The institute's first study, released in March 2006, argued for the elimination of the earnings tax in St. Louis and Kansas City. In October 2006, the institute released two studies examining the impact of a proposal on the November ballot to increase the minimum wage. In February 2007, the institute released a widely-discussed report on mayoral control of the St. Louis public school system. In October 2007, the Institute held a conference with leading education policy and legal scholars on the impact of the Missouri Supreme Court's recent school finance decision. While the institute was not involved in the case, three of the organization's board members intervened on behalf of taxpayers in the case and helped defeat a judicially-mandated increase in education funding. In January 2008, the institute released a study on the fiscal impact of a proposed school choice proposal and another study criticizing a Kansas City light rail proposal.
