Zhao Li: How Internal Constraints Shape Interest Group Activities

Interest groups contribute much less to campaigns than legally allowed. Consequently, prevailing theories infer these contributions must yield minimal returns. I argue constraints on PAC fundraising may also explain why interest groups give little.
Gleason Judd: Access and Lobbying in Legislatures

Human pro-sociality towards non-kin is ubiquitous and almost unique in the animal kingdom. It remains poorly understood, though a proliferation of theories has arisen to explain it. We present evidence from survey data and from laboratory treatment of experimental subjects that is consistent with a set of theories based on group level selection...
