 The second strand of political economy, constitutional political economy, does have normative aims. It assumes that political actors will act in a self-interested fashion within existing political institutions but that agents will act more impartially in the design of the political institutions within which they will  work.[24]  A normative theory of adjudication does emerge from this strand of political economy, but it differs significantly from the normative theory endorsed by the policy analysis strand of economic analysis of law. For constitutional political economy, a normative theory of adjudication must be a structural one; it should describe the structure of adjudication. The theory thus cannot dictate directly judicial motivation because, according to political economy, judges will always act self-interestedly. Adjudicative institutions, however, can be designed to align better the interests of judges with the interests of the designer of the constitution.
