1 Using WITS with UNCTAD TRAINS Trade Analysis and Information System For the DATA Day at WTO Geneva, May

2 WITS vs TRAINS WITS is a software application which is designed to integrate several trade-related databases and provide easy access TRAINS is one of the four major databases currently accessible through WITS

3 Databases of WITS TRAINS (UNCTAD) COMTRADE (UN Statistics Division) Integrated Database (IDB-WTO) Consolidated Tariff Schedule (CTS- WTO)

4 Data Accessibility COMTRADE: Free access to International Organizations, others against a fee TRAINS: Access to governments and international and regional organizations, as well as to donors to TRAINS Trust Fund WTO: Access to WTO member governments and selected international organizations

5 Data contents of TRAINS (as of 1 May 2009) Tariff measures at national tariff line level for 165 countries (over 1000 country/years since 1988), including preferential rates such as RTA and GSP in many cases Primary data are drawn from UN TARMAC UN Tariff and Market Access Database A joint effort with the International Trade Centre, UNCTAD/WTO (ITC)

6 Data contents of TRAINS (continued) Import statistics by origin at Harmonized System (HS) 6-digit level for every country- year by constructing mirror imports where necessary Non-Tariff Measures classified according to UNCTAD Coding System of Trade Control Measures (97 countries, 150 country/years)

7 WITS Functionality Data retrieval and analysis Advanced query Tariff Change Simulations Trade Effect Simulation Data Download (Quick DatabaseQuery)

8 Advanced Query Users construct queries comprising of: –Reporter countries –Products –Partner countries –Years

9 Advanced Query – Parameters Reporter Countries –Individual countries or user-defined groups of countries Products –Individual products or user-defined aggregates of products in various product classifications (HS, SITC,ISIC, etc)

10 Advanced Query – Parameters Partner Countries –Same as Reporter Countries. World is treated as an individual country Years – From 1988

11

12 Assumptions: –Each product is independent –A same product from different supplier is an imperfect substitute –Three sets of elasticties (Demand, Supply and Substitution between two suppliers) Trade Effects Simulation ( Single market simulation model)

13 Advance Tariff Change Simulation (ATCS) Apply tariff change formula to tariff schedules and assess impact on Bound/Applied Rates Pre-defined or user-defined formula Multiple formula in terms of affected countries and products
