When interactions across multiple markets are considered simultaneousl
y, some evidence suggests pollution control costs contributed to reduc
ing long-term productivity growth. This study examines the effect of e
nvironmental compliance costs, constituency influences, and incumbent
attributes on corporate PAC contributions from those manufacturing ind
ustries which have substantial costs and consequently have a rational
self-interest in providing differential rents to Senate incumbents to
implicitly influence regulatory policy. The authors find that corporat
ions have relatively precise targeting strategies for offering financi
al support to incumbent senators. However, these strategies are noneth
eless distinct from those strategies pursued by this set of corporate
PACs in giving to House incumbents.
