Dominican Republic-Haiti Property Rights Institutional Divergence Analysis Overview This repository contains the complete replication package for a comparative analysis of property rights institutions between the Dominican Republic and Haiti (2007-2025), using International Property Rights Index (IPRI) data. Key Finding: The analysis documents a 106.6% expansion in the institutional gap between the two countries, with Physical Property Rights (PPR) accounting for the largest divergence (3.60-point gap in 2025).
