This report is presented as a nascent effort to catalogue the socioeconomic impact of excessive pretrial detention around the world. As discussed in Section II, precise data on pretrial detention are rare. Rarer still are rigorous cost (or cost-benefit) analyses of pretrial detention. Although there are extant studies from Mexico (summarized in Appendix 1), Chile, Argentina, and Ukraine, the literature is thin. This report, then, may be seen as both an initial foray and an appeal for additional research.
