Delta (Economics)

In economics, "delta" (usually represented by the Greek letter Δ) signifies a change or difference in a particular variable. For example, Δ price refers to the change in price over a period, and Δ quantity refers to the change in the quantity of a good sold. It helps economists analyze how small shifts in one factor can impact others, such as how a price increase might affect demand. Essentially, delta measures the variation or movement in economic data, providing insight into trends and relationships within markets or behaviors.
