This research contributes to the expanding literature on the determinants of government transparency. It uncovers the dynamics of transparency in the Italian case, which shows an interesting reform trajectory: until the late 1980s no transparency provisions existed; since then, provisions have dramatically increased under the impulse of changing patterns of political competition. The analysis of the Italian case highlights that electoral uncertainty for incumbents is a double-edged sword for institutional reform: on the one hand, it incentivizes the adoption of ever-growing transparency provisions; on the other, it jeopardizes the implementation capacity of public agencies by leading to severe administrative burdens.
