A gradual move towards greater universality may also be desirable in countries where poorer population groups receive relatively small shares of overall benefit expenditures. Another alternative would be to keep mild eligibility conditions in place or have durations of basic income payments capped. A further option could be to introduce it gradually to different groups, such as future cohorts of young adults (OECD, 2017b, Browne and Immervoll, 2017).
