Constitutional Prohibitions in a Rent Seeking Model

I extend the standard rent seeking model to allow lobbying fora constitutional prohibition on wealth transfers. I examinetwo issues: (1) the ability of special interests withsignificant political capacity to block constitutional change;and (2) the effect of adding a constitutional stage on totallobbying expenditures. Defeating a prohibition on wealthtransfers is a public good for rent seekers; success inconstitutional politics merely allows them to lobby for wealthtransfers. The resulting collective action problem for rentseekers in constitutional politics offsets the generalinterest's free rider problems, reducing the probability oftransfers and expected total lobbying expenditures compared tothe traditional rent seeking contest. Introduction of aconstitutional stage also reverses several comparative staticsresults from the rent seeking game. An increase in the numberof rent seekers or the general interest's (consumers') abilityto organize increase lobbying in the rent seeking game butgenerally reduce expected lobbying in the constitutionalprohibition game.
