Abstract
The proposal for Basic Income (BI) pushed by renowned figures in Mexico sparked a vigorous debate over social policy between 2015 and 2018. This debate was particularly notable, as it challenged the long-standing dominance of conditional cash transfers, which had remained largely unquestioned as the country’s main antipoverty policy since their introduction in the 1990s. Despite the BI proposal getting wide coverage from the media, it not only failed to gain traction on the government’s agenda but also quickly became irrelevant right after the general elections of 2018. This was due to the unsuccessful coalition-building efforts of the BI proponents, who were unable to reconcile their political disagreements, overcome partisan competition, establish communication, and bridge their policy beliefs on various levels. By conducting interviews with relevant stakeholders, I conclude that the inability of the BI supporters to form a unified advocacy coalition made it impossible to promote social policy change.
