After the housing bubble burst, the Bush and Obama administrations turned to stimulus in an effort to "create jobs." Does such spending lead to economic improvement? Prof. Antony Davies examines the data to see how increases in federal spending relate to economic growth from 1955 to the present. The evidence shows that there is no connection between federal spending and economic improvement; instead, stimulus money only increases government debt. After three years of stimulus spending, the unemployment rate remains at 9 percent. "One thing that has changed," Davies says, "is that our government is now $4.6 trillion further in debt than it was before the stimulus efforts."
