In the previous decades, a number of studies have been conducted to analyse the causal relationship between electricity consumption and economic growth in the Portuguese economy. However, the evidence remains controversial because the previous studies do not provide clear causality evidence. This might be attributed to the omitted variables bias because most previous studies only focus on the relationship between electricity consumption and economic growth in a bi-variate model. This paper attempts to re-investigate the relationship between electricity consumption and economic growth in Portugal using a multivariate model. Based on the bounds testing approach to cointegration and the Granger causality test within the vector error-correction model (VECM), our empirical results confirm the presence of cointegration among the variables. Moreover, there is evidence of bi-directional causality between electricity consumption and economic growth in the short- and long-run. This suggests that energy is an important source of economic growth in Portugal. Therefore, energy conservation policies should not be implemented because it would deteriorate the process of economic growth and development of the Portuguese economy. © 2013 Elsevier Ltd. Source

The aim of this study is to show how a Kohonen map can be used to increase the forecasting horizon of a financial failure model. Indeed, most prediction models fail to forecast accurately the occurrence of failure beyond 1 year, and their accuracy tends to fall as the prediction horizon recedes. So we propose a new way of using a Kohonen map to improve model reliability. Our results demonstrate that the generalization error achieved with a Kohonen map remains stable over the period studied, unlike that of other methods, such as discriminant analysis, logistic regression, neural networks and survival analysis, traditionally used for this kind of task. © 2011 Elsevier B.V.

Game companies use five components-four core components and one complementary one-in a 5Cs model to ensure the control and development of virtual worlds. A multidisciplinary review of the literature reveals that game companies make use of copyright, codes, creativity, and community to do this. They use the contract as a complementary component to reinforce their control over the four basic components and to compensate for the lacunae they present. In order to examine the extent to which game companies use the contract in this way, an analysis is performed of all contractual documents from a sample of 20 virtual worlds, providing evidence of general trends and emphasizing any differences between the virtual worlds in terms of the business and gaming models sought by each game company. An explanation is provided of why these contracts do not constitute a sustainable model for the game companies, given the high level of legal insecurity they present. Some basic recommendations can be made in order to improve the sustainability of the 5Cs model by modifying these contracts in such a way that they are enforceable and by matching their content with appropriate business and gaming models. This could lead to further studies aimed at providing answers to some of the intriguing issues affecting scholars and practitioners. Source

This article extends the understanding of oil-stock market relationships over the last turbulent decade. Unlike previous empirical investigations, which have largely focused on broad-based market indices (national and/or regional indices), we examine short-term linkages in the aggregate as well as sector by sector levels in Europe using different econometric techniques. Our main findings suggest that the reactions of stock returns to oil price changes differ greatly depending on the activity sector. In the out-of-sample analysis we show that introducing oil asset into a diversified portfolio of stocks allows to significantly improve its risk-return characteristics. © 2010 Elsevier Ltd. Source

This original study examines the potential of a spatiotemporal autoregressive Local (LSTAR) approach in modeling transaction prices for the housing market in inner Paris. We use a data set from the Paris Region notary office (Chambre des notaires d'Île-de-France) which consists of approximately 250,000 transactions units between the first quarter of 1990 and the end of 2005. We use the exact X-Y coordinates and transaction date to spatially and temporally sort each transaction. We first choose to use the STAR approach proposed by Pace et al., 1998. This method incorporates a spatiotemporal filtering process into the conventional hedonic function and attempts to correct for spatial and temporal correlative effects. We find significant estimates of spatial dependence effects. Moreover, using an original methodology, we find evidence of a strong presence of both spatial and temporal heterogeneity in the model. It suggests that spatial and temporal drifts in households socio-economic profiles and local housing market structure effects are certainly major determinants of the price level for the Paris Housing Market. © 2011, Wiley Periodicals, Inc.
