Input-output models for regional demographic-economic analysis: some structural comparisons

Area of Science:

• Economics
• Demography
• Econometrics

Background:

• Static Leontief input-output models are foundational in economic analysis.
• Integrating demographic factors into economic models presents analytical challenges.
• Existing models vary in their representation of household income, employment, and unemployment.

Purpose of the Study:

• To comparatively survey extensions of static Leontief input-output models.
• To incorporate demographic-economic relationships within a unified framework.
• To analyze the structural relationships and impact multipliers of these integrated models.

Main Methods:

• Identification and classification of a family of ten input-output models.
• Generalization of Miyazawa's fundamental equation of income formation.
• Derivation and comparison of income and employment impact-multipliers across models.

Main Results:

• A systematic categorization of ten demographic-economic input-output models.
• Demonstration of structural relationships using generalized income formation equations.
• Quantification of differences in income and employment multipliers.

Conclusions:

• The study provides a comprehensive overview of integrated demographic-economic input-output models.
• Generalizing Miyazawa's equation offers a robust method for analyzing inter-model relationships.
• The findings facilitate a deeper understanding of economic impacts stemming from demographic changes.
