When does the irrational exuberance of markets lead to asset price bubbles? A question pondered by Dr. Alan Greenspan, former Chairman of the US Federal Reserve, in December 1996. But the phrase "irrational exuberance" - a polite way of warning that the markets were in danger of overheating - turned out to rather be prescient. This was after all the dotcom era when anything with dotcom behind its name - no matter how flawed the business plan - was a licence to print money. When the tech bubble eventually burst investors took heavy losses while Greenspan looked for a way through the morass. The markets gradually picked up, money flowed in and the public felt rich: Alan Greenspan had worked his magic and restored America's Feel Good factor. When he retired in 2006 he was lauded as a genius, a tough act to follow...yet when the global financial crisis erupted, the fault lines were traced back to him. The hero was now a villain! So why did it go wrong? Sebastian Mallaby is a journalist and author of the book 'The Man Who Knew: The Life and Times of Alan Greenspan'. He joined Share Radio's Juliette Foster in the studio.

So why have African countries fallen off the rails and what do they need to do to get back on track? Doctor Howard Stein is a Professor in Afro American and African Studies at the University of Michigan. He joined Share Radio's Juliette Foster in the studio with Professor John Weeks, Share Radio's regular economics commentator.
