Thanks for the opportunity to give this lecture and, at the same time, mark my retirement from SOAS after twenty-seven years, following twenty years at Birkbeck, and fifty years since first studying economics as a graduate student, having completed a first degree in mathematics. Back in 1969, Jim Mirrlees, then Professor of Economics at Oxford, visited the Maths Institute to recruit third-year undergraduates to be funded to take a two-year postgraduate course in economics. I was one of the lucky ones to benefit from his view that a degree in mathematics was more important than one in economics for his purposes. Within a week, I was participating in a weekly research seminar with the leading mathematical economists organised by Mirrlees, reflecting the ease of transition from maths to such economics. Of course, sorry for the name dropping and more to come as this is an occasion to indulge myself, Mirrlees was later to win a Nobel Prize for devising optimal taxation systems (in which all conscientiously pay their taxes).That's how my economics began, and sorry that I have taught so few of you as alumni in our audience today, as I have scarcely taught other than at postgraduate level, and especially focused upon research students, with fifty-one of my own having completed, and hundreds of others have passed through my hands as I have spent most of my career as a research student tutor. Indeed, I can identify as past supervisees, ten professors, twenty-one lecturers, fourteen researchers, four I am now unable to trace, and two whom I am unsure how to categorise! 1 Now, from my title, I suspect you expect me to entertain you with Fake News and Trumponomics. Not at all. I want to talk about my own career and had to find a way to frame it, a peg or theme on which to hang it, a sort of literature survey of myself (a private joke with my Phd students). 2 I thought it might be interesting to see how my works, thirty books and three hundred articles or so, have stood up to the test of time, against my major theme that mainstream economics is a major and longstanding purveyor of post-truth. Here, it is important to note that the current vogue of pointing to fake news, post-truth, etc, is itself a 1 Note that research students, and colleagues, have been a rich source of joint research and collaboration. But, with one exception, apart from referencing publications, I have refrained from mentioning individuals in what follows despite a huge debt of contribution and gratitude (hopefully deservedly felt in both directions). 2 I have had the chance on two previous occasions to write about my life as an economist, see Fine (2001a and2012a). In the former, I was tickled to realise I was the youngest living contributor!
