GTAP Data Bases: GTAP Africa 2 Data Base

GTAP Africa 2 Data Base

    Cost: Free
What is the GTAP Africa 2 Data Base?
African policy makers are increasingly requesting quantitative assessments of trade agreements, such as the African Continental Free Trade Area (AFTA), the African Continental Customs Union (ACCU), and assessment of impacts resulting from external shocks such as international food and fuel prices. However, they have been fundamentally limited by data availability. In particular, international databases, such as GTAP, often have limited coverage of individual African countries. The Center for Global Trade Analysis, with assistance from the Bank Netherlands Partnership Program (BNPP) and the World Bank, has expanded the number of African countries available in the GTAP Data Base.

The GTAP Africa 2 Data Base includes data for 42 regions (32 African regions plus 10 other aggregated regions) and the 57 sectors of the GTAP 8.1 Data Base. New and updated I-O tables have been contributed with the help of African economists who were awarded scholarships to contribute this data and pursue research on African economic issues. The GTAP Africa 2 Data Base is packaged with the GTAPAgg aggregation software which is freely available for download after placing an order on the GTAP website.

MyGTAP Model and Data Programs
Policy analysis in the Africa region has increasingly required a focus on poverty and the distributional consequences of policy impacts. For example, policy makers want to know not only the national welfare impacts of a program or policy, but also the impacts on the poorest segments of the population, be they rural or urban poor. Understanding the distributional consequences of policies permits prioritizing policies which promote pro-poor growth.

The standard GTAP Model utilizes a "regional household" which gathers all income from taxes and factor returns and distributes these incomes into three entities: the private household, government, and savings\investment.

The MyGTAP model and data program provide a framework to eliminate the regional household and replace it with distinct representations of households and government linked directly to their income sources and tying these incomes to expenditures. It further provides the ability to expand the private household into multiple households, so distributional impacts are ascertained. Government income, expenditure and deficits are endogenously calculated and are explicit.

The MyGTAP suite is comprised of a modified version of the GTAP model and a data application, which facilitates splitting the regional household in the GTAP model into multiple factors, and households. It further augments the standard GTAP data flows with foreign aid, labor remittances, and foreign capital income. These feature are all bundled within the RunGTAP interface. Household analysis requires survey data or a disaggregated SAM for the region of interest, but maintains the global framework in non-subject countries. The MyGTAP suite is free of charge and accessible at http://www.gtap.agecon.purdue.edu/resources/res_display.asp?RecordID=3810.
