Input-output analysis is a behavioral economics strategy used to understand the impact of one business sector on others within the same economy. Developed by Wassily Leontief, the analysis can identify the impact of a company’s actions on other companies and can be used to project the impact of changes on interconnected industries. It can also help to avoid economic crises.

An input-output analysis is a strategy within behavioral economics that seeks to understand and qualify the impact of activity in one business sector on other sectors within the same general economy. This approach can be used to assess economic connections within a local economy, a national economy, or even the global economy. Such an analysis can also be used to identify the impact of a company’s actions on other companies operating in the same industry.

The general concept for an input-output analysis was developed by Wassily Leontief, who later received the Nobel Prize in Economic Sciences for his work in defining the concept and developing the model that is still used today to illustrate the resulting results. of the analysis. . By demonstrating how various industries depend on other industries to produce the raw materials they need, it is possible to use a simple matrix to demonstrate how production levels in one industry can have a positive or negative effect on a connected industry. At the same time, input-output analysis can show how those changes within an industry or group of industries can support growth within an economy or undermine the stability of that economy, triggering an economic crisis.

A classic example of an input-output analysis begins with the production of goods in one industry that are needed to support the production of goods in another industry. For example, coal must be mined to provide materials for the production of steel. If adverse conditions weaken the coal industry to the point that mining operations are reduced, the steel industry must find some way to compensate for that reduced production to avoid a reduction in steel creation. Since the actual tonnage of coal entering the steel industry results in less tonnage of steel material, input-output analysis allows for the difference and makes it easy to determine what effect the change ultimately has. in coal production. has in steel production.

Economists and national governments often use the input-output analysis model to project the impact of some change on industries that are interconnected in some way. By doing so, it is possible to determine whether those changes will create short-term economic effects that are undesirable, and even whether the changes could trigger a chain of events that would lead to a recession or other type of economic crisis. By using input-output analysis to accurately project how changes will affect the economy, it is possible to use government-based initiatives to support those changes and subsequent events, or find ways to minimize the impact of those changes and avoid some kind of of economic recession.
