We study the impact of regulatory barriers to entry on workplace training. We develop a model of training in imperfectly competitive product and labour markets. The model indicates that there are two contrasting effects of deregulation on training. As stressed in the literature, with a given number of firms, deregulation reduces the size of rents per unit of output that firms can reap by training their employees. Yet, the number of firms increases following deregulation, thereby raising output and profit gains from training and improving investment incentives. The latter effect prevails. In line with the predictions of the theoretical model, we find that the substantial deregulation in the 1990s of heavily regulated European industries (energy, transport and communication) increased training incidence.  相似文献

Abstract. The paper proposes a panel cointegration analysis of the joint development of government expenditure and economic growth in 23 Organization Economic Cooperation and Development countries. The empirical evidence provides indication of a structural positive correlation between public spending and per‐capita gross domestic product (GDP), which is consistent with the so‐called Wagner's law. A long‐run elasticity larger than 1 suggests a more than proportional increase of government expenditure with respect to economic activity. In addition, according to the spirit of the law, we found that the correlation is usually higher in countries with lower per‐capita GDP, suggesting that the catching‐up period is characterized by a stronger development of government activities with respect to economies in a more advanced state of development.  相似文献

The labour productivity impact of innovation is investigated in this paper combining neo-Schumpeterian insights on the variety of innovation with the importance of industrial structures and firm size; two models are proposed for explaining productivity and export success in European manufacturing industries and firm-size classes. The empirical estimates are based on data from the European innovation survey (CIS 2), covering Austria, France, Italy, the Netherlands, and the UK, broken down by 22 sectors and for large, medium, and small firms. The econometric results, obtained adopting cross-sectional estimation methodologies able to account for unobserved industrial characteristics, show that productivity in Europe relies on product and process innovation, with the support of the efficiency gains provided by grouped business structures. Conversely, in Italy the introduction of new machinery linked to innovation appears as the key mechanism supporting domestic productivity. When export success is considered, all countries have to rely on an innovation-based model of competitiveness.  相似文献

This paper raises questions concerning the complexity of the term “community” when dealing with community-based tourism initiatives. It highlights the difficulty of translating into practice the paradigm of “community-based tourism”. Through a case study of tourism in the multi-ethnic village of Viscri, Romania, the paper discusses the operational role that a network of both internal and external actors may play in piloting tourism initiatives that produce benefits for communities that are unaccustomed to participatory development processes due to various barriers. The study highlights the key role played by a local leader and an external foundation in building a network that, thanks to the bonding and bridging relations activated, led the community towards a form of sustainable tourism development and a broader amelioration of the social conditions. The network described can be replicated in other geographical contexts, provided there is strong local leadership and also international interests and donors. In the long term, however, the network needs to be strengthened by involving other actors, above all local authorities. They are needed to assure the basis for long-term empowerment, participation in decision-making and progressive diversification of economic activities.  相似文献

Review of extant research on the corporate environmental performance (CEP) and corporate financial performance (CFP) link generally demonstrates a positive relationship. However, some arguments and empirical results have demonstrated otherwise. As a result, researchers have called for a contingency approach to this research stream, which moves beyond the basic question “does it pay to be green?” and instead asks “when does it pay to be green?” In answering this call, we provide a meta-analytic review of CEP–CFP literature in which we identify potential moderators to the CEP–CFP relationship including environmental performance type (e.g., reactive vs. proactive performance), firm characteristics (e.g., large vs. small firms), and methodological issues (e.g., self-report measures). By analyzing these contingencies, this study attempts to provide a basis on which to draw conclusions regarding some inconsistencies and debates in the CEP–CFP research. Some of the results of the moderator analysis suggest that small firms benefit from environmental performance as much or more than large firms, US firms seem to benefit more than international counterparts, and environmental performance seems to have the strongest influence on market-measures of financial performance.  相似文献

Retailing and media platforms recommend two types of items to their users: sponsored items that generate ad revenue and nonsponsored ones that do not. The platform selects sponsored items to maximize ad revenue, often through programmatic auctions, and nonsponsored items to maximize user utility with a recommender system (RS). We develop a binary integer programming model to allocate sponsored recommendations considering dual objectives of maximizing ad revenue and user utility. We propose an algorithm to solve it in a computationally efficient way. Our method is a form of postfiltering to a traditional RS, making it widely applicable in two-sided markets. We apply the algorithm to data from an online grocery retailer and show that user utility for the recommended items can be improved while reducing ad revenue by a small amount. This multiobjective approach unifies programmatic advertising and RS and opens a new frontier for advertising and RS research. We provide an extended discussion of future research topics.  相似文献

Risk assessment has struggled to reconcile public views and opinion with the results of science-based objective assessment. In this paper, we attempt to tease apart subjective and objective considerations that risk management decisions entail. Through the use of examples from the New Zealand Environmental Risk Management Authority, we argue that risk managers need to use quantitative tools in order to develop an objective understanding of the biophysical outcomes of an activity. Decision-making should then enter a phase where democratic methods are used to allow people to weigh these physical outcomes subjectively. We believe allowing subjective democratic decisions, based on objective reality, will help enable risk management to bridge gaps between practitioners and the public.  相似文献

We consider a Constant Elasticity of Variance (CEV) model for the asset price of a defaultable asset showing the so-called leverage effect (high volatility when the asset price is low). We show that a VaR constraint re-evaluated over time induces an agent more risk averse than a logarithmic utility to take more risk than in the unconstrained setting.  相似文献

This paper investigates the effects of labour market deregulation on demand, productivity and employment levels in the short term. The focus will be on deregulation of labour contracts, i.e. on the transition from a legal system that guarantees permanent employment to a system of formal rules allowing for job insecurity. The idea is that the greater the deregulation of labour contracts, the higher the productivity and the lower the demand and employment levels.  相似文献

A guest‐worker program provides an appealing way of addressing labor shortages in an advanced country. It requires, however, that foreign workers are willing to return home when their work permit expires. I examine how immigration policies, enforcement measures, and opportunities available in various markets at home and abroad affect the behavior of program participants. Welfare of a migrant who obeys the rules of the program is compared with that of workers who choose other options in order to define the conditions under which temporary migration is attractive to potential migrants and at the same time consistent with voluntary return.  相似文献
