Mechanism Design without Money

Despite impossibility results on general domains, there are some classes of situations in which there exist interesting dominant-strategy mechanisms. While some of these situations (and the resulting mechanisms) involve the transfer of money, we examine some that do not. Specifically, we analyze: problems where agents have single-peaked preferences over a 1-dimensional "public" policy space; problems where agents can trade/consume a single, indivisible "private" good; and problems where agents must match with each other.
