More Stimulus Needed?

I’ve defended the stimulus and criticized some of its design; well I still feel similarly, but as Matthew Yglesias points out (via Mark Thoma) fiscal stimulus on net hasn’t happened. Read his whole short post – but here’s the relevant quote from Thoma:

But it’s important to remember that the proper measure for fiscal stimulus is not spending by the federal government; it is spending by all levels of government. And when you look at the contributions to US GDP growth (Table 1.1.2 at the BEA site), total government spending has been a drag on growth over the past two quarters. The increases at the federal level have not been enough to compensate for the spending cuts at the local and state levels.

It is also important to realize that a $787 billion stimulus package over 3 years seems large, but compared to the size of the US economy as a whole (14.2 trillion in 2009) it is easy to see why it might not have been large enough. According to the IMF, “U.S.’s planned stimulus amounts to 2 percent of output in 2009 and 1.8 percent” in 2010.  Krugman most frequently made this point before the Recovery Act passed and argues it now to push for further stimulus.

Consider the long-run budget implications for the United States of spending $1 trillion on stimulus at a time when the economy is suffering from severe unemployment.

That sounds like a lot of money. But the US Treasury can currently issue long-term inflation-protected securities at an interest rate of 1.75%. So the long-term cost of servicing an extra trillion dollars of borrowing is $17.5 billion, or around 0.13 percent of GDP.

And bear in mind that additional stimulus would lead to at least a somewhat stronger economy, and hence higher revenues. Almost surely, the true budget cost of $1 trillion in stimulus would be less than one-tenth of one percent of GDP – not much cost to pay for generating jobs when they’re badly needed and avoiding disastrous cuts in government services.

Also, Bruce Bartlett links to a study which “found that fiscal contraction in the states offset almost 100% of the fiscal stimulus at the federal level in 2009.”

Federal fiscal expenditure stimulus has mostly compensated for the negative state and local stimulus associated with the collapsing tax revenue and the limited borrowing capacity of the states. While this is a significant accomplishment, the net effect is that the consolidated fiscal expenditure stimulus is small, at a time when the private sector’s deleveraging has reduced private consumption. Thus, the fiscal expenditure stimulus did not manage to provide a viable cushion for the negative stimulus associated with private sector’s declining demand.
