The Italian economic performance outlook for 2013 worsens, when the gross domestic product is likely to drop more than the country's government originally predicted, the President of the statistical office Istat Enrico Giovannini said on Friday. The initial outlook said that the nation's GDP would decline by 1.3% in 2013, the new estimates says the forecast is too upbeat. The Bank of Italy projected a 1% contraction for this year.
