We study a credence goods problem - that is, a moral hazard problem with non-contractible outcome - where altruistic experts (the agents) care both about their income and the utility of consumers (the principals). Experts' preferences over income and their consumers' utility are convex, such...

Philanthropy, and particularly ensuring that one's giving is effective, can require substantial time and effort. One way to reduce these costs, and thus encourage greater giving, could be to encourage delegation of giving decisions to better-informed others. At the same time, because it involves...

We experimentally test the efficacy of indenture as a self-enforced contract device. In an indenture game, the principal signals the intention of payment-on-delivery, by tearing a banknote and giving the agent half of it as "prepayment"; the agent receives the completing half after delivering...

We analyze the costs and benefits of using social image to foster virtuous behavior. A Principal seeks to motivate reputation-conscious agents to supply a public good. Each agent chooses how much to contribute based on his own mix of public-spiritedness, private signal about the value of the...

This was the first article explicitly on the theory of agency published in a regular, i.e., nonproceedings, issue of a journal in social science.The paper presents a fiduciary function model of policing in agency, with an application to attempts to influence regulatory performance by policing...

The fiduciary norm, which prescribes agent behavior solely for the goal of the principal, without regard for other goals, is defined in the context of the theory of agency. The fiduciary program, a set of procedures for determining the principal's preferences and acting for them, is then defined...

We analyze the costs and benefits of using social image to foster virtuous behavior. A Principal seeks to motivate reputation-conscious agents to supply a public good. Each agent chooses how much to contribute based on his own mix of public-spiritedness, private signal about the value of the...

We examine optimal incentives for charitable giving with a large-scale field experiment involving 26 charities and over 112,000 unique individuals. The price of giving is varied by offering a fixed match if the donation meets a threshold amount (e.g. "give at least $25 and the charity receives a...

Principal-agent relationships are typically motivated by efficiency gains from comparative advantage. However, such delegation may also arise because it allows principals the pursuit of selfish outcomes while avoiding explicitly selfish behavior. We report laboratory experiments in which...
