The use of deliberative methods to assess environmental values in monetary terms has been motivated by the potential for small group discussion to help with preference formation and the inclusion of non-economic values. In this review, two broad approaches are identified: preference...

This paper presents an optimal control model to analyze reforestations with two different species, including commercial values, carbon sequestration and biodiversity or scenic values. We solve the model qualitatively with general functions and discuss the implications of partial or total...

Stated preference (SP) surveys have been conducted to value non-timber benefits (NTBs) from forests in Norway, Sweden and Finland for about 20 years. The paper first reviews the literature and summarises methodological traditions in SP research in the three countries. Second, a meta-regression...

In a travel cost exercise, reported past visits to mount Jaizkibel, a natural area located in the Basque Country (Spain), are compared for convergent validity to stated intended future trips under the assumption that the natural resource's conditions will remain the same. In line with the...

This paper examines the role of simplified heuristics in the formation of preferences for public goods. Political scientists have suggested that voters use simplified heuristics based on the positions of familiar parties to infer how a proposed policy will affect them and to cast a vote in line...

Non-market valuation (NMV) is recognized as an essential tool in policy decision making worldwide. In this paper, we investigate the history of NMV, specifically in relation to New Zealand (NZ), by compiling and analyzing all available published studies. Results show a significant increase in...
