Ví dụ: 2 công ty cùng bán một sản phẩm có giá 10 đồng, công ty A bỏ chi phí 6đ/ chiếc - lợi nhuận 4₫/chiếc, công ty B bỏ chi phí 9đ/ chiếc - Lợi nhuận 1₫/chiếc.  Giả sử chi phí và quy mô giữ nguyên, do nhu cầu tăng nên giá sản phẩm tăng lên 12₫, lúc này công ty A tăng lợi nhuận từ 4₫ lên 6₫ => lợi nhuận tăng 50%, công ty B tăng lợi nhuận từ 1₫ lên 3₫ => lợi nhuận tăng 300%.
