Input-output analysis

Definition

Input-output analysis is a quantitative economic technique that studies the interdependencies between different sectors of an economy by examining how the output of one sector is an input to another. This method helps to understand the flow of goods and services within an economy, illustrating how agricultural production links to other sectors like manufacturing and services. By analyzing these relationships, input-output analysis can provide insights into economic development and the role of agriculture in overall economic growth.
