What happens when a state is lucky enough to have one of their Senators ascend to one of the three most powerful committee chairmanships? According to a new study by three Harvard Business School the average state then experiences a 40 to 50 percent increase in earmark spending (the figure is a smaller 20% for powerful House committees). So this new government spending is then a boon to the state right? The public spending stimulates economic growth right? Wrong. Turns out, increased federal spending is connected with a decrease in corporate capital expenditures and employment.
