The powerful concept of supply and demand in economic history

The Market Mechanism All societies necessarily make economic choices. Society needs to make choices about, what should be produced, how should those goods and services be produced, and whom is allowed to consumes those goods and services. For conventional economics the market by way of the operation of supply and demand answer these questions. Under conditions of competition, where no one has the power to influence or set price, the market everyone, producers and consumers together determines the price of a product, and the price determines what is produced, and who can afford to consume it.

In both markets firms are price-takers. The price is set at the market level through the interaction of supply and demand. The firms can sell as much of the product as they want at the set price since they are price-takers.

Resource demand[ edit ] The buyers in the factor markets are the firms that produce the final goods for the products markets. Each firm must decide how much labor to hire to maximize its profits.

The decision is made through marginal analysis. The firm will hire a worker if the marginal benefits exceed the marginal costs. The curve shows the relationship between the quantity demanded and the wage rate holding the marginal product of labor and the output price constant.

The units of labor are on the horizontal axis and the price of labor, w the wage rate on the vertical axis. The price of labor and the quantity of labor demanded are inversely related. If the price of labor goes up the quantity of labor demanded goes down. Factors that can affect a shift of the curve are changes in 1 the price of the final product or output price 2 the productivity of the resource 3 the number of buyers of the resource and 4 the price of related resources.

Changes in productivity - Productivity changes affect the resource demand in several ways. The quantity of other resources can affect productivity.

Factor market - Wikipedia

The more machines labor has to work with the greater the marginal product of labor which will cause the resource demand curve to shift out. The quality of the resource is an important factor in determining the value of labor as a resource.

For example, a highly educated and experienced labor force is generally more productive.

Changes in the number of buyers of the resource - As with any market, additional buyers will cause the demand curve to shift out. A change in the price of a related resource will affect the demand for labor.

For example, automobiles can be assembled with varying combinations of labor and machinery. If the price of machinery falls firms will tend to substitute machines for labor and the demand for labor will fall. If labor and machinery are used as complementary resources and the price of machinery falls then more machinery will be bought and more workers will be needed to run the new machines, causing the labor demand curve to shift out.

Price elasticity of resource demand PERD [ edit ] As with the product market, a manager must not only know the direction of a change in demand but the magnitude of the change.

PERD for a resource depends on: If the price of Coca Cola rises, this will induce a substantial decline in the quantity of Coca Cola demanded. The decline in quantity demanded for Coca Cola will reduce the demand for all inputs used in the production of Coke.

The importance of factor in production process [17] - The more important the factor, the less elastic is the PERD. The more time to adjust the higher the PERD.

The market supply curve is the summation of individual supply curves. The resource supply curve is similar to the products supply curve. The market supply curve is the summation of individual supply curves and is upward sloping. It shows the relationship between the resource price and the quantity of the resource that resource providers are willing to sell and able to sell.

Factors that will cause a shift in the factor supply curve include changes in tastes, number of suppliers and the prices of related resources.

Price elasticity of resource supply[ edit ] The price elasticity of resource supply PERS equals the percentage change in the quantity of resource supplied induced by a percent change in price of the resource.

Monopolist factor demand[ edit ] If the producer of a good is a monopolythe factor demand curve is also the MRPL curve. The curve is downward sloping because both the marginal product of labor and marginal revenue fall as output increases. This contrasts with a competitive firm, for which marginal revenue is constant and the downward slope is due solely to the decreasing marginal product of labor.

Supply and Demand

The implications are that a monopoly or any firm operating under imperfect market conditions will produce less and hire less labor than a perfectly competitive firm at a given price. Monopsony and oligopsony[ edit ] Main articles: Monopsony and Oligopsony If the firm is the only buyer in a particular factor market, then it is a monopsonist.

If the firm is one of several purchasers, then it is instead an and demand, and other economic indicators. Discover how individuals, business leaders, and even the leaders sometimes very difficult ones.

Supply and demand is a powerful thing; it can force you to go without, pay more than you want to, or force you to look elsewhere for the things you want. History/social studies. In economics, a factor market is a market where factors of production are bought and sold, such as the labor market, the physical capital market, the market for raw materials, and the market for management or entrepreneurial resources.

Supply and demand analysis is an extremely powerful economic tool, however it's often misunderstood. The first misconception I cover is the idea of "The Law Of Supply and Demand." This is a very popular statement, however it's not entirely true.

Economics, social science that seeks to analyze and describe the production, distribution, and consumption of wealth. In the 19th century economics was the hobby of gentlemen of leisure and the vocation of a few academics; economists wrote about economic policy but were rarely consulted by legislators before decisions were made.

Today there is hardly a government, international agency, or. Statistical Process Control. Statistical Process Control, or SPC, is the method developed by Shewhart in It exists to monitor or regulate a process to guarantee it functions to its highest capabilities. While public policy should not compel individual moral beliefs or practices, and economic policy should not be used to enforce personal ethics, such policy perhaps should at least be consistent with values such as compassion which, like the justifications for public policy themselves, are based on the manner in which we interact with others.
