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.

Implementation of sustainable development goals: The role for business academics:

Although sustainable and responsible investment (SRI) has quite recently become a hot research topic, scarcely any systematic research has been paid to the performance of this non-conventional approach to investment during the financial crisis that emerged in mid-2008 when the resilience of the financial markets was sorely tested. Such real-world resilience in practice is the subject of the current research which tests whether environmental, social and governance screens provides ethical investors with adaptive resilience in bull and bear market conditions by focussing on the SRI equity index of one of the most active markets in Europe in terms of ethical investment, the FTSE4Good-Ibex in Spain. Multivariate Generalized Autoregressive Conditional Heteroskedasticity (M-GARCH) analysis indicates that ethical investors in the equity market examined with evidence that greater resilience in severe business cycle shocks could be attributable to SRI by companies. Although limited to a single country study, the results have implications for investors seeking resilience in crisis: when individual values and beliefs towards sustainability tie with personal investment strategy, the end result is adaptive financial resilience, social well-being and environmental defence.
