title: Shared Island, Divergent Institutions: The Dominican Republic as Counterfactual Evidence for Legal Infrastructure Investment in Postcolonial Civil Law Systems

description: Dominican Republic-Haiti Property Rights Institutional Divergence Analysis

Overview

This repository contains a complete replication package for the statistical analysis comparing property rights institutions between the Dominican Republic and Haiti from 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).
