Lessig takes on the model of lobbying as “legislative subsidy” developed by political scientist Richard Hall and economist Alan Deardorff as an alternative to the naive lobbying-as-bribe model. Legislators come to Washington passionate about several issues. Quickly, though, they come to depend on the economy of influence for help in advancing an agenda. They need the policy expertise, connections, public-relations machine, and all the rest that lobbyists can offer. Since this legislative subsidy is not uniformly available, the people’s representatives find themselves devoting more of their time to those aspects of their agenda that moneyed interests also support. No one is bribed, but the political process is corrupted.
That is from Matt Yglesias.
