Globally aquaculture has been increasing rapidly and already accounts for nearly half of all food fish consumed. For developing countries, which produce 90% of the world’s output, aquaculture is a source of protein, employment, income and of foreign exchange. Southeast Asia is an area which has experienced this “blue revolution”. Total aquaculture output in the region increased from less than two million tonnes in 1990 to more than eight million tonnes in 2006. Moreover, the region’s pace of expansion has accelerated. Annual average growth rates in output from 2000 to 2006 were more than double those from 1990 to 2000. Already more than a quarter of food fish in Southeast Asia comes from aquaculture.  相似文献

This article examines the implications that the moment of market entry has for the effect of capabilities and competitive tactics on firm performance, using a sample of 253 companies from the information and communications technology industry. The results show that technical capabilities and low cost orientation are learning factors in the firms' performance, regardless of the moment of entry into the market. The study shows how the two perspectives of competitive strategy and resource-based view complement each other to incorporate different competitive factors in a coherent model for the study of entry timing. The study takes the sustainability model of competitive advantage further, by demonstrating that certain capabilities and competitive tactics can allow pioneers and early followers to achieve and maintain superior performance in a dynamic, hostile and with high level of imitation industry. This study also shows that the availability of a combination of marketing capabilities and low cost orientation will allow late followers' firms to take advantage of early entrants' mistakes.  相似文献

Web 2.0 technologies are increasingly being used within all knowledge management processes. This paper extends previous studies on the use of internet technologies and knowledge management by analyzing factors affecting knowledge sharing through Web 2.0 technologies within small and medium-sized enterprises (SMEs). Drawing upon the technology-organization-environment framework, a model is developed to examine how distinct contextual factors influence the use of Web 2.0 technologies for knowledge sharing. A data set of Spanish SMEs is used to test the conceptual model and hypotheses. Results show that knowledge sharing through Web 2.0 technologies emerges from internal organizational and technological resources rather than from external pressure.  相似文献

Responses to the financial crisis are undermining the Chinese walls painfully built between monetary and fiscal authorities. Central banks and state treasuries are working side by side as lenders of last resort. Central banks are helping economic ministers with purchases of public debt and discounting of private paper. Regulation and control of financial institutions is now a political football. Central banks must be seen again as market-dependent institutions in a world of currency competition. Privatisation in law or in fact is back on the table.  相似文献

We analyze the incentives of a vertically integrated firm, which is a regulated monopolist in the wholesale market and competes with an entrant in the retail market, to invest and to give access to a new wholesale technology. The new technology represents a non-drastic innovation that produces retail services of a higher quality than the old technology, and is left unregulated. We show that for intermediate values of the access price for the old technology, the vertically integrated firm may decide not to invest. When investment occurs, the vertically integrated firm may be induced to give access to the entrant for a low access price for the old technology. Furthermore, when both firms can invest, investment occurs under a larger set of circumstances, and it is the entrant the firm that invests in more cases. We also discuss the implications for the regulation of the old technology.  相似文献

Job search methods and outcomes   总被引:2,自引:0,他引:2  
Using Portuguese data, this paper investigates the effects ofjob search methods on escape rates from unemployment and ofjob-finding methods on earnings. The effectiveness of the jobsearch process is also evaluated in terms of the periodicityof the resulting job match. Emphasis is accorded the role ofthe public employment service. Despite its frequency as a searchvehicle, the state employment agency is shown to have a lowhit rate, and to lead to lower-paying, shorter-lasting jobs.  相似文献

We argue that the equation commonly used in the estimation of the wealth effect on consumption might be unsuitable for that purpose. In particular, if the usual assumptions are employed, the derivation of the equation implies that the wealth effect is indeterminate. Furthermore, it implies that the estimate of the wealth effect should decrease when asset wealth volatility increases. Estimation of a Markov-switching model of the usual long-run aggregate consumption equation provides evidence favourable to the indeterminacy hypothesis.  相似文献

Universal service objectives are pervasive in telecommunications, and have gained new relevance after the introduction of competition in many markets. Despite their policy relevance, little work has been done allowing for a thorough discussion of instruments designed to achieve universal service objectives under competition. We intend to fill this gap, and disaggregate the problem into interacting forms of regulatory intervention such as uniform pricing and coverage constraints. It is shown that these are not competitively neutral and may have far-reaching strategic effects. Under uniform pricing, equilibrium coverage of both incumbent and entrant may be lower than without regulation. These effects depend on which measures are imposed at the same time, thus no single measure can be evaluated in isolation. We also point out that different groups of consumers are affected in different ways, making welfare comparisons difficult.  相似文献

We study global games with strategic substitutes. Specifically, for a class of binary‐action, ‐player games with strategic substitutes, we prove that under payoff asymmetry, as incomplete information vanishes, the global games approach selects a unique equilibrium. We characterize this equilibrium profile ; players employ switching strategies at different cutoff signals, the order of which is directly determined by payoff asymmetry. We provide examples that illustrate our result and its connection with dominance solvability. We extend the global game literature, which has thus far been developed for games with strategic complementarities, to new applications in industrial organization, collective action problems, finance, etc .  相似文献
