Diversity for Access? Legislative Diversity, Identity Group Mobilization, and Lobbying

We examine the historical effects of ethnic and racial diversification among legislators on identity group mobilization and the hiring of nonwhite lobbyists. We propose that diversification among legislators encouraged identity groups to lobby, that these groups hired lobbyists who reflected their members' identities, and that all interests also hired lobbyists who reflected the identities of new legislative targets. We apply a Bayesian estimation approach to infer the identities of lobbyists who were active in the American states over several decades. We find that the election of African Americans to state legislatures encouraged black identity groups to lobby, that all identity groups, including those representing Hispanics or Latinos, generally hired lobbyists who reflected their members' identities, and that the election of Asian Americans to state legislatures encouraged interests generally to hire Asian-American lobbyists. Hispanic or Latino lobbyists gained clients in response to diversification in more Democratic legislatures.
