The WTP estimates are obtained as the ratio of the / of the attribute in question relative to the B of price, e.g. WTP of preserving native species, with a stable European development at the level of 'Abundant' is: WTP = ANSA/BP. Note not all decimals shown. Columns 3-5 show preference coefficients, standard errors and p-values for the combinations of species groups and future policy outcome in Denmark (DK) in column 1 and 2. Columns 6-7 shows the related mean Willingness to Pay (WTP) estimates (E/household and year) and standard error of this. doi:10.1371/journal.pone.0101281.1001 150 150 100 100 Stable WTP WTP 50 50 70 3 2 93 Native Immigrants Native Immigrants European population is 150 150 Declining 100 WTP 96 111 150 50 Native Immigrants Native Immigrants Local policy results in populations that are Scarce Abundant 1) Describe at least 5 interesting results from the tables (extra point, up to 3, for each result beyond that) (10 points) 2) The researchers show three options to choose from. Is it correct? Which principle are they violating? (2 points Would there be any way that you could do this study with a revealed preference method? Explain (5 points ) Look at the choice card: what are the attributes taken into consideration? (8 points) 5) Give at least 3 comments as to how the choice card could have been better (10 points)6) From the paper, the researchers say: \"The respondent data were collected through the internet. Respondents were drawn from an internet panel consisting of a representative and voluntary sample of the Danish population." Is this probability or non-probability sampling? Give 3 shortcomings that this way of sampling creates (10 points) 7) As most choice experiments, this study was conducted to provide policy-relevant information. Using the results shown, provide 2 policy implications. (5 points) Part 2: Case Study Lundhede et al. (2014) apply the choice experiment method in a study of the preferences of Danish people for bird conservation policy, in the context of the pressures brought about by climate change. The figure below gives an example of the choice cards used in their analysis.
