%description
Provides functions for optimal policy learning in socioeconomic
applications helping users to learn the most effective policies based on
data in order to maximize empirical welfare. Specifically, 'OPL' allows to
find "treatment assignment rules" that maximize the overall welfare,
defined as the sum of the policy effects estimated over all the policy
beneficiaries. Documentation about 'OPL' is provided by several
international articles via Athey et al (2021, <doi:10.3982/ECTA15732>),
