Japan’s Big-Works Stimulus Is Lesson - NYTimes.com

In a nutshell, Japan’s experience suggests that infrastructure spending, while a blunt instrument, can help revive a developed economy, say many economists and one very important American official: Treasury Secretary Timothy F. Geithner, who was a young financial attaché in Japan during the collapse and subsequent doldrums. One lesson Mr. Geithner has said he took away from that experience is that spending must come in quick, massive doses, and be continued until recovery takes firm root.

Moreover, it matters what gets built: Japan spent too much on increasingly wasteful roads and bridges, and not enough in areas like education and social services, which studies show deliver more bang for the buck than infrastructure spending.
