Tax havens have no justification, say top economists, calling for their abolition

More than 300 economists, including Thomas Piketty, are urging world leaders at a London summit this week to recognise that there is no economic benefit to tax havens, demanding that the veil of secrecy that surrounds them be lifted.
UK Prime Minister David Cameron agreed to host the summit nearly a year ago, but the event is in danger of simply turning a spotlight on how the British government has failed to persuade its overseas territories to stop harbouring secretly stored cash.
British officials are locked in negotiations with the crown dependencies and overseas territories, trying to persuade them to agree to a form of automatic exchange of information on beneficial ownership of companies. So far the overseas territories have only agreed to allow UK law enforcement agencies access to a privately held register of beneficial ownership, but the automatic exchange agreement would give a wider range of countries access to information on the ownership of shell companies.
Many overseas territories including the Cayman Islands are resisting the idea, and their attendance at the summit is in doubt.

Other signatories include Nora Lustig, professor of Latin American economics at Tulane University, as well as influential experts who advise policymakers, such as Jeffrey Sachs, director of Columbia University’s Earth Institute and an adviser to UN secretary general Ban Ki-moon, and Olivier Blanchard, former IMF chief economist.
In total 47 academics from British universities, including Oxford and the London School of Economics, have signed the letter which argues that tax evasion weakens both developed and developing economies, as well as driving inequality.
