This paper deals with the relative performance of private and public e
mployment services. For this purpose, two behavioral models are develo
ped which take into account that private and and public employment age
nts not only pursue different aims but also face different restriction
s, in particular since a public employment agency lacks the right to r
eject applicants. While analysis of the necessary optimality condition
s yields tentative conclusions about the advantages and disadvantages
of both types of employment service, empirically testable hypotheses r
esult from the predicted responses to increases in unemployment and in
the cost of service, respectively. These predicted behaviors are like
ly to be considered unfair by society, causing dissatisfaction with bo
th private and public employment agencies.
