Nobel-winning US economist Joseph Stiglitz and Swiss anti-corruption expert Mark Pieth said August 6, 2016 that a dispute over transparency had prompted them to quit a panel on reforming Panama's finance sector. The pair quit the committee -- set up by the Panamanian government in a declared bid to reform the country's tarnished financial services -- on August 5, 2016. / AFP PHOTO / RODRIGO ARANGUARODRIGO ARANGUA/AFP/Getty Images
