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).

Running the Analysis in Google Colab

Step 1: Upload Files to Google Colab

1. Go to Google Colab
2. Click File → Upload notebook and select dr_haiti_ipri_analysis.ipynb
3. Once the notebook opens, upload the data file:
   • Click the folder icon in the left sidebar
   • Click the upload button (document with up arrow)
   • Upload ipri_data.xlsx or ipri_data.csv

Step 2: Install Required Libraries (if needed)

The notebook uses standard Python data science libraries. If any are missing, run:

!pip install pandas numpy matplotlib seaborn scipy

Step 3: Run the Analysis

2. Or run sequentially: Use Shift + Enter to execute each cell in order

The notebook will:

• Load and validate the IPRI dataset
• Extract Dominican Republic and Haiti records
• Calculate institutional divergence metrics
• Generate statistical analyses (correlations, regressions)
• Create visualizations
• Export formatted results

Step 4: Download Results

After execution completes:

1. Click the folder icon in the left sidebar
2. Right-click generated files to download:
   • PNG visualizations
   • CSV data exports
   • Summary statistics
