We explore the notion of "verifiability" by analyzing a simple model of evidence production in contractual relationships with complete information. We characterize implementability in terms of the existence and form of "hard evidence." We provide results on maximal and minimal evidence...

We explore the conceptual basis of "verifiability" by explicitly modeling the process of evidence production in contractual relationships of complete information. Evidence is represented by documents, on the submission of which an enforcement authority conditions transfers between the...

In this short paper, we show how hard evidence can be incorporated into the mechanism-design framework. We model the parties' inalienable decisions (evidence production) as distinct from an arbitrarily-designed message form. A mechanism specifies the message form and how the public decision is a...
