The performance of service industries in Canada has been lower than that of good industries over the last four decades, with noticeable exceptions such as for railways and telecommunication carriers. Service industries were less economically (and technically) efficient in that they generated less output value (quantity) per hour worked (level and growth) or per combined unit of labour and capital (multifactor productivity growth) than good industries. The relative output price of services declined slightly over time compared with goods. At the disaggregated level, changing relative output prices were substantial and proved to be an important factor explaining the relative satisfactory economic performance of many service industries despite their low technical performance. Nevertheless, the output share of service industries increased over that period, sustained, mainly, by the growing recourse of all firms to outsourcing of services.  相似文献

Supply chain management (SCM) is implemented by integrating corporate functions using business processes within and across companies. Several process‐oriented frameworks for SCM have been proposed but only two of these provide sufficient detail to enable implementation. We evaluate the Supply‐Chain Operations Reference (SCOR) framework and The Global Supply Chain Forum (GSCF) framework using four criteria and identify their relative strengths and weaknesses.  相似文献

Building on research by Akehurst et al. (Serv Ind J 32:2489–2505, 2012), this study analysed internal and external factors in women entrepreneurship and linked these factors to the barriers that women face when starting businesses. To do so, two contrasting statistical techniques were used: PLS and QCA. After analysing results from each of these techniques, we observed that family duties and difficulties in obtaining financing (both internal and external) were the main factors related to barriers faced by women entrepreneurs.  相似文献

Summary. Finding solutions to the Bellman equation often relies on restrictive boundedness assumptions. In this paper we develop a method of proof that allows to dispense with the assumption that returns are bounded from above. In applications our assumptions only imply that long run average (expected) growth is sufficiently discounted, in sharp contrast with classical assumptions either absolutely bounding growth or bounding each period (instead of long run) maximum (instead of average) growth. We discuss our work in relation to the literature and provide several examples.

While sustainable development is recognized as an essential requirement for achieving economic goals without degrading the environment, major problems arise in defining methods for formulating and implementing sustainable strategic actions at the macro‐level, including islands. Bearing in mind this limitation, this research paper will attempt to present a strategic planning methodology for drawing up strategic issues for tourism development from the point of view of sustainability, which is particularly appropriate to islands. The authors first review existing literature on sustainable development with a view to defining a conceptual approach to sustainability and identifying particular areas for sustainable tourism development in the island context. A methodology for formulating strategic issues for sustainable tourism development in Gran Canaria is then drawn up. Sociocultural aspects, the environment and the economy, with particular emphasis on tourism, are examined in order to identify major strategic issues for sustainable development in Gran Canaria.

This Special Issue (SI) gathers 13 papers presented at the 23rd INFER Annual Conference which took place in Lisbon, 8–10 September 2021, at ISEG – Lisbon School of Economics and Management. The conference was organised by INFER (International Network for Economic Research), UECE (Research Unit on Complexity and Economics), and REM (Research in Economics and Mathematics). The papers of the SI focus on key topics in international macroeconomics, revisit the fiscal policy conduct within a globalised world, investigate how uncertainty and risk affect macroeconomic policies, and analyse the links between labor market outcomes, automation, and economic integration.  相似文献

While many studies on the Fourth Industrial Revolution (FIR) focus on efficiency, productivity and economic progress, only a few have considered its ethical aspects. This article tries to contribute to filling this vacuum by providing a comprehensive approach to ethical risks at the workplace. Drawing upon Catholic social teaching (CST)—addressed to all people of good will—it analyzes ethical aspects at the workplace posited by the FIR, and more particularly by Industry 4.0, which is at the core of this revolution. CST emphasizes the dignity of the worker and the necessity to flourish at the workplace. While robots, artificial intelligence, and interconnected technologies are only instrumental, the real subject of work is the worker. This casts specific light on the ethical issues analyzed, including effects on employment, wages and inequality, human quality treatment, relational aspects, safety and health, surveillance on employees, and meaningful work.  相似文献

Observed autoignition events and extinguishing the resulting smouldering fires in an underground storage system of a coal-fired power plant have provided insight into the array of contributing variables, and some experience on quantifying the risk with alternative scenarios of event initiation, progress and potential mitigation. Although the first attempts to quantify the risk suggest high sensitivity to the sequence of action taken after fire alarm, and no similar storage sites really exist, some recommended preventive, corrective and other mitigating activities can be at least partly defined and improved by using the cumulative experience and parallel efforts in other closed or underground storage sites. However, there are also so-called black (or at least grey) swans: unexpected events for which the facility may be poorly prepared for. In the case of the underground storage silos, such an event was experienced when incoming cold coal during a harsh winter season froze the sewer system that normally protects the stored coal from seepage water. With blocked normal bypass, the seepage water found its way to the coal silos and created large clumps of icy coal that blocked the coal conveyors. Although freezing weather is not unusual at high-latitude power plants, the common methods to combat freezing of coal are mainly useful for open storage sites and above-ground transport. Options for mitigation are discussed, as well as the event chain leading to an event that had never previously occurred. The case is discussed from the point of view of options to prepare for rare or unforeseen events.  相似文献
