This paper reviews agency theory and its application to accounting issues. I discuss the formulation of models of incentive problems caused by moral hazard and adverse selection problems. I review theoretical research on the role of performance measures in compensation contracts, and I compare how information is aggregated for compensation purposes versus valuation purposes. I also review the literature on communication, including models where the revelation principle does not apply so that nontruthful reporting and earnings management can take place. The paper also discusses capital allocation within firms, including transfer pricing and cost allocation problems.

This paper uses an agency theory model in which the agent's actions are multi‐dimensional to analyze the optimal weights to apply to performance measures in a compensation contract. We show how the optimal contract trades off the congruity of the overall performance measure with the desire to minimize the risk imposed upon the agent. In contrast to the single action case, we find that an increase in the sensitivity of a performance measure to an agent's action does not necessarily increase the weight placed on that performance measure, even if that measure is perfectly congruent with the firm's outcome.
