The study looked at how Colombia's peace negotiations impacted its economy, focusing on the Gross Domestic Product per person. By using a method called synthetic control, they found that the Peace Treaty boosted the GDP per person positively. Even after the treaty, Colombia's economy continued to benefit, and by 2021, it was in a better position compared to a hypothetical scenario where the peace negotiations didn't happen. The data suggests that the peace agreement had a lasting positive effect on Colombia's economy, helping it grow even in the post-pandemic period.
