The past week brought news of US double-digit unemployment and the Federal Reserve's decision to maintain near-zero interest rates. Both pieces of news expose the inadequacy of US economic policymaking. The Obama administration's stimulus policies are not well-targeted. The Republican alternatives are even worse. Both sides are missing the key fact: the US economy needs structural change that requires a new set of economic tools.

Consumer and investment demands are too low for full employment. Consumer sectors such as housing no longer generate adequate spending by households and businesses.

Potential investors exploring more promising areas, such as low-carbon energy and infrastructure, are stymied because of the lack of a clear policy framework. Neither the Keynesian approach favoured by the Obama administration, nor the tax-cuts favoured by Republicans, addresses the problem at this structural source.
