The Interest Group Top Tier: More Groups, Concentrated Clout

From the abstract:
Recent research on influence has produced seemingly contradictory findings. On the one hand, some scholars have shown that on any given issue, economic resources show little relationship to the likelihood of policy success (Baumgartner et al. 2009). Yet, other scholars have found that policy outcomes match the preferences of the top interest groups and the well-off much better than the average citizen (Gilens 2012). This paper offers an empirical resolution to this puzzle by closely examining the advocacy activities of the top tier of interest groups in Washington. As the total population of interest organizations has increased beyond the capacity of the government to pay attention to all of them, the select few at the top — mostly business interests — have concentrated their resources toward maintaining their privileged status as major players. Using a new data set of 37,706 unique interest groups who reported lobbying between 1998 and 2012, we show that the organizations at the top in lobbying expenditures, number of lobbyists, and number of firms and staff, increasingly retain their privileged positions — but need to pay more to do so. We document lobbying activity trends for those organizations at the top of the extremely unequally distributed lobbying population. We find that organizations at the top in one year pay more to stay at the topeach successive year, even if that means shifting their issue agenda to whatever is on the minds of Congress.
