Do lobbyists provide issue-specific information to members of Congress? Or do they provide special interests access to politicians? We present evidence to assess the role of issue expertise versus connections in the US Federal lobbying process and illustrate how both are at work. In support of the connections view, we show that lobbyists follow politicians they were initially connected to when those politicians switch to new committee assignments. In support of the expertise view, we show that there is a group of experts that even politicians of opposite political affiliation listen to. However, we find a more consistent monetary premium for connections than expertise.

We explore the role of charitable giving as a means of political influence. For philanthropic foundations associated with large US corporations, we present three different identification strategies that consistently point to the use of corporate social responsibility in ways that parallel the strategic use of political action committee (PAC) spending. Our estimates imply that 6.3 percent of corporate charitable giving may be politically motivated, an amount 2.5 times larger than annual PAC contributions and 35 percent of federal lobbying. Absent of disclosure requirements, charitable giving may be a form of corporate political influence undetected by voters and subsidized by taxpayers.
