Harper, Malcolm2009-02-042009-02-041987School of Management, Working Paper no. SWP/12/87http://hdl.handle.net/1826/3138The majority of the papers submitted for SMD were of a high quality, as were the presentations. It is invidious to pick out only five, but I felt those which have been included in this sample, particularly deserved a wider circulation than just me. There are many others of similar quality, but some were too long, too specialised, confidential or plain illegible.enWorking Paper
