This data set contains a Social Accounting Matrix (SAM) for the Mexican economy for year 2008. The Mexico SAM was built as the main data base for the calibration of a Computable General Equilibrium (CGE) Model, used to investigate the quantitative effects of climate change on the Mexican economy, with emphasis on analyzing its distributional impacts. Since the effects of climate change are mainly transmitted to the economy through the agricultural sector and since impacts on agriculture differ across regions, the Mexico SAM presents a significant disaggregation in the accounts referred to the agricultural activities and to income distribution, redistribution and income spending across households and regions. The construction of the SAM is described in Jemio, Andersen, Breisinger, Wiebelt (2015). Regional development, income distribution and gender in Bolivia - Insights from a 2012 Social Accounting Matrix (SAM) and Multiplier Analysis. IFPRI Data Paper. Washington, DC. The accompanying Data Paper presents the methodology and data sources used, assumptions made, criteria adopted to disaggregate the SAM’s accounts and the main results obtained.
