Abstract
Macro Modelling Notes is a new section of the Review, which we hope will appear on a regular basis. It will contain a small number of very short papers that have arisen from applied macro modelling work at the Institute or elsewhere. In the course of building and operating macro models, a large amount of information is used and produced that may never enter the public domain. This may be because the information is not substantial enough to justify a whole journal article, or because it is specific to the practice of using a macro econometric model. However this information is often of general interest to other economists, and is nearly always helpful to other macro modellers. This section is designed as an outlet for information of this kind, which might otherwise not be published in any readily accessible form.
The three notes below provide three different examples of this type of note. The first involves econometric practice, and shows how long-run standard errors can be simply derived using standard regression techniques. The second presents some econometric results on export pricing obtained during normal 'model maintenance' of our world model GEM. The third considers the problem of setting terminal dates for a consistent expectations model.
This new section of the Review is designed as a vehicle for all UK and overseas macro modellers, and therefore outside submissions are strongly encouraged. Submissions must be of about the length of the notes shown here, and contain relevant material that does not form part of a larger article soon to be published. Unlike Review articles, these notes will not normally be refereed, but the Editorial Board may consult expert advice when necessary.
