The world economy is entering a new phase after the failure of fiscal stimulus to create a sustained recovery in either the US or Europe. In the US, consumers have retrenched, housing starts have crashed and a double-dip recession is possible. In Europe, fiscal retrenchment is under way after intense market pressures. A new approach to recovery is needed.
The striking feature in the current debate about austerity and stimulus has been the lack of attention to investment. Consumers will not provide the engine of recovery, nor should they after overspending for a decade. Instead, the US and Europe should be using the recent corrective boost in saving rates to promote long-term investments in physical and human capital as the proper way back to sustained growth.
In spite of the evident need for a rise in national saving after 2008, President Barack Obama tried to prolong the consumption binge by aggressively promoting home and car sales to already exhausted consumers, and by cutting taxes despite an unsustainable budget deficit. The approach has been hyper short term, driven by America's two-year election cycle. It has stalled because US consumers are taking a longer-term view than the politicians.
