This article estimates two unobserved components models to explore the macrodynamics of entrepreneurship in Spain and the USA. We ask whether entrepreneurship exhibits hysteresis, defined as a macrodynamic structure in which the cyclical component of entrepreneurship has persistent effects on the natural rate of entrepreneurship. We find evidence of hysteresis in Spain, but not the USA, while in Spain business cycle output variations significantly affect future rates of entrepreneurship. The article discusses implications of the findings for the design of entrepreneurship policies.  相似文献

Many countries since 1990 have adopted semi-presidential constitutions, which are often considered to be problematic, primarily because of the potential for conflict between the assembly-supported government and the popularly elected president. Such conflicts are said to lead to unstable governments, policy paralysis and the eventual undermining of the democratic regime. Using data for all parliamentary and semi-presidential democracies between 1946 and 2006, we examine the effect of semi-presidential constitutions on the duration of prime ministers’ tenure in office, government accountability with respect to economic outcomes, and democratic survival. We also examine (for a smaller sample of post-communist countries) the impact of these constitutions on the progress of structural reforms. We find that the observed higher instability of prime ministers in semi-presidential democracies is more due to the electoral system than to the presence of a popularly elected president. We also find that semi-presidential constitutions have little impact on the government’s accountability to economic outcomes and on the survival of democratic regimes. Finally, we find that neither a weak president nor a weak government is optimal for the progress of economic reforms in post-communist countries. Regarding economic reforms, the optimal allocation of constitutional powers between the president and the government grants both significant powers.  相似文献

Scientific and technological policy has become a key activity in contemporary societies. In this context we present different projections about the evolution of science and technology in the area of robotics and advanced automation, which in turn shapes the new possibilities and risks emerging in this area in the future. This goes hand-in-hand with an analysis of the interaction of such trajectories with the social context from which they emanate. This interaction reinforces the need for establishing the probable sequence of technological innovation; analysing the impacts on economy and society; and providing qualified information for decision-making, both in policy and business. In this article, we present the results of the prospective research carried out in the field of robotics and advanced automation, paying special attention to the transformation trends of organizations, and the integration of robots in daily life and leisure, and underscoring potential repercussions which may deserve more attention and further research.  相似文献

Recent theoretical and empirical work indicates that management control systems (MCS) are an important element in enhancing innovation. We extend this research thrust examining the adoption of MCS in product development, arguably one of the business processes where innovation plays a major role. Using a sample of 69 early-stage entrepreneurial companies, data are collected from questionnaires and interviews with each of the CEO, financial officer, and business development managers pertaining to product development MCS. We examine seven different systems: project milestones, reports comparing actual progress to plan, budget for development projects, project selection process, product portfolio roadmap, product concept testing process, and project team composition guidelines. We address three distinct questions: (1) What are the reasons-for-adoption of these systems? The nature of our sample allows us to trace back to the adoption point and develop a set of reasons-for-adoption from the analysis of the data. While MCS fulfill certain roles as described in the literature, these reasons-for-adoption are distinct from these roles. Results indicate that certain events lead managers to adopt these systems and address the challenges that they face. They include contracting and legitimizing the process with external parties and internal reasons-for-adoption such as managers’ background, learning by doing, need to focus the organization, or reaction to problems. (2) Are these reasons-for-adoption associated with differences across companies in the time from their founding date until these systems are adopted (time-to-adoption)? Prior research has looked at the covariance of various organizational variables with this timing; this study goes a step further by looking at the effect of different reasons-for-adoption on this timing. Our evidence finds an association between these two variables. (3) Are these reasons-for-adoption relevant to performance? We find that the reason-for-adoption is associated with the on-time dimension of product development performance.  相似文献

After a report of results about infinite servers queues, essentially on its busy period, a model is built, using networks of queues with infinite servers in each node, to study a two echelons repair system for example of a fleet of aircraft, shipping or trucks. The customers are the failures, and their service time is the time that goes from the instant at which they occur till they are completely repaired. The failing repairs occur in a base or in a remote station. The whole failures detected in the base are repaired there. Some of the failures detected in the station are repaired there and the others in the base. The results referred above allow the determination of a two echelons repair system performance measures. In this application, models of Carrillo (1991) and Ferreira (1996) are considered, improved and completed. The theory is illustrated with a numerical example.  相似文献

Recent research on corporate social responsibility (CSR) suggests the need for further exploration into the relationship between small and medium-sized enterprises (SMEs) and CSR. SMEs rarely use the language of CSR to describe their activities, but informal CSR strategies play a large part in them. The goal of this article is to investigate whether differences exist between the formal and informal CSR strategies through which firms manage relations with and the claims of their stakeholders. In this context, formal CSR strategies seem to characterize large firms while informal CSR strategies prevail among micro, small, and medium-sized enterprises. We use a sample of 3,626 Italian firms to investigate our research questions. Based on a multi-stakeholder framework, the analysis provides evidence that small businesses’ use of CSR, involving strategies with an important impact on the bottom line, reflects an attempt to secure their license to operate in the communities; while large firms rarely make attempts to integrate their CSR strategies into explicit management systems.  相似文献

长期以来,美联储从本国利益出发制定经济监管政策,在美国和世界经济体系中创造了过量的信用,导致美元在全世界泛滥,美国人放弃储蓄,过度投资和消费;美国主体经济从制造业转向了非出口服务业;美国的债务,不管是从国家角度还是从个人角度都达到了前所未有的高度,这一切最终演变成了这次全球金融危机.对于中国这样的经济大国,一定要从中吸取教训,扬长避短,并建立科学发展的核心价值观.  相似文献

The public vocational education and training (VET) system is one of the few areas in Australia's tertiary education system where students are required to pay upfront fees without access to loan assistance. These arrangements may lead to sub‐optimal educational outcomes to the extent that prospective students reject a VET education on the basis of short‐term financial constraints. In this paper we analyse some of the important issues related to the adoption of FEE‐HELP (a 2005 federal government financial instrument based on the Higher Education Contribution Scheme (HECS)). It is argued that income contingent loans of this kind are associated with the advantages of both default‐protection and consumption smoothing. Using data from the first three waves of the Household Income and Labour Dynamics in Australia (HILDA) survey, we examine various empirical issues associated with the adoption of FEE‐HELP in VET, including the extent of private salary returns to VET qualifications. As well, we explore issues related to the public subsidies inherent in the adoption of FEE‐HELP in VET, and illustrate the time periods involved in loan repayments for various assumptions concerning the size of the charge and the future income of VET graduates. Administrative issues are considered, as are the implications for the Commonwealth government with respect to potential subsidies associated with the design parameters. In the 2007–08 Federal Budget, the former government announced a small extension of the FEE‐HELP system into Australian VET, a reform consistent with improved tertiary funding arrangements.  相似文献
