چکیده

Suppose a principal cannot commit to a centralized grand-mechanism with all his privately informed agents but can only sign public bilateral contracts with each of them. The principal can manipulate what he learns by contracting with an agent when dealing with others. Introducing this possibility for manipulations may simplify significantly optimal mechanisms. It restores both the continuity of the principal’s and the agents’ payoffs and that of the optimal mechanism with respect to the information structure. Still, correlation remains useful to better extract the agents’ information rent. In private values contexts, a Revelation Principle with bilateral contracting identifies the set of implementable allocations by means of simple non-manipulability constraints. Equipped with this tool, we characterize optimal non-manipulable mechanisms in various environments.

Contracting Out Non-State Providers to Provide Primary Healthcare Services in Tanzania: Perceptions of Stakeholders

Background In the attempt to move towards universal health coverage (UHC), many low- and middle-income countries (LMICs) are actively seeking to contract-out non-state providers (NSPs) to deliver health services to a specified population. Research on contracting-out has focused more on the impact of contracting-out than on the actual processes underlying the intervention and contextual factors ...

Dominant Strategy Implementation of Bayesian incentive Compatible Allocation Rules*

A large literature on incentive mechanisms represents incentive constraints by the requirement that truthful reporting be a Bayesian equilibrium. This paper identifies mechanism design problems for which there is no loss in replacing Bayesian incentive compatibility by the stronger requirement of dominant strategies. We identify contexts where it is possible to change the transfer payments of a...

The timing of contracting with externalities

This paper endogenizes the timing of bilateral contracting between one principal and multiple agents in the presence of externalities. Contracting simultaneously with all agents is optimal for the principal if externalities become weaker the more an agent trades. If instead externalities become stronger, sequential negotiations might benefit the principal as they lower the agents’ outside optio...

Support for B2B E-Contracting - The Process Perspective

In business-to-business relations, contracts serve both as a protection mechanism of trading partners, as well as a prescription document for activities to be executed by the parties. The processes of contract establishment and its enactment are often expensive and time consuming. E-contracting aims at automation of these processes, making them faster and cheaper. For the design of an informati...
