Reuters - World Bank urges keeping fiscal stimulus till 2012.

Countries should not rush to end fiscal incentives to help their economies cope with the global economic crisis, in order to build a base for sustained long-term growth, the World Bank's chief economist said.

Justin Lin said on Sunday he expected full global economic recovery in 2013. He said countries should keep fiscal measures in place until 2012, despite concerns from policy makers about the risk of inflationary pressure from higher government borrowing to fund the plans

That seems right to me. As is Lin's follow on comment:

In high income countries they can use the money to invest in a green economy to stop the problem of global warming. To reduce the CO2 emissions

Looks like he's bought into the Green New Deal.
