Integration of multiregional models for policy analysis

An initial conceptual framework is presented for the integration of a number of multiregional models, and a modular structure is outlined. This structure consists of a national econometric model; an integrated comparative cost, industrial complex, input - output, and programming module; a transportation module; a demographic module; a multiregion econometric module; and a factor demand - investment supply econometric module. Fruitful directions for partial or full integration of these modules are suggested with particular emphasis on intermodule and intramodule linkages and on several necessary consistency checks.
