Government contracts with private firms account for about 15% of the global economy. Routine publication of these contracts would yield immense benefits at nearly zero cost. Charles Kenny: “Imagine that three other people have built a bridge like this somewhere in the world in the last five years. One of those bridges has collapsed, one came in over cost, and one was absolutely wonderful. You go back to the contract and you can see if there’s a difference…between those three contracts and then you can learn to write a better contract.”
