In this book, Andrew Harvey sets out to provide a unified and comprehensive theory of structural time series models. Unlike the traditional ARIMA models, structural time series models consist explicitly of unobserved components, such as trends and seasonals, which have a direct interpretation. As a result the model selection methodology associated with structural models is much closer to econometric methodology. The link with econometrics is made even closer by the natural way in which the models can be extended to include explanatory variables and to cope with multivariate time series. From the technical point of view, state space models and the Kalman filter play a key role in the statistical treatment of structural time series models. The book includes a detailed treatment of the Kalman filter. This technique was originally developed in control engineering, but is becoming increasingly important in fields such as economics and operations research. This book is concerned primarily with modelling economic and social time series, and with addressing the special problems which the treatment of such series poses. The properties of the models and the methodological techniques used to select them are illustrated with various applications. These range from the modellling of trends and cycles in US macroeconomic time series to to an evaluation of the effects of seat belt legislation in the UK.

What makes organizations so similar? We contend that the engine of rationalization and bureaucratization has moved from the competitive marketplace to the state and the professions. Once a set of organizations emerges as a field, a paradox arises: rational actors make their organizations increasingly similar as they try to change them. We describe three isomorphic processes-coercive, mimetic, and normative—leading to this outcome. We then specify hypotheses about the impact of resource centralization and dependency, goal ambiguity and technical uncertainty, and professionalization and structuration on isomorphic change. Finally, we suggest implications for theories of organizations and social change.

The iron cage revisited: Institutional isomorphism and collective rationality in organizational fields (Chinese Translation)

Purpose – The paper aims to discuss the current development of sustainability accounting research, the identification of critical and managerial paths, and to assess of the future of sustainability accounting and reporting.Design/methodology/approach – The paper is a review of recent literature in sustainability accounting.Findings – Assessment of recent literature leads to the conclusion that both management decision making, through problem solving and scorekeeping, and a critical approach, through awareness raising, contribute to the development of sustainability accounting and reporting; however, the development of sustainability accounting and reporting should be orientated more towards improving management decision making.Originality/value – The paper is a systematic review of recent research developments in sustainability accounting.

Contemporary Environmental Accounting: Issues, Concepts and Practice

This article develops a comprehensive framework for environmental management accounting (EMA) linking business actors and EMA tools. The proposed framework provides structure for managers to understand and assess the variety of environmental management accounting tools that have been developed to date, with the intention of encouraging their adoption. The framework systematically integrates two major components of environmental management accounting — monetary environmental management accounting (MEMA) and physical environmental management accounting (PEMA). It highlights the past/future and short/long-term time dimensions of the different tools, and the regularity of information generation, before concluding with a brief discussion about choice of the most important EMA tools.
