Some comparative-statics results for nonlinear input-output models of a multisectored economy,and related results for nonlinear price-demand relations

For a nonlinear version of the linear input-output model of Leontief, we consider the effect, on the vector x of total gross outputs, of changes in the components of the final-demand vector c. For example, it is shown that, for a certain important class of models, the “large-change elasticity” of any component of x, with respect to any component of c, is less than or equal to unity. Some similar results are proved concerning properties of nonlinear price-demand relations for the case in which all goods are weak gross substitutes. Unlike earlier work in this general area, we do not introduce hypotheses concerning the indecomposability or homogeneity of certain mappings. For that reason, the results are valid for the price-demand relation for a single firm, or for any collection of firms.     

Above and beyond? How businesses can drive sustainable development by promoting lasting pro-environmental behaviour change: An examination of the IKEA Live Lagom project

Current global changes require new business approaches driving sustainable development on all fronts. To date, most business approaches have focused on sustainable marketing and corporate social responsibility initiatives. In this field study, we examine IKEA's Live Lagom project, a 3-year behaviour change initiative that aimed to explore how to go above and beyond conventional approaches demonstrating how businesses could support sustainable development by supporting their customers' attempts to live more sustainable lifestyles. We examined the effectiveness of the project involving multifaceted behaviour change interventions, testing for behavioural changes both during and after the project period. In addition, we explored changes in participants' attitudes towards the company. Findings show that the extensive set of interventions led to changes in pro-environmental behaviours across all three participant groups with potentially positive impacts on the customer–company relationship. The article thus provides a call for further businesses to engage in similar behaviour change projects that would allow citizens to engage in more sustainable lifestyles and behaviours across contexts.     

‘Devolution’ of transport powers to Local Government: Impacts of the 2004 Traffic Management Act in England

The concept of ‘Devolution’—the transfer of powers away from the Central Government to more local bodies of Government, has been used across many different areas of policy and by many different national governments. This paper examines the devolution of transport powers to the existing Local Traffic Authorities in England via the 2004 Traffic Management Act. The paper first presents a summary of how several different nations have undertaken this process of devolving transport powers and responsibilities to either new or existing bodies. It then presents research from an electronic survey concerning how English Local Traffic Aut`horities are choosing to use some of the new powers available to them and their opinion on complementary areas of transport policy. Research is also presented from structured telephone interviews, concerning how individual Local Authorities perceive the efficacy and equity of the new legislation. Overall, the results show that only some of these new powers are likely to be used by English Local Authorities, with limited variation in how different types of LTA are choosing to implement these new powers. The structured telephone interviews provided some evidence that rural Authorities in particular are more dissatisfied with the legislation and consider some of the measures unhelpful. The results provide some insights on the formulation of devolved policy applicable to existing Local Government bodies and the varying benefits that can be perceived to apply to different types of Local Authority. Conclusions are drawn on some of the practical difficulties arising from the English experience, and lessons of relevance are drawn for other nations considering a similar devolution of transport powers.     

The utilization of individual capabilities in group approaches to strategic decision-making

Previous research has found that groups using dialectical inquiry (DI) or devil's advocacy (DA) make better strategic decisions than groups using a consensus (C) approach. This paper explains those findings by using new data to show that the DI and DA approaches make better use of the capabilities of individual group members. Specifically, the DI and DA groups yielded significantly higher quality recommendations and assumptions than the average of the individuals in the respective groups, whereas the C groups did not. Moreover, the recommendations and assumptions of the DI groups and the recommendations of the DA groups significantly exceeded those of the best individual in the respective groups. There were no significant differences for the C groups.     

Planning and control from the perspective of labour: A short presentation of the demos project

The objective of the DEMOS project (Democratic Planning and Control in Working Life) is the development of knowledge about planning, control and computer use. It is based upon the interests of workers and their trade unions and consists of two parts. The first is the study and analysis of corporate planning, control and computer use in cooperation with investigative groups in selected local unions, simultaneously testing trade union procedures in investigations. The second part relates to the development of alternative theories and research methods which differ from the current, dominating perspective. The project is expected to be of significance to continued interdisciplinary research on working life with a trade union connection. The results can be of use in trade union negotiations and judgements, both centrally and locally, and constitute a basis for educational materials both for unions and for state schools.
