A bstract . Neoclassical economic theory asserts that when the assumptions of perfect competition apply to a market economy , the allocation of inputs and/or outputs is such that by additional inputs or outputs no individual's welfare can be improved without diminishing some other individual's. That is, it is considered Pareto Efficient. When imperfect markets exist, however, externalities —influences from outside the economic process—in production and exchange, and indivisibilities—benefits or costs which cannot be allocated to or assessed against the individuals who enjoy or occasion them—appear and the market ceases to be an efficiently operated one. It is argued here that a fourth category of factors exists which may interfere with economic efficiency and that these factors are sociological in nature, factors arising from such considerations as class, status, role and power.  相似文献

The objective of this research project was to develop a validated scale to measure Level 5 Leadership using the Collins ( 2005 ) Level 5 attributes. An expert panel reduced the 99 attributes from Collins to 74. The 349 participants evaluated their bosses on a 10‐point semantic differential scale for each attribute. A review of the literature suggested that Level 5 leadership and servant leadership represent the same concept; thus the study used a 10‐item servant leadership scale to check for concurrent validity. Additionally, Collins proposed eight untested questions to determine if individuals qualify as Level 5 leaders. Principal component analysis resulted in two factors that explained 55.2% of the variance; these factors matched Collins's proposed personal humility and professional will constructs. The final instrument contains five attributes of personal humility and five attributes of professional will that yield Cronbach alphas of .83 and .83, respectively. The analysis also revealed statistically significant positive relationships between the Level 5 attributes, servant leadership, and a single factor that represented Collins's eight questions.  相似文献

The primary objective of this paper is to explore the ways in which the characteristics of owner-managers influence the extent to which their firms are embedded within local clusters of economic activity. Data are drawn from an interview survey of a random sample of small metal-working firms in Sheffield, UK. The data are analysed using non-parametric statistical methods to test bivariate relationships. Owner-manager attributes are found to have no influence on the extent of the use of local material supply networks but they do influence the extent of dependence on local markets. Owner-managers born and bred in the local region with limited formal education, working as an operative (rather than executive) prior to start up and with many years experience are more likely to rely on local markets. Owner-manager characteristics are also linked to participation in business networks. Those with most experience and those previously working for large firms are more likely to participate. It is concluded that owner-manager attributes can be important in explaining the level of embeddedness of small firms in a cluster of economic activity and that such attributes need to be built into theories of cluster behaviour.  相似文献

This study is concerned with an effort to analyze changes in costs and prices in the Australian economy by tracing the effects of changes in wages and import prices through the stages of production, using a disaggregated input-output model with lags. The object of constructing the model was to improve, by introducing lags, the accuracy of predictions of the effect of cost changes on prices, and to show the lag structures. Data problems encountered are discussed, and the need for integration of price statistics to enhance their usefulness for analyses such as this is emphasized. Concepts and sources of data are discussed in some detail in an appendix.  相似文献

Many multiregional input–output (MRIO) databases are used to calculate consumption-based accounts. Results feature in climate policy discussion on emissions reduction responsibilities; yet studies show that outcomes produced by each database differ. This paper compares the emissions associated with value chains from Eora, EXIOBASE, GTAP and WIOD. Structural path analysis identifies the largest paths in each database and the differences in common paths are calculated. For the top 100 value chain paths that contain the largest difference, structural path decomposition is used to identify the contribution each part of the value chain makes towards the difference. The results identify and quantify key flows that are the cause of difference in the databases. From these, we can conclude that key MRIO database construction decisions, such as using the residence or territorial principle for emissions allocation and whether energy spends are reallocated based on physical data, are the major causes of differences.  相似文献

A more competitive and export-oriented manufacturing sector is an important objective of the Australian Labor Government's economic strategy. In furthering this objective levels of tariff protection have been lowered and foreign exchange markets deregulated. The strategy has been boosted by the competitive gain afforded by depreciation of the Australian dollar in 1985 and 1986. This article offers estimates of the size of Australian manufacturing investment in export-creating capacity over the period 1980-81 to 1987-88. A breakdown of these estimates by individual industries is also provided.
Our estimates indicate an improving trend since depreciation of the Australian dollar. However, this improvement has been from a low base. Moreover, the levels of investment in export-creating capacity have yet to attain the levels prevailing in the early 1980s, and there are worrying signs that the improving trend stalled toward the end of the period. However, the breakdown of our estimates by industry groupings shows positive changes in the pattern of investment in export-creating capacity. There has been a movement away from resource-based manufactures and a larger share for elaborately transformed manufactures. This is a favourable shift in emphasis since such technologically sophisticated manufactures have been amongst the fastest growing world markets.  相似文献

This paper is offered as a constructive comment on a previously published article. Using two separate approaches, the authors reexamine data presented by Valencia (1989), and suggest an alternative interpretation of the cultural value orientations among Hispanic and White ethnic groups. Theoretical and methodological discussion is provided in an attempt to show how utilization of different methodologies can derive different conclusions, and result in different marketing strategy recommendations.  相似文献

Why do otherwise well-intentioned managers make decisions that have negative social or environmental consequences? To answer this question, the authors combine the literature on construal level theory with the compromise effect to explore the circumstances that lead to seemingly unethical decision-making. The results of two studies suggest that the degree to which managers make high-risk tradeoffs is highly influenced by how they mentally represent the decision context. The authors find that managers are more likely to make seemingly unethical tradeoffs when psychological distance is high (rather than low) and when they are forced to choose between competing alternatives. However, when given the option not to choose, managers better reflect on the consequences of each alternative, and thus become more likely to choose options with less risk of negative consequences. The results suggest that simply offering managers the option not to choose may reduce psychological distance and help organizations avoid seemingly unethical decision-making.  相似文献

The privatization of United Kingdom utilities after 1979 established a regulatory regime based around price capping rather than return capping. This innovation was intended to provide a predictable framework that encouraged efficiency. An event methodology was used to examine stock market reaction to the main regulatory announcements affecting 12 Regional Electric Companies from flotation to 1995. The results indicate that the regulatory announcements were only a minor contributor to the persistent abnormal returns observed. The low connection between regulatory events, efficiency changes and abnormal returns at company level lead to a conclusion that the initial structural and control frameworks dominated the regulatory framework.  相似文献
