Input-output analysis

Definition

Input-output analysis is a quantitative economic technique that represents the relationships between different sectors of an economy, detailing how outputs from one sector serve as inputs for another. This method helps in understanding the flow of goods and services, allowing for an examination of economic interactions and their environmental impacts, particularly in the context of sustainability metrics.

1. Input-output analysis helps to quantify the economic interdependencies between sectors, making it easier to identify how changes in one area can affect others.
2. This analysis can reveal the indirect environmental impacts of industries by showing how resource use and emissions flow through the economy.
3. It is often employed in policymaking to assess the implications of economic activities on sustainable development goals.
4. Input-output tables are used to represent the input-output relationships and can highlight both direct and indirect contributions to GDP and resource consumption.
5. The technique can be utilized to assess the circular economy by examining how waste from one sector can be repurposed as input for another sector.

Review Questions

• How does input-output analysis contribute to our understanding of the relationship between economic sectors?
  • Input-output analysis provides a clear framework for visualizing and quantifying the interconnections between various economic sectors. By mapping out how outputs from one sector serve as inputs for another, it enables a comprehensive understanding of economic dependencies. This interconnectedness can highlight potential vulnerabilities or strengths within the economy, allowing policymakers to make informed decisions regarding resource allocation and economic development strategies.
