In No Strings Attached: The Behavioral Effects of U.S. Unconditional Cash Transfer Programs, we explore how unconditional cash transfers affected the behavior of recipients in three major natural experiments. While the amounts dispersed and time periods were distinct in each experiment, each provided money without set conditions and without a means test. We synthesize data for the following outcomes: consumption; labor force participation (employment, hours worked, and earnings); education; health; and other social outcomes, such as marriage or fertility choices. Each of these programs shares different components of a universal basic income (UBI), a cash transfer that everyone within a geographic/political territory receives on a regular basis with no conditions on a long-term basis. By understanding the effects of these programs, we can generate answers to how an unconditional cash transfer program might affect recipients in the future.
