Individuals first participated in an online survey. To
assess environmental and local NBs, four, seven-point
Likert statements were used for each (see Appendix 1).
These included statements asking individuals to rate
whether they (and people in general) should buy and
be willing to pay more for environmental (local)
products. Preceding the survey statements, individuals
were given (in randomized order) general information
about the environmental and local products movements,
as well as how coffee is produced in each movement
(see Appendix 2).
The contingent valuation method assessed participants’
stated WTP (WTP intentions). Individuals were
given a reference price of $8 per 12-ounce package, and
reported their WTP for the organic and local coffees
(Loureiro 2003). They could put any price they chose,
including a price less than the benchmark. This benchmark
was developed using the average price consumers
actually pay for coffee at the local supermarket utilized
for this study, and by Trudel and Cotte (2012).
Each participant was told that a $10 store gift card
would be awarded after the auction, which represented
the second part of the study. Fees such as this may be
considered endowments biasing WTP estimates
(Harrison 1989). However, Loureiro, Umberger, and
Hine (2003) concluded that an endowment close to
the value of the auctioned good should not signifi-
cantly impact WTP estimates. Therefore, taking into
account travel expenses, time to complete the auction
(one hour), and the reference price stated above, the
$10 gift card should not significantly bias the results.
