This article uses a cross-national data set on the performance of gove
rnment investment projects financed by the World Bank to examine the l
ink between government efficacy and governance. It demonstrates a stro
ng empirical link between civil liberties and the performance of gover
nment projects. Even after controlling for other determinants of perfo
rmance, countries with the strongest civil liberties have projects wit
h an economic rate of return 8-22 percentage points higher than countr
ies with the weakest civil liberties. The strong effect of civil liber
ties holds true even when controlling for the level of democracy. The
interrelationship among civil liberties, civil strife, and project per
formance suggests that the possible mechanism of causation is from mor
e civil liberties to increased citizen voice to better projects. This
result adds to the evidence for the view that increasing citizen voice
and public accountability-through both participation and better gover
nance-can lead to greater efficacy in government action.
