09:20 The Piketty Phenomenon

The global debate on taxing wealth, sparked by economist Thomas Piketty and his proposals for improving income equality. Piketty's thesis is  contained in his bestselling book Capital in the Twenty-First Century.

The new book, The Piketty Phenomenon collects New Zealand responses to Thomas Piketty's argument that inherited wealth will always grow faster, on average, than earned wealth.

Three New Zealand economists discuss Piketty's thesis in the New Zealand context – Geoff Bertram is a research associate at the Institute for Governance and Policy Studies at Victoria University; Susan Guthrie is the co-author of the 2011 book, The Big Kahuna with Gareth Morgan which argued for significant tax and welfare reform to redistribute wealth; and Donal Curtin is the former chief economist at the BNZ and now works as a consultant.

There is a panel discussion on the Piketty Phenomenon in Wellington on Thursday evening, 23rd October

11:05 Marty Duda's artist of the week: Vashti Bunyan

Like Rodriguez, Karen Dalton and Lewis, Vashti Bunyan is one of those obscure recording artists who recorded one or two albums 40-plus years ago, dropped out of sight, then was rediscovered in the 21st century. Vashti’s long-out-of print 1970 album, 'Just Another Diamond Day' is now regarded as an English folk classic after it was reissued in 2000. As it turned out, Vashti began her career in 1965 when she was discovered by Rolling Stones manager Andrew Loog Oldham and signed up to be the next Marianne Faithfull. That didn’t work out, and when the Joe Boyd-produced Just Another Diamond flopped, Vashti abandoned her musical career for more domestic matters. Since her re-discovery, she has recorded 'Lookaftering' in 2005 and now, her latest, and most likely, last album, 'Heartleap' has just been released.
