We show that incentive efficient allocations in economies with adverse selection and moral hazard can be determined as optimal solutions to a linear programming problem and we use duality theory to obtain a complete characterization of the optima. Our dual analysis identifies welfare effects...

This economic experiment tests the positive relationship between perceived intention and positive reciprocity by altering material-payoff structures in treatments, or material-payoff approach. To design the treatments, this study applies a signalling model to explain how the intention of an...

We provide experimental evidence on the ability to detect deceit in a buyer-seller game with asymmetric information. Sellers have private information about the buyer’s valuation of a good and sometimes have incentives to mislead buyers. We examine if buyers can spot deception in face-to-face...

They have to rely on the recommendations of advisors. Incentives of advisors and clients may not be aligned, when...
