Often, MEL includes a special section under the heading ‘Policy Perspectives.’ Papers here, often solicited ones, emphasise strategic policy implications rather than scientific rigour in a strict sense. Papers in Policy Perspectives are not subject to peer review; this results in speedier publication. Papers submitted to MEL are submitted for both sections at the discretion of the Editors. Authors not wishing to have their papers considered for Policy Perspectives should state this in the Cover Letter.
