Executive Summary
Abstract
This project employs the Synthetic Control Method to analyze the causal impact of World Trade Organization (WTO) accession on national economies. By constructing synthetic counterfactuals for countries that joined the WTO between 1995-2015, we aim to isolate and quantify the economic effects of trade liberalization policies, providing robust evidence for the "echo effect" of WTO membership on economic development trajectories.
Research Question
What is the causal impact of WTO accession on key economic indicators (GDP per capita, trade openness, foreign direct investment, and institutional quality) in member countries, and how do these effects vary across different regions and development levels?
Key Research Objectives
Methodology
Constructs weighted combinations of control countries to create synthetic counterfactuals for treated countries.
Based on Abadie et al. (2010), this method addresses fundamental problems of causal inference in observational studies by providing a data-driven approach to counterfactual construction.
Addresses fundamental problems in observational studies through data-driven counterfactual construction.
Uses rigorous statistical methods to isolate the causal effect of WTO accession from other confounding factors and policy changes.
Comprehensive placebo tests and sensitivity analysis across different specifications.
Multiple validation techniques including placebo tests, sensitivity analysis, and alternative model specifications to ensure result reliability.
Treatment Definition
Treatment Variable
WTO accession (binary variable indicating membership)
Treatment Period
Year of official WTO membership (1995-2015)
Pre-treatment Period
10-15 years before accession for baseline establishment
Post-treatment Period
10-15 years after accession for effect measurement
Data Sources & Variables
Economic indicators including GDP per capita, trade (% of GDP), FDI, and other macroeconomic variables
Official accession dates and membership information
Democracy and governance indicators
Purchasing power parity and real income measures
Sample Selection Criteria
Treated Units
Countries that joined the WTO between 1995-2015
Control Pool
Countries that never joined the WTO or joined after 2015
Time Period
1980-2020 (40-year panel data)
Data Requirements
Countries with at least 20 years of complete data
Outcome Variables
- •GDP per capita (constant 2015 US$)
- •Trade as percentage of GDP
- •Foreign Direct Investment (net inflows % of GDP)
- •Institutional quality (Polity score)
- •Economic complexity index
- •Human development index
Expected Findings & Hypotheses
Hypothesis
Significant increase in trade openness following WTO accession
Expected Magnitude
15-25% increase in trade-to-GDP ratio
Theoretical Basis
Trade liberalization policies reduce tariffs and non-tariff barriers
Regional Variation
Stronger effects in developing countries with higher initial trade barriers
Hypothesis
Accelerated GDP per capita growth in the post-accession period
Expected Magnitude
0.5-1.5 percentage points annual growth acceleration
Theoretical Basis
Improved market access and efficiency gains from trade
Regional Variation
Larger effects in countries with complementary domestic reforms
Hypothesis
Enhanced governance and regulatory quality
Expected Magnitude
Improvement in Polity scores and regulatory indicators
Theoretical Basis
WTO membership requires institutional reforms and transparency
Regional Variation
Stronger effects in countries with initial institutional weaknesses
Hypothesis
Increased foreign direct investment following accession
Expected Magnitude
20-40% increase in FDI as percentage of GDP
Theoretical Basis
Improved investment climate and market access
Regional Variation
Larger effects in countries with significant market potential
