Tim Harford signs up

Tim Harford, author of "The Undercover Economist" and a columnist for the Financial Times, joins the Pigou Club:

Consider the problem of climate change: a centralised regulatory approach here would be a catastrophe, lashing out at easy political targets such as SUVs or cheap airline travel. But pure laissez-faire will not save the planet either. A predictable tax on carbon would unleash a lot of world-saving creativity at minimum cost.

By the way, the Club now has its own Wikipedia entry.
