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.     

Architectural innovation in product development through early supplier integration

The paper explains how an important opportunity exists to pro-actively integrate suppliers at an early stage in the concept exploration and definition stages of product development. Research suggests that the concept of architectural innovation can be extended so that product features are matched with the associated specialized technical skills of partners in the development team.
In addition to the establishment of integrated product teams, key enablers include: long-term commitment to suppliers; co-location; joint responsibility for design and configuration control; seamless information flow; and retaining flexibility in the definition of system configuration. Important contributing factors include: supplier-capability-enhancing investments; target costing; and incentive mechanisms. To promote innovative outcomes in military and government programmes, attention is drawn to the importance of governments championing closely-knit customer-supplier relationships.
Firms can build enduring competitive strength by leveraging the specialized knowledge bases of their supplier networks. Two case-studies provide lessons to improve current approaches to the creation of long-term partnerships, or strategic alliances, with suppliers.     

The adaptation of hospitality and retail firms to the NMW: a focus on the impact of age‐related clauses

A lower national minimum wage for 18‐ to 21‐year‐olds and the exclusion of all workers under 18 prompted fears of a distortion in the British labour market and an undermining of training initiatives. Empirical data collected from employers in two low paying sectors, revealing the full utilisation of young workers and under‐utilisation of training initiatives, ensure these fears are not justified and that the government's basis for the lower rate cannot be substantiated.     

Optimal growth with many consumers

A method is described for constructing all Pareto-optimal allocations for a dynamic economy with many heterogeneous consumers, under certainty, in which both the technology and consumer preferences are recursive but preferences need not be additively separable over time. Optimal (perfect foresight competitive equilibrium) allocations are obtained through the study of a dynamic program. For an economy with one consumption good, sufficient conditions are given for the existence of a unique interior stationary distribution of consumption and wealth. For a two-person exchange economy, sufficient conditions are given for the global asymptotic stability of the unique interior stationary point.     

Optimal fiscal and monetary policy in an economy without capital

This paper is concerned with the structure and time-consistency of optimal fiscal and monetary policy in an economy without capital. In a dynamic context, optimal taxation means distributing tax distortions over time in a welfare-maximizing way. For a barter economy, our main finding is that with debt commitments of sufficiently rich maturity structure, an optimal policy, if one exists, is time-consistent. In a monetary economy, the idea of optimal taxation must be broadened to include an ‘inflation tax’, and we find that time-consistency does not carry over. An optimal ‘inflation tax’ requires commitment by ‘rules’ in a sense that has no counterpart in the dynamic theory of ordinary excise taxes. The reason time-consistency fails in a monetary economy is that nominal assets should, from a welfare-maximizing point of view, always be taxed away via an immediate inflation in a kind of ‘capital levy’. This emerges as a new possibility when money is introduced into an economy without capital.
