Public administrations have been adopting information and communication technologies (ICT) to transform their internal organization and provide better public services to citizens and firms. However, the external benefits, despite being deemed relevant, have been empirically overlooked. We first explore the relation between ICT diffusion in public administrations and business demography at the municipal level by studying the Italian context. Our results show that ICT diffusion in the PA contributes to significantly reducing the death rate of firms and boosting their turnover rate. The adoption of ICT in the PA also exerts a positive impact on the firm birth rate, although it is not statistically significant. These results shed light on the importance of promoting e-government and framing coherent digital agendas as public instruments for supporting entrepreneurship and regional economic development.  相似文献

One of the key features of our economies consists of the coexistence of different technologies supplying similar products and services. We often observe that an old technology is improved when a new one appears; behind this process of improvement often lies an intentional research activity. There thus begins a competition between the two technologies whose performances are improved via R&D. We focus our attention on this competition process and supply a formal model, based on the optimization of R&D expenditure of both technologies, which can describe the dynamics of the delayed overtaking of the new technology over the old one.  相似文献

The aim of this study is to analyze similarities and differences between companies with traditional sustainability reporting (TSR) and those that publish integrated reports. Based on institutional theory we identify potential determinants of integrated reporting (IR) and test their relevance empirically in a sample of 309 companies. Our analysis shows that IR companies are different from TSR companies with regard to several country‐level determinants. In particular, investor and employment protection laws, the intensity of market coordination and ownership concentration, the level of economic, environmental and social development, the degree of national corporate responsibility and the value system of the country of origin proved to be relevant. Based on these results, both implications for practice and future studies are derived. Copyright © 2011 John Wiley & Sons, Ltd and ERP Environment.  相似文献

This paper discusses, estimates and formally compares the best known procedures for incorporating demographic variables into complete demand systems. In particular, a class of general procedures belonging to Gorman's family of ‘general linear household technologies’ is introduced. Estimation and comparison of different procedures make use of Italian household budget data for the years 1973–1992, incorporating a single demographic variable (family size) into a Generalized Quadratic Almost Ideal Demand System. In our empirical example, however, even the most general household technologies are unable to fully capture the behavioural heterogeneity shown by the data.

The transition to digital television transmission (DTT) creates an opportunity for revising the current allocation and use of the spectrum, and for enhancing its efficiency. The fairly large amount of spectrum that will be freed up in the analog TV switch-off is known as the digital dividend. Many EU countries have decided to partially allocate these frequencies, through market mechanisms, to mobile use, but a large fraction of the dividend is supposed to remain in the hands of broadcasters. An efficient management of the spectrum requires that the use of this resource should be supported through appropriate incentive policies. This paper presents a techno-analytical approach to evaluate the opportunity cost of using a spectrum portion within the digital dividends’ bandwidths, for example around 800-900 MHz, for both DVB-T and UMTS services, specifically addressing the extraordinary rise in the use of mobile broadband in the European context. The methodology is then applied to Italy to derive a baseline for administered prices reflecting the cost of spectrum use. Results obtained are then compared with existing evidences from other studies and Countries’ experiences.  相似文献

This article reports on the economic implications to the USA and Western European economies after imposing protectionist trade policies on selected groups of imports till 2000. The effects of this policy are also presented for Japan and the non-oil-producing developing countries. Before discussing the results of the computations and the import restricting assumptions, a summary of the methodological framework, the World Input-Output Model, used in the computation is presented.  相似文献

The UK gas industry has undergone major changes since it was privatised in 1986 as a fully integrated monopoly. The most significant of these has occurred not as a result of the privatisation legislation but by the intervention of the ordinary competition authorities in support of an active industry regulator. While price capping continues to be used as the primary instrument for welfare protection against the still substantial monopolistic powers of the incumbent, new competition (which has been positively encouraged) has had the greater impact on prices and choice. Recently, however, the regulator has encouraged the use of auctions for the sale of storage capacity. This paper considers the merits of auctions and makes a tentative evaluation of their effectiveness. Further use of auctions is recommended but reserve prices are considered inappropriate where monopoly power still remains.  相似文献

On optimal unemployment compensation   总被引:1,自引:0,他引:1  
The design of an optimal unemployment compensation scheme is analyzed, using a dynamic principal-agent relationship between a risk-neutral planner (the principal) and risk-averse workers (the agents), where the planner's inability to observe workers’ job-search efforts creates a moral hazard problem. To design an implementable scheme, we require that each agent is guaranteed a minimum level of expected discounted utility, regardless of his past history. In contrast with previous studies, we find that the optimal contract is quite close to actual unemployment compensation schemes, both qualitatively and quantitatively.  相似文献
