Scientific basis of modern weather prediction.

meeting of the "Group of Six" (10) on 22 February 1987 seemed to generalize that agreement to cover all the participants, although it failed to include the firm commitments to complementary changes in fiscal policy (covering both tax cuts in Germany and Japan and tax increases in the United States) that would have been called for by the guidelines laid out in this paper. In other words, there is still a long way to go from the ad hoc agreements that are back in fashion to the sort of articulated, comprehensive arrangements embodying agreed principles of policy adjustment when variables deviate from published target values that would constitute a new exchange-rate regime. The U.S.-Japan agreement will be significant if, but only if, it can in retrospect be seen as a milestone on the road to a comprehensive reform of the intemational monetary system.
