Identifying the scope effect on a meta-analysis of biodiversity valuation studies

Insensitivity to scope is an issue of much debate in contingent valuation (CV) even today. Although the literature about insensitivity to scope is abundant, the reasons for it are not yet well known. Through a meta-analysis of CV studies of biodiversity, the treatment of the different possible measures of the quantity of the good is explored in relation to scope sensitivity. Overall, the findings suggest that CV results are sensitive to the amount of the good being valued, although the result depends on how the environmental change is measured. Results support the use of absolute sizes when conducting CV studies.     

Employee reactions to voice and choice in the workplace: the influence of culture

The present study investigated the effect of culture on a much-prescribed management practice, that of employee participation in decision making. A survey was conducted among employees from two countries culturally distinct in the dimensions of power distance and individualism, namely Canada and the Philippines. Given eight decision-making scenarios that varied in terms of whether voice and/or choice was given to the employee and in terms of the importance of the outcomes, the respondents were asked about their perceptions of fairness of the procedures and outcomes, satisfaction with the procedures and outcomes, and preference for the decision-making procedures. Results show a highly significant country decision-making mode outcome importance interaction effect, but not in the directions expected. Overall, the Philippine sample registered more positive reactions to participation in decision making, although the Philippines' higher rank in power distance and lower rank in individualism than Canada seem to indicate otherwise. The results, together with a previous study conducted in high power distance-low individualism Mexico, forcefully suggest that employee participation in decision making may be successfully transferred.     

A signalling model of school grades under different evaluation systems

We examine the role of school grades as a signal of worker productivity under different examination systems in relation to errors that may affect student performance. Firms use school grades as a signal of workers’ effective skills, taking into account that these evaluations are effected by stochastic shocks. We show that more precise evaluation systems, being associated with a higher reactivity of wages to school grades, induce students to provide more effort. Low ability students tend to react less than high ability students. Moreover, individuals with low abilities may prefer less accurate evaluation systems. Nevertheless, when productivity increases, these systems become less convenient and the number of individuals preferring them diminishes. Our analysis highlights an important trade-off between centralised and decentralised evaluation systems. On the one hand, frequent evaluations, typical of decentralised systems, weaken the impact on grades of those errors which influence student performance and, so, reduce signal noise, while, on the other hand, different teachers generally adopt different performance assessment standards, leading to noisier evaluations.     

A macroeconomic analysis of the public investments in European combined transport

Intermodal transport has been recognized as a priority by the European Union, that has defined different budget allocations of investments to improve the shifting from road to intermodal transport, which is more sustainable. In this context, the main aim of the paper is to discuss the macroeconomic effects, in terms of economic growth, welfare and trade, of these public investments for combined transport, which aspects have been neglected in literature. A multi-country computable general equilibrium model has been used. The main results have been that the European Union benefits from these investments, but at international level, USA and Japan would lose in terms of welfare. Furthermore, the welfare change has been decomposed in its components and the results show that the trade effects are higher than the allocative effects. The robustness of the results has been tested over time and by a sensitivity analysis of the exchange rate.     

“It's not Easy Being Green”: Exploring Green Creeds,Green Deeds,and Internal Environmental Locus of Control

The authors report on the development of a novel construct, internal environmental locus of control (INELOC), which captures consumers’ multifaceted attitudes pertaining to personal responsibility towards and ability to affect environmental outcomes. Using data gathered from a sample of consumers, the linkages between INELOC and a wide array of environmental behaviors were investigated. Exploratory and confirmatory factor analyses revealed four first‐order dimensions (“green consumer,” “activism,” “advocate,” and “recycling attitudes”) embedded within a second‐order INELOC factor. Structural equations modeling techniques showed that INELOC was a strong positive predictor of many behaviors. However, the nature of the attitude–behavior relationship varied considerably across behavioral contexts, implying that people do not consistently behave in a proenvironmental manner. © 2012 Wiley Periodicals, Inc.     

EU Enlargement and the Portuguese Economy

The main focus of the present paper is on the emerging and likely future trade effects of enlargement. Though our particular concern is with Portugal, we set the scene by comparing the trade structures of the 10 countries of Central and Eastern Europe (i.e. the eight CEE accession states plus Bulgaria and Romania) – including an analysis of the individual cases of the Czech Republic, Hungary and Poland – with those of the EU15 as a whole, and with those of the 4 EU cohesion countries. The elimination of trade barriers between incumbents and accession states will have two trade‐related effects on EU incumbents: an increase in bilateral flows with the CEEC and a shift effect as the CEEC displace some incumbent exports to EU markets. The first effect is likely to be strongest for those incumbents for which there is a strong overlap between their export structure and the import structure of the CEEC. Portugal emerges as one of the economies with the least overlap. The displacement effect, we conclude, is likely to be particularly strong in the case of Portugal, given the high degree of similarity between Portuguese exports and those of the CEEC. Portugal appears to be ‘being squeezed from below’ in that, for the majority of its traditional export sectors, the CEEC became progressively more competitive during the second half of the 1990's. Portuguese specialisation was increasingly confined to low‐technology, low‐added‐value sectors with declining demand, as strong FDI inflows to the CEEC led to an increasing preponderance of more dynamic sectors in their export structures. Thus, Portugal is also being squeezed from above. This suggests that there may be substantial industrial disruption, in response to which labour‐market flexibility and dynamic entrepreneurial response is crucial. Intersectoral mobility is generally easier the more highly educated the workforce – an indicator on which Portugal scores poorly. The Portuguese labour market, however, displays a high degree of flexibility, consistent with its long lasting low rate of unemployment. Continued flexibility will help minimise these likely adjustment costs. Besides the trade and industry effects, other topics considered in the paper include the implications of enlargement for Portugal's ability to attract FDI, the likely consequences for Portugal of inward migration from the CEEC to the EU, and the implications of enlargement for Portugal's budgetary relations with the rest of the EU.     

The generalized bin packing problem

In the Generalized Bin Packing Problem (GBPP), given two sets of compulsory and non-compulsory items characterized by volume and profit and a set of bins with given volume and cost, we want to select the subset of profitable non-compulsory items to be loaded together with the compulsory ones into the appropriate bins in order to minimize the total net cost. Lower and upper bounds to the GBPP are given. The results of extensive computational experiments show that the proposed procedures are efficient and the bounds are tight.     

Project Management of Production Line Automation: A Comparative Analysis of Project Management in Brazil and Colombia

This article aims to evaluate the production line automation projects developed by Brazilian and Colombian companies from the Project Management perspective, through the analysis of the application degree of PMBOK processes, to understand how formal techniques are being employed in these countries and also to identify improvement opportunities, when necessary. Data were collected through a survey. The similarity index between the ten processes, with the highest application degree in the Brazilian and Colombian samples, was 70%. For the processes with the lowest application degree, the similarity index was 60%. No similar study was found in the literature.
