An Empirical Analysis of Entrant and Incumbent Bidding in Road Construction Auctions 总被引:3,自引:0,他引:3
Dakshina G. De Silva Timothy Dunne Georgia Kosmopoulou 《The Journal of industrial economics》2003,51(3):295-316
This paper explores differences in the bidding patterns of entrants and incumbents in road construction auctions. We find that entrants bid more aggressively and win auctions with significantly lower bids than incumbents. The differences in their bidding patterns are consistent with a model of auctions in which the distribution of an entrant's costs exhibits greater dispersion than that of an incumbent's and relations of stochastic dominance in the distributions do not persist for the entire range of estimated costs. We also find that more efficient firms bid, on average, more aggressively and firms with greater backlogs bid less aggressively. 相似文献

The present study explores three uncertainty reduction mechanisms that arise in the context of business alliance formation to assess whether these same mechanisms also operate in the development of alliances between non-profits and businesses. Secondary data from field-based case studies of Latin American cross-sector alliances are the focus of this analysis. The findings show that the same mechanisms operate to reduce uncertainty in cross-sector alliance formation and that alliance experience appears to determine the presence of some mechanisms. 相似文献

This paper draws attention for the fact that traditional Data Envelopment Analysis (DEA) models do not provide the closest possible targets (or peers) to inefficient units, and presents a procedure to obtain such targets.It focuses on non-oriented efficiency measures (which assume that production units are able to control, and thus change, inputs and outputs simultaneously) both measured in relation to a Free Disposal Hull (FDH) technology and in relation to a convex technology. The approaches developed for finding close targets are applied to a sample of Portuguese bank branches. 相似文献

What are the most effective learning strategies for firms given the characteristics of their knowledge environment? This paper addresses this question by documenting the major changes in the knowledge environment of the pharmaceutical industry, with a particular emphasis on the period since the emergence of biotechnology, and discussing the related changes in the learning strategies of established pharmaceutical firms. Both the historical analysis and a review of the empirical research on organizational learning and knowledge transfer reveal a strong emphasis of firms on external learning through interfirm collaborations and sourcing of external knowledge. This learning strategy seems to be driven by the speed, uncertainty, and dispersion of knowledge developments in the industry. Studying the connections between the knowledge environment and the effectiveness of organizational learning processes is important to understand organizational change and adaptation, and is an area of research that deserves further attention. 相似文献

This paper presents capital services estimates for 26 Portuguese industries for the 1977–2003 period. The estimation procedure follows an integrated approach under which the flows of capital services are approximated as a proportion of the capital stock converted into standard efficiency units. Our findings suggest a close proximity between the evolution of capital flows and the observed fluctuations of Portuguese macroeconomic growth. TFP growth estimates based on growth accounting reveal, furthermore, a very disappointing performance of the Portuguese economy during the period under study, with an average annual rate of TFP growth of 0.8% being observed. Performance varies across industries, but the bulk of activities show very modest rates of TFP growth. 相似文献

Anderson and vanWincoop developed what has become the standard framework for framing and interpreting empirical work using the gravity model. Their framework relies heavily on an assumption of symmetry among countries. For issues related to North‐South trade, this assumption is problematic. In this paper, we develop an asymmetric extension of the Anderson–vanWincoop framework appropriate to the analysis of North‐South trade, where Northern countries produce differentiated goods and Southern countries homogenous ones. In addition, we use an appropriately extended version of Baier and Bergtrand and Taylor linear expansion – thus permitting its estimation using (good old) OLS. The result is an empirical model that (i) is better suited to the analysis of North‐South trade, (ii) is easy to estimate and compute comparative statics, not requiring a customised NLS routine and, given the way the South is included, (iii) provides a simple explanation of zero trade flows between some country pairs, a fact still not fully explained in the literature. As an illustration of its use, we examine the empirical link between foreign aid and trade. 相似文献

The present study analyses research conducted in Service Dominant Logic (S-D logic), providing an overview of its intellectual structure. For that purpose, a structured approach was adopted through the implementation of bibliometric methods, using co-citation analysis combined with performance analysis and an integrative science mapping approach, which considered a timeline, a graph, and a distance-based perspective. This allowed the identification of the leading authors and of six clusters of articles based on bibliographic coupling, along with the most prominent research themes clustered in five subdomains of research based on co-occurrence of terms. The networks extracted show the associations between the main articles and concepts treated by the S-D logic community, unveiling the salient challenges and prospective expansion facing its future theoretical and practical context. 相似文献
