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, ), Kitagawa et al (2018, ),
Cerulli (2022, ), the paper by Cerulli (2021, )
and the book by Gareth et al (2013, ).
