Substituutio, in the context of economics, refers to the concept where one good or service can be used in place of another to satisfy a similar need or want. These are known as substitute goods. For example, coffee and tea are often considered substitutes. If the price of coffee increases significantly, consumers might switch to drinking more tea, thus increasing the demand for tea. Conversely, if the price of tea falls, consumers might buy less coffee and opt for tea instead.

The availability and closeness of substitutes are crucial factors in determining the price elasticity of demand for a product. Goods with many readily available substitutes tend to have a more elastic demand, meaning that a price change will lead to a proportionally larger change in quantity demanded. This is because consumers have numerous alternatives to choose from. Products with few or no close substitutes, such as essential medicines or unique luxury items, typically have a more inelastic demand.

In a broader economic sense, substitutability can also apply to factors of production. For instance, businesses might substitute labor for capital or vice versa, depending on their relative prices and the technological possibilities available. If wages increase substantially, a firm might invest in more automation to replace human workers. The degree to which one factor can be substituted for another is a key consideration in production theory and the analysis of market structures.
