The managerial competencies required by professionals in the construction industry in Tanzania to operate effectively in a business environment which is changing as a result of a transition from a socialist to a free-enterprise economy, economic liberalization, globalization and regionalization are explored through a qualitative study. The study reveals that local Tanzanian construction firms are finding it difficult to compete with foreign companies for projects. This is mainly because Tanzanian professionals lack the competencies required to compete and manage projects in a liberalized market economy.

The study thus highlights the need for Tanzanian construction professionals to acquire a better grasp of both occupational and organizational competencies. In this respect, it is suggested that they need post-experience training in order to acquire the competencies required to function successfully in a commercial environment.  相似文献

This study analyzed the hyperlink (co-link) network structure among companies in global Corporate Social Responsibility (CSR) system. This study measured network variables such as density and centrality, including degree centrality, eigenvector centrality, closeness, and betweenness. The results indicated that European companies had relatively central roles in the global CSR system. In addition the higher performing companies are more active their CSR practices. Also, the results revealed that the industrial type of companies was not significantly associated with its CSR practices.  相似文献

Conclusion Deficit spending and money-supply expansion do not eliminate recessions. Theycause recessions. This fact will never be understood unless economists and government policymakers stop trying to micro-manage the economy, and start studying what their actions are doing to the structure of production. Heavy inflation of the money supply followed by sharp cutbacks change the rules right in the middle of the game for millions of businesses in the economy. For the last 40 years, government expansionary policies have stimulated industries to create false and untenable investments. These policies are followed by government corrective actions that destroy those same projects—waste the billions of dollars invested in them, and throw millions out of work. Business cycles are not an essential feature of market capitalism. They are the result of government interference with the market. In the misdirection of labor and the distortion of the structure of production during past business cycles, it was fairly easy to point to the places where the excessive expansion had occurred because it was, on the whole, confined to the capital goods industries... In contrast, the present expansion of money, which has been brought about partly by means of bank credit expansion and partly through budget deficits, has been the result of a deliberate policy, and has gone through somewhat different channels... I do not doubt that in a sense we have today the same kind of phenomenon, but the over-expansion, the undue increase of labor employed in particular occupations, is not confined to a single, clearly defined block such as the capital-goods industries. It is now spread much more widely, and the distribution is much more difficult to describe. It is a field I would wish some statistically minded economist would investigate in order to show how the process operated in particular countries. Friedrich A. Hayek  相似文献

We study market breakdown in a finance context under extreme adverse selection with and without competitive pricing. Adverse selection is extreme if for any price there are informed agent types with whom uninformed agents prefer not to trade. Market breakdown occurs when no trade is the only equilibrium outcome. We present a necessary and sufficient condition for market breakdown. If the condition holds, then trade is not viable. If the condition fails, then trade can occur under competitive pricing. There are environments in which the condition holds and others in which it fails.  相似文献

Price and Nonprice Competition with Endogenous Market Structure   总被引:2,自引:1,他引:2  
This paper examines the effect of the intensity of short-run price competition and other exogenous variables that affect gross profit margins—such as the degree of product differentiation and the consumers' responsiveness to quality—on market structure and on advertising and R&D expenditure. A key result is that more intense short-run competition can lead to lower concentration in industries with high advertising or R&D intensity, unlike exogenous-sunk-cost industries. Also, price competition has a negative effect on advertising or R&D expenditure. A case study is also presented, which is consistent with the theoretical results of the paper.  相似文献

Using a two-stage quantile regression framework, we uncover significant asymmetries across quantiles for all coefficients in an otherwise standard New Keynesian Phillips Curve (NKPC) for the euro area. A pure NKPC specification accurately captures inflation dynamics at high inflation quantiles.  相似文献

This article examines the relationship between investments and uncertainty for the US economy, as the latter is approximated by consumer sentiment, purchasing managers’ prospects and economic policy uncertainty. Contrary to the existing literature, we provide evidence that this relationship is time varying. The time variation is attributed to the observed temporal replacement effect between private and public investments. Furthermore, we show that there are two distinct correlation regimes in this relationship and unless we concentrate on them, we cannot fully unravel the real link between uncertainty and investments. Finally, we examine whether the use of the two correlation regimes provides better forecasts for investments compared to the use of the uncertainty indices alone. The forecasting exercise reveals that the use of correlation regimes provides statistically superior out-of-sample forecasts.  相似文献

International benchmarking has played a key role in the reform of Australia's infrastructure industries by promoting indirect or yardstick competition, in highlighting the need for further reform and building a consensus for implementing necessary changes. The international benchmarking of infrastructure performance by the Bureau of Industry Economics (BIE) between 1991 and 1996 did much to focus attention on the need for change. The BIE examined the performance of eight infrastructure industries relative to international best practice: electricity, rail freight, telecommunications, the waterfront, road freight, coastal shipping, aviation and gas supply. Performance comparisons concentrated on indicators of price, service quality, labour productivity and capital productivity. This paper reviews and summarises the performance comparisons the BIE undertook over the last three years of its infrastructure benchmarking program. The BIE international benchmarking program provides a useful role model for other countries wanting to seriously pursue reform of their infrastructure industries.  相似文献
