Jon Moulton is the founder and chairman of the private equity firm Better Capital LLP.

He says we need more failure if we are to overcome the recession.

Jon says failing countries, failing banks and failing companies have not been allowed to go bust - which is what has previously happened. The Darwinian element of the economy is not working.

This means bad business models are allowed to keep operating, and this keeping productivity down.

Jon appeared on The Bottom Line which is broadcast on BBC Radio 4 and BBC World Service. Listen again via the download or watch it on the BBC News Channel.
