Leo Hurwicz

Leonid Hurwicz: Intelligent Designer is a very enjoyable biography of one of the winners of the economics Nobel for his work on mechanism design (along with Eric Maskin and Roger Myerson). It’s written by his son Michael Hurwicz, and is therefore a genuine labour of love. It’s clear a lot of work has gone into assembling and recounting this tale of an extraordinary life, from his birth to Polish Jewish refugee parents in revolutionary Russia in 1917, via a childhood in Warsaw after the first World War, through being a near-penniless refugee away from his family during the second World War, to his academic career in the US, mostly at the University of Minnesota. His parents and brother survived the war (albeit his father ending up in a Soviet gulag for some time) and also moved to the US.

The book has very little of the economics, and is interesting as biographies generally are for tracing the intellectual history of their subject. Hurwicz’s family put much emphasis on their sons’ education – as the author writes, “Over the centuries, education had functioned as a uniquely portable form of wealth,” for people whose ancestors had often been forced to move. Hurwicz had been taught by or worked for people ranging from Hayek to Samuelson, Oskar Lange to (at the Cowles Commission) Jacob Marschak. He also sounds a delightful person. One of his characteristics – a love of learning many languages – reminded me of my beloved late tutor Peter Sinclair.

I read the book in two sittings. One reflection it prompted was on the unanticipated consequences of total war: their shaping of the character and ideas of a generation of great postwar economists – as the book’s second subtitle puts it, “How War and the Great Depression Inspired a Nobel Economist”; and on the huge stock of human wisdom the US gained by opening its borders, albeit with reluctance, to European refugees.

So you want to be an economist?

I’m late to writing about How to Be a Successful Economist by Vicky Pryce, Andy Ross, Alvin Birdi and Ian Harwood (in the order of the names on the cover). Three things dispose me kindly toward the book before even reading it. First, it’s dedicated to my much-loved, late undergraduate tutor in economics, Peter Sinclair. He’s the reason I’m where I am now. He was dedicated to the formation of future generations of economists and the potential of economics to do good in the world. Second and third, the authors interviewed me, among many others, in their research, and also cite many of the essays in an early book I edited, What’s The Use of Economics.

Having got the disclaimer done, this book, authored by distinguished academics and practitioners, is packed with useful tips and insights (including from the many interviewees)  for anybody from GCSE stage to those just graduating about why they might choose to study economics, the pros and cons, the evolution and limitations of how it’s taught; what jobs are open to economists, what specific and general skills are needed, how to communicate well, and why it matters – and much more. There is also a chapter reflecting on the many critiques of economics and why heterodox approaches are interesting and valuable.

So if you are, or know, a student (in the UK) pondering whether economics is the right thing to do, or having made that choice what they might do next, this is a thoughtful and incredibly useful book.

Metaphysical struggles

I really enjoyed reading Metaphysical Animals: How Four Women Brought Philosophy Back to Life by Clare Mac Cumhaill and Rachel Wiseman. It’s one of two recent books about the quartet Elizabeth Anscombe, Philippa Foot, Mary Midgley and Iris Murdoch, all philosophy students at Oxford just before and during World War Two, and remaining close in the postwar years as they began their scholarly and writing careers. (The other is The Women Are Up To Something by Benjamin Lipscomb, which I haven’t read yet.)

Unsurprisingly, the book is about philosophy rather than economics. I did PPE at Oxford and felt pretty hopeless at the philosophy despite doing ok in exams. We were taught the British tradition – Locke and Hume – and modern linguistic and analytic philosophy – Ayer and Hare. The four women didn’t feature; I’d heard of Irisl Murdoch only, and only for her novels. So I think this implies that the subtitle is perhaps wrong: at least from my perspective, the four might have halted the onward march of reductive positivism in philosophy, but they lost the war.

I was particularly struck by the description of how the shockingly male and misogynist Oxford philosophy establishment reclaimed territory when the men returned from war. “If undergraduate classes before the war had been full of ‘clever young men who liked winning arguments,’ … graduate classes were now led by such men and full of others who were being specifically trained in modern methods and hothoused for a profession that would reward cleverness, quickness and agression.”

Well, hello. Isn’t this the story of economics too? Both disciplines have painfully low proportions of women (and others from backgrounds where people are not automatically taught the confidence needed to put on a show of clever, quick and aggressive). Both are still like this. The culture and make-up are mutually reinforcing. There won’t be a quick solution if any, but the struggle of these four philosophers is inspiring. As is that of all the women of their era who fought to be able to wear trousers if they felt like it, and above all get the same education and scholarly opportunities as the men.

Hayek, in two tomes

Christmas has passed in the usual blur of social over-eating, but I’ve found time to retreat and finish Hayek: A Life 1899-1950 by Bruce Caldwell and Hansjoerg Klausinger. As the authors state, they intended this to be the definitive biography and they have achieved this ambition. Not only do these 700+ pages (plus references etc) constitute only the first part of Hayek’s life, up to his move to the US, the account is based on deep research and familiarity with the mass of sources, primary and secondary, available.

Now ‘definitive’ also has its downsides, only one of which is mustering the strength to hold the book up to read it. Another is that parts of it just aren’t all that interesting: I was held by the story of Hayek’s late-Austro-Hungarian empire childhood but really not at all by his love life. This unfortunately includes his dreadful behaviour in divorcing his first wife after the second world war in favour of his childhood sweetheart, which – as it’s the final chapter of this volume – leaves one with a very negative impression of Hayek the human being. Still, it’s easy enough to skip these chapters.

However, the other downside – at least for one not deeply immersed in Hayek or Austrian School economics – is that it’s quite hard to follow the thread of the intellectual narrative. While ‘The Use of Knowledge in Society‘ is one of my all-time favourite economics articles, and I read ‘The Road to Serfdom‘ back in my undergraduate days, this isn’t my background. So while I did enjoy reading this biography –  particularly the section about Hayek’s intellectual formation in the early 20th century Vienna of logical positivism, and those about his presonal/intellectual rivalries particularly with Keynes during his years in England –  I’d be hard pushed to give a capsule description of what I’ve learned. So I will look forward to Volume 2, the Chicago years, but also to the eventual concise one-volume version of this definitive work.   81Ooi2SOinL._AC_UY436_QL65_

 

Models and Morals

This has been a busy term so I’m behind on my reading, but have recently finished a fine biography, Jan Tinbergen and the Rise of Economic Expertise by Erwin Dekker. I knew little about Tinbergen so was bound to learn a lot from any biography, and this one is genuinely interesting. It has some personal detail but is much more an intellectual history, locating Tinbergen in his historical context. That was not a happy one: the Depression and the Second World War occurred in his early adulthood. The intellectual currents were, of course, fascinating. I had never realised how much Tinbergen was engaged in policy throughout his career. As well as being the founding director of the CPB (which gave me as a thank you gift for a talk a fine bronze bust of Tinbergen earlier this year now in prominent position on my shelves),  he had previously worked at the League of Nations, and continued throughout his career to be heavily engaged in policy. This followed a youth involved in idealistic progressive political movements.

To the extent economists now know anything about Tinbergen, we think of the econometric models for which his Nobel Prize was awarded. The book prompted me to read the Prize Lecture, which is very interesting: “Models constitute a framework or a skeleton and the flesh and blood will have to be added by a lot of common sense and knowledge of details.” He went on to suggest using models to compare different social orderings – communism and capitalism – on a scientific basis; it seems a forlorn hope now but evidently not in 1969. And think about the literary illustration of the equivalance of perfect markets and perfect planning in Francis Spufford’s wonderful book Red Plenty.

Dekker comments that Tinbergen found it irritating that this work from the 1930s was remembered rather than his later thinking about the institutional framework within which economies operate – the ‘Ordnung’ (the book uses the German word). I found particularly interesting a chapter titled ‘The Expert in the Model, the Economist outside the Model’, portraying Tinbergen’s effort to reconcile the fact that he had put policymakers inside his model of the how the economy operates with his simultaneous view that economists could nevertheless analyse from above  – ‘the view from nowhere’ – how the system then changes and can be controlled. The chapter uses the Lucas critique to analyse this in a macro context. It’s one of the themes of my Cogs & Monsters.

I also greatly enjoyed the chapter ‘Measuring the Unmeasurable: Welfare and Justice’. Dekker writes: “Tinbergen was mostly silent on philosophical matters. …. One of the very few exceptions are his reflections on ‘measurement in the human sciences.” He saw measurements as a vector for changing behaviour, and in addition saw the purpose of economic measurement as measurement of economic welfare. His was not a positivist view, but rather a moral one: economic policy had a deep societal purpose.

The book is quite long but the 400 pages zipped by. Tinbergen was clearly a fascinating person and deserves to be better appreciated by the Anglophone dominated economics profession. This biography serves him well.
