DEFICIT ISSUES

 
 
The federal government's promise to extricate the U.S. economy from this recession involves more spending (increasing public debt) and more subsidies for consumers, such as car rebates and home buying incentives (more private debt). In other words, more debt is supposed to solve the problem of over-indebtedness. The truth is that this policy merely indentures its citizens further without providing any income for repayment of debt. In previous letters we have discussed the fact that the government spending multiplier is zero (read Professor Robert Barro's book, Macroeconomics - a Modern Approach, p. 370).
This means there is no long term income benefit from stimulus programs. According to the latest academic research, the most recent $800 billion stimulus plan will boost economic activity in the short run, but will surely depress economic activity over time. The government problem is complicated by the fact that the tax multiplier is 3, meaning that a 1% change in taxes will change GDP by about 3% over time. More recent research (Barro & Redlick, September 2009,"NBER Working Paper 15369"suggests that a 1% cut in the marginal tax rate would raise GDP in the ensuing year by 0.6%. With the deficit rising due to a zero spending multiplier, the tendency will be to try to raise taxes to pay for this higher level of expenditures, which will further depress aggregate spending and output.
