Decisions in Economics and Finance - In this paper, we consider the nonlinear discrete-time dynamic model proposed by Bischi and Baiardi (Chaos Solitons Fractals 79:145-156, 2015a). The model... 相似文献

The paper analyses the impact of tax evasion on government budgets, using a monetary circuit model. It is possible to show that, under specific parameter values, evading taxes on profit becomes an attractive proposition when government policies tax capital and employment in different ways and on different timescales. Without adequate tax enforcement, government is reduced to acting as a financial backer for companies. Furthermore, a lower tax rate on labour income enabling money to flow from households to companies through private consumption reduces incentives for tax evasion. These results hold true even if the government decides to implement a balanced budget fiscal policy. 相似文献

Business models (BMs) in high-tech industries are analysed from a dynamic point of view in the context of cultural goods. Despite the increased interest in BMs, there is still a gap in terms of the generally accepted definition and of how BMs are analysed within an integrated framework. The aim of this paper is twofold: to provide a theoretical framework to understand BMs and how they change over time, and an empirical investigation of the characteristics of firms that apply high technology to cultural goods (HTCGs). Having defined what an HTCG firm is, within- and cross-case analyses are carried out on 30 firms that operate in the field of the cultural goods in Tuscany (Italy). The results showed interesting patterns of evolution of BMs, thus providing useful insights into the unexplored field of HTCGs. 相似文献

This paper proposes the use of Bayesian model averaging (BMA) as an alternative tool to forecast GDP relative to simple bridge models and factor models. BMA is a computationally feasible method that allows us to explore the model space even in the presence of a large set of candidate predictors. We test the performance of BMA in now-casting by means of a recursive experiment for the euro area and the three largest countries. This method allows flexibility in selecting the information set month by month. We find that BMA-based forecasts produce smaller forecast errors than standard bridge model when forecasting GDP in Germany, France and Italy. At the same time, it also performs as well as medium-scale factor models when forecasting Eurozone GDP. 相似文献

The main purpose of this paper is to develop a conceptual framework for understanding the literature on the consequences of contemporary performance measurement (CPM) systems and the theories that explain these consequences. The framework is based on an in-depth review of 76 empirical studies published in high-quality academic journals in the areas of accounting, operations, and strategy. The framework classifies the consequences of CPM into three categories: people's behaviour, organizational capabilities, and performance consequences. This paper discusses our current knowledge on the impact of CPM, highlighting inconsistencies and gaps as well as providing direction for future research. 相似文献

This paper describes a dynamic stochastic general equilibrium model featuring a fraction of non-Ricardian agents in order to estimate the effects of fiscal policy in the Euro area. The model takes into account distortionary taxation on labor and capital income and on consumption, while expenditures are broken down into purchases of goods and services, compensation of public employees and transfers to households. A newly computed quarterly data set of fiscal variables is used. Our results point to the prevalence of mild Keynesian effects of public expenditures. In particular, although innovations in fiscal policy variables tend to be rather persistent, government purchases of goods and services and compensations for public employees have small and short-lived expansionary effects on private consumption, while innovations in transfers to households show a slightly more sizeable and lasting effect. The effects are more significant on the revenue side: decreases in labor income and consumption tax rates have sizeable effects on consumption and output, while a reduction in capital income tax favors investment and output in the medium run. Finally our estimates suggest that fiscal policy variables contribute little to the cyclical variability of the main macro variables. 相似文献

This paper investigates the importance that consumers assign to local network effects, i.e. the extent to which they take account of their contacts’ mobile operators when choosing a provider for themselves. The authors identify individual characteristics that affect the importance consumers attach to local network effects. The study relies on a survey of 193 Italian students. The results show that consumers are highly heterogeneous with respect to the importance they give to the operators chosen by their friends/family members in choosing which provider to use. This heterogeneity is associated with individual innovativeness and patterns of mobile phone usage. For instance, consumers who are more interested in local network effects are typically more-aware users, who use voice services quite intensively. These consumers, who pay attention to local network effects, spend comparatively little proportional to the intensity of their mobile usage. 相似文献

The level of science skills in Spanish students are significantly below the average of the Organisation for Economic Co-operation and Development, and university teachers agree that the level of freshmen students’ skills is too low. Moreover, the number of engineering enrollments has been declining in recent years. The purpose of this study is to improve both the level of knowledge and skills of students upon entrance into engineering programs and their general opinion about engineering studies. The aim is to establish the importance of proper coordination between groups involved in the overall educational process and to avoid, at least in part, the decline in recent engineering enrollments. The project had the following four phases: (1) determination of the freshmen’s weakest concepts; (2) assessment of high schools students’ knowledge; (3) development of educational activities; and (4) re-assessment of high school students. These measures were complemented with the high school teachers’ opinions about the students improvements and analyses of the evolution of engineering enrollments. Most of the participants significantly improved their knowledge and skills. Similarly, high school teachers believed that the attitude of the students toward engineering improved significantly. 相似文献

We use social network analysis to evaluate ‘behavioural’ additionality aspects of public programmes supporting research and development (R&D). The paper appraises empirically the partnership and knowledge networks created around the R&D activities of the Information Society Priority of the Sixth Research Framework Programme of the European Community. These emergent, scale-free networks are found to play an important role in generating and, especially, in diffusing knowledge by attracting key industry actors and by strengthening overall network connectivity through public support. Public policy should try to facilitate the development of more European organisations that can be characterised as global network hubs, on the one hand, and to draw larger numbers of the most dynamic small and medium-sized enterprises (SMEs) into these programmes, on the other, to avoid technological lock-ins and mitigate the resistance or network reorientation toward more productive research areas. 相似文献
