This Paper uses a two-period Von Stackelberg model to study the effects of profit taxation on the behaviour of a monopolist, when the entry of a potential competitor is threatened. A barrier to entry, consisting of a sunk cost, is assumed. If the potential competitor decides to enter, thus making a loss, deduction is allowed in the following period. This model shows that these tax deductions can make profit taxation be distortive.  相似文献

Foreign investment decisions of firms are often characterized by investment irreversibility, uncertainty, and the ability to choose the optimal timing of foreign investments. We embed these characteristics into a real option theory framework to analyze international competition among countries to attract mobile investments when firms, after the investment is sunk, can shift profit to low tax countries by transfer pricing. We find that an increase in the uncertainty of profit income reduces the equilibrium tax rates, whilst lower investment costs or larger profits, counteracts the negative fiscal externality of tax competition leading to higher equilibrium tax rates.

The aim of this study was to evaluate the combined influence of several lifestyle, health and housing factors in the occurrence of home injuries (HIs) among the elderly. The subjects were recruited from 10 hospitals in Rome, Italy. This study is a paired case-control study. Cases included subjects, aged 65-85 years, who visited the Emergency Department for an HI and were subsequently hospitalised (15 September 2004-30 June 2005). Controls were the subjects of the same gender, age (±3 years) and area of residence of cases. A conditional logistic regression model was used for analysing the variables obtained. In this study, we enrolled 107 hospitalised cases. It was found that the living room was the place where 33% of the accidents occurred. Eighty-seven per cent of the accidents were falls, and 33% of the accidents were the immediate consequence of sudden malaise. One-half of the cases reported one or more leg fractures. The variables that were independently associated with HI were poor household illumination, poor emotional status, regular physical activities and housekeeping activities. We conclude that this study shows the areas of intervention to target HI prevention activities.  相似文献

Innovation is a collective process that entails the coordination of distributed knowledge across diverse organizations. Technology infrastructures provide innovation systems with governance mechanisms to create and sustain complementarities across otherwise dispersed competences. The paper presents innovation platforms as a specific case of technology infrastructure. Operating strategically at the interface between the public and the private sectors, platforms enable capacity- and capability-building for individuals, teams and organizations. Illustrative evidence on innovation platforms in the United Kingdom and Italy confirms the importance of institutional responsiveness to stimulate variety and ensure coordination in the context of collective innovation processes.  相似文献

Technological knowledge can be understood as a collective good only when its production requires the absorption and integration of external knowledge. Such external knowledge is the outcome of R&D investments that cannot be fully appropriated by firms and generate spillovers. The exploitation of such knowledge spillovers requires specific investments in knowledge communication and absorption, which brings about specific costs. These costs are affected by the structural and dynamic characteristics of technological systems in terms of the knowledge base, the variety of actors and the communication infrastructures and processes. This paper analyzes the costs of collective knowledge production and their implications for the way in which the firm chooses the mix of internal and external knowledge. This choice in turn shapes the evolution of technological systems.  相似文献

In his Theory of Economic Development, Schumpeter introduced the distinction between different innovation types. Since then, a variety of studies have addressed this topic. However, despite of the recognised significance of more de-verticalised organisational forms in shaping and directing firms' innovative performance, no attempt has been made, as far as our knowledge is concerned, to investigate whether these practices are linked to the introduction of specific innovation types. The aim of the study is to fill this gap by investigating the impact of de-verticalised forms of labour organisational practices, different modes of organising research and development activity and the nature of employees' competences on the likelihood of introducing different types of innovations, controlling for firm's size and sectoral specificities. The results obtained on a sample of 199 firms located in Reggio Emilia province in Italy confirm that innovation development is a heterogeneous activity. The empirical evidence gathered also shows that foreign and domestic firms do not differ, to some extent, in the introduction of different kinds of innovations. However, being foreign or domestic is a discriminating factor in the introduction of innovations stimulating labour organisational developments.  相似文献

We study the emergence of strategic behavior in double auctions with an equal number of buyers and sellers, under the distinct assumptions that orders are cleared simultaneously or asynchronously. The evolution of strategic behavior is modeled as a learning process driven by a genetic algorithm. We find that, as the size of the market grows, allocative inefficiency tends to zero and performance converges to the competitive outcome, regardless of the order-clearing rule. The main result concerns the evolution of strategic behavior as the size of the market gets larger. Under simultaneous order-clearing, only marginal traders learn to be price takers and make offers equal to their valuations/costs. Under asynchronous order-clearing, all intramarginal traders learn to be price makers and make offers equal to the competitive equilibrium price. The nature of the order-clearing rule affects in a fundamental way what kind of strategic behavior we should expect to emerge.  相似文献

Unlike previous literature, we construct a hedonic model of wine price that incorporates all the main categories of variables simultaneously to enable a better evaluation of their importance on wine price formation. A comprehensive model has the advantage of providing more reliable estimates of the attributes' implicit prices thereby facilitating firms' pricing and improving effectiveness of wine production and marketing decisions. We utilize two different datasets of Sicilian wines collecting data from influential wine guides. Our results suggest that wine price strongly depends on objective features such as vintage, alcoholic content, geographical origin, grape variety, producer size and cellaring potential. In addition, use of containers like tonneaux and barrique positively affects prices, whereas use of concrete containers has a negative influence. No univocal indications emerge with regard to the effect of the type of company, type of viticulture and firm age. As for sensorial characteristics, our analysis provides novel evidence of the importance of olfactory variables such as aroma intensity and the presence of particular smells in the wine. Finally, current guides’ grades and firm reputation play a crucial role in determining wine prices as well.  相似文献

Inequality of opportunity is defined as the difference in individuals’ outcome systematically correlated with morally irrelevant pre-determined circumstances, such as ethnicity, socio-economic background, area of birth. This definition has been extensively studied by economists on the assumption that, in addition to being normatively undesirable, it can be related to low potentials for growth. However, empirical estimations of inequality of opportunity require accessing rich data sources, rarely available in poorer countries. In this paper, we exploit 13 consumption household surveys to evaluate inequality of opportunity in 10 Sub-Saharan African countries. According to our results, the portion of total inequality that can be attributed to exogenous circumstances is between 40% and 56% for the generality of countries. Our estimates are significantly higher than what has been found by previous studies. We detect a positive association between total consumption inequality and inequality of opportunity, and we study the different sources of unequal opportunities. The place of birth and the education of the father appear to exert the most relevant role in shaping inequality of opportunity in the region.  相似文献

Carbon reduction programs and corporate emissions reporting have expanded rapidly across firms in response to climate change and global warming. This development is partly driven by institutional demands and partly by value creation considerations. The consequences of these developments for management accounting and control (MAC) are not clear, despite anecdotal evidence that suggests an increasing effort to incorporate carbon accounting into traditional decision and reporting processes. The reasons for this lack of clarity are the disproportionate focus in practice on carbon disclosure, compared to a small number of empirical studies, and the absence of an academic debate in this novel area from a MAC perspective. This paper seeks to stimulate such an academic debate by reviewing the extant literature, identifying key theoretical and empirical shortcomings of extant academic research, and outlining some directions for future studies on carbon accounting. These directions are inspired by more established MAC research that may help to guide and organize MAC research in the emerging and exciting field of carbon accounting.  相似文献
