This research aims to analyse the drivers to company innovation and their effects on the financial performance. This study is based upon a sample of companies, located in two neighbouring countries (Portugal and Spain). Linear regression was the methodology deployed to analyse the importance of innovation types (differences between Portugal and Spain). To analyse the extent to which the innovation capacity variables influence financial performance (turnover), we made recourse to Probit Regression models. Our results show significant differences in terms of both the drivers and inhibitors to innovation in these two countries. The introduction of products into new markets only proved significant at Spanish companies whilst innovations in both products and processes are significant in both sets of Iberian companies.  相似文献

This paper analyses the production technology of Portuguese banks during the 1992–2006 period through the estimation of a translog cost frontier. This period is of major interest because it covers Portugal’s euro area accession and its impact on the banking system. Hence, critical factors impacting the banking system are identified against the background of increasing financial integration prior to the financial crisis that started in 2007 and later translated into strains in some European sovereign debt markets. Banks are modelled as firms which produce loans and other earning assets, choosing the cost minimizing combination of labour, capital and interest bearing debt, subject to holding a predetermined level of equity. According to the results of this study, technological progress has shifted the cost frontier downwards throughout the period under consideration, whereas the distance at which banks have operated from the frontier seems to have remained constant. Further, increases in production under scale economies have also contributed to the recorded increase in productivity.  相似文献

The provision of identities online continues to be a fiercely debated topic in policy circles, with proposals emerging for public sector organizations to leverage pre-existing social networking services for their own identity management purposes. Within the broader context of private sector organizations springing up as identity providers, this article explores — from a socio-legal perspective — the merits and drawbacks of using social networking services for government eID in Europe. It then reviews the present and future European policy environment concerning official use of social networking credentials. We focus specifically on legislative measures currently being proposed in the EU to facilitate the Identification, Authentication and Signature policy, within the scope of the ongoing Electronic Signatures Directive revision process and the launch of the proposed Electronic Trust Services Regulation.  相似文献

Increasingly, innovation is conceived in a context of conventions or rules and complexity. However, there is a need for a theoretical basis that describes the innovation process based on complexity. In this essay, we propose a multilevel micro-meso-macro framework that aims to meet this need and further the discussion on complexity. In this framework, the rule is adopted as an analytical concept and used to establish a bridge between the several theories employed. Two gaps are identified in the innovation process: the first is related to the simplicity with which complexity is generally treated, and the second refers to a lack of focus on the rules embedded in the theories used in innovation. The goal of this theoretical essay is to propose a multilevel micro-meso-macro framework, based on the rules and principles of complexity, which can be used to analyze the innovation process. As a result, we propose a new framework in which the innovation rules and the interactions between those rules are detailed and based on principles of complexity.  相似文献

This paper details the design and implementation of a participatory modelling process in the Baixo Guadiana River Basin, in Portugal. A group of stakeholders was involved in a causal mapping exercise that lead to the development of a shared view of the problems, pressures and impacts characterizing the river basin. A simulation model was also developed to support experimentation with alternative management scenarios for the area. The paper looks critically at the evaluation of the participatory modelling outcomes, both at the individual and group levels, discussing the role of this approach in supporting the scoping stages of river basin planning and management processes. On the downside, the unstable group composition seems to have hindered the chances of producing a higher impact in the functioning of the group, and subsequently the capacity to sustain the level of collaboration required to achieve the strategic river basin objectives established during the participatory modelling process. The paper discusses the issue of group stability as well as some options to overcome the limitations of unstable participant groups. The strengths of participatory modelling, as underlined by the Baixo Guadiana experience, include the flexibility to adapt the method to different contexts and participatory designs and the capacity to structure the active involvement of stakeholders, providing an open and shared language for collaborative policy design, fostering learning and knowledge integration.  相似文献

This paper presents a methodology for estimating the Brazilian GDP quarterly series in the period between 1960–1996. Firstly, an Engle–Granger’s static equation is estimated using GDP yearly data and GDP-related variables. The estimated coefficients from this regression are then used to obtain a first estimation of the quarterly GDP, with unavoidable measurement errors. The subsequent step is entirely based on benchmarking models estimated within a state space framework and consists in improving the preliminary GDP estimation in order to both eliminate as much as possible the measurement error and that the sum of the quarterly values matches the annual GDP.

Abstract: This paper explores the main determinants of the use of the cost accounting system (CAS) in Portuguese local government (PLG). Regression analysis is used to study the fit of a model of accounting changes in PLG, focused on cost accounting systems oriented to activities and outputs. Based on survey data gathered from PLG, we have found that the use of information in decision‐making and external reporting is still a mirage. We obtain evidence about the influence of the internal organizational context (especially the lack of support and difficulties in the CAS implementation) in the use for internal purposes, while the institutional environment (like external pressures to implement the CAS) appears to be more deterministic of the external use. Results strengthen the function of external reporting to legitimate the organization's activities to external stakeholders. On the other hand, some control variables (like political competition, usefulness and experience) also evidence some explanatory power in the model. Some mixed results were found that appeal to further research in the future. Our empirical results contribute to understand the importance of interconnecting the contingency and institutional approaches to gain a clear picture of cost accounting changes in the public sector.  相似文献

In the paper we investigate the empirical features of euro area money market turbulence during the recent financial crisis. By means of a novel Fractionally Integrated Heteroskedastic Factor Vector Autoregressive model, we find evidence of a deterministic level factor in the EURIBOR-OIS (OIS) spreads term structure, associated with the two waves of stress in the interbank market, following the BNP Paribas (9 August 2007) and Lehman Brothers (16 September 2008) “shocks”, and two additional factors, of the long memory type, bearing the interpretation of curvature and slope factors, respectively. The unfolding of the crisis yields a significant increase in their persistence and volatility. We also find evidence of a declining trend in the level and volatility of OIS spreads since December 2008, associated with ECB liquidity policies.  相似文献

The objective of this study is to identify the weighted importance of intrinsic and extrinsic attributes. Intrinsic attributes are defined as the specific features of products. Extrinsic attributes refer to other characteristics that are also important for price composition, such as brand, store layout and services, and purchasing experiences. In a survey with 1,923 collected responses, it was possible to identify and quantify intrinsic and extrinsic influencing factors beyond price strategy in the Brazilian fashion market for blue jeans. The statistical analysis was based on the hedonic price method. The idea of expressing the price based on a series of intrinsic and extrinsic variables avoids the problem of using the regression technique. In this research, multiple linear regression and quantile regression were applied. The results show that extrinsic attributes have greater influence than intrinsic features on explaining the final market prices using log-linear and quantile regression statistical methods.  相似文献
