The literature can justify both increasing and decreasing marginal taxes (IMT & DMT) on top incomes under different welfare objectives and income distributions. Even when DMT are theoretically optimal, they are often politically infeasible. Then a flat tax seems to be a constrained optimal solution. We show however that, given any flat tax we can increase the total utility of a poor majority by raising the top income tax rate under a simple condition, which can be checked with empirical data. We further generalize our main results allowing different welfare weights, declining elasticity of labor supply and more tax bands. 相似文献

Many European governments still advocate a so-called ‘cultural exception’, intended to protect consumers and smaller bookshops,
to keep their book markets isolated from competition. Other countries, with similar aims in mind, have chosen liberalization
schemes instead. To reconcile these opposing views, this paper provides a theoretical framework to study the textbook market,
depicting it as dominated by two simultaneous forces: horizontal differentiation among booksellers and a vertical relationship
between publishers and bookshops. Using this model, we analyse the effects of alternative price schemes on the market structure
and how potential benefits from price liberalization are influenced by the number (and size of) booksellers. 相似文献

Britain is emerging uncertainly from recession. This essay looks at the character of the recession, the financial crisis that inaugurated it and the key issues that will dominate the recovery phase. In particular, it argues that the underlying and deeply entrenched political conditions which underpinned the crisis, notably bi-partisan encouragement of a ‘property-owning democracy’, show no signs of abating. Without such a change, a recurrence of the crisis appears highly likely. 相似文献

This opinion piece reviews and critiques the opinion piece by David Fennell which presents a proposal for a new article about the ethical treatment of animals to be added to the UNWTO Global Code of Ethics for the tourism industry. The case presented here rests on a detailed examination of the use of the concepts of speciesism and anthropocentrism in the original opinion piece. It finds that, while speciesism is currently a fashionable way to draw parallels between animals and humans, it is dependent on the evidence around the questions of sentience, cognition and consciousness. While there is increasing evidence for animal sentience and cognition, human consciousness is wholly different from that of even the most advanced animals. And, although anthropocentrism is a dominant idea in many forms of political decision making in general, it cannot be used as a stick with which to beat tourism scholarship: many writers on tourism adopt distinctly ecocentric lines of argument, including the concepts of ecotourism and sustainable tourism. The paper also notes that only ca. 30% of UNWTO's national members had given legal recognition to the existing code of ethics nearly 10 years after its ratification by the UN. 相似文献

The World Bank has suggested the need to enhance Information and Communication Technology skills in all sectors because a 10% increase in internet connectivity was found to boost GDP growth by 1.38%. Simultaneously, the OECD argued that high internet access rates generate a 2% increase in GDP. Because the internet positively affects economic growth, we investigated the relationship between an economically active population, human capital and technology to evaluate these effects in Mexico. A data series from 1991 to 2010 was analysed in three stages according to the least-squares method. A Cobb–Douglas function under the Solow model was considered. Technology and internet access were found to positively affect top-level students and graduate students and thus contribute to the global innovation index. 相似文献

The Philippine government intervenes in the domestic rice market through the imposition of import tariffs and the provision of producer and consumer subsidies. While policymakers are aware that these programmes come with allocative efficiency costs, they justify the programmes on the grounds that they insulate the domestic economy from unexpected price spikes in the international rice market. An interesting matter for policy evaluation is to quantify the insulation benefit that the programmes provide in circumstances of sudden severe import price spikes. To examine this question, we undertake a dynamic computable general equilibrium (CGE) simulation in which the Philippines is subject to an external rice price shock. We find that the insulation benefit of the support programmes under a 2008-like event is worth approximately 0.10% of real consumption. However, the cost of insuring against these price spikes is significant. We estimate the annual cost of the rice market interventions at approximately 0.40% of real consumption. 相似文献

The non-stationarity tests of Phillips-Perron (1988) (PP tests) suggest that Australian macroeconomic output possesses a stochastic rather than a deterministic log-linear trend. Kwiatkowski et al. (1991) argue that such tests have low power and propose the KPSS test, in which the null is stationary. However, the KPSS test results reinforce the PP findings for Australia. Cochrane (1988) variance ratio (VR) tests further suggest that there may be a very strong random-walk component in the Australian business cycle. Rappoport and Reichlin (1989), however, argue that all such tests are biased in favour of the stochastic trend alternative if there are trend breaks in the data. Following up on this point, the paper finds that, in Australia's case, the stochastic trend alternative is statistically dominated when the data are allowed to be characterized by a probabilistic, regime-switching, segmented trend specification. Therefore, to the extent that real business-cycle theories of the business cycle gain support from stochastic trends in real output, this latter piece of Australian evidence does not strengthen their case. 相似文献

Fundamentals of service science 总被引:7,自引:1,他引:6
Service systems are value-co-creation configurations of people, technology, value propositionsconnecting internal and external
service systems, and shared information (e.g., language, laws, measures, and methods). Service science is the study of service
systems, aiming to create a basis for systematicservice innovation. Service science combines organization and human understanding
with business andtechnological understanding to categorize and explain the many types of service systems that exist as wellas
how service systems interact and evolve to co-create value. The goal is to apply scientific understandingto advance our ability
to design, improve, and scale service systems. To make progress, we think servicedominantlogic provides just the right perspective,
vocabulary, and assumptions on which to build a theory ofservice systems, their configurations, and their modes of interaction.
Simply put, service-dominant logicmay be the philosophical foundation of service science, and the service system may be its
basic theoreticalconstruct.

The resource orchestration concept has attracted considerable interest in contemporary innovation research. However, resource orchestration is a manager‐centric framework and not all of its components necessarily reflect the value‐creation processes of organizations focusing on team‐based innovation. Drawing on a single‐case study of an innovative Swedish software company, we illustrate the roles of autonomous teams, customers, and top managers in orchestrating resources for team‐based innovation. Moreover, we introduce the concept of resource flocculation to describe how key actors co‐orchestrate various resource orchestration processes. The study contributes to research on resource orchestration by adapting the model to the conditions characterizing team‐based innovation, and to research on team‐based innovation by addressing how innovative teams are related to overall resource orchestration processes and, ultimately, organizational innovation outcomes. 相似文献

Nowadays, it has become clear that the capacity of organizations to innovate and manage their human resources can be sources of competitive advantage. Recently, literature also asserts a positive relationship between human resource management and innovation. However, very little empirical research has specifically addressed those relationships. Using structural equations modelling with data collected from 173 Spanish firms, this study analyses them. Our findings show that innovation contributes positively to business performance and that human resource management enhances innovation. Implications for both academics and managers as well as future research lines are discussed. 相似文献
