Acetylcholinesterase treatment,modelling potential demand and auditing practice

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 12 2001
Simon Lovestone
Abstract Background Acetylcholinesterase inhibitors represent an entirely novel treatment option for patients with Alzheimer's disease (AD). As such they represent a significant change in practice and a significant cost pressure on funding bodies. Objectives To assess the impact of cholinesterase inhibitors on routine clinical practice. Methods We estimated potential demand for the compounds taking into account eligibility criteria and prescribing practice agreed between clinicians and funders. We then audited actual prescribing practice assessing whether the estimated demand matched actual demand and whether practice and prescribing criteria were adhered to. Results Over a two-year period we estimated the demand for treatment at a total of 89 patient years for the population of the audit unit. In practice only 24.5 patient years of therapy were received, the short fall apparently being due to low referral rates for treatment. Prescribing by clinicians matched practice guidelines and a high proportion of three monthly assessments using scales for cognition, function and global state were performed. Using these assessment procedures treatment successes could be differentiated from primary and secondary treatment failures and, where apparently appropriate, treatment could be stopped. Conclusion In the real world of clinical practice demand for treatment in AD is modest but likely to grow and assessment with an aim to identifying those receiving benefit from treatment can be achieved.

Identifying Demand and Supply of Part-time Jobs Using Personnel Data.

LABOUR, Issue 4 2000
An Application to Italy
The percentage of part-time workers in Italy is very low compared with most European countries. In this paper we try to contribute to an explanation. We use data on the employees of a large Italian company operating in the service sector, and apply a particular econometric framework that allows identification of potential demand and supply. We find that demand and supply are potentially very large on average, but they are difficult to match at the individual worker/job level. The firm might observe a relevant employee's characteristics that are positively correlated with the employee's propensity to a part-time job but are negatively correlated with the profitability of that employee on that job. The firm might also use the revealed willingness to switch to a part-time job as a sign that the employee is likely to be unprofitable for the company. [source]

Demand for information and communication technology-based services and regional economic development,

PAPERS IN REGIONAL SCIENCE, Issue 1 2003
Eduardo Anselmo de Castro
Information and communication technology; demand modelling; network externalities; regional economic convergence Abstract. The relationship between the uptake of Information and Communication Technology-based services (ICT) and regional economic development is examined here; we address in particular the idea that ICT will promote regional economic convergence. We argue that ICT can generate contradictory trends of regional convergence and divergence and that, under conditions of non-regulated market supply, the effects leading to divergence can be dominant. The approach is based on the development of a regional demand model, which is the combination of two sub models, one dealing with the effects of network externalities and the other based on the concept of potential demand for ICT. The main conclusion is that less populous, more peripheral and poorer regions with weaker existing social and economic networking will encounter problems of insufficient demand. This in turn will delay the launch of new services and slow the rate of uptake. Negative dynamic effects of low ICT use on economic performance will generate a vicious circle of cumulative disadvantage. [source]

Auctions Versus Beauty Contests: The Allocation of UMTS Licences in Europe

ANNALS OF PUBLIC AND COOPERATIVE ECONOMICS, Issue 1 2003
L. Cartelier
The deployment of the so-called UMTS 3rd generation mobile networks is a step of vital importance for the promotion of competition in the telecommunications sector. The provision of high-traffic services presupposes that operators have access to the hertzian spectrum. The hertzian spectrum is a natural resource whose scarcity derives from the fact that only part of it is usable, for both technical and economic reasons. While the resource was sufficient to meet users' needs, the hertzian spectrum was allocated for little or no charge, on the principle of ,first come, first served'. However, with the explosion of technical progress in transmission technologies, new applications and new forms of use appeared, leading to a drastic increase in potential demand. It is in this context that the idea of charging for use of the spectrum arose, so as to discourage uneconomical use of the resource (e.g. stockpiling, wastage), to ensure a fair allocation between competing users and to forestall congestion. The purpose of this paper is first to examine the procedures for the allocation of hertzian spectrum operating licences, from the points of view of efficiency, transparency and sharing of the surplus. We shall then compare the results from the two approaches that were actually used in Europe: the open ascending auction and the beauty contest, before turning our attention to new forms of public action that result from the process of liberalization.

Producer Willingness to Pay for Precision Application Technology: Implications for Government and the Technology Industry

CANADIAN JOURNAL OF AGRICULTURAL ECONOMICS, Issue 1 2003
Darren Hudson
This paper focuses on the willingness to pay (WTP) for precision application/site-specific management technologies on the part of agricultural producers. We use a contingent valuation survey to elicit WTP for a package of technologies and examine the impact of government subsidies on potential demand. Results suggest that producer WTP is significantly lower than current technology prices, necessitating a 60% government subsidy to induce adoption, on average. Agronomic factors such as soil characteristic variability and soil quality are important determinants of WTP. In addition, how well the technology integrates into current farming practices and equipment also appears important. Les auteurs s'intéressent à la volonté des agriculteurs de payer pour des applications de précision ou des technologies de gestion adaptées à l'exploitation. Ils recourent à une étude d'évaluation des contingences pour jauger la volonté de payer un ensemble de technologies et pour préciser l'incidence des subventions gouvernementales sur la demande potentielle. Les résultats laissent croire que la volonté de payer est sensiblement plus faible que le coût actuel de la technologie, de sorte que l'adoption d'une technologie requiert une subvention publique de 60 %, en moyenne. Les paramètres agronomiques comme la variabilité des propriétés et la qualité du sol jouent un rôle important dans la volonté de payer. Enfin, la manière dont une technologie s'intègre aux pratiques agricoles et au matériel existants paraît aussi avoir son importance en la matière. [source]
