Abstract
Preventive detention legislation allows for the ongoing detention of an offender's
sentence. We explore the effects of pretrial detention on case outcomes in Bogota,
Colombia, from 2005-2017. Using pretrial judge leniency as an instrument, we find
that pretrial detention leads to a 48 percentage point increase in the likelihood of
being convicted. The rise in the probability of reaching agreements among defend-
ants who would have otherwise been acquitted or had their charges dropped explains
our findings. We also find evidence of an increase in the likelihood of pleading
guilty for those detained pretrial and who experience a more significant incarcera-
tion sentence. Colombian prisons are overcrowded. Pretrial detentions add to the
cost of maintenance of the prisoners. Policymakers should consider whether the
costs associated with pretrial detention outweigh the potential benefits.

justice, or pose a significant threat to society or the victim (Law 906, Article 308,
