Equilibrium impotence

"Why did states dominate investments in economic development in early America? Between 1787 and 1860, the national government spent $54 million on promoting transportation infrastructure while the states spent $450 million. Using models of legislative choice, we show that Congress could not finance projects that provided benefits to a minority of districts while spreading the taxes over all.
