Enhancing the Links Between Income Sources, User Expenditures and Taxes in a CGE Database

Part of the Advances in Applied General Equilibrium Modeling book series (AAGEM)


A Computable General Equilibrium (CGE) model that is relevant to policy makers requires a highly detailed, multi-dimensional database. Even a single-region model with many industries—100 is typical in policy-focused research—will require a database with several hundred thousand elements. The data is subject to many constraints: commodity and factor markets must clear and income, savings and expenditure must balance for every agent. It is therefore advisable that the data is arranged in a framework that clearly illustrates these requirements. A popular framework that meets these needs is the social accounting matrix (SAM) . This chapter describes an alternative framework, which readily fits in with the existing format of the standard input–output table.
