This research used a purposive sampling technique with a sample size of 18 companies for three consecutive years for a total of 54 observations. Partial research results show that agency costs and intellectual capital have no effect on firm value. Meanwhile, managerial ownership and institutional ownership have a positive effect on firm value.
