So Why Is Obama Considering another "Stimulus"?!?

Bigger government hurts growth by diverting resources from productive uses to political purposes. That's common sense to most people. But it's nice to find even academics at Harvard are confirming this relationship - and showing that having local politicians with seniority is bad for growth since it means even more wasteful spending. Excerpted below is the abstract of a new study from the Harvard Business School, and kudos to Veronique de Rugy, who alerted me to this report by putting up a post at National Reveiew's Corner:

This paper employs a new empirical approach for identifying the impact of government spending on the private sector. Our key innovation is to use changes in congressional committee chairmanship as a source of exogenous variation in state-level federal expenditures. In doing so, we show that fiscal spending shocks appear to significantly dampen corporate sector investment and employment activity. These corporate reactions follow both Senate and House committee chair changes, are present among large and small firms and within large and small states, are partially reversed when the congressman resigns, and are most pronounced among geographically-concentrated firms. The effects are economically meaningful and the mechanism - entirely distinct from the more traditional interest rate and tax channels - suggests new considerations in assessing the impact of government spending on private sector economic activity.
