The framework presented in this section is based on Pannell (2008), Public benefits, private benefits, and policy intervention for land-use change for environmental benefits, Land Economics (forthcoming), see www.sif3.org 
Having established that market failures exist, we next need to establish that the benefits of intervention will exceed intervention costs. It is not anticipated that the NRM manager would at this step develop a detailed quantification of likely benefits and costs of policy intervention. Rather, the intention is to establish whether a policy intervention is likely to be warranted and to help guide instrument choice. For example, in some cases, it may be that the public benefits of intervention may not be sufficient to warrant the necessary management changes and associated costs.
Through considering likely costs and benefits, opportunities for the use of MBIs will be:
- to encourage a positive NRM change where there are private costs to the firm or land manager of undertaking change but greater public benefits —that is, a net social benefit when all costs and benefits are considered; or
- to discourage a negative NRM change where there are private benefits to the firm or land manager of undertaking certain NRM practices but even greater public costs — so, again, there would be a net social benefit from policy intervention when all the costs and benefits are considered.
