To test the ways in which politicians influence public opinion, the authors conduct two studies. The structures of the two studies are nearly identical.

An experimental design was used in which the NSP program was partially extended to ten non-NSP districts in 2007; in each of these, 50 villages were selected and then randomly assigned to take part in NSP or not.
