%0 Journal Article %T The Optimality of Team Contracts %A Mehmet Barlo %A Ay£¿a £¿zdo£¿an %J Games %D 2013 %I MDPI AG %R 10.3390/g4040670 %X This paper analyzes optimal contracts in a linear hidden-action model with normally distributed returns possessing two moments that are governed jointly by two agents who have negative exponential utilities. They can observe and verify each others¡¯ effort levels and draft enforceable side-contracts on effort levels and realized returns. Standard constraints, resulting in incentive contracts, fail to ensure implementability, and we examine centralized collusion-proof contracts and decentralized team contracts, as well. We prove that the principal may restrict attention to team contracts whenever returns from the project satisfy a mild monotonicity condition. %K principal-agent problems %K linear contracts %K collusion %K team %K decentralization %U http://www.mdpi.com/2073-4336/4/4/670
