Relative to the case of only one class of debt, a multiple debt priority structure increases the optimal amount of corporate leverage. 相似文献

Reframing science and other local knowledge traditions 总被引:2,自引:0,他引:2
David Turnbull 《Futures》1997,29(6):551-562
By recognizing science as a set of local practices it becomes possible to ‘decentre’ it and develop a framework within which all knowledge systems can be equitably compared. It is argued that all knowledge traditions are spatial in that they link people, sites and skills. In order to ensure the continued existence of the diversity of knowledge traditions rather than have them absorbed into the great imperialist archive we need to enable disparate knowledge traditions to work together through the creation of a third space in which the social organization of trust can be negotiated. 相似文献
