2018 Training Course - Trade Analysis Methodologies

Event Date: 
14 Nov, 2018 - 15 Nov, 2018 
Location: 
Dakar, Senegal 

 

Overview

AGRODEP is pleased to announce a training course on tools and methodologies for trade policy analysis. The four-part course covers:
  1. Measuring Trade Integration with Trade Flow Indicators
  2. Measuring Trade Integration with Gravity Models
  3. Partial Equilibrium Models for Trade Analysis
  4. Simulation Models for Assessing the AfCFTA: PE vs CGE, Aggregation Issue, and Public Revenue
The course is intended as a refresher training on trade analysis tools and methodologies for the members of the AGRODEP African Continental Free Trade Area (AfCFTA) Task Force, a group currently composed of several AGRODEP members who can readily be engaged in activities related to analysis of regional integration issues under the AfCFTA.  
 

Course Information

Part 1: Measuring Trade Integration with Trade Flows / Trade Indicators

 
From the analyses of trade integration in Africa based on trade costs (direct measurement), we conclude that these costs are relatively high in this continent, particularly import duties, transportation costs, documentary compliance costs, and border compliance costs. The indicators based on trading costs evaluate whether or not the necessary conditions for trade integration are met. Additional indicators are necessary to measure whether trade integration is actually effective, in particular indicators based on trade flows.
 
The four-hour training presents indicators based on trade flows, outlining their interpretation and raising criticisms: trade-to-GDP ratio, symmetric indicator of relative openness, corrected degree of openness, indicators from the network literature, diversification indexes, and indicators measuring regional integration like the simple trade-based regional indicator, the intraregional trade intensity index, the modified intra- and extra-regional intensity index and the regional trade introversion index. All these indicators will be applied to the most recent version of the BACI database with a special focus on Africa.

Part 2: Measuring Trade Integration with Gravity Models

Instructor: Luca Salvatici
 
Over time, the gravity model has been defined as the workhorse of international trade and its ability to correctly approximate bilateral trade flows makes it one of the most successful “empirical fact” in economics. With data increasingly available for developing, as well as developed countries, the gravity model has come to be the starting point for a wide variety of research questions with a policy component. The gravity model has more recently acquired a range of micro-founded theoretical bases, showing that the typical gravity equation should account for both “bilateral resistance” and the so-called “multilateral resistance” term (MTR). The recent literature emphasizes the importance of expressing trade policies through continuous variables since they vary widely across products, importers and exporters. Moreover, in the case of non-quantitative trade policies, such as non-tariff measures, the gravity model is widely used to provide an assessment of the policy intensity.
 
The four-hour training intends to provide African-based researchers with knowledge of the latest developments regarding both theoretical general equilibrium foundations for the gravity equation for trade and empirical strategies leading to more accurate estimation and interpretation of the policy impact. After a review of the theoretical foundation of gravity models, we will then turn to the discussion of advanced issues on gravity modelling such as how to handle zero-trade flows and how to account for intra-national trade flows. Finally, we will discuss possible extensions of the gravity model using different dependent variables, e.g. trade in value-added rather than gross terms, and its relationship with other econometric methods, such as matching.

 Part 3: Partial Equilibrium Models for Trade Analysis

Instructors: Antoine Bouet and David Laborde
 
The main goal of simulation models is to perform ex-ante analysis of various economic policies (e.g. investment decision in agricultural R&D in different sectors, potential effects of a trade agreement) or to disentangle different effects of existing policies (e.g. interaction between export taxes and import duties in international trade relations). Simulation models include Partial Equilibrium models and Computable General Equilibrium models, both in deterministic and stochastic versions, working in a static or a dynamic framework.
 
Partial equilibrium (PE) models are based on a restricted range of data. They examine the effects of policy action in creating equilibrium only in that particular sector or market which is directly affected, ignoring its effect in any other market or industry. One example of a PE model is a supply and demand where market clearance for a specific product is obtained independently from prices and quantities in other markets; the prices of all other products (including substitutes and complements) and income levels of consumers are held fixed in the analysis.
 
The four-hour training provides an overview of four partial equilibrium models available in the AGRODEP model library. The partial equilibrium model for trade policy analysis (PE-TRADE) shows multiple examples of trade policy analyses scenarios with increasing level of complexity in each Excel worksheet. The Partial Equilibrium Trade Simulation (PETS) model is a multi-region, multi-sector, dynamically recursive, and partial equilibrium model. The AGRODEP Spatial Equilibrium model is a multi-region, partial equilibrium models which links producers and consumers from different locations. Different from many single-commodity partial equilibrium models, the Export Restrictions And import Tariffs Overall impacts (ERATO) model illustrates how a multi-market model can be used to analyze trade policy options in a context of a multi-product value chain.

Part 4: Simulation Models for Assessing the AfCFTA

Instructors: David Laborde
 
Building on the refresher course on partial equilibrium models, the training course focuses on computable general equilibrium (CGE) models and issues related to CGE modelling. CGE models differ from PE models in that the analysis looks at the economy as a complete system of interdependent components, including households, firms, government, exporters, importers, etc. The analysis captures the ripple effects of an economic shock in one component throughout the system. The benefits of using CGE analysis include accounting and theoretical consistency, backward and forward linkages across sectors or industries, and welfare analysis. 
 
The four-hour training covers a comparison of partial equilibrium versus computable general equilibrium modeling and other important issues to consider in the CGE modeling of regional integration initiatives such as the AfCFTA. These issues include the tariff aggregation issue and fiscal implications of regional integration.
