Efficiency of an Information System in an Agency Model

Abstract: Different information systems are compared in terms of their relative efficiencies in an agency model. The mean preserving spread relation between the likelihood ratio distributions derived from the original information systems is found to be sufficient to rank information systems under quite general assumptions about the agent's utility function. Furthermore, it is shown that the mean preserving spread criterion can be applied to a broader set of information systems than Holmstrom's informativeness criterion and Blackwell's theorem.
