Caputo, Richard K. (2007). "The Unconditional Basic Income Guarantee: A Preliminary Assessment of UBIG Political Viability around the Globe" Paper presented at the 4th annual conference of the HDCA, 18-20 September 2007, New York, USA.

The paper presents preliminary findings of the author’s investigation of the political viability of UBIG schemes around the globe over the past twenty years.Brazil not withstanding, the evidence thus far suggests that the idea of unconditional basic income to all adults as a policy has little political tractability among mainstream political groups. However, in several countries where BIG was considered among major political parties alternative legislation targeting specific groups such as children from poor families or older persons has greater promise.
