As consumers, there is a wide variety of products that we buy daily to satisfy our wants and needs, but we don’t give much thought to how those products coincide with one another or if they even do. Some products that we can either be labeled as a substitute product or as a complimenting product. Various products that we purchase can automatically up the demand for another product ultimately making it a compliment product. If we were to use a graph to see the results of complementing products we would quickly learn that if there is an increase in products A and the complimenting product B would follow suite thereafter with an increase. If we was to purchase a vacuum cleaner that required a bag, we would also need to purchase the vacuum bags. These two products complement each other as you need both of the vacuum and bag for the merchandise to work, yet both are sold separately. Some people may purchase a muffin and coffee and consider both food items as a complement to each other. A larger scale example would be automobiles. When we purchase an automobile, we are under the understanding that we will have to purchase some type of fuel for this product. Most automobiles do not hold an unlimited amount of gas making it necessary to purchase fuel. The rise and demand for automobiles have also increased the demand for gasoline. If we consider a world with no automobiles where we all rode on bicycles there would not be a high demand for gasoline. Cars and gasoline would be considered to complement each other without cars there would not be a high demand for gasoline and without gasoline we wouldn’t need cars. Cars and gasoline do, in fact, complement each other, but also for many consumers both products could be considered an inelastic demand. There are indeed substitute options for both, but can be too expensive for the average consumer and most generally be out of reach.
