Next week the Chancellor George Osborne will unveil his spring budget to the House of Commons as speculation grows over whether he's likely to make any cutbacks or if he's course to pay down the nation's debts. Mr Osborne is saying nothing although he's dropped plans to end or alter tax relief on pension contributions in a move which campaigners believe is a missed opportunity to help the low paid. Yet regardless of what the Chancellor does on Wednesday, his calculations will have been influenced by an econimic model that critics claim is flawed and past its sell by date. Neo-classical economics may be Treasury's guding light, but has it done more harm than good? Is it time to look at the alternatives? Juliette Foster was joined in the studio by Professor John Weeks, Share Radio's regular economics commentator, and Professor Steve Keen of Kingston University London. Steve is also the author of the best-selling book "Debunking Economics".
