Ex Ante Hedging Effectiveness of UK Stock Index Futures Contracts: Evidence for the FTSE 100 and FTSE Mid 250 Contracts

Ex ante hedging effectiveness of the FTSE 100 and FTSE Mid 250 index futures contracts is examined for a range of portfolios, consisting of stock market indexes and professionally managed portfolios (investment trust companies). Previous studies which focused on ex post hedging performance using spot portfolios that mirror market indexes are shown to overstate the risk reduction potential of index futures. Although ex ante hedge ratios are found to be characterised by intertemporal instability, ex ante hedging performance of direct hedges and cross hedges approaches that of the ex post benchmark when hedge ratios are estimated using a sufficient window size.     

Group Work and Multicultural Management Education

Globalization changes the composition of the adult classroom, increasing diversity and bringing new associated teaching and learning problems; problems with group work. Educators may have goals to teach transferable multicultural group working skills yet learners find such work more challenging, showing a propensity to form groups containing students more like themselves i.e. unicultural. Using survey data from MBA students spanning 25 countries, this empirical article documents an investigation into methods and techniques used to create groups for teaching and learning in diverse classrooms and considers the arguments for and against a range of approaches. We conclude the educational goal directing the use of group work, student stage and the need for attaining affective and performance outcomes are important determinants of group allocation methods.     

Grocers' window displays: The eclipse of a British tradition

By reference to period retailing narratives, this paper examines the changed significance of shop window displays for British grocers with the transition from counter‐based to self‐service from the late 1940s to the 1960s. The ‘well‐dressed’ window showing a selection of goods and price offers became an early casualty of changed retail practices. Opportunities presented by self‐service for comprehensive stock displays and in‐store promotion proved a decisive challenge to the art of the grocer's window display. These displays had been ubiquitous; large and small shops alike tried to impress passers‐by with examples of their stock range. Self‐service shops had different internal space requirements and soon it was more important that potential customers could see the well‐stocked aisles and activity within.     

The Strategic Implications of EMU for European Banking

This paper reviews the broad impact of the European SMP (Single Market Programme) and approach of EMU (European Monetary Union) on European bank strategies.

Select but key aspects of the competitive strategies that banks might pursue in this ‘New Europe’ are then considered. Within this review; the key strategic question is explored whether banks necessarily have to be bigger in order to be more efficient and even ultimately to survive in a post-EMU world. It is argued thut efficiency considerations should dominnte over size per se. The strategic perspective that will be developed is to

view EMU as the next stage on from the present SMF! This perspective avoids the mistake of visuulising any kind of EMU as likely to precipitate dramatic ‘breaks’ in the present

strategic development of European banking. Since the SMP is well advanced, we already have some experience of the

strategic reactions of banks towards a single European banking market; this provides a useful indicator of at least some of the broader bank strategic reactions that might be expected to EMU.     

A robust house price index using sparse and frugal data

In this article, we describe a house price index algorithm which requires only sparse and frugal data, namely house location, date of sale and sale price, as input data. We aim to show that our algorithm is as effective for predicting price changes as more complex models which require detailed or extensive data. Although various methods are employed for determining house price indexes, such as hedonic regression, mix-adjusted median or repeat sales, there is no consensus on how to determine the robustness of an index, and hence no agreement on which method is the best to use. We formalise an objective criterion for what a house price index should achieve, namely consistency between time periods. Using this criterion, we investigate whether it is possible to achieve strong robustness using frugal data covering only 66 months of transactions on the Irish property market. We develop a simple multi-stage algorithm and show that it is more robust than the complex hedonic regression model currently employed by the Irish Central Statistics Office.     

The Allocation of Nutrient Load Reduction across a Watershed: Assessing Delivery Coefficients as an Implementation Tool

Delivery coefficients have long been used in economic analysis of policies that seek to address environmental problems like water pollution. However, the derivation and validity of delivery coefficients have not been examined carefully by empirical analyses. We derived estimates of delivery coefficients and then evaluated them as a bridge between complex simulation models and economic policies like water quality trading. We found that the allocations achieved outcomes that differed from intended water quality targets by less than 10% in most cases. For the least-cost allocation with heterogeneous costs, cost savings significantly outweighed deviations from water quality targets.     

A Genetic Algorithm Approach to Farm Investment

A farm portfolio model is specified with two risky enterprises and a risk-free asset which may be held short or long by the farmer. The model is solved numerically using a genetic algorithm. It is shown that the assumption of competitive adaptation leads to a violation of normative efficiency. Those who survive are not the most efficient in a normative sense.     

Experience,change and vulnerability: consumer education for older people revisited

Everyday consumer transactions have the same potential for unexpected consequence whatever the age of the consumers involved. Young and old alike can find that products and services fail to live up to performance claims and that they are left with problems not easily resolved, or costs that are difficult to recover. While not overlooking consumer heterogeneity – especially on the basis of age – older consumers are arguably distinguishable in terms of the social and financial context in which they make decisions and attempt to redress problems. In 1988, attention was drawn to the need for consumer education to look beyond generic objectives to the specific situation of older people and their transactions. More than a decade later, in an allegedly consumer‐oriented society, the issue is revisited here to assess the argument's current relevance. Despite the increased availability of information for decisions and consumer protection, difficulties persist in the way information is presented or accessed. Chameleon‐like, old problems become manifest in new unfamiliar ways and invalidate experience. Consumer education today is as important as it was in 1988. Arguably, technological change means that the need for a better understanding of dangers, rights and redress procedures is greater than ever and the needs of older people in increasingly complex private and public sector transaction environments are all the more pressing. However, a fundamental revision of the way we approach the design of products, services and environments is needed to improve prospects for older consumers.
