Visions to stay home by Visual services for home delivery

An appraisal of future, comprehensive visual telecommunication services is presented. Central to this appraisal is an identification of benefits the services may yield, and a separate examination of problems that might offset the benefits. While it appears that service providers and product suppliers will gain substantially from such services, benefits to users are not so evident.     

The Masakhane campaign: Alice and King William's Town case studies

The high‐profile media launch of the Masakhane campaign heightened awareness of issues associated with local government and service provision, However, delivery and improvement of services at local level have been slow or even non‐existent, resulting in a general feeling of despondency. Fortunately, this situation is being challenged as some towns implement their own campaigns with increasingly promising results, as this article will show by tracing developments in Alice and King William's Town. Their experiences, together with those of a number of other towns, point to some exciting possibilities in achieving the ideals of the Masakhane campaign at local level.     

On the optimal use of loose monitoring in agencies

We study the governance implications of firms being privately informed of their potential productivity before contracting with an agent to supply unobservable effort. We show that it can be optimal for high potential firms to have “loose monitoring” in the sense that the monitoring system is less perfect than what is implied by a standard agency model a la Holmstrom (The Bell J Econ 10:74–91, 1979). Loose monitoring is used to achieve separation among different types of firms such that firms with low potential do not have incentives to imitate contracts offered by high potential firms. Our findings imply that although loose monitoring may be a symptom of firms squandering scarce resources provided by investors, it can also arise as an optimal contracting arrangement.     

‘Better safe than sorry’: consumer perceptions of and deliberations on nanotechnologies

Although nanotechnologies are considered key technologies that can drive growth‐generating innovations in well‐saturated markets, worldwide investment in nanotechnologies has to date focused largely on technology‐related development programmes and little effort has been expended to research associated risks. As a result, even though prior discourses have sensitized western consumers to potential health‐related dangers, solid knowledge on, for example, the toxicological and eco‐toxicological risks and unintended side effects of nanotechnology are scarce. This paper therefore presents an overview of the current evidence on consumer knowledge and perceptions of nanotechnology and public engagement with it, with a focus on the US, the UK and Germany. Overall, even though survey data suggest that awareness of the term ‘nanotechnology’ has risen slightly, today's consumers are generally ill informed about its nature and its applications in consumer‐related products. Hence, based on our analysis of these data, we argue that early political engagement in the nanotechnology issue – for example, consumer policy options that support consumer interest in the marketing of ‘nanos’– would facilitate objective public discourse.     

New Keynesian monopolistic competition and objective demand

The New Keynesian model of monopolistic competition by Blanchard [Blanchard, O., Kiyotaki, N., 1987. Monopolistic competition and the effects of aggregate demand. American Economic Review 77 (4), 647–666] is reformulated according to an objective demand approach making the behavior of all agents fully rational. The revised model is compared with the original model in terms of prices, quantities and welfare. Working with the revised model enhances the validity of the menu-cost argument and, different from the original model, implies that price rigidity is increasing in market concentration.
