This paper discusses how to develop and manage integration, coordination and cooperation (collective action) in bio-energy supply chains. Farmers decision on whether or not to participate in a contract farming scheme have been investigated, particularly assessing the trade-offs between the contract attributes and their impact on the likelihood to participate. A stated preference model has been implemented where respondents were asked to choose between alternative contracts with varying attribute levels to start biomass cultivation. Results show that participation is mainly influenced by minimum price guaranteed, contract length, and re-negotiation before the end of a contract.
