Despite the fact that international technology transfer has been widely studied its management still encounters many difficulties. To fully understand the issues that are relevant to the process of transferring production technology, it is necessary to determine the important factors that influence this process. Learning curves are often used as a means of determining the time required to become familiar with a transferred technology. The cases discussed in this paper have all employed learning curves, which were established at the outset of the transfer process and which turned out to be incorrect. As a consequence the envisaged efficiencies were not obtained. This phenomenon is partly due to the fact that when technology is transferred to a relatively inexperienced 'destination company', the curve is established based on the circumstances of the 'source company'. The case study findings lead to the conclusion that to establish a realistic curve a more comprehensive method is required than simply basing anticipated performance on that achieved at the source company.  相似文献

The purpose of this paper is to study how organizational rejuvenation is used to increase and support knowledge exploitation in multinational enterprises. Using case-study data to explore the theoretical arguments, interesting findings emerge. The main finding is that entrepreneurial activities in IT industry enable organizational rejuvenation with repercussions beyond the focal function. Other findings relate to how corporate entrepreneurship activities provide possibilities for continuous knowledge exploitation within the MNE and how entrepreneurial groups inside MNEs form the foundation from which the organizational rejuvenation originates. Finally, the form of organizational rejuvenation studied embraced both structural and behavioral changes. The authors acknowledge an equal share in the development of this article.  相似文献

We consider carefully the evidence from traded prices (as proxied by unit values) concerning the transmission of the effects of globalisation to domestic labour markets. Using standard index number techniques we decompose changes in sectoral import and export unit values into movements due to changes in pure prices of the initial bundle of goods imported or exported and changes due to upgrading of that bundle. Looking at the imports of selected European countries of textiles, clothing and footwear relative to engineering products we find evidence of strongly falling pure prices of the unskilled intensive products relative to the skilled products in the 1980s. This reinforces the view that import prices can capture the impact of globalisation in terms of falling relative prices for products produced with the intensive use of unskilled labour. However, the trends are not common across all the unskilled sectors; footwear is clearly an exception. In the absence of detailed domestic data, we look for reactions by domestic firms to increased import competition in movements in the price and composition of exports. We find evidence of stiff price competition from imports being associated with similar movements in export prices and no support for the view that import competition from low–wage countries has led to upgrading of the quality of exports.  相似文献

We extend Condorcet’s Jury Theorem (Essai sur l’application de l’analyse à la probabilité des décisions rendues à la pluralité des voix. De l’imprimerie royale, 1785) to weighted voting games with voters of two kinds: a fixed (possibly empty) set of ‘major’ voters with fixed weights, and an ever-increasing number of ‘minor’ voters, whose total weight is also fixed, but where each individual’s weight becomes negligible. As our main result, we obtain the limiting probability that the jury will arrive at the correct decision as a function of the competence of the few major players. As in Condorcet’s result the quota q = 1/2 is found to play a prominent role. I wish to thank Maurice Koster, Moshé Machover, Guillermo Owen and two anonymous referees for helpful comments.  相似文献

Background risk can influence the performance of insurance markets that must deal with adverse selection when applicants are risk vulnerable, since they are more averse to bearing the insurable risk as a result of their exposures to background risk. We show that background risk always results in a lower deductible for the incentive constrained contract, and that a broader range of markets attains the stable sequential equilibrium cross-subsidized pair of separating contracts. We conclude that background risk always improves the performance of markets for coverage against (insurable) foreground risks that must deal with adverse selection. We also find, however, that these improvements are never sufficient to offset the cost to insureds of bearing the background risk.  相似文献
