The fact that radio is so hopeless at delivering data makes it an uncluttered medium, offering the basic story without the detailed trappings. But it does mean that if data is important, radio is probably not your place.

Interestingly, human irrationality is a hot topic in economics at the moment. Behavioural economics it's called, on the cusp of economics and psychology.

Put simply, behavioural economics argues that human beings' decision-taking is guided by the evolutionary baggage which we bring with us to the present day. Evolution has made us rational to a point, but not perfectly so. It has given us emotions, for example, which programme us to override our rational brain and act more instinctively.

Personally, I don't see old economics and behavioural economics as opposed. It is useful to assume people are rational as a good approximation to their long term behaviour, but it would be unwise not to think how in practice their behaviour may deviate from that simplifying assumption.

But beginners to the World Economics Forum have to understand there is no single Davos experience, and there is no single Davos community either. There are numerous tribes who interact only at a minimal level.

Some people harbour an awkward clash of feelings - homosexual attraction on the one hand and shame or embarrassment about that attraction on the other. It is well known that the mind struggles to sustain conflicting views.

All socio-political phenomena in the U.K. come laden with the baggage of a class-based theory or two attached to them. In the case of gay Tories, there is one particularly silly variant of the category, which asserts that gayness is bred in public schools and thus fits with Conservatism like hand in glove.

I've always been scared of advertising folk. I've met them at parties and I've been to their offices and I've always found them intimidatingly cool. At one company I visited, they held their meetings in a caravan that had somehow been installed in the place, a rather more exotic place to gather than the typical BBC glass box.

Even the 'Today' programme involves a balance between the worthy-but-heavy items with the worthless-but-entertainingly-light ones.

It's not a bad idea to occasionally spend a little time thinking about things you take for granted. Plain everyday things.

A chair's function is not just to provide a place to sit; it is to provide a medium for self-expression. Chairs are about status, for example. Or signalling something about oneself. That's why the words chair, seat and bench have found themselves used to describe high status professions, from academia to Parliament to the law.

Once we are fed, heated, housed and healthy, our extra consumption inevitably has an element of luxury about it. And once luxury enters the scene, the practicalities are in trouble, as women who wear expensive stiletto heels can testify.

We are more likely to cheat if we see others doing so. We tend to conform to accepted norms of reasonable behaviour, rather than adhere to strict rules.

But sometimes it's good to dare yourself to do the unthinkable. And rather than stand in front of an audience with no clothes on, I decided to have a go at stand-up comedy.

Now I can broadcast to an audience of several million people on the 'Today' programme. I can talk about the day's news. But on radio, believe it or not, we have notes and scripts. And while we might ad lib the odd wryly amusing asides, they come at the frequency of a suburban bus. About one every 90 minutes.

Being funny, it turns out, is like being a bank. It's a confidence trick. As long as everyone believes in you, you are fine.

For industry to settle in a country, you first need electricity; for electricity, you need some trained workers; for trained workers, you need some schools; for schools you need some money; for money, you need some industry.

As it happens, I have personally been something of an enthusiast for the London Olympic games, mainly on the grounds a) that a bit of wasteland will be made nice and b) that it tends to make everybody happy that their country should be the centre of world attention for a couple of weeks in their life.

Art can help a town by attracting a certain Bohemian population that adds life to the bars, character to the streets and a buzz to the name. Employers may then follow. But art can't do much if every town does it. There aren't enough Bohemians.

I rarely come away from presenting the 'Today' programme without some sense of regret. There is always some question that I should have asked, or some point that I should have made. This is annoying but not surprising. Perfection is hard to achieve in a three-hour live programme.

Even though disciplined sleeping habits and the adrenalin of live radio ensures that we are very awake while on duty, there is evidence of a phenomenon called circadian desynchronosis which causes one's brain to function slowly at those times of day when it thinks it should be asleep, regardless how wide awake the body is.

It is no wonder that bank capital is regulated. When borrowing and lending is profitable, it is tempting for banks to scale up their operations and to borrow and lend too much in relation to their capital, in effect reducing the effectiveness of the potential capital cushion.

We escaped the last big bursting of a bubble - the dotcom bubble - with a relatively light U.S. recession. On that occasion, the world economy found its way back on track fairly quickly.

Interest rate cuts have an effect in stimulating an economy by directly or indirectly making someone, somewhere, spend more than they otherwise would. That extra spending increases demand and ensures that we all carry on with work to do, without us having to slash our prices or our wrists.

In principle, there are only three main components of spending that much matter to monetary policy: consumer spending, business investment and exports and trade.

My instinct is to assume that we consumers are an inconsistent bunch. We like competition if it delivers low prices, but grumble if it delivers the bad news that prices need to go up.

We Brits print banknotes out in Debden in Essex, and have contracted it out to the private sector. Here in the U.S. it is a government operation right in the heart of Washington next door to the Holocaust Museum.

We all know that Americans love their statistics - in sport, obviously. And in finance too.

Black Friday is not another bad hair day in Wall Street. It's the term used by American retailers to describe the day after the Thanksgiving Holiday, seen as the semi-official start of Christmas shopping season.

For years, we've grown dependant on American consumers as the world's spenders of last resort. They've kept Europe out of recession, allowed China to industrialise, and prevented global deflation. But at the same time, they've not been looking after their own futures.

Most people hugely underestimate the amount of 'empty space' we have in our country. Fly over the U.K., and you see that human settlement does not fill up the U.K. at all. It accounts for something of the order of 15 per cent of the landmass.

Britain, however, has ended up specializing in the ones you don't see as much of: defense aerospace, making drive shafts for cars, pills and drugs, designing chips that go into 94 percent of the world's mobile phones.

It's amazing, if you know what you want to say, how fast it is to write.

Someday we'll look back on this moment and plow into a parked car.

Although being economics editor sounds impressive, it does not mean I actually edit anything. It mainly reflects two decades of title-inflation at the BBC, which has given ever more status to senior reporters, presumably because it is cheaper to do that than to offer higher pay.

Nice guys finish last, but we get to sleep in.

Men don't know much about women. We do know when they're happy. We know when they're crying, and we know when they're pissed off. We just don't know in what order these are gonna come at us.

I don't keep it secret that I live with my partner Gio. I'm very proud of my gayness. But there is lots I wouldn't want the press to write about me... it is a matter of regret that being gay is the most interesting thing about me.

One of the key problems is that the Germans know what they do because everywhere they go there's a 'made in Germany' label on it - they can feel proud of Volkswagens and Audis and Mercedes.

Reducing every issue to an argument can become stale but it's often a very good way of clarifying issues.

I don't want to sound like 'chirpy Evan' who's just bouncing around with his unrealistic views and doesn't understand what's going on.

What comes with a job as a staff member of the BBC is a certain self-censoring that you get utterly used to. You don't say everything you think. You hold back on some things.

I swing both ways. I can see things from a kind of conservative point of view and from a more socially liberal or left-wing point of view.

Mistakes are nothing to be ashamed of.

It doesn't annoy me but I think of myself as a presenter who is gay, rather than a gay presenter. It's a subtle distinction, but that's how I view it.

The Germans are clear about what they do - cars and machine tools; the Japanese are clear about what they do - electronics; the Chinese are clear about what they do - they're the workshop of the world.

If you're not making some mistakes, it probably means you're not trying hard enough.

There is a strong link between the following three things: exporting, manufacturing and the degree of saving by the population. It's complicated, but if the population doesn't save, the economy will not tend to export as much, and if it doesn't export as much, it won't manufacture enough.

When a population saves a lot, the funds are invested outside the country as well as inside. If the Japanese invest in the United States, it pushes their exchange rate down and makes their manufacturing more competitive.

For me, the main principle for broadcasters has to be that if people stand to benefit from an interview, they should be prepared to face some downside as well.
