DEVELOPMENT OF REGIONAL SOCIAL ACCOUNTING MATRICES WITH DETAILED AGRICULTURAL LAND RENT DATA AND IMPROVED VALUE-ADDED COMPONENTS FOR THE USA

We describe a method for creating social accounting matrices (SAMs) with detailed agricultural land rent data for any arbitrary subset of the 48 contiguous states in the USA. Data on land use and land rents from various public sources is merged with national accounts data. The method reorganizes the rental income of persons concept present in national accounts to payments to conventional primary factors of production. This method also reallocates portions of the indirect business tax account to the appropriate sales and import tax accounts. SAMs created using this method should be useful inputs into input-output or computable general equilibrium models explicitly representing a heterogeneous land market and analyzing the economic effects of agricultural, bioenergy, water and climate policies on land-use change, land rents, agricultural commodity markets, trade and households' welfare. The method's implementation is freely available, enabling others to rapidly create SAMs with their own desired region and sector aggregations.
