In this article, we review the desirability and feasibility of a universal basic All rights reserved income (UBI) scheme from the theoretical point of view. We first discuss the JEL codes: D31, D63, H24, H31, I38 possible theoretical justifications of UBI, contrasting the unconditionality This article is part of a symposium on Universal of UBI with the many conditions that typically accompany other welfare Basic Income. For a list of other articles in this policies. These justifications range from pure normative reasons to practical symposium, see http://www.annualreviews.org/ doi/full/10.1146/annurev-ec-11. reasons due to the problem of screening beneficiaries and imperfections in institutions in charge of implementing tax and welfare policies. Next, we explore the conditions that determine the feasibility and size of a UBI. The broad picture that emerges from our review is that both normative and practical considerations make UBI easier to defend as a tool of poverty alleviation in developing countries than as a tool to achieve social justice in developed ones.
