This article shows linkages between a broadened transaction-cost theor
y of politics and prior studies analyzing governmental behavior such a
s agenda control, strategic use of information, cost concealment and c
ost dispersion. It develops a model of government manipulation of poli
tically relevant transaction costs in order to facilitate both more co
mprehensive specification of the determinants of such political behavi
or and more accurate assessment of the likelihood and consequences of
institutional change. The article presents a taxonomy that classifies
conceptually various observed and potential forms of governmental tran
saction-cost manipulation.
