Yet, energy contracting markets grow slowly and Switzerland is lagging behind. In order to assess whether the potentials are under-exploited, the determinants of energy supply contracting adoption are assessed using a random effects probit model on a dataset of 2,003 accepted and rejected contracts in Switzerland. Results show that the advantages of risk sharing and economies of scale brought by contracting as well as trust towards the supplier and the technology seem determining in the client's choice. The number of interlocutors involved, inducing higher expected adaptation costs, impacts negatively adoption. Less specific contracts involving residential or new buildings are more likely to be signed. The results imply that in order to fully exploit the potentials of contracting, a priority is to clarify to which extent owners can transfer the costs onto the tenants. Information campaigns are still needed to reduce the lack of confidence in energy renewable technologies. This study also provides the suppliers with guidelines to better exploit the market.

The river’s biodiversity is nowadays threatened by pollution and large flow variations caused by hydropower plants. A hypothetical travel cost method is used, to estimate the economic value of recreational fishing in the Doubs under the current situation (2010) and under a hypothetical improvement. Thus, 225 anglers stated in a mail survey (June 2011), their behavior under the two situations. Since each angler reported the number of visits for up to 3 fishing sites, a correlated random effects model could be estimated. This method allows a better control for unobserved heterogeneity. By comparing consumer surplus estimations under the two situations, the annual benefit of an improvement in water quality and flow regulation ranges, from 1450 CHF to 1700 CHF per angler. Since recreational use is only a small part of the total economic value of the river, these estimations are not sufficient to give a complete measure of the economic benefits of the river’s restoration. However, an ex ante appraisal of a part of these benefits is useful for policy makers for comparison with eventual costs of restoration.
