In this paper we develop a vintage model to gain a better understanding of the semiconductor industry and its role in recent U.S. productivity gains. Unlike previous work, in our model the observed price declines of individual chips are driven by the introduction of better vintages rather than by learning economies. Dominated chips, nonetheless, continue to be produced, for a time, due to sunk investments in chip‐specific production equipment. The model lends partial support to Jorgenson's hypothesis that an exogenous increase in Moore's Law could have generated the more rapid price declines, and faster productivity growth, seen after 1995.  相似文献

This article analyzes the impact and effectiveness of the Mexicanlabor retraining program for unemployed and displaced workers—Programade Becas de Capacitación para Trabajadores (PROBECAT).The strategy followed is to compare the post-training labormarket experiences of trainees with those of a comparison group—amatched sample of unemployed individuals who were eligible for,but did not participate in, PROBECAT. The results of this exercisesuggest that participation in PROBECAT reduced the mean durationof unemployment for both men and women trainees and increasedthe monthly earnings of men, but not of women. The results alsoindicate that the post-training earnings effect varied systematicallyby level of education attained, with the largest earnings increases(of about 28 to 37 percent) found for men with six to twelveyears of education.  相似文献

This study analyses the impact of OBS on banking productivity growth using a sample of 712 banks from 84 countries between 1999 and 2006. Our international setting allows us to analyse differences on the performance on banking institutions among various groups of countries with different economic and financial innovations development. We estimate cost and profit productivity growth using a parametric approach that decomposes the change in risk-adjusted cost and profit performance into two main components: changes in business conditions and changes in productivity. The latter one is decomposed further into the change in best practice and change in (in)efficiency.  相似文献

This study examines the influence of perceived risk on entrepreneurial desirability and feasibility as determining factors in the intention to start a self-owned business. Specifically, a multidimensional approach is taken to examine the different types of risks associated with entrepreneurship: economic, social, time, health and personal risks. The results obtained from a sample of 376 new entrepreneurs in Mexico confirm the fact that the perceived desirability and feasibility have a significant and positive effect on the intentions to start their own company. On one hand, the empirical evidence obtained shows a heterogenic effect of the risk dimensions associated with entrepreneurship on the perceived desirability and feasibility in their behaviour. Therefore, it was found that the economic risk associated with entrepreneurship has a negative effect on the feasibility to start a business, but does not significantly influence the desirability of that behaviour. On the other hand, a significant effect from the risk related to health is not seen on desirability and feasibility, but the negative influence of personal risk is empirically supported for both variables. Finally, the results obtained related to social and time risk are contradictory. Social risk negatively influences entrepreneurship desirability, but a positive effect is observed on the feasibility to create a business. For its part, the empirical evidence obtained does not support any effect of the time risk on the perceived feasibility of starting a business, but there is a positive on entrepreneurship desirability. These results, which are contrary to the traditional concept of risk as a barrier to entrepreneurship, are justified by the vocational nature of this behaviour and by the social sacrifices that are sometimes necessary to be able to make a business work.  相似文献

We analyse the evolution of mortality rates in Spain by age and gender between 1990 and 2018. We compare municipalities, ranked by socio‐economic status (SES) and grouped into bins of similar population size, to study changes not only in levels but also in inequality in mortality across the SES spectrum. We document large decreases in mortality rates throughout the period for all age groups, including children, even after 2000, and continuing after the Great Recession. These declines are stronger for boys and men, who had higher mortality rates to begin with. We find that inequality in mortality across municipalities was low among the young by 2018, while it was higher among adult men and older women. Inequality in fact increased over the period for older men. We explore the role of different causes of death and find that this increase in inequality is driven by stronger improvements in cancer‐related mortality among men living in richer areas. These improvements are not found among women, given their increases in mortality due to lung cancer.  相似文献

Knowledge is considered an essential resource in a company’s internationalization process, both from the sequential point of view and from the perspective of International Entrepreneurship. This paper proposes a model to integrate the influence of knowledge on international behavior based on proposals taken from the literature on organizational learning in multinational companies. The model comprises several phases: prior knowledge; acquisition of new knowledge; integration of both sets of knowledge; action and feedback. Using the proposed model, different courses of action are identified for further research into the process of company internationalization.  相似文献

This article examines the determinants of R&D collaboration of service firms. Different from manufacturing firms, we expect that types of innovation, public financing, innovation protection, purchase of external R&D, firm’s absorptive capacity, spillovers, and certain innovation barriers determine the firm’s decision to collaborate in R&D. Results indicate that firms that undertake R&D collaboration tend to undertake process innovation, receive public funding, can protect their innovations, and typically subcontract the development of their technologies. The article provides implications for theory and practice.  相似文献

This critical case study looks at the campaign led by Citizens UK and Unison to get the University of East London (UEL) to sign up to the London living wage (LLW). UEL agreed to pay the LLW after a brief campaign in November 2010 and it was subsequently implemented in August 2011. The study charts the course of the campaign and draws on mobilisation theory and new primary research to account for its success. What our findings suggest is that community organisers and union activists were able to organise and mobilise a largely apolitical group of migrant workers. This, we suggest, can be explained by the successful mobilisation of the community and augurs well for future broad‐based campaigns.  相似文献

Drawing on the contextual perspective, this study provides novel empirical evidence on how the organisational context (specifically, the firm's human resource strategy) has an effect on employee proactivity. We use matched data from managers and employees in 102 Spanish professional service firms to examine how high performance work systems contribute to enhance employee proactive behaviours through two motivational variables: role breadth self‐efficacy and flexible role orientation. Results of a multilevel study demonstrate that role breadth self‐efficacy mediates between HPWS and employee proactivity, but flexible role orientation does not mediate this relationship.  相似文献

The manufacturer's requirement of increasing productivity results in the need to design work stations that are increasingly more effective and specialized. However, this procedure can bring about an overloading of the worker, a lack of motivation, and, consequently, a reduction in productivity.Ergonomics adapts the work station to the worker with the object of improving his welfare and satisfaction at his post. One aspect that this science concerns itself with is the evaluation of physical demands connected to productive tasks. Mechanical movements are also studied in order to perform tasks efficiently.We here propose a new method of physical demand analysis that determines the risk factor for muscular skeletal lesion. This method uses, as a base, the system of predetermined times, MTM-UAS. It includes a computer system that allows us to easily analyse the operations at a work station and generates charts similar to those of UAS, but, instead of times, it measures the quantity of mechanical work necessary for each movement.The information that the method provides can be used by different divisions within companies in making decisions about improvements at work stations.  相似文献
