Researches on Economic Evaluation Models of Investment Items above Sustainable Purport

This paper points out that traditional economic evaluation of investment items, without considering comprehensively the long-term environmental influences, emphasizes only on economic benefits, which makes it incompetent to meet the demand of sustainable development. It also discusses the economic evaluation models for investment items in accordance with the theories of sustainable development.     

Evaluating environmental and social performance of large Portuguese companies: a balanced scorecard approach

A thematic balanced scorecard format was used to address environmental and social performance evaluation of 13 large companies operating in Portugal. Financial aspects of environmental and social company activities are also included. Companies were categorized as to their actual performance status using a predefined performance framework. Three categories were found: compliance with the law while emphasizing pollution control, pollution prevention and eco‐efficiency. Management tools and procedural matters were found to be most relevant for categorization. Often, reported information did not allow for quantitative evaluation of environmental burden reduction. Use of the thematic balanced scorecard format was useful to better understand the strengths and weaknesses of links between objectives and measurements, initiatives and achievements. Improvement as to environmental performance was found to be paralleled by increased social performance, suggesting that a multi‐level ‘sustainability’ performance categorization of these Portuguese companies is feasible. Driving forces for environmental management initiatives were found to differ by category of performance. Copyright © 2005 John Wiley & Sons, Ltd and ERP Environment.

Determinants of consumers’ aesthetic responses to Point‐of‐Purchase materials

The four‐dimensional nature of the Kaplans’ model of aesthetic response to images was tested on Point‐of‐Purchase (POP) material. It was found that only two robust dimensions emerged in the analysis, Clarity and Mystery. These however, had a significant influence on the subjects’ rating of the POP’s attractiveness. Path analysis suggested each of these dimensions was independent of the other. The implications of the findings are discussed and possible future areas of research identified.

The impact of the Uruguay Round on tariff escalation in agricultural products

Tariff escalation (i.e. higher tariffs on processed agricultural products than on their input commodities) has been one of the obstacles for developing countries in their efforts to establish processing industries for exports. This article assesses the changes in tariff escalation resulting from the Uruguay Round (UR) tariff concessions, examining the agricultural import markets of EU, Japan and the US. The approach consisted of comparing the base and bound tariffs, as listed in the UR tariff schedules, of actual input/output processing relationships, taking also specific tariffs into account. Three main conclusions can be drawn. First, more than half of the commodity pairs have positive tariff wedges (escalating tariffs), about 10 per cent have no tariff wedges (input and output tariffs are equal) and the remaining one-third of the commodity pairs have negative tariff wedges (de-escalating tariffs). These numbers are roughly the same for both base and bound tariff wedges. Second, as a result of the UR tariff concessions more than 80 per cent of the tariff wedges have decreased (in absolute values, i.e. positive wedges have become less positive and negative wedges have become less negative). Convergence towards zero is therefore a common feature. Third, after the full implementation of the UR tariff concessions, high levels of nominal tariff escalation will still remain for a number of commodity pairs, highest in Japan and lowest in US. Considering only the positive tariff wedges, these will average 17 per cent after the implementation of the UR (down from 23 per cent of the base years). Finally, the study has certain methodological shortcomings, and a degree of caution is in order for countries contemplating export diversification and investing in valued-added industries. There are well known problems with “water in the tariffs” and the difference between applied and bound rates of duty that are common to all studies on this subject. In addition, a number of factors that are beyond the scope of this study should also be taken into account when export diversification is considered. These relate, inter alia, to the competitiveness of the export commodities or industries in question, availability of appropriate technologies and infrastructure, product standards, technical regulations and a host of consumer preference issues having to do with brand recognition as well as product characteristics.
