Session 3: Preferences and Economic Valuation

a slide showing the information below on this session

Chaired by Silvia Ferrini from the University of East Anglia, the panellists for this session presented their research and subsequently engaged in a Q&A session. Here are short summaries of the research they presented:

  • Diana Quispe, from the Universidad Nacional Micaela Bastidas of Apurimac, discussed her results on ‘Environmental valuation of elements of biodiversity in the Titicaca National Reserve’. Using choice experiments, her paper explores the differences in the valuation of elements of biodiversity, offering a monetary and non-monetary approach in rural and urban population groups. The results show that the monetary WTP differs by population group and valuation approach and concludes that the way of valuing biodiversity is important.

 

  • Presenting ‘Testing the stability of preferences in the time of the Covid-19 pandemic: A three-way cross country choice experiment for sustainable chocolate bars’Gaetano Grilli from the University of East Anglia discussed his proof of the reliability of stated preference applications for informing policy decisions. Using chocolate as a product that holds trade-offs between pro-self and pro-social preferences, the study shows the stability of preferences and welfare values in choice experiments.

 

  • Silvia Ferrini from the University of East Anglia discussed the question ‘What is the value of EU habitat and species maintenance policy? From model results to policy uses.’ Her work explores the non-use values of biodiversity in Europe. The results show a WTP between €28 – 276 per year per family, justifying higher investments in biodiversity maintenance and showing uneven conditions of European natural environment, attitudes, and policies.
