categories: 1 = live near landfill and new incinerator site, 0 = not near),
education (coded to 3 categories: primary and below, secondary or post-
secondary), age (coded to 6 categories: 18–24, 25–34, 35–44, 45–54, 55–64
and ≥65 years), household size (coded to 6 categories: 1, 2, 3, 4, 5, 6 and
above), type of living quarters (coded to 3 categories: “public rental housing”,
“subsidized home ownership housing”, or “private housing and others”),
monthly personal income (coded to 3 categories: “under HK$15K,” “HK$15K
and under HK$30K,” and “HK$30K and above”).

3. Result
Characteristics of the respondents
The sample consisted of 40% males and 60% females. A majority of the
respondents (at least 81%) did not live near the landfill sites and the new
incinerator. Around 80% of the respondents received secondary school or
above education. The average age and monthly personal income of the
respondents were 47.07 years and HK$13, 151 respectively. More than 60% of
the respondents lived in subsidized home ownership housing and private
housing. As the effect size (Cohen 1992) of gender, residential district,
education, age, type of living quarters and monthly personal income fell
between 0.01 and 0.24 based on the population data in 2013 (Census and
Statistics Department 2014), the sample was generally representative of the
population of the residents in Hong Kong.
Approximately one third of the respondents were willing to pay less than
HK$30 (36.1%), exactly HK$30 (32.4%) and more than HK$30 (31.4%) for waste
disposal respectively. The monthly average WTP was HK$38.4, which is slightly
above the minimum waste charge amount of HK$30-$60 estimated by the
Council for Sustainable Development in Hong Kong.
More than half of the respondents (51.1%) were able to answer correctly
that the government preferred quantity-based waste charge method. Few
respondents knew that one of the landfills would be full around 2015 (22.7%)
and it would take 7-9 years to build new incinerator (7.3%). More than half of
the respondents indicated support for waste charge, landfill extension and
building a new incinerator proposals (52%, 54% and 69% respectively). About
60% of the respondents disposed one waste bag each day.
