Stimulus? Essentially no effect... ever.... except on the creation of more bureaucracy

Contrary to many standard assertions, it looks as if increased gubmnt deficits in the US have had (and would have had) any stimulus effect. It would be nice if standard Keynesian models could be dropped from intro texts and from political speeches. [h/t Gabriel]. Here's the abstract from this paper: 

This paper asks whether increases in government spending stimulate 

private activity. The first part of the paper studies private spending. 

Using a variety of identification methods and samples, I find that in 

most cases private spending falls significantly in response to an 

increase in government spending. These results imply that the 

average GDP multiplier lies below unity. In order to determine

whether concurrent increases in tax rates dampen the spending 

multiplier, I use two different methods to adjust for tax effects. 

Neither method suggests significant effects of current tax rate 

changes on the spending multiplier. In the second part of the paper, 

I explore the effects of government spending on labor markets. 

I find that increases in government spending lower unemployment. 

Most specifications and samples imply, however, that virtually all 

of the effect is through an increase in government employment, 

not private employment. I thus conclude that on balance 

government spending does not appear to stimulate private activity.
