A Flexible Modeling Framework to Estimate Interregional Trade Patterns and Input-Output Accounts
This study implements and tests a mathematical programming model to estimate interregional, interindustry transaction flows in a national system of economic regions based on an interregional accounting framework and initial information of interregional shipments. A national input-output (IO) table, regional data on gross output, value-added, exports, imports and final demand at sector level are used as inputs to generate an interregional IO account that reconciles regional economic statistics and interregional transaction data. The model is tested using data from a multi-regional global input-output database and shows remarkable capacity to discover true interregional trade patterns from highly distorted initial estimates.
Summary: | This study implements and tests a
mathematical programming model to estimate interregional,
interindustry transaction flows in a national system of
economic regions based on an interregional accounting
framework and initial information of interregional
shipments. A national input-output (IO) table, regional data
on gross output, value-added, exports, imports and final
demand at sector level are used as inputs to generate an
interregional IO account that reconciles regional economic
statistics and interregional transaction data. The model is
tested using data from a multi-regional global input-output
database and shows remarkable capacity to discover true
interregional trade patterns from highly distorted initial estimates. |
