Abstract
Researchers have puzzled over the finding that countries that ratify UN human rights treaties such as the Convention Against Torture are more likely to abuse human rights than non-ratifiers over time. This article presents evidence that the changing standard of accountability – the set of expectations that monitoring agencies use to hold states responsible for repressive actions – conceals real improvements to the level of respect for human rights in data derived from monitoring reports. Using a novel dataset that accounts for systematic changes to human rights reports, it is demonstrated that the ratification of human rights treaties is associated with higher levels of respect for human rights. This positive relationship is robust to a variety of measurement strategies and model specifications.
