Optimal contracts between a buyer and a seller who trade multiple goods under asymmetric information are considered. The seller makes sequences of unobservable investments, and then realizes the value of the goods. The investment level and value of goods are private information for the seller...

When firms want to raise external financing, why do they resort to contracts with fixed repayment, i.e., standard debt contracts? The canonical work of Gale and Hellwig (Rev Econ Stud, 52(4):647–663, 1985) gives the following answer to this question: Assuming that only the entrepreneur can...

We study optimal smart contract design for monitoring an exchange of an item performed offline. There are two parties, a seller and a buyer. Exchange happens off-chain, but the status update takes place on-chain. The exchange can be verified but with a cost. To guarantee self-enforcement of the...

Strausz (2017) claims that crowdfunding implements the optimal mechanism design outcome in an environment with entrepreneurial moral hazard and private cost information. Unfortunately, his analysis, solution and claim depend critically on imposing an untenable condition (29) that he had...

The 2016 Nobel Memorial Prize in Economic Sciences was awarded to Oliver Hart and Bengt Holmström for their work on contract theory. Contract theory is a subfield of game theory where the conflict between the owner - the principal - and the CEO - or agent - is at the centre of interest. In the...

This paper provides a complete characterization of equilibria in a game-theoretic version of Rothschild and Stiglitz's (1976) model of competitive insurance. I allow for stochastic contract offers by insurance firms and show that a unique symmetric equilibrium always exists. Exact conditions...

A bilateral trading model with investment is considered. In a "cooperative" investment version of the model, the seller's investment stochastically determines the buyer's valuation of the good. The value and cost of the good are realized only after the investment is made, and the investment...

We modelize and investigate the analytical rationale of employing bilateral mechanism design, which simplifies collective mechanism design by ignoring relative information evaluation, in generalized multi-agency contracting games under Bayesian Nash equilibrium. We permit interdependent...
