Economic impact assessment of mega infrastructure pipeline projects

The economic development features for the decades after the Second World War provide evidence that investments to new infrastructures are a key driver in strengthening the national economy and enhancing nation’s productivity, as it creates economic benefits and additional income. However, the decision for fund allocation and investments in mega infrastructure pipeline projects often must be made in conditions that are much more fraught with uncertainty. The key question in such decisions is if the economic impact caused by the new project could be able to essentially boost the economy by creating new jobs and generating new income on one hand; and which are the business sectors expected to archive the benefits of this investment. This article deals with the estimation of the mega infrastructure pipeline project economic effects in economy. The methodological framework is based on input–output approach providing quantitative estimations about the economic impact of the project in terms of new income and jobs. The numerical application deals with the assessment of a cross-border crude oil pipeline project, connecting the ports of Burgas (Bulgaria) and Alexandroupolis (Greece), establishing a new transportation corridor for the crude oil from Black Sea to Southeast Mediterranean.     

Bank/sovereign risk spillovers in the European debt crisis

This paper investigates contagion between bank and sovereign default risk in Europe over the period 2007–2012. We define contagion as excess correlation, i.e. correlation between banks and sovereigns over and above what is explained by common factors, using CDS spreads at the bank and at the sovereign level. Moreover, we investigate the determinants of contagion by analyzing bank-specific as well as country-specific variables and their interaction. Using the EBA’s disclosure of sovereign exposures of banks, we provide empirical evidence that three contagion channels are at work: a guarantee channel, an asset holdings channel and a collateral channel. We find that banks with a weak capital buffer, a weak funding structure and less traditional banking activities are particularly vulnerable to risk spillovers. At the country level, the debt ratio is the most important driver of contagion. Furthermore, the impact of government interventions on contagion depends on the type of intervention, with outright capital injections being the most effective measure in reducing spillover intensity.     

Peer choice in CEO compensation

Current research shows that firms are more likely to benchmark against peers that pay their Chief Executive Officers (CEOs) higher compensation, reflecting self serving behavior. We propose an alternative explanation: the choice of highly paid peers represents a reward for unobserved CEO talent. We test this hypothesis by decomposing the effect of peer selection into talent and self serving components. Consistent with our prediction, we find that the association between a firm's selection of highly paid peers and CEO pay mostly represents compensation for CEO talent.     

Extending the Lee–Carter model: a three-way decomposition

In this paper, we focus on a Multi-dimensional Data Analysis approach to the Lee–Carter (LC) model of mortality trends. In particular, we extend the bilinear LC model and specify a new model based on a three-way structure, which incorporates a further component in the decomposition of the log-mortality rates. A multi-way component analysis is performed using the Tucker3 model. The suggested methodology allows us to obtain combined estimates for the three modes: (1) time, (2) age groups and (3) different populations. From the results obtained by the Tucker3 decomposition, we can jointly compare, in both a numerical and graphical way, the relationships among all three modes and obtain a time-series component as a leading indicator of the mortality trend for a group of populations. Further, we carry out a correlation analysis of the estimated trends in order to assess the reliability of the results of the three-way decomposition. The model's goodness of fit is assessed using an analysis of the residuals. Finally, we discuss how the synthesised mortality index can be used to build concise projected life tables for a group of populations. An application which compares 10 European countries is used to illustrate the approach and provide a deeper insight into the model and its implementation.     

Firm efficiency and stock returns

In this paper, we investigate the role of firm efficiency in asset pricing using a sample of US publicly listed companies for the period 1988–2007. We employ non-parametric data envelopment analysis (DEA) on various input/output combinations, focusing on sales and market value as output measures in the construction of the frontier technologies. Using these performance measures, we examine whether efficient firms perform differently from inefficient firms following standard financial analysis procedures. First, we employ performance attribution regressions, by forming portfolios based on efficiency scores and tracking the performance of the various portfolios over time. Second, we perform cross-sectional/panel regressions to determine whether firm efficiency indeed has explanatory power for the cross-section of stock returns. Our results suggest that firm efficiency plays an important role in asset pricing and that efficient firms significantly outperform inefficient firms even after controlling for known risk factors.     

Reducing burnout in call centers through HR practices

Previous research on call centers has demonstrated that human resource (HR) practices can be related to employee stress; however, these studies did not examine the linking mechanisms underlying these associations. Using the job demands–control (JD‐C) model as a theoretical framework, we examine perceived job demands (namely, emotional dissonance and quantitative demands) and autonomy as potential mediators in the relationship between HR systems and burnout (exhaustion and cynicism). We distinguish between HR control systems, which include performance monitoring practices, and HR involvement systems, which include training, participation, and performance‐related pay. This study samples 811 employees working in 11 call centers. Our findings support the idea that HR systems can help reduce burnout in call centers by verifying that HR control systems associated with more emotional dissonance and less autonomy increase burnout. On the other hand, an HR involvement system decreases workers' burnout because it alleviates the job demands of emotional dissonance and quantitative demands. This study fills a gap in the literature between HR systems and burnout by demonstrating the role job demands and autonomy play in explaining how HR systems improve or decrease workers' exhaustion and cynicism. © 2010 Wiley Periodicals, Inc.     

Prior knowledge and social networks in the exploitation of entrepreneurial opportunities

In this study we analyze the effects of prior knowledge and social networks on the exploitation of entrepreneurial opportunities. The prior knowledge considered is associated with the successes and failures experienced in the entrepreneurial trajectory and, therefore, derived from the exploitation of prior opportunities. In analyzing social networks, we examine the strength of the relationships between entrepreneurs, managers and entrepreneurial associations. As an explanatory factor of the entrepreneurial process, we also include the influence of the entrepreneurial opportunities recognized. Through a hierarchical regression analysis, we show that the number of potential opportunities recognized, the number of previous opportunities successfully exploited and the strength of entrepreneurial social networks positively influence the number of opportunities developed and exploited.     

Stress and coping in nurse managers: two decades of research

An integrative literature review was undertaken to examine the research related to stress and coping in nurse managers. Key gaps in the literature were identified with implications for research presented.
