In the market game presented here, sellers offer trade mechanisms to buyers, and buyers randomize over the sellers they visit. The distribution of buyers across sellers is endogenous and depends on all of the transaction opportunities existing in the market. Sellers choose from a broad class of...

This paper reports on the design of a novel two-stage mechanism, based on strictly proper scoring rules, that allows a centre to acquire a costly probabilistic estimate of some unknown parameter, by eliciting and fusing estimates from multiple suppliers. Each of these suppliers is capable of...

In this paper we summarize the theoretical arguments of Carson and Groves, et al., and assemble early empirical evidence that comports with this theoretical framework. In doing so, we argue that redefining criterion validity in terms of consequentiality offers the potential for a fundamental...

A budget-constrained buyer wants to purchase items from a short-listed set. Items are differentiated by observable quality and sellers have private reserve prices for their items. The buyer’s problem is to select a subset of maximal quality. Money does not enter the buyer’s...

We consider the design of an optimal voting system when voting is costly. For a private values model with two alternatives we show the optimality of a voting system that combines three elements: (i) there is an arbitrarily chosen default decision and non-participation is interpreted as a vote in...

This paper describes and analyzes the Greek Capacity Market or, as named, the “Capacity Adequacy Mechanism”. A detailed description of the recently established mechanism is given, whose design is a hybrid model combining elements from three different designs: the US Capacity Markets, the...

Bayesian implementation concerns decision making problems when agents have incomplete information. This paper proposes that the traditional sufficient conditions for Bayesian implementation shall be amended by virtue of a quantum Bayesian mechanism. Furthermore, by using an algorithmic Bayesian...

[Moore and Repullo, \emph{Econometrica} \textbf{58} (1990) 1083-1099] and [Dutta and Sen, \emph{Rev. Econom. Stud.} \textbf{58} (1991) 121-128] are two fundamental papers on two-agent Nash implementation. Both of them are based on Maskin's classic paper [Maskin, \emph{Rev. Econom. Stud.}...

This paper concerns what will happen if quantum mechanics is concerned in subgame perfect implementation. The main result is: When additional conditions are satisfied, the traditional characterization on subgame perfect implementation shall be amended by virtue of a quantum stage mechanism....
