Christopher Colclough was my first graduate student in 1967. He had come from Bristol with his first degree and the Powesland Memorial Prize in economics. We would have weekly supervisions in what was then the Department of Applied Economics – myself, Chris and Udi Gachaga from Kenya. I am not sure who learned the most and from whom, but it was always stimulating and enjoyable. Soon it became obvious that Chris had real talent for thoughtful economics and careful analysis, and he wanted to study further. It didn’t take long before we had agreed that he would stay on for doctoral study.
