Economists are split over how long the government has to rein in the world's biggest debt burden, a Bloomberg News survey shows, adding to a debate on whether the government should keep ratcheting up the sales tax.
Eleven of 34 analysts said the government has four years or less to put fiscal policy on a sustainable path and avoid a crisis, while seven said it has more than 10 years.
BNP Paribas SA and Credit Suisse Group AG were among five saying it's too late to avert one. UBS AG says chances of a fiscal crisis are remote.
