RT Journal Article T1 The impact of protest responses in choice experiments: an application to a Biosphere Reserve Management Program A1 Barrio, Melina A1 Loureiro García, María Luz K1 Biosphere Reserve K1 Choice experiments K1 Protest responses K1 Willingness to pay AB Aim of study: To identify protest responses and compute welfare estimates with and without the inclusion of such responses using follow-up statements in a choice experiment exercise. To our knowledge, this is one of the first empirical applications that, following the conventional treatment used in contingent valuation methodology, explicitly deals with the treatment and identification of protest responses in choice experiments.Area of study: the Eo, Oscos y Terras de Burón Biosphere Reserve sited between the regions of Galicia and Asturias. We are interested in the influence of such responses on preference elicitation for alternative management actions in this Reserve.Materials and methods: A face-to-face survey conducted in a sample of residents and non-residents of this Reserve. In total, more than 450 surveys were collected.Main results show that protest responses are fairly common in choice experiments, and their analysis affects the statistical performance of the empirical models as well as the valuation estimates. In fact, when the sample is corrected by protest responses, its size decreases to 303 individuals. Furthermore, we can observe that protest responses are triggered by a less positive attitude towards the wolf.Research highlight: Protest responses are a common issue in choice experiments and, therefore, future exercises should consider them explicitly, as earlier contingent valuation studies have.
