Implementation of the Thompson mechanism

This paper reconsiders the largely overlooked Thompson insurance mechanism for public choice. The mechanism's apparent defects can be remedied by a multi-part mechanism that generates necessary information and corrects potential errors. The added parts are (a) a sample of the population of eligible voters, who prepare a program for all voters' approval, and (b) the Vickrey-Clarke-Groves pivot mechanism. One can use classical statistical methods to draw valid inferences from a population sample about the entire electorate, preserving incentive compatibility and permitting efficient outcomes.
