A Flexible Mathematical Programming Model to Estimate Interregional Input–output Accounts*
نویسندگان
چکیده
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 multiregional global IO database and shows remarkable capacity to discover true interregional trade patterns from highly distorted initial estimates.

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.

متن کاملDesign for Commodity-by-Industry Interregional Input-Outpu–
In this paper we do not attempt to develop an interregional model. Rather, we propose a mathematical structure of computational framework with which a family of interregional input-output models can be constructed. This family of interregional input-output models encompasses the well-known class of static models that are used to analyse the propagation of demand throughout an economic system di...
متن کاملThe Effect of Changing Interregional Relationships on Employment Changes: A Decomposition Analysis in Two-Regional Input- Output Model
According to the regional economic literature, interregional communication can play an important role in production, followed by production-related variables such as employment. For this reason, changing (strengthening or weakening) inter-regional communication can lead to changes in production and employment in the regions. Accordingly, the purpose of this study is to investigate the change of...
متن کاملClassifying inputs and outputs in interval data envelopment analysis
Data envelopment analysis (DEA) is an approach to measure the relative efficiency of decision-making units with multiple inputs and multiple outputs using mathematical programming. In the traditional DEA, it is assumed that we know the input or output role of each performance measure. But in some situations, the type of performance measure is unknown. These performance measures are called flexi...
متن کاملUniquely classifying flexible measures by a CWS model
Data Envelopment Analysis (DEA) deals with evaluating a set of decision-making units (DMUs) based on nonparametric mathematical approaches. In classical DEA models, the given set of factors of DMUs is divided into two categories, inputs and outputs, while in some practical problems there are some measures whose membership to these categories is unclear. It means these factors treat different in...
