Noriel Roubini on the need for fiscal stimulus to prevent a financial meltdown

Given the collapse of private aggregate demand, consumption, residential investment and non-residential investment in structures are falling, and capital expenditure by the corporate sector was already falling before the latest financial shock and will now be plunging at an even faster rate. You need to give a boost to aggregate demand to ensure that an unavoidable two-year recession does not become a decadelong stagnation.

Since the private sector is not spending, and since the first fiscal stimulus plan (tax rebates for households and tax incentives to firms) failed miserably as households and firms are saving rather than spending and investing, it is necessary now to boost public consumption of goods and services via a massive spending program (a $300 billion fiscal stimulus).

The U.S. government should have a plan to immediately spend on infrastructure and new green technologies; also unemployment benefits should be sharply increased, together with targeted tax rebates only for lower income households at risk; and federal block grants should be given to state and local government to boost their infrastructure spending (roads, sewer systems, etc.). If the private sector does not or cannot spend, old-fashioned, traditional Keynesian spending by the government is necessary. It is true that the U.S. already has large and growing budget deficits; but $300 billion of public works is more effective and productive than spending $700 billion to buy toxic assets.

… Radical action can – and should – be taken to control the damage and prevent this meltdown from occurring.
