Annualized implementation data on comprehensive intrastate peace accords, 1989–2012

This article introduces the Peace Accords Matrix Implementation Dataset (PAM_ID). We present time-series data on the implementation of 51 provisions in 34 comprehensive peace agreements negotiated in civil wars since 1989. We follow the implementation process for up to ten years following the signing of each agreement. The data provide new insights into the types of provisions that are more or less likely to be implemented, how implementation processes unfold over time, how implementation processes relate to one another, and how implementation affects various post-accord outcomes. We outline our coding methodology and case selection, and examine descriptive statistics. We illustrate one potential use of the data by combining eight different provisions into a composite indi-cator of security sector reform (SSR). A survival analysis finds that implementing security sector reforms contributes to long-term conflict reduction not only between the parties to the accord but also between the government and other non-signatory groups in the same conflict
