To reduce the appetite for speculative risk, Turner is promoting a levy on financial transactions to divert money to the poor and support efforts to address climate change. The so-called Tobin tax is named after the late U.S. economist James Tobin, a Nobel laureate who proposed a surcharge on currency trading to deter speculation.
“I believe in markets; I believe in enterprise,” says Turner, who numbers Franklin D. Roosevelt and British economist John Maynard Keynes among his personal heroes. “But I have always believed that market economies will not of themselves combine that with environmental sustainability or with a reasonably just and good society. I believe that capitalism needs to be saved from itself.”
