For the past four decades (1961-2000), the Malaysian economy grew at an impressive average rate of 6.8% per annum. The rapid growth has been attributed, in part, to the tremendous success in the export-oriented industrialization policy. Several empirical studies on export-led growth for Malaysia have, however, led to inconclusive and mixed results. This may be due to the exclusion of domestic demand in the bivariate or multivariate models used in the studies. This study re-examines the role of domestic demand in economic growth in Malaysia. Using a three-variable cointegration analysis, the study shows that there exist short run bilateral causalities among the three variables, which implies that both the export-led growth and domestic demand-generated growth hypotheses are at least valid in the short run. On the other hand, the results are not supportive of the export-led growth hypothesis in the long run. Instead, the highly significant positive impact of domestic expenditure on economic growth implies that use of domestic demand as the catalyst for growth is appropriate. 相似文献

This paper analyses quality discrimination when the monopolist provides two types of qualities for two-types of users, for example, in the software market. The users using software are confronted with two types of quality in using the software: one is related to learning, while the other is operation. In addition, the users are discriminated by the frequency of utilization for software, for example, low-demand and high-demand users. In this paper, the characteristics for bi-directional quality distortion in both learning quality and operation quality are analysed. It is shown that the distortion can occur both for low demanders and for high demanders. Finally, from public policy, a subsidy mechanism is introduced. 相似文献

Cooperation in several phases of the innovation process is viewed by antitrust authorities with suspicion. They face the dilemma between providing the right incentives for the appro-priability of returns to R&D and the risks of diminishing product market competition. The current legislation in the European Union and the United States gives special treatment to cooperation in R&D and the joint exploitation of results (extended cooperation). We study several collusive regimes for a class of examples in which vertical relations are explicitly introduced. Regarding antitrust policy implications we fmd that: a) there is an ana-lytical justification to a ‘rule of reason’ treatment for extended cooperation in research joint ventures and, b) individual exemptions, though restrictive of competition, might be welfare improving. 相似文献

Drawing upon the innovative milieux and industrial districts literature, the paper provides substantial empirical evidence that firms have a greater chance of being innovative if they co-operate with other firms over innovation, albeit undertaking no investment in RLD. This is an important result especially for small firms. In particular, the paper focuses on inter-firm cwperation along the supply chain, using a swey of firms in the West Midlands to investi-gate co-operation over innovation between suppliers and buyers. A probit model is used to test the link between innovation performance and four innovation inputs: R&D expenditure, R&D personnel, networking with suppliers and networking with client firms. 相似文献

East Asian development experience provides the basis for understanding which are the essential elements of effective technology strategy and policy, those that are required for the efficacious development of countries that have not yet embarked on a path of sustained modernization. Globalization has had a profound impact on development, enabling countries that could exploit its propelling forces to pursue a potent strategy of export-led economic and technological development. The policies needed to sustain this strategy are those required to foster institutions that permit effective commerce among economic agents, those necessary to generate the rapid accumulation of human and physical capital, and those essential to ensure that resources are allocated in accord with the economy's dynamic comparative advantage. Of crucial importance among the latter are effectively implemented policies of selective intervention designed to develop infant industries and to foster their fast-paced achievement of international competitiveness through rapid attainment of the requisite technological capabilities. 相似文献

This paper investigates the impact of R&D disclosure and finance variables on the level of R&D expenditures. The question addressed is: what is the impact of changes in disclosure requirements on the relationship between R&D expenditure and the financing of firms? The question is motivated by the possible signalling role that elective disclosure may have had prior to changes in accounting practices to ensure R&D disclosure. 相似文献

It is often argued that technical change is responsible for the increase in wage inequality in Britain and the United States in the 1980s and 1990s. In this paper we examine this argument using data from individuals and establishments. It is found that the presence of micro-electronic technologies in workplaces is associated with higher earnings, especially for skilled workers. Decompositions suggest that technical change could have been a cause of the increase in skills premium for highly skilled workers. Nevertheless, our view is that the correlation between wages and plant-level technology is mainly driven by the effect of high wages on the propensity to introduce new technologies rather than vice versa. This view is supported by simultaneous models of the wage-technology relationship. 相似文献

The purpose of the study is to characterize different styles of work organization in French firms and their current changes and to link them to the use of specific technologies and to firms performance. The data which are used arc of two kinds: a labor force survey (1 470 blue collar) and a business survey (7 089 firms). We show that two main variables create differences among firms' organization devices: the intensity of communication within the workshop and the level of autonomy of workers (facing technological and hierarchical constraints). The use of advanced technologies and the skill of the labor force are positively linked to both organizational variables. Therefore. ‘Communicating organization’ and organizational innovation seem to aim at creating conditions for individual and collective learning on new technologies. They also enhance the ability of the firm to adapt to changing market conditions through technological innovation and inventory reduction, These views are supported by econometric estimation. 相似文献

The impact of technological change upon gross investment has been relatively ignored. Building upon the foundations of the analysis of technological diffusion, an empirical model of gross investment is constructed that takes due account of technological change. This model is then tested upon a panel data set covering 185 UK firms over the period from 1984 to 1992. The results support the hypothesis that there are significant relationships of the expected signs between firm level gross investment, indicators of technological opportunity; the price of the capital goods that embody new technology, and firm and industry characteristics. There is also evidence of lagged adjustment effects in the investment process. 相似文献
