The seminars on “Recent Research at Warwick University” are specified in terms of five three hour sessions. Each session is based on a particular topic, and papers for that session consist of one ideas paper and one or more research papers. The ideas papers cover the broad area in a popular style, the research papers involve empirical research related to the ideas. At the moment it is my plan to present materials from the ideas papers, referring to some of the specified research articles. However, I will respond to the audience should a different manner of presentation be appropriate.
