When I first read about this, I believed that Stiglitz really disagreed with me. Let's take a peek on the FT:

"Do not squander America’s stimulus on tax cuts

By Joseph Stiglitz

As news of the US economy worsens, worries about whether a stimulus could restart the economy are growing. Making matters more complicated is the fact that our 2009 fiscal deficit will exceed 8 per cent of gross domestic product( TRUE, WHICH IS ONE MORE REASON THE BUSH YEARS HAVE BEEN A NIGHTMARE ), even before the stimulus.

What is clear is that tax cuts will not help much. When Barack Obama, president-elect, last week proposed to use nearly 40 per cent of the stimulus for tax cuts, he was rightly told this would be less effective than, say, spending on infrastructure( HERE, I DON'T AGREE ). It has been surprising, then, to see President George W. Bush’s former economic advisers, including Greg Mankiw, argue that tax cuts are the way forward.

Mr Mankiw cites a recent study by Christina Romer and David Romer, economists at the University of California, Berkeley, who found that each dollar of tax cuts raises GDP by about $3 (€2.30). Such studies, based on past data, may have little to say about the situation the world now faces( CHUCK THEM ). Americans confronted with debt, shrinking retirement accounts, houses worth less than mortgages and a tough credit environment will save more of their money than in the past( TRUE. FOR A WHILE. ). That was the experience with the February 2008 tax cut, where less than half of it has been spent. It matters who gets the break – if it is lower income Americans, the fraction spent will, on average, be greater( TRUE ) than for wealthier Americans.

Tax breaks for business may prove to be a sink-hole as bad as the troubled assets relief programme. Particularly worrisome are rumours that companies will be allowed to set off their losses against profits made in the past five years to get tax rebates( I AGREE ) – a big gift to those who mismanaged risk, including banks such as Citibank. Some suggest that, having exhausted the more transparent bail-out strategy, banks are seeking less transparent help through the tax code. We learnt the lesson from Tarp: we need to link handouts to changes in behaviour( I AGREE ). We should have insisted banks commit to more lending. Now we should insist any tax breaks for business are linked to investment( HE AND I AGREE ).

Similar caution needs to be exercised in evaluating each element of the stimulus package. The Obama team has issued a report projecting its potential for job creation. In estimating the impact of offering relief to the states, it assumed, based on experience, that 30 per cent of the relief would be used to stall tax increases that would otherwise have occurred. (States are facing a shortfall of perhaps $150bn a year.) But with property values plummeting, there is pressure to cut property taxes. And, in any case, state taxes are more regressive than federal taxes – more of the burden of taxation is borne by those with lower incomes. This means that if tax cuts come partly at the expense of state relief, and states are forced to raise taxes, the net effect on the economy is likely to be negative.

There is a more fundamental point that the Bush team missed. Tax cuts have increased our national debt. They encouraged( ONLY THAT ) America to live beyond its means, increasing our liabilities without commensurate increases in assets( WEREN'T HOUSES ASSETS ). Further tax cuts would do the same. Good accounting looks at assets and liabilities. Spending on infrastructure, education and technology create assets; they increase future productivity( IF THEY ARE WELL SPENT. OTHERWISE, THEY CAN DO GREAT HARM. IT'S NOT A PRIORI A GREAT INVESTMENT. ).

Some of the spending in the stimulus serves multiple ends. Increased unemployment benefits ( NOT A STIMULUS )have the largest multiplier effects – cash-strapped families spend every cent given – and meet vital social needs. It is imperative to provide health insurance to the unemployed( NOT A STIMULUS ): without that, a single serious incident can push a family into bankruptcy. Helping the unemployed meet house payments reduces foreclosures, addressing one of the underlying causes of the crisis. There are thus triple benefits.( BUT NOT A STIMULUS. THIS IS SOCIAL SAFETY NET SPENDING. )

We are in uncharted territory in this crisis. But household tax cuts, except for possibly the poorest, should have no place in the stimulus. Nor should business tax breaks, except when closely linked with additional investment( I AGREE ). The one tax cut that should be included is a temporary incremental investment tax credit; it provides a big bang for the buck, encouraging companies to invest now when the economy needs the spending( I AGREE ). Increased investments in infrastructure, education and technology, relief to states, and help to the unemployed need pride of place.

This is a stimulus that some Republicans will find less attractive than previous give-aways. But Americans voted for change they could believe in. I trust that that is what we will get.

My only disagreement is about one tax cut, but it's big. I would like a sales tax cut or payroll tax cut which will be phased out in the future, giving people an incentive to spend now instead of waiting. Some people will save money by not spending, but that's fine as well.
