Beyond Trade: How WTO Accession Reforms Fuel Long-Term Economic Expansion

The paper highlights that countries implementing deeper reforms during WTO accession negotiations experience faster, sustained economic growth. These reforms, beyond trade liberalization, lead to structural improvements and long-term benefits for member economies.

A study by Andre Brotto from the University of St. Gallen, Adam Jakubik from the International Monetary Fund (IMF), Roberta Piermartini from the World Trade Organization (WTO), and Fulvio Silvy from the University of Geneva, examines the economic consequences of joining the World Trade Organization (WTO). It explores how accession negotiations and the associated reforms impact economic growth across 150 economies. Unlike those under the General Agreement on Tariffs and Trade (GATT), the authors argue that WTO accessions involve more comprehensive and stringent reforms that extend beyond simple trade liberalization. These reforms often lead to structural and institutional changes that can have far-reaching economic benefits. To analyze this, they developed a Pre-Accession Commitment Index to track the timing and depth of reforms undertaken by countries during the negotiation process.

Faster Growth with Deeper Commitments

The paper finds that countries that engaged in significant reforms during WTO negotiations grew, on average, 1.5 percentage points faster than they would have otherwise. These growth effects are not short-lived; countries that acceded to the WTO continued to grow at higher rates even after their formal membership. The research emphasizes that the negotiation process itself, even before a country officially joins the WTO, can stimulate growth. This is largely because many reforms are implemented during the years leading up to accession, as part of the conditions set by the WTO. These findings are robust across a range of statistical tests, including instrumental variable estimations and falsification tests, indicating a strong correlation between WTO accession-related reforms and long-term growth.

WTO Membership Opens New Growth Channels

There are several mechanisms through which WTO accession leads to economic growth. One of the most immediate effects is the reduction of trade barriers, which boosts trade between the acceding country and the rest of the world. Numerous studies, including one by Larch et al. in 2024, have demonstrated that joining the WTO can increase trade significantly. This surge in trade is closely tied to higher economic growth, as expanded trade allows for better resource allocation, increased productivity, and access to new markets. Other research cited in the paper, such as work by Estevadeordal and Taylor, shows that lowering tariffs on intermediate goods leads to productivity gains for domestic producers of final goods. Another channel through which WTO accession promotes growth is through improvements in governance and institutional quality. As part of the accession process, countries often commit to reforms that align their policies with international standards. These reforms can include the reduction of subsidies, the elimination of state monopolies, and the introduction of intellectual property protections. By improving transparency and reducing uncertainty, these reforms create a more favorable business environment, which attracts foreign and domestic investment.

Structural Reforms and Long-Term Benefits

The empirical analysis in the paper demonstrates that the depth and pace of reforms undertaken during the accession process are crucial to the observed growth outcomes. Countries that made more substantial commitments during their negotiations grew faster than those that did not. The study also highlights the long-term benefits of WTO membership, showing that the positive effects on growth continue well after accession. Moreover, the research finds that countries begin to experience these growth benefits even before they formally join the WTO, during the negotiation period itself. This suggests that the reforms required for WTO accession, many of which are implemented during the negotiation process, play a significant role in driving economic growth.

The Importance of Comprehensive Accession Reforms

The authors further explore the heterogeneous impact of WTO accessions by comparing different types of accession processes. They find that countries that acceded under Article XII of the Marrakesh Agreement, which governs post-1995 WTO accessions, experienced more significant growth than those that joined the GATT under earlier, less rigorous processes. These findings underscore the importance of the structural and institutional reforms required for WTO membership. The paper’s analysis also includes robustness checks to address concerns about the potential endogeneity of the reform process. For example, the authors use instrumental variable techniques to isolate the impact of the WTO accession process on growth, and they conduct falsification tests to ensure the robustness of their findings. The results consistently show that the reforms undertaken during the WTO accession process are strongly correlated with higher growth rates.

WTO Accession: A Pathway to Sustainable Growth

The study provides compelling evidence that WTO accession can lead to substantial economic benefits, particularly when accompanied by deep and comprehensive reforms. The benefits of WTO membership are not limited to trade liberalization but also include broader economic modernization and institutional improvements. The paper's findings suggest that the rigorous reforms required for WTO membership serve as a catalyst for growth, helping countries develop more robust and competitive economies. This research highlights the role of international organizations like the WTO in fostering not only global trade but also long-term economic development through the promotion of sound economic policies and governance.
