OPTIMALITY OF RECYCLING AND THE LOCATION OF A RECYCLING CENTER

ABSTRACT. Consider a community investigating the integration of recycling into its waste management program. Even if (1) the county's citizens do not gain utility from recycling, (2) landfill space is plentiful, and (3) the market price for recyclables is zero, recycling can still be optimal for a local government. By determining the relationship between the amount of recycling and the location of a recycling center, conditions are identified under which recycling will reduce total waste management costs enough that municipal recycling will be optimal. In addition, it is shown that the likelihood of municipal recycling increases with the size of the city.     

Conflict, Uncertainty, and the Role of Planning and Analysis in Public Policy Innovation

Innovation by "groping along," in which appointed public officials experiment during program implementation after little, if any, initial planning and analysis, has been promoted as a more accurate model of policy innovation than the rational comprehensive model of policy change. Analysis of two cases of environmental regulatory policy innovation suggests that administrative agencies may be more likely to follow the conventional model of the policy cycle when high levels of conflict are likely to accompany policy initiatives. The cases also suggest, however, that public officials will experiment during the innovation process when they are uncertain about the nature of the problem and the probable impacts of alternative solutions.     

THE POSSIBLE FRACTIONATION OF LEAD ISOTOPES IN ANCIENT METALLURGICAL PROCESSES

The possibility of lead isotope fractionation in ancient lead production is examined. Kinetic theory relating to isotopic fractionation in non-equilibrium evaporation is considered and the feasibility of the alteration of lead isotope abundance ratios in ore roasting and smelting is assessed. Previous experimental work is shown to have been inconclusive and conclusions are drawn on the need for further research to quantify the possible extent of fractionation in practice.     

Technology networking in border regions: Case study of the Euregion Maas‐Rhine

This paper describes the results of a study investigating cross‐border networking by enterprises in the border region where the Netherlands, Belgium and Germany meet, the so‐called Euregion Maas‐Rhine. The study was undertaken in view of the completion of the Single European Market in 1993, which was expected to induce enterprises to make more effective use of available opportunities to improve their innovative and hence competitive potential. Special attention was given to knowledge transfer and sourcing of technology across borders. It was found that the majority of enterprises are still oriented towards a purely national environment. Technology‐intensive enterprises that are engaged in cross‐border networking, however, seem to be doing better than the ones that maintain a national orientation.
