Stability and Evolution of Preferences for Improved Cookstoves : A Difference-in-Difference Analysis of a Choice Experiment from Ethiopia

description |
There is a growing effort in the
non-market valuation literature toward better understanding
of the stability and evolution of preferences over time. The
study uses a novel approach combining a repeated choice
experiment with a randomized controlled trial on stove
adoption in Ethiopia to analyze the stability and evolution
of preferences. The treatment group in the randomized
controlled trial received an improved fuelwood stove with
less fuelwood use, whereas the control group continued to
use traditional cooking methods. Respondents were given the
exact same choice questions in 2013 and 2016. The study
began with 504 households in 36 communities in 2013, and 486
of the same households participated in 2016 (a 96 percent
retention rate). The results show that preferences of the
respondents from the control group are stable over the study
period, while preferences of the respondents from the
treatment group evolve. Moreover, households in the
treatment group still using the stoves have significantly
higher willingness to pay for all the stove's
attributes in 2016 compared with 2013, indicating how longer
experience can increase the willingness to pay for
technology with environmentally preferable attributes. |
