Mr Fixit?

Every year on 14 February, chocolates, flowers, gifts and cards are exchanged between loved ones around the world, all in the name of St. Valentine. But do any of us even know who St. Valentine is anymore or have we just got caught up in another 21st Century ‘Hallmark holiday’?

Even Wilko Johnson's skull is stripped to brutal basics. Bushy grey eyebrows hood the dent in his bald eagle forehead; manic eyes stare down the crowd. In the 1970s, Johnson's band, Dr Feelgood, helped scorch a path for punk. Last year, a documentary by Julien Temple, Oil City Confidential, showed that the largely forgotten guitarist is still magnetically charismatic, though haunted by the death in 2004 of his childhood sweetheart and wife, Irene. Tonight, the success of the film seems to have resurrected not only Johnson's career, but also his spirit.

The economist and science policy adviser Chris Freeman was one of the most original and influential economists of the late 20th century who combined the radical political outlook that inspired him (he refused government honours) with advising unashamedly pro-capitalist governments on technological policy.

Outlook Jérôme Kerviel seems to have become a sort of white-collar Raoul Moat. Like the latter, the French rogue trader has been all but lionised for a series of frankly contemptible acts. Now it's true that unlike the execrable Moat, Kerviel didn't kill anyone. No, he just burnt his way through a staggering €5bn of other people's money, almost bringing down Société Générale and everyone who sailed within her.

The Business Secretary spots a news vacuum and pleases all of the people all of the time

Vince Cable stepped up his attack on the City of London with a searing attack on "spivs and gamblers" in the Square Mile whose greed had taken the economy to the edge of disaster.

"People say I'm miserable," Vince said, to laughter. "But this is my happy face." I had forgotten how useful it is, that thing he has on the front of his head. Such an unpromising arrangement of features: a mouth like a mule's and the guarded, pain-filled eyes. It could play one of the tramps in Waiting for Godot.

Outlook We can surely forgive Vince Cable one afternoon of political grandstanding. In opposition, Mr Cable was the LibDems' showman-in-chief, a far more effective and respected critic of the Labour government than the Conservatives with whom he now works. How the hair-shirt of office must have chafed these four long months. Even when his Tory colleagues asked Sir Philip Green, that master of tax avoidance, to work for coalition, the Business Secretary felt compelled to bite his tongue.

For those of us disturbed by the way that Bob Diamond, the new boss of Barclays, has, one way or another, made around £95 million from his bank, an institution virtually bust a couple of years ago, Ha-Joon Chang has a couple of "things" to say. Specifically, Thing Number 13 in this myth-busting and nicely-written collection of essays: "Making rich people richer doesn't make the rest of us richer"; and Thing Number 14: "US managers are overpriced." Diamond has spent most of his career on Wall Street, and much the same applies to the UK.

Nights of debauched greed delay a suicide mission

His two sons are currently battling it out for the Labour leadership. But who was Ralph Miliband – and how would he have cast his vote? Andy McSmith investigates an inspirational political parent

Ha-Joon Chang, the new kid on the economics block, is out to bust open a few myths

Prof Geoffrey Miller is on a mission to redefine how we think about marketing. Through the discipline of evolutionary psychology, he examines and dispatches the current marketing paradigms. These he identifies as either conservative (human nature plus free markets necessarily equals consumerist capitalism) or radical (consumerist capitalism occurs as a result of oppressive institutions and ideologies impressing themselves on nascent minds). While such alternatives may be unfairly cast as straw men, Must-Have is a thought-provoking analysis of how marketing really works and its relationship to our ancient psychological traits.
