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.

Full cost accounting: A missing consideration in global tailings dam management

Corporate activities can only be adjusted and new products and services to fight climate change and other climate impacts of the company be developed successfully if managers have relevant information about carbon dioxide (CO2) and other greenhouse gases. This paper explores the notion of carbon management accounting the tools, structures and procedures for managing carbon related information related to corporate activities. To help investigate practice a framework for carbon management accounting is proposed, and the results of interviews with managers in leading German companies about their carbon accounting practices discussed. Forty interviews were conducted in ten listed German companies which have independently received acknowledgement of their good sustainability reporting and sound sustainability performance. With their leading sustainability practices, these companies can also be expected to be leaders in the awareness, collection, measurement, reporting, assurance and use of carbon based information. The results from these exploratory case studies show that even in this selected group of leading German companies, management activities vary considerably in terms of tracking, data keeping and communication as well as volume, location, and organisation of carbon related information flows. The paper draws on the proposed carbon management accounting framework to support both researchers and practitioners in developing information management systems to meet the needs of corporate carbon management.

The role for transdisciplinarity in water accounting by business: reflections and opportunities

Summary: How are education pathways for entry into the accounting profession changing? How are globalisation and new technologies, along with new social and environmental issues, impacting these pathways? And, what can our next generation of graduate entrants expect as accounting roles become increasingly varied and diverse? Each chapter provides fresh insights from professional accounting bodies, practitioners and accounting academics as they openly explore and debate the changing role, education pathways and future needs of professional accountants in an Australian context. Of note, the recurring issue of quality and strategies for upholding the highest standards in accounting education is a shared priority among all contributors.
