Research by the Bureau of Labor Statistics does not support the view that present trends in the workplace will have negative effects on future productivity, wages, and job creation. The shift towards a service-producing economy will not necessarily result in generally lower productivity levels, slower rates of growth, and lower wage levels, as commonly believed. Further demographic changes may bode well for productivity; the future work force will have a higher proportion in the most stable and productive years. Although there will continue to be serious problems of high unemployment for some groups and job loss due to new technologies, gloomy predictions of a huge labor surplus and a trend towards low-paying jobs are unwarranted.  相似文献

The disaggregated structure of input–output (IO) analysis makes it very attractive in analyzing technical change. Various authors have applied IO models in comparative static experiments to measure the effects of observed technical changes in individual industries on economy-wide total output (or related primary input) requirements. Less often have researchers performed similar analyses on the effects of changes across all consuming industries in the productive consumption of a sector's output, because of the need to append an external analysis of substitution. Despite the obstacles to joint analyses of sectoral production and cross-sectoral consumption change, its appeal has long been recognized. In this paper, an anomaly in such analyses is presented: the sum of the separate effects of changes in production and changes in productive consumption does not equal the effects of the joint change. A comparative static exercise reveals the root cause of the anomaly: essentially, an index number problem. Empirical analyses are performed across a comprehensive set of US sectors to estimate the range of discrepancies.  相似文献

The problem of private under-investment in innovation: A policy mind map   总被引:1,自引:0,他引:1  
Michael Peneder   《Technovation》2008,28(8):518-530
This paper reviews the major finance-related causes of private under-investment in innovation and the consequent alternative choices for public policy. The focus is on (i) incentive-based arguments that address the problem of limited appropriability of new knowledge, and (ii) the lacking access to external sources of finance caused by imperfections in the capital market. Drawing a policy mind map, which aims to enhance the mutual awareness and coordination of policy makers at the crossroads of technology and corporate finance, the paper is organised along the following chain of thought: (i) causes and rationales, (ii) aims and targets, (iii) critical constraints, and (iv) the main finance-related instruments of innovation policy.  相似文献

Technological change and factor bias in the Indian power sector are analyzed using a translog cost function. Various components of technological progress and factor bias are identified and estimated, using a 21 year unbalanced panel data of Indian states and union territories. Heterogeneity across states is incorporated in the model using a variance component model. Appropriate corrections are made for unbalanced panel data. Empirical results show that the annual average rate of technological progress has been 2.4% for the country as a whole. Accumulation of knowledge and increasing scale are found to be the major factors contributing to technological progress. In contrast, the effects of factor price changes and fixed capital accumulation on technological progress have been unfavorable. Pure factor bias measure indicate saving in the use of fuel and labor, and increased use of materials. Tests are performed to check the curvature properties of the underlying technology.  相似文献

We analyze how a set of determinants affect trade among European countries over the period 1992–2008. The factors encompass variables from the areas of geography, culture, institutions, infrastructure, and trade direction. Trade is analyzed for four types of goods: primary goods, parts and components, capital goods, and consumer goods. For each type of good we also distinguish its definition in terms of flows, intensive margin, and extensive margin. Methodologically, we first derive country-pair fixed effects over all possible pairs of export–import partners, and in the second stage we relate fixed effects with a set of influential factors. We show (i) the intuitive and varying effects of geographical, cultural, and institutional factors; (ii) the beneficial effects of soft and hard infrastructure; and (iii) the key importance of trade between old and new EU members.  相似文献

We extend an earlier model of innovation dynamics based on percolation by adding endogenous R&D search by economically motivated firms. The {0, 1} seeding of the technology lattice is now replaced by draws from a lognormal distribution for technology ‘difficulty’. Firms are rewarded for successful innovations by increases in their R&D budget. We compare two regimes. In the first, firms are fixed in a region of technology space. In the second, they can change their location by myopically comparing progress in their local neighborhoods and probabilistically moving to the region with the highest recent progress. We call this the moving or self-organizational regime (SO). The SO regime always outperforms the fixed one, but its performance is a complex function of the ‘rationality’ of firm search (in terms of search radius and speed of movement). The clustering of firms in the SO regime grows rapidly and then fluctuates in a complex way around a high value that increases with the search radius. We also investigate the size distributions of the innovations generated in each regime. In the fixed one, the distribution is approximately lognormal and certainly not fat tailed. In the SO regime, the distributions are radically different. They are much more highly right skewed and show scaling over at least 2 decades with a slope around one, for a wide range of parameter settings. Thus we argue that firm self-organization leads to self-organized criticality. The online version of the original article can be found under doi:.  相似文献

Drawing on technical change and institutional theories, this paper examines the convergence and divergence of job discretion between occupations and institutional regimes in Europe from 1995–2010. Latent growth modelling of a pseudo‐panel data set derived from the European Working Conditions Survey reveals that significantly different rates of change have led to an increasing polarization of job discretion between occupations and between Nordic and other European countries. Across occupations the findings are in keeping with routine‐biased technical change rather than skill‐biased technical change theories and suggest that the effects of technical change on job discretion depend largely on whether technology substitutes or complements job tasks. Across countries, the results are in line with employment regime theory, which suggests that institutional differences (particularly employment policies and trade union influence) are driving cross‐national variation in job discretion. Overall, a more comprehensive empirical and theoretical understanding is provided of factors shaping change in a key aspect of job quality, namely job discretion.  相似文献

There is increasing recognition that the transfer of foreign technology to developing countries should be considered in light of broader processes of learning, technological capability, formation and industrial development. Previous studies that have looked at this in the context of cleantech industries in emerging economies tend to overlook firm-level specifics. This paper contributes to filling this gap by utilising in-depth qualitative firm-level data to analyse the extent to which the use of different learning mechanisms can explain differences in the accumulation of technological capabilities. This is explored via an examination of eight firms in the biomass power equipment industry in Malaysia during the period 1970–2011. The paper finds that firms relying on a combination of learning from foreign technology partners and internal learning by planned experimentation make most progress in terms of technological capability. Nevertheless, local spill-over effects were found to be important for some firms who learned principally from imitation of local competitors, although significantly, firms learning from local spillovers failed to advance beyond extra basic operating technological capabilities. Those firms who proactively pursued learning from foreign partners, on the other hand, advanced further, reaching basic innovative levels of technological capabilities. These findings are relevant for a wider range of industrial sectors in emerging economies.  相似文献

区域经济一体化是当前世界发展中的一个重要趋势。在探讨东亚经济一体化这一问题上,回顾欧洲一体化走过的道路无疑会给我们带来很多启示。针对东亚经济合作目前所呈现出来的多元化模式,我们不难看出,东亚经济一体化的发展瓶颈在于各国关系的有效处理和各国利益的合理分配。总之,从欧洲一体化的历程看东亚经济一体化,更应该确立合作的理念。同时,东亚经济一体化也可以借鉴欧洲经济一体化的经验,用具有约束力的条约机制去巩固每一个一体化成果。  相似文献

This paper studies variables that have an effect on the choice of whether or not reports on corporate social responsibility are assured and who is selected to provide assurance. Such assurance reports increase the credibility of environmental and social reporting. In a European sample we observe some differences from previous research. Overall, industry effects seem small, but size and media visibility have a significant impact on assuring CSR reports. It seems that companies differentiate less between auditors and consultants.

This paper investigates the possibility of a long-run relationship between the Economic Freedom Index (EFI), Foreign Direct Investment (FDI) and value added components of GDP in thirty Eastern, Central and Western European countries. The study further examines whether the FDI and sector-specific components of GDP have any significant impact on economic freedom for these countries. We use annual data and employ Pedroni and KAO panel cointegration analyses to assess the long-run relationships. The results indicate that there is a significant long-run relationship between the variables under study. Moreover, the evidence shows that the service and industry value added components positively affect EFI, while the agriculture value added component has a negative effect on EFI. However, contrary to the prior literature, we observe a marginally significant and negative relationship between EFI and FDI in the random effects model.  相似文献
