Article
The Office National des Forêts (ONF) in France uses sequential auctions to sell a significant portion of timber from public forests. This mechanism, based on a competitive dynamic between buyers, relies on randomization at two key moments: at the start of the sale, to determine the order in which timber lots are auctioned, and at the end, to break...

Le système d’enchères est, depuis des siècles, bien adapté aux spécificités du marché du bois. Mais il est aussi accusé d’être à l’origine du manque de compétitivité de l’appareil de transformation français, et de pertes de revenus pour les propriétaires des forêts publiques. Pour répondre à ces critiques, les contrats de gré à gré se sont multipli...

“Fair” Price and Professional Reputation: a Double Challenge for Public Timber Auctions In France, the fixing of prices of public timber lots, sold during auctions by the National Forests Office ( Onf ), is problematic due to the lots’ singularity. Based on an ethnographic study, this article shows that auctions lead the participants to come to a...

The Embedding and De-embedding Process of Public Timber Auctions This article analyses the dynamics of the embedment/(dis)embedment process at work in French public timber auctions. It presents the different conditions and forms of coordination created by local buyers to share lots and batches. However, we show that under the influence of economic...

The ONF’s sales catalogue The auction sales of public forests in France mainly concern standing or processed timber by lump sum. This particularity means that buyers often have to go and see the timber themselves in order to estimate the value of the lots that on the day of the sale are physically absent. This gives rise to high transaction costs a...

The Art to organize timber auctions. The auction sales of public timber are not just about agents’ rational calculations, who – beneath the sales director’s impassive / detached eyes – anonymously confront their bids and demands. The sale requires that participants take part in a sort of a show, which is influenced, among other things, by the actio...

De tout temps la forêt publique est apparue, en France, comme une ressource financière stratégique pour les autorités en charge de leur gestion, justifiant face au risque de collusion le recours au système d’enchères. L’article propose, à partir d’une enquête de terrain, d’étudier les pratiques coopératives mises en oeuvre par les acheteurs durant...

Article
Les ventes aux enchères de bois public ne se réduisent pas au calcul froid des agents walrasiens qui, sous le regard détaché du directeur de vente, confronteraient de façon anonyme leurs offres et leurs demandes. Elles impliquent la réalisation de la part des acteurs d’un jeu scénique influencé entre autre par les éléments de « décor ». Loin de la...
Article
La thèse porte sur la problématique de la mise en vente des bois publics. À partir d’une étude réalisée sur la région Lorraine, nous identifions tout d’abord les conditions d’encastrement de ces ventes, considérant que les comportements des participants sont déterminés par l’interaction complexe de facteurs économiques, socio-structuraux, politique...
Article

A ce titre, nous étudions, dans la première partie de la thèse, le système d’enchères qui reste encore le principal mode de vente utilisé par l’Office National des Forêts. Nous identifions le...

This article suggests to apply the evolution of the merchant institutions used to sell public timber, with reference to the theory of “Path Dependence”. First we present, in a socio-economic perspective, the features which led, since the 17th century, to the appearance of a path dependence situation around the auction. Then we describe the exogenou...

The auction system is the historical institution which has been used for timber sales in France for centuries. The recent trend to develop supply contracts through private agreements has a major impact on t...
Chapter

For centuries, and until recently, this sales mechanism was the only one that ensured the distribution of timber. However, due to the lack of competitiveness in the French ti...

Article
This paper, taking a socio-economic perspective, aims to better understand France's historical persistence in using auction to sell public timber. It focuses on the necessity to consider the evolution of merchant rules as the result of a social construction - wherein past choices influence the future - rather than a simple economic "cost - advantag...

Describing economic phenomena remains complicated because market exchanges are attached to a specific social context. Therefore, it seems relevant to apply an interdisciplinary strategy in order to explain the observed reality. The approaches supplied by New Institutional Economics, Socio-Economy and Economic Sociology partake of this desire to con...
