What is Market Price?

In finance, the term market price, or market value, refers to the most recent price at which a security transaction took place, if it was completed on an exchange. If the transaction took place over-the-counter, with brokers and dealers negotiating directly with each other, market price refers to the most current bid, the price requested by the broker, and the most current ask, the price demanded by the dealer. As an economic concept, market price is the price at which a good or service is offered at in the marketplace. This price is reached when market supply and market demand meet. Alfred Marshall, an influential English economist, developed the supply and demand model to explain how human behavior determined market price. Supply is the service or good that producers are willing to provide at a given price. Demand is the value of a service or good that purchasers are willing to buy at a given price. There is an inverse relationship between price and supply, and a direct relationship between price and demand. On a typical supply and demand graph, the X-axis shows quantity and the Y-axis shows price. The supply curve slopes upward while the demand curve slopes downwards. The point of intersection between the two curves is the market price, also known as the equilibrium point. Various factors can shift the supply or demand curve significantly affecting the equilibrium price. For example, change in weather can affect the supply of certain goods while the change in consumer preference can greatly change demand. This supply and demand theory regarding market price, while popular, has been criticized as being too simplistic. It can be argued that a good or service may already have a price before reaching the marketplace. Moreover, buyers are not always considered by producers when creating a commodity. Another contradiction to Marshall’s theory comes from Keynesian economics, named after the renowned economist John Keynes. He noted that prices could become “sticky” by not responding to fluctuations in neither demand nor supply. This is especially likely to occur when prices are decreasing. A noted example of such as situation is the Boston housing market in the 1990s. Buyers and sellers could not agree on a market price as the market dried. Other deterrents to the natural laws of supply and demand are monopoly and oligopoly. The sole or a limited number of providers of a certain commodity has the power to dictate the market price. Similarly, in a monopsony, situations where there are many sellers and one buyer, the buyer is able to dictate the price.
