Procurement Auctions for Differentiated Goods

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 and price. In the English auction with bidding credits, the buyer assigns a bidding credit to each seller conditional upon the quality of the seller’s good. Then the sellers compete in an English auction with the winner receiving the auction price and his bidding credit. Game theoretic models predict the request for quote is socially efficient but the English auction with bidding credits is not. The optimal bidding credit assignment under compensates for quality advantages, creating a market distortion in which the buyer captures surplus at the expense of the seller’s profit and social efficiency. In experiments, the request for quote is less efficient than the English auctions with bidding credits. Moreover, both the buyer and seller receive more surplus in the English auction with bidding credits.

The performance of reverse auctions versus request for quotes when procuring goods with quality differences

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 and the fixed quality of their offering and then the buyer selects the seller who offers the greatest difference between quality and price. The winning seller receives a price equal to his submitted bid. The reverse auction has immerged as the most commonly adopted dynamic auction for this setting. In a reverse auction, suppliers first submit the qualities of their goods and then the suppliers participate in an auction with the same message space as an open outcry English auction (descending because this is a procurement auction.) However, the auction is only used to set each suppliers price. The last price a supplier submits in the auction becomes their actual submitted price. After, the auction the buyer selects the winning seller who offers the greatest difference between quality and actual submitted price. We provide a game theoretic analysis of both mechanisms. We also provide extensive experimental evaluation of the two mechanisms as wellReverse Auction, Request for Quote, procurement

Russia: The Long Road to Ratification. Internal Institution and Pressure Groups in the Kyoto Protocol’s Adoption Process

The Russian Federation played a crucial role in the ratification of the Kyoto Protocol. Indeed, after the US decision not to comply with the treaty, its ratification turned out to be indispensable for the Protocol to become legally binding. In early 2002, the Russian government decided to initiate the ratification process. However, notwithstanding this initial commitment, the country long hesitated to fulfil its promises, and for the last two years it sent numerous contradictory signals with respect to its position on climate policy. As a consequence, the factors that shape Russia’s behaviour in the context of climate negotiations received increasing attention. The main focus has been on the economic and international aspects motivating the Russian strategy. This paper attempts to complete this analysis by concentrating on a further feature that significantly contributed to Russia’s final decision, namely domestic forces. These factors have often been overlooked in the discussion of the Russian strategy. In order to fill this gap, this paper reconstructs the Russian ratification process, trying to identify the main domestic players and their role. Our findings provide various indications on the reasons of the recent developments in Russia, confirming the key role of the Russian President.Agreements, Climate, Incentives, Negotiations, Policy

Anti-Racist Policies in France. From Ideological and Historical Schemes to Socio-Political Realities

In France, since the 1980s, imaginaries derived from decolonization have played a major role in the elaboration of anti-racist policies. Simultaneously, because of the universalistic conception of the French Republic, the use of ethnic categories has been taboo and systematically replaced, in political schemes, by socio-economic criteria. Multiculturalism, in the Anglo-Saxon meaning, has therefore not been a traditional political analysis framework. Nevertheless, since the 1990s, the French model of integration, which was based on the individual, has been more and more accused of giving way to inequalities and racism. For ten years, the rise of the concept of the «ethnicization» of cultural groups in public debate has thus inspired political demands that require concrete answers, notably against urban violence and education.Anti-racist policies, French model of integration, Multiculturalism, Ethnicization, Urban violence, Education

Rational Individual Behavior in Markets and Social Choice Processes

This paper reviews a series of paradoxes that exist in the experimental economics literature. These paradoxes are instances in which otherwise accurate models of markets and social choice processes fail to capture the data of experiments. A loosely developed theory called The Discovered Preference Hypothesis is advanced in the paper as an explanation. Behavior seems to go through stages of rationality that begin with a type of myopia when faced with unfamiliar tasks. With incentives and practice, which might take the form of repeated decisions in the experimental work, (but might include play, banter, discussions with others, stages of commitment, etc.) the myopia gives way to what appears to be a. stage of more considered choices that reflect stable attitudes or preferences (as opposed to the labile attitudes identified by psychologists). Social institutions are seen as playing a role in the attainment of a third stage of rationality in which individual decisions incorporate the rationality of others, or the lack of it, in their own decisions

Procurement Auctions for Differentiated Goods

 We consider two mechanisms to procure differentiated goods：a sealed-bid buyer-determined auction and a dynamic-bid price-based auction with bidding credits. The sealed-bid buyer-determined auction is analogous to the “request for quote” procedure commonly used by procurement agencies, and has each seller submit a price and the inherent quality of his good. Then the buyer selects the seller who offers the greatest difference in quality and price. In the dynamic-bid price-based auction with bidding credits, the buyer assigns a bidding credit to each seller conditional upon the quality of the seller’s good. Then the sellers compete in an English auction, with the winner receiving the auction price and his bidding credit. Game-theoretic models predict the sealed-bid buyer-determined auction is socially efficient but the dynamic-bid price-based auction with bidding credits is not. The optimal bidding credit assignment undercompensates for quality advantages, creating a market distortion in which the buyer captures surplus at the expense of the seller’s profit and social efficiency. In our experiment, the sealed-bid buyer-determined auction is less efficient than the dynamic-bid price-based auction with bidding credits. Moreover, both the buyer and seller receive more surplus in the dynamic-bid price-based auction with bidding credits.This paper has been published in Decision Analysis
