ABSTRACT
From its establishment in the 1980s the International Evaluation Research Group has sought specifically to study and advance the cause of policy evaluation from an international comparative perspective. The increase in nongovernmental provision of public services raises issues of socioeconomic policy and politics including the Share of tax revenues consumed by these enterprises as proxy agents for governments. Legal rationality is that of acting consistently with rules that specify responsibilities of commission and omission, of due process, and regularity. Social rationality is that of social cohesion and integration. Political rationality takes social rationality into the political system: an action is politically rational if it furthers the integration of the decision-making system, but irrational if it degrades it. Economic rationality selects and evaluates both ends and means explicitly by reference to their utilities in circumstances of scarcity. Thus it is the reasoning of economizing and adding net value.
