es in the public sector and their implications: multiplicity of goals,
unclear weighing of these goals, and nonmeasurability of some of them
: lack of comparison, heterogeneity of tastes and dispersion of princi
pals. The paper then analyzes career concerns, associated with the pro
spect of re-election. promotion, or employment in the private sector,
and articulated around some mission. There is a potential multiplicity
of missions that can be followed by rational officials. The last part
studies the division of labor within government, in particular divisi
on of labor among ministries and the use of multiple principals to con
trol economic agents, and division of labor aimed at creating informat
ion for public decision making and the use of enfranchised advocates o
f specific interests.
