The final revision of Japan’s second-quarter [B]Gross Domestic Product[/B] report revealed the economy grew less than economists predicted, adding 0.6% versus the originally reported 0.9%. Output expanded 2.3% from the previous year, much less than the 3.7% expansion quoted in initial estimates. Government spending and net exports drove growth higher for the first time in 15 months, supported by both domestic and overseas fiscal stimulus as well as the inventory cycle, while private demand shrank to shave -1.3% off total output. The question now facing Japan as well as most other developed countries is what happens when restocking runs its course and the flow of government cash invariably dries up. At this point, the likely answer sounds far from encouraging: the jobless continues to rise, driving spending lower; the trend in current account figures points lower, suggesting little future support from the external sector; and deepening deflation threatens to engineer another “lost decade” in the world’s second-largest economy.
