The Journal of Econometrics is designed to serve as an outlet for important new research in both theoretical and applied econometrics. The scope of the Journal includes papers dealing with estimation and other methodological aspects of the application of statistical inference to economic data, as well as papers dealing with the application of econometric techniques to substantive areas of economics. Econometric research in the traditional divisions of the discipline or in the newly developing areas of social experimentation are decidedly within the range of the Journal's interests.Annals of Econometrics: The Annals of Econometrics form a supplement to the Journal of Econometrics. Each issue of the Annals includes a collection of papers on an important topic in econometrics, selected by the editor of the issue. Leading researchers have contributed papers on topics such as welfare econometrics of peak-load pricing for electricity, censored or truncated regression models, non-nested models, model specification, econometric analysis of duration data, pre-test and Stein-rule estimators, Bayesian analysis of econometric models etc. The in-depth treatment of specific topics in issues of the Annals will be of value to researchers, teachers and students in applied and theoretical econometrics. All Annals are also available separately.
