Panglossian finance

Disagreement among practitioners of the dismal science

As David Blanchflower argued in his first economics column for the NS, the crash of autumn 2008 wasn't just a failure of banking practice -- it was an intellectual failure, too. The collapse of Lehman Brothers just over a year ago wasn't just an indictment of hubris and greed on Wall Street; it was also "a body blow to those economists around the world who had designed worthless mathematical models, based on unrealistic assumptions that they then used to convince themselves that a recession of this kind could never happen again".

Blanchflower's magisterial dismissal of "useless economic models" echoed something the Nobel Prize-winning economist and New York Times columnist Paul Krugman had a written a couple of weeks earlier. Under the title "How Did Economists Get It So Wrong", Krugman chastised economists for "mistaking beauty for truth" -- for allowing themselves, that is, to be seduced by abstract mathematical models and an "idealised vision of an economy in which rational individuals interact in perfect markets". The only problem is that perfect markets have never existed and never will exist -- pace what Krugman nicely calls "Panglossian finance" -- and the sooner economists "learn to live with messiness", the better.

That's a very Keynesian view, of course. As Peter Clarke shows in his book Keynes: the 20th Century's Most Influential Economist (reviewed in the NS by Andrew Gamble), a recognition of the pervasiveness of uncertainty was a very important part of Keynes's vision. Keynes wrote that the "fact that our knowledge of the future is fluctuating, vague and uncertain, renders wealth a peculiarly unsuitable subject for the methods of the classical political economy". In other words, the market doesn't always get it right; in fact, very often it gets it catastrophically wrong.

Compelling stuff -- but some of Krugman's fellow economists have objected to being handed such low marks, among them John H Cochrane of the University of Chicago, who returned fire in an article entitled "How Did Paul Krugman Get It So Wrong?". Cochrane boils Krugman's piece down to the thesis that (in Krugman's own words) "Keynesian economics remains the best framework we have". He then charges Krugman with making a number of incompatible arguments.

For instance, in Cochrane's view, it is only because Krugman caricatures the so-called "efficient markets hypothesis" that his call for an economics that "recognises flaws and frictions" and "incorporates alternative assumptions about behaviour" has any force at all. Cochrane is caustic about this:

I say, "Hello, Paul, where have you been for the last 30 years?" Macroeconomists have not spent 30 years admiring the eternal verities of Kydland and Prescott's 1982 paper. Pretty much all we have been doing for 30 years is introducing flaws, frictions and new behaviours, especially new models of attitudes to risk, and comparing the resulting models, quantitatively, to data. The long literature on financial crises and banking which Krugman does not mention has also been doing exactly the same.

Further, according to Cochrane, "Krugman argues that 'a more or less Keynesian view is the only plausible game in town', and 'Keynesian economics remains the best framework we have for making sense of recessions and depressions'. One thing is pretty clear by now, that when economics incorporates flaws and frictions, the result will not be to rehabilitate an 80-year-old book." Ouch! Cochrane goes on: "A science that moves forward almost never ends up back where it started. Einstein revises Newton, but does not send you back to Aristotle. At best you can play the fun game of hunting for inspirational quotes, but that doesn't mean that you could have known the same thing by just reading Keynes once more."

Cochrane is taking it for granted here that economics is a science, in the way that physics is -- that's the point of the gibe about Einstein, Newton and Aristotle. And I think that may be where the disagreement between Krugman and Cochrane is most profound. For, as Krugman surely knows, Keynes regarded economics as being a moral as much as a mathematical science. This is one of the central insights of Robert Skidelsky's recent book about Keynes, also discussed in the review by Andrew Gamble mentioned above: "One of the greatest defects of economics today is that it has become a branch of applied mathematics. [But] Keynes thought of economics as part of the human discourse."

Britain's diversity crisis starts with its writers. Here's why

What happens on the casting couch draws the headline, but the problem starts on the page, says James Graham. 

I’m a playwright and screenwriter, which – pertinent to the issues we’ll be discussing in this enquiry – still feels weird to say. I get embarrassed, still, saying that, in a taxi or hairdressers. I don’t know why I still carry that insecurity about saying I’m a writer, but I do, because it sounds like I’m lying, even in my own head.

Obviously I’m completely biased, and probably overstating the influence and importance of my own profession, but I think so many of the problems surrounding lack of representation in the performing arts start with writers.

If we aren’t encouraging and generating writers from certain communities, classes or backgrounds to tell their stories, to write those roles, then there’s not going to be a demand for actors from those communities to play them. For casting agents or drama schools to prioritise getting diverse actors on stage. We need to create those plays and TV dramas –like the ones that I grew up with. I didn’t have any access to much theatre until I was fifteen, but I did have Boys From the Black Stuff, and I did have Cracker, and I did have Band of Gold. I think the loss of those regional producing bodies – Central, Granada – now all completely centralised into London, means that we just tell less of those stories. I remember a TV show called Boon – anyone? – which was set in Nottingham, and I would see on the TV streets I’d walked down, and think, Oh my God, that actor is walking down a street I’ve walked down. That sounds like it’s insignificant. If you’re from a town that is deprived, that feels ignored, it isn’t.

I was very lucky that at my school (which was, at the time, the largest comprehensive school in the country), from the headmaster down to the drama teachers, everyone just believed that working class kids should do plays. Be in plays, read plays, perform plays to the community. Both inside the curriculum of the school day, and outside it – drama teachers dedicating their time to staying behind. Our head of drama identified a group of us who clearly had a passion for it. We weren’t likely thesps. One lad’s entire family were made unemployed when the pit closed. Many lived on the big council estate. My parents and step-parents worked respectively in warehouses, the local council, or as the local window cleaner (incidentally, my first real job. Which I was terrible at).

Our drama teacher was encouraged and determined enough to launch the first ever Drama A-Level in our school. Based on that, about 10 or 12 of us got the confidence – or arrogance – to take our own show to the Edinburgh Festival. We were 16 or 17, and the first people in our community to ever go to visit the festival. We did a play up there, and after that, a psychological unlocking happened, where I thought: maybe I could do a degree in drama (it was the first time I had ever thought to do so) at university (the first in my family to go. Well, joint-first. My twin sister went on the same day, but I walked into my digs first).

I enrolled in drama at Hull University. A high proportion of my peers were middle class. A higher proportion from London or the South East. They talked often about institutions I had never heard of. They were talking about the National Theatre: I didn’t know we had a national theatre that my parents had been paying tax for that I had never been to. Many had performed with the (again, apparently) ‘National’ Youth Theatre, also in London. Paul Roseby, also on this panel, has made such leaps forward in getting the NYT producing in regional venues, and making auditions possible for people across the UK, but unfortunately, at the time, that wasn’t the case for me – and I was the ideal candidate to be in the National Youth Theatre.

I started writing because I had the confidence after I read texts by people like Jim Cartwright, Alan Bennett, John Godber, Alan Ayckbourn: Northern writers, working class writers that made me think it wasn’t just something that other people do.

After returning home, and working at local theatres, I moved down to London. I had to. The major new writing producers are there. All the TV companies are there. The agents are there. I was lucky to find support in a pub fringe theatre – though the economics meant there was no money to commission, so I wrote plays for free for about four years, that would get produced, and reviewed in the national press, while I worked various jobs in the day and slept for a time on a mate's floor. The first person to ever pay to commission me to write a play was Paul Roseby of the National Youth Theatre. I’m now very lucky to be earning a living doing something I love. In a way, compared to actors, or directors, it’s easier for writers who don’t come from a background that can sustain them, financially, in those early years. Your hours can be more flexible. Yes, it was annoying to miss rehearsals because I had a shift in a call centre, but it was still possible to do it. If you’re an actor or director, you’re fully committed. And if you’re doing that for nothing, there starts to be cut-off point for those from backgrounds who can’t.

I’m sure that local and regional theatres are the key to drawing in talent from less privileged backgrounds. But the range of national arts journalism that cover work outside London has been so significantly reduced. In our little echo chamber a few weeks ago, we theatre types talked about Lyn Gardner at the Guardian. Her coverage has been cut, which is very directly going to affect her ability to cover theatre shows outside of London – and so the self-fulfilling cycle of artists leaving their communities to work exclusively in London takes another, inevitable, turn.

I am culpable in this cycle. I have never done a play at the Nottingham Playhouse, my local producing house growing up – why? Because I’ve never submitted one, because I know that it will get less national press attention. So I just open it in London instead. That’s terrible of me. And I should just bite the bullet and say it doesn’t matter about the attention it gets, I should just go and do a story for my community. And if I, and others, started doing that more, maybe they will come.

I also want to blame myself for not contributing back to the state schools that I come from. I really really enjoy going to do writing workshops with kids in schools, but I would say 90 per cent of those that I get invited to are private schools, or boarding schools, or in the South of England. Either because they’re the ones that ask me, because they’re the ones who come and see my shows in London and see me afterwards backstage, or because they have the confidence to email my agent, or they have the budget to pay for my train ticket. Either way, I should do more. It would have helped the younger me so much to meet a real person, from my background, doing what I wanted to do.

I don’t know how to facilitate that. I take inspiration from Act for Change, creating a grassroots organisation. I know that there is a wealth of industry professionals like me who would, if there was a joined-up structure in place that got us out there into less privileged communities, we would on a regular basis go to schools who don’t get to meet industry professionals and don’t unlock that cultural and psychological block that working class kids have that says, that is not for me, that is something that other people do, I would dedicate so much of my time to it. That’s just one idea of hopefully better ones from other people that might come out of this enquiry.
