Walking the contractual tightrope: a transaction cost economics perspective on social impact bonds

ABSTRACT

Transaction cost economics is applied in this paper to social impact bonds to explore how public service commissioners could improve outcomes-based contracts. The authors supply a framework for assessing the quality of outcomes specifications and clarify the trade-off between a robust value case for government and the transaction costs associated with specifying such a deal. Illustrated by two examples, the authors suggest that commissioners aim for a ‘requisite’ contract: one that minimizes opportunism while balancing the costs of developing a more robust outcomes specification.
