* Significant at 10% level; ** Significant at 5% level; *** Significant at 1% level
Note:
Attribute: C-waste collector; F-frequency of waste collection; P-price of ECOSWAM service or user fee;
WTL-waste segregation, type/location of collector and mode of payment; ASCH-alternative specific
constant for households
When a household practices recycling, the attribute of waste segregation, type or
location of collection and mode of payment level two (WTL2) becomes significant.
This means, that, conditional on modified pick-up, such household’s utility is decreased
when the ECOSWAM service does not require waste segregation.
The greater the quantity of biodegradable waste a household generates, the more
likely it is to choose an option where waste collection is more frequent. This is true for
households that do not feed their biodegradable waste to animals, those who do not do
composting and those with little land to bury these wastes in.
The greater the quantity of biodegradable waste that a household generates, the
more price sensitive it is. It is more likely to choose an option with a lower garbage fee
or price. Households that dispose of their biodegradable waste by feeding these to
animals or by composting produce a less waste for collection and hence, prefer to pay
lower garbage fees.
Respondents with more years of schooling or those with higher educational
attainment are more price sensitive. They are not more likely to choose an option with a
higher price. However, the greater the EKAP score of the respondent, the more likely he
is to choose the ECOSWAM option with a higher garbage fee or price. Hence it is not
the number of years of formal schooling per se that make a respondent prefer a better
ECOSWAM option with a higher price but rather his EKAP score.
At “zero” level of income, the attribute of waste collector and collection vehicle,
C, is not significant. As the household income increases, the household’s utility is
increased when it chooses the option where the municipal truck and workers collect the
household’s waste rather than the barangay workers with a hired jeepney.
5.2.2 Business Establishments
Model 1 shows that the ECOSWAM attributes of waste collector and collection
vehicle (C), frequency of waste collection (F) and price (P) significantly influence the
business establishment’s choice of an ECOSWAM service. The positive coefficient of C
shows that a business establishment’s utility is increased when it chooses an option
where waste is collected by municipal workers with a municipal garbage truck. This is
because a truck has a larger capacity and is easily recognizable as the waste collection
vehicle as opposed to a rented jeepney. The business establishments also expect a more
reliable ECOSWAM service with a garbage truck because there may be times that the
jeepney hired to collect the waste would not be available.
The positive coefficient of collection frequency shows that the option where
waste is collected more frequently increases the utility of the business establishment.
Some business establishments are concerned with rotting garbage and sanitation so they
prefer garbage collection to be more frequent. The negative coefficient of the price
attribute shows that business establishments are price sensitive. An option with a higher
price decreases their utility.
