WTO Working Papers

In this paper we explore the impact of decarbonization on international trade and development employing a recursive dynamic Computable General Equilibrium (CGE).

As digital trade becomes an increasingly vital component of the global economy, identifying the impact of wider international cooperation on digital trade issues becomes a growing policy imperative. This paper seeks to provide a quantitative analysis of the potential economic impacts of concluding the WTO Agreement on E-commerce (AoE).

This paper examines the evolution of global merchandise trade, between 2010 and 2022, assessing the share of imports subject to regional trade agreements (RTAs). A key question for us is whether the share of merchandise trade subject to preferences has kept pace with the proliferation in RTAs. The paper finds that with the growing number of RTAs over the period, the share of the total volume of global imports involving RTA partners increased from 37% in 2010 to 52% in 2022. However, potential preferential imports between them under RTAs remained relatively stable, rising slightly from almost 17% in 2010 to 23% in 2022.

This paper explores the application of Natural Language Processing (NLP) techniques to automate Harmonized System (HS) tariff line transposition, employing a three-stage process: unique 1:1 tariff code matching (Round 1), exact description matching (Round 2), and “smart” description matching (Round 3) using Artificial Intelligence (AI) and lexical similarity methods paired with harmonized 6-digit concordance and cosine similarity. Similarity is calculated using either Term Frequency Inverse Document Frequency (TF-IDF) vectors or Sentence-BERT (SBERT) embeddings, comparing two scenarios: a straightforward case (Economy A) with standardized descriptions, and a complex case (Economy B), with more detailed technical descriptions.

We explore a global carbon pricing framework to inform the potential coordination of carbon pricing and equivalent policies. The framework has three main features aligning with the current multilateral system for climate action. First, the carbon price is determined by a global average carbon price to achieve emission reductions required to remain on a 1.5-2 degrees Celsius global warming trajectory.

Some countries have voiced unease about differences between their own tariff rates and those of major trading partners, calling for more ”reciprocity”. These calls raise the question how large the negative spillover effects of countries’ tariffs on others have become over time.

The WTO Trade Facilitation Agreement (TFA) has been predicted to bring about an expansion in trade flows and real income gains. To date, there is still very limited empirical evidence on the actual post-implementation impact of the TFA. This paper provides an assessment, combining econometric estimations from a structural gravity model with general equilibrium modelling results.

In this study, we investigate three trade policy scenarios: i) the revival of multilateralism, ii) plurilateral cooperation, and iii) geopolitical rivalry. In the first scenario, both tariffs and NTMs are reduced on a multilateral basis. In the second scenario, varying groups of countries cooperate on specific topics, such as E-commerce and services. In the last scenario, two main blocks emerge: a Western block and an Eastern block. International cooperation breaks down between blocks, leading to an increase in tariffs and NTMs, with blocks of countries setting up their own set of rules. Our findings are based on simulations with the WTO Global trade Model which has a specific novel feature: the diffusion of ideas between countries as a by-product of trade.

The scheduling approach constitutes a key element of services trade agreements as it is the means to pursue liberalization. This paper provides an overview of the scheduling approaches adopted in 187 trade agreements notified under GATS Article V as of 30 April 2022, analyses the differences between the positive and negative list approaches, and discusses their implications for negotiation strategies and trade policies.
