| † A protest response is one in which respondents choose the status quo scenario in all presented choice sets, not because they have zero willingness-to-pay for the environmental services provided by indigenous people but because of other reasons (see e.g., Meyerhoff and Liebe 2009 for more details on how to handle protest responses). | |||
