Here is more on Senator Obama's tax plans.The small rise in spending in response to these tax rebates is similar to what previous studies of one-time tax cuts found. It also corresponds to what both basic economic theory and common experience imply. Although someone who receives a permanent annual salary increase of $1,000 typically would increase his annual spending by an almost equally large amount, a $1,000 rise in wealth caused by a share price increase or a tax rebate would raise spending only gradually over a number of years.
All of the evidence on one-time tax rebates implies that the Obama plan to send $1,000 rebate checks would do little to raise consumer spending and stop the decline in employment. If the past is an indicator of what would happen, the $65 billion he proposes to spend on this plan would raise consumer spending by only about $10 billion, or less than one-tenth of 1% of GDP.
The distinction between one-time tax rebates and permanent changes in net income is also important for the debate about Mr. Obama's proposal to raise income and payroll taxes. Because those tax increases would be permanent, they would cause a substantial reduction in consumer spending and aggregate demand. Moreover, as taxpayers begin to focus on the possibility of such a future tax hike, they will reduce spending without waiting for such legislation to be enacted. If Mr. Obama is looking for a way to stimulate the economy, he could begin by discarding his proposal to increase future taxes.
