First, the dummy variable of advices (adv) takes unity if
the household receives specific advices on forest management
from Perum Perhutani, and zero otherwise. Some field staffs of
Perum Perhutani regularly hold meetings with community
members to deliver advices on forest and agriculture managements,
while others visit villages and give advice on the individual
basis in an ad hoc manner.7 The meeting and visit to the villages for advice would encourage local farmers to participate
more in the program, so the coefficient on advice (adv) should be
positive.
