In a two-agent setting, one agent ("landlord") seeks to maximize his residual gain, i.e., that part of output remaining after payment of a reward to the other agent ("worker"). The reward must be a function of the worker's output since his effort cannot be directly observed, and the landlord...

It is shown that if an economy's participants cannot be separated into groups across which there are no potentially conflicting interests--i.e., if the economy is "indecomposable"--then every continuous truth-dominant allocation mechanism will attain nonoptimal allocations on an open dense set...

This paper obtains finite counterparts of previous results that showed the informational efficiency of the Walrasian mechanism among all mechanisms yielding Pareto-optimal individually rational trades in exchange economies while using a continuum of possible messages. In particular, we develop...
