Forecasting UK house prices: A time varying coefficient approach

Previous studies of UK house prices, developed from the demand and supply ofhousing or from the asset market approach have been poor in terms of robustness and ex-post forecasting ability. The UK housing market has suffered a number of structural changes, particularly since the early 1980s with substantial house price increases, financial market deregulation and the removal of mortgage market constraints through competition. Consequently, models which assume that the underlying data-generating process is stable and apply constant parameter techniques tend to suffer in terms of parameter instability. This article uses the Time Varying Coefficient (TVC) methodology where the underlying data-generating process in the UK housing market is treated as unstable. The estimation results of the TVC regression of UK house prices is compared with those obtained from three alternative constant parameter regressions. Comparisons of forecasting performance suggest the TVC regression out-performs forecasts from an Error Correction Mechanism (ECM), Vector Autoregressive (VAR) and an Autoregressive Time Series regression.     

Productivity and Producer Welfare in the Presence of Production Risk

Production risk is an inherent characteristic of agriculture and changes in production risk will affect the welfare of risk‐averse producers. Using standard concepts from the literature on uncertainty, we introduce a welfare measure which comprises total factor productivity (TFP), production risk and farmer risk preferences, and which reflects the impact on producer welfare of changes in production technology. An empirical application is carried out using data from a sample of Spanish dairy farms which shows how the positive impact of increases in TFP on welfare can be offset by increases in the risk premium (‘cost of risk’) to the point where welfare may decrease.     

A conceptual framework of anonymity in Group Support Systems

As the development and use of automated systems for collaborative work grows, the need for a better understanding of these systems becomes more important. Our focus is on one type of system, a Group Support System (GSS) and, in particular, on one important aspect of a GSS—anonymity. A conceptual framework for the study of anonymity in a GSS is presented, which describes the general classes of variables and their relationships. These variables include the factors that influence anonymity in a GSS, types of anonymity, and the effects of anonymity on a message sender, receiver, group process, and outcome. Each of these variables is discussed with working propositions presented for important group process and outcome measures. The objectives of this article are to highlight the importance and complexity of anonymity, to act as a guide for empirical investigations of anonymity, and to influence future GSS development and use.     

Pressure group power in the European Community

The renewed attention to the strengthening of the internal market of the European Community heralded by the Single European Act of 1986 is likely to produce a quantum leap in pressure group activity in Brussels, as business interests line up to exert their influence on the many harmonisation measures that are in the pipeline. How great an influence have European pressure groups exerted up till now? In what spheres has this influence been felt most strongly?     

Ethical decision making in the medical profession: An application of the theory of planned behavior

The present study applied Ajzen's (1985) theory of planned behavior to the explanation of ethical decision making. Nurses in three hospitals were provided with scenarios that depicted inadequate patient care and asked if they would report health professionals responsible for the situation. Study results suggest that the theory of planned behavior can explain a significant amount of variation in the intent to report a colleague. Attitude toward performing the behavior explained a large portion of the variance; subjective norms explained a moderate amount of the variance; and, perceived behavioral control added little to the explanation of variance. Implications for research and practice are discussed. Donna M. Randall is an Associate Professor in Management and Systems at Washington State University. Her research interests include organizational commitment, media coverage of elite crime, and ethical issues in management. Her publications have appeared in such journals as Decision Sciences, Academy of Management Review, and Journal of Business Ethics. Annetta M. Gibson is a doctoral student in the Department of Accounting and Business Law at Washington State University and a CPA. Her research interests lie in the area of behavioral accounting and ethical issues in auditing, accounting, and management. She has published in the Journal of Business Ethics.     

Generational incidence of savings taxation versus capital-income taxation

This paper examines the incidence of capital taxation in a model in which the taxation of capital is clearly justifiable and using analytical techniques from the tax reform literature. The taxation of capital has long been a controversial issue, with much of the literature concluding that savings/capital-income should not be taxed. Recently, however, Blackorby and Brett have shown in a model with several desirable features that it can be optimal to tax capital, and they provide a simple yet compelling argument in favor of both savings taxation and capital-income taxation. We use the Blackorby–Brett model (i.e. a model in which the taxation of capital can be justified) to revisit the question of the incidence of capital taxation. We focus on the generational incidence of capital taxation; that is, the incidence on a young generation and an old generation. However, an interpretation in terms of the incidence on "capital" versus "labor" (as is traditional in the tax incidence literature) is also provided.     

What Might Globalisation's Critics Believe?

Critics of globalisation object to many things, some of which can be easily understood within standard economic models, but others of which seem to reflect a view of the world that economists generally do not share. This paper attempts to identify several alternative frameworks for analysis within which some of their criticisms may be understood, with the ultimate aim of extracting testable implications that differ from standard models. Three such alternative models are suggested, all of which focus mainly on the behaviour of owners and managers of corporate capital: an anti‐labour model, in which capitalists are willing to sacrifice some of their own profits for the chance to make labour worse off; a labour‐monopsony model in which capitalists co‐operate globally to increase profits by depressing wages; and an international political economy model in which capitalists use their resources to influence the political process for more than just obtaining import protection. This third framework, which is not spelled out in any detail here, has capitalists seeking policies such as export subsidies and other means of promoting market access, and it also has them influencing the international negotiations that set the rules of international agreements and organisations, such as the NAFTA and WTO. Examples of the latter sort of influence are discussed.     

The Role of the Global Reporting Initiative's Sustainability Reporting Guidelines in the Social Screening of Investments

Social screening of investments calls not only for investment policy and criteria, but also for information about companies, their policies, practices and performance. The Global Reporting Initiative (GRI) and its June 2000 Sustainability Reporting Guidelines have the potential to significantly improve the usefulness and quality of information reported by companies about their environmental, social and economic impacts and performance. The GRI aims to develop a voluntary reporting framework that will elevate sustainability reporting practices to a level equivalent to that of financial reporting in rigour, comparability, auditability and general acceptance. This will be a welcome and efficient supplement to the questionnaires, interviews, press releases, media reports and other sources of information traditionally used for screening in investment decision making – social/ethical and mainstream. The Dow Jones Sustainability Group Index, the Jantzi Social Index and the Innovest EcoValue'21 analytical platform, together with the SRI community, are all likely to benefit from GRI-style sustainability reports. One of the GRI's key challenges is to accommodate the broad variety of disclosure needs and expectations of a wide range of report users and company stakeholders. To maximize the usefulness of the GRI Guidelines, report users, including the SRI community, need to be engaged in the process of developing and refining the Guidelines over time. The GRI Guidelines are emerging as an important instrument in enabling companies to communicate with their stakeholders about performance and accountability beyond just the financial bottom line.
