# Myerson Satterthwaite With Platform Trading

The Myerson–Satterthwaite theorem is among the most remarkable and universally applicable negative results in economics—a kind of negative mirror to the fundamental theorems of welfare economics. It is, however, much less famous than those results or Arrow's earlier result on the impossibility of satisfactory electoral systems. · JOURNAL OF ECONOMIC THE () Efficient Mechanisms for Bilateral Trading ROGER B.

MYERSON AND MARK A. SATTERTHWAITE J. L. Kellogg Graduate School of Management, Northwestern University, Evanston, Illinois Received June 8, ; revised December 7, We consider bargaining problems between one buyer and one seller for a Cited by: Myerson and Satterthwaite considered an asymmetric initial situation, in the sense that at the outset one party has % of the good and the other party has 0% of the good.

It has been shown that ex post efficiency can be attained if initially both parties own 50% of the good to be traded. 3.

MYERSON AND SATTERTHWAITE individuals, one of whom has a single indivisible object to sell to the other, attempt to agree on an exchange of the object for money. Chatterjee and Samuelson have studied this two-person trading problem. Roger Myerson and Mark Satterthwaite, "E ﬃcient Mechanisms for Bilateral Trading," Journal of Economic Theory, Vol 29, p. ().

The paper concerns the possible trade of a single, indivisible item between a buyer and a seller. A key aspect of the model is that each trader privately knows the value to him of trading. So Mark Satterthwaite, you've seen his name on several different theorems now, the Muller-Satterthwaite, Gibberd-Satterthwaite, and now the Myerson-Satterthwaite Theorem. And what this theorem refers to is trade And it's basically going to say that it's going to be difficult to get efficient trade out with volunteering participation.

Myerson and Satterthwaite, "E ﬃ cient Mechanisms for Bilateral Trading," JET In many bilateral bargaining situations with asymmetric information, ex post e ﬃ ciency is inconsistent with incen- tive compatibility and individual rationality. One can compute the highest expected surplus consistent with IC.

· Journal of Economic Literature Classification Numbers:~Myerson and Satterthwaite [8] consider the problem of designing a trading institution for a buyer and seller.' The problem is that the buyer's and seller's valuation of the good are private information.

The analysis of Vickrey () and Myerson and Satterthwaite () highlights diﬃculties associated with designing eﬃcient centralized two-sided markets and has focused economists and policy makers on setups with one-sided private information (Milgrom,Chapter ).

Chatterjee and Samuelson [2] showed with a bilateral example that one cannot expect ex post efficiency from the double auction. exact characterization of when efﬁcient trade is possible in the bilateral trading problem of Myerson and Satterthwaite (), under the assumption that agents know little beyond each other’s expected valuation of the good (which is the in- formation structure that. Apart from these well‐known platforms, markets for trading novel forms of services have also emerged.

Energy services such as charging services for electric vehicles, for example, provide a value‐oriented approach toward quality‐differentiated electricity consumption (Myerson & Satterthwaite, ).

remain true for trading a divisible good, or for trading multiple goods against each other. The tools we develop are useful beyond bilateral trade models. 3Like Myerson and Satterthwaite we look at ex post eﬃciency in the sense that we evaluate eﬃciency assuming that we know the agents’ types.

We generalize the analysis of Myerson and Satterthwaite (), and derive the optimal direct-revelation mechanism for each α. As expected, the optimal mechanism applies a reserve price which is decreasing in α.

Next, we present an indirect implementation based on ``sharing schemes". ficient, the Myerson and Satterthwaite result establishes that efficiency cannot be used as a criterion for choosing among trading mechanisms.

Hence, the literature introduced other criteria to facilitate this choice. Gresnik and Satterthwaite () prove the existence of a constrained efficient. Roger Bruce Myerson (born ) is an American economist and professor at the University of Chicago.

## The Myerson-Satterthwaite Theorem

He holds the title of the David L. Pearson Distinguished Service Professor of Global Conflict Studies at The Pearson Institute for the Study and Resolution of Global Conflicts in the Harris School of Public Policy, the Griffin Department of Economics, and the College. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We consider a simple bilateral trading game between a seller and a buyer who have private valuations for an indivisible good.

The seller makes a price offer which the buyer can either accept or reject. If the seller can observe the valuation of the buyer (if information is symmetric), then the trading outcome is. augment, in a way that is familiar in the hold-up literature, Myerson and Satterthwaite’s canonical description of bilateral trade by allowing players’ valuation of the traded item to result from their unobserved investments.

When mixed strategies are played this causes asymmetric information to emerge endogenously. The nature of the Myerson—Satterthwaite Theorem is a proof that under efficiency the informational rents collectively exceed the total gains from trade, so that any efficient mechanism requires.

The Main Results Our work is inspired by a recent line of research that studies the power of simple mechanisms in comparison to the performance of the optimal, but complex, mechanisms (see, e.g. Downloadable (with restrictions)! We study the bilateral trading problem under private information. We characterize the range of possible mechanisms which satisfy ex-post efficiency, incentive compatibility, individual rationality, and budget balance.

In particular, we show that the famous Myerson–Satterthwaite impossibility result no longer holds when contingent contracts are allowed. Approximating Gains-from-Trade in Bilateral Trading products and services are sold on platforms that involve users of diﬀerent roles, usually sellers and buyers.

Thus, the gains from trade are insufficient to induce honesty by both parties. We characterize the range of possible mechanisms which satisfy ex-post efficiency, incentive compatibility, individual rationality, and budget balance.

Journal of Economic Theory, – · Myerson and Satterthwaite () demonstrated that bilateral trade will involve some failed trades whenever the support of the buyer’s and seller’s private valuations overlap – that is, when there is a possibility that no gains from trade actually exist.

· Myerson and Satterthwaite give the definitive answer: even the best of all possible market designs must be inefficient: it must leave some potential gains from trade unrealized. If markets were perfectly efficient, whenever individual A values a good more than individual B it should be sold from B to A at a price that they find mutually agreeable.
