8. Statistics vs. Forecasts Statistics vs. Forecasts Flash and Advance estimate are just forecasts, not statistics. They are statistics: They still depend on the source data and a reasonable inference of the current economic situation based on various quantitative and qualitative information. Accuracy vs. Rapidity Accuracy vs. Rapidity The Flash or Advance estimate is premised on the sacrifice of statistical accuracy. Rapidity is more important: A rapid but a slightly inaccurate estimate is much better than the acc urate statistics after a long time lag in a new era. Transparency vs. Policy priority Transparency vs. Policy priority It is problematic that why is the Flash estimate provided only to monetary policy committee Policy priority should be emphasized: Its public release should be put off until its statistical stabil ity is clearly proven. It is desirable for the public good to provide it to policymaker. Extra burden vs. User friendly Extra burden vs. User friendly The compilation of the Flash or Advance estimate is certainly an additional burden to compilers, which might cause a lack of precision in statistics. Users are the reason why we are: User satisfaction is also one of the elements in evaluating the qu ality of statistics.

9. Increasing importance of more up to date macroeconomic statistics (especially in inflation- targeting monetary policy regime) One-step ahead policy considerations Reducing the time lag between turning point in the business cycle and policy measures Making strong meat counter-cyclical policy near reference date digestible Improvement in the effectiveness of preemptive economic policy measures and confidence in them

10. Less model Less judgement More source data Statistical infrastructure and capacity still be primary priority Development of monthly GDP
