We consider two mechanisms to procure differentiated goods: a request for quote and an English auction with bidding credits. In the request for quote, each seller submits a price and the inherent quality of his good. Then the buyer selects the seller who offers the greatest difference in quality...

Self regulation is a mechanism of quality vigilance that is frequently used in credence good industries. The providers in these markets generally form a Self Regulated Organization (SRO), composed by some members of the industry, whose main job is to convince consumers through an active...

We provide necessary and sufficient conditions for observed outcomes in extensive game forms, in which preferences are unobserved, to be rationalized first, partially, as a Nash equilibrium and then, fully, as the unique subgame-perfect equilibrium. Thus, one could use these conditions to find...

A new approach for Robust DEA technical efficiency measurements is presented, based on a combination of Jackknife and Bootstrap resampling schemes. First, an algorithm implementing jackknife is used to extract leverage for all data points, that is, the impact of the removal of the observed point...

In this paper, the link between community enforcement and co-operation in environments where trust is required is investigated. For this purpose, an assymetric trust game in which peer-to-peer sanctioning mechanisms are available is considered. Firstly, the outcome of this game is characterised...

The use of dynamic auctions is a major component in many enterprises' e-procurement initiatives. In the case where suppliers offer goods and services of inherently different quality the traditional mechanism has been the request for quote. In a request for quote, suppliers submit a sealed bid...

Many commodities are such that the utility they create for individual consumers depends positively on the number of people also consuming these goods. Prominent examples among others are mobile phones, game consoles, and computer software. The customers form a network, where the size of the...

In this paper we analyse contributions to a public good within an inter-generational framework where at the end of each session one generation of subjects leave advice for the succeeding generation via free form messages. Such advice can be private (advice left by one player in generation t is...

We conduct an experiment to explore the durability and transferability of the increase in contributions to a public good resulting from the existence of a particular type of implicit informal sanction. Rege and Telle (2003) find that in one-shot games, the sanctioning system leads to high...

Ascending price clock auctions with drop-out information typically yield outcomes closer to equilibrium predictions than do comparable sealed-bid auctions. However clock auctions require congregating all bidders for a fixed time interval, which has limited field applicability and introduces...
