Using a choice experiment, this paper shows that the introduction of a conditional collective bonus in an agri-environmental scheme (AES) can improve farmers’ participation and increase land enrolment for lower overall budgetary costs. This monetary bonus is paid per hectare of enrolled land...

The paper presents a multi-agent model simulating a two-level public decision game in which politicians, voters and interest groups interact. The objective is to model the political market for influence at the domestic level and at the international level, and to assess how new consultation...

Multi-unit auctions are being used by public agencies to allocate resources and to purchase services. These auctions resolve the lumpy bid problem inherent in single-bid auctions by allowing bidders to submit a supply or demand schedule. However, the choice of pricing formats for multi-unit...

Emerging concerns for environmental flows translate into reforms that aim to preserve minimal flows in rivers. These policy measures have consequences for traditional right-holders: how to share between consumptive users the new scarcity created by the protection of instream flows? This paper...

La réforme de la PAC offre l’opportunité de proposer des pistes d’amélioration des mesures agroenvironnementales (MAE). L’analyse des facteurs de choix d’une MAE par les agriculteurs peut mettre en évidence les leviers mobilisables pour augmenter leur participation à ce dispositif....

Competition in a multi-unit auction is measured both by the number of bidders and by the relative size of their demands, compared to the number of units on sale. For the same degree of competition (identical aggregate demand and supply), we can observe different demand structures. Do they have...

Emerging concerns for environmental flows translate into reforms that aim to preserve minimal flows in rivers. These policy measures have consequences for traditional right-holders: how to share between consumptive users the new scarcity created by the protection of instream flows? This paper...

Is it better for a seller who wants to auction multiple units to face many small bidders or few large bidders? Since multi-unit auction models usually have many equilibria, there are no theoretical predictions on the impact of the competition structure on the performance of a multi-unit auction...
