TOKYO (AFX-ASIA) - The Bank of Japan's policy board members forecast year to March 2003 real GDP will come in at between minus 0.5 pct and plus 0.1 pct, using a narrow range, and minus 0.5 pct and plus 0.2 pct, using a broad range. The forecasts show a mild improvement compared with estimated ranges made in October of minus 1.1-plus 0.1 pct using a narrow range, and minus 1.7 to plus 0.2 pct in a broad range. The broad range incorporates the forecasts of all members of the policy board, while the narrow range excludes the highest and lowest estimates.
