The United Nations General Assembly (UNGA) represents a microcosm of global politics that offers a valuable snapshot of interstate relations and state preferences. In this context, roll-call votes and measures of voting affinity often receive the bulk of scholarly attention. However, even though techniques such as ideal point estimation have grown more sophisticated over time when applied to voting data, they remain grounded by an original selection bias that discards 2/3 of the UNGA yield. This share of disregarded output can prove highly informative if drafting and sponsorship procedures receive a closer look instead. This research note applies ideal point estimation to UNGA sponsorship data for the first time for every member from 2009 to 2019. It advances a cutting-edge approach to better estimate state preferences over a contested policy space, while correcting for the narrow focus of previous UNGA analyses on voting data. The results detect an underlying issue space that bears external validity with the inclination of states toward multilateralism.
