The position prices can fall to stimulate demand. and size of the market are crucial If the price of the computer falls to in price determination, as is time. The price at which producers are happy to sell is not just influenced by the costs of production. For instance, consider a market stall selling fresh produce. The farmer arrives having already paid for the costs of production, buying the seeds, the labor involved in planting and harvesting the crop, and his transport to the market. He knows that to make a profit, he must sell each apple for $1.20. Fruit sellers may have to throw away any unsold apples at the end of the day. The urgency to sell in time is a major factor in determining the price at which to sell perishable goods.

INDUSTRIAL AND ECONOMIC REVOLUTIONS 113 Producers of goods such as Coca- Cola may influence demand through advertising that promotes the product and the brand. As demand rises, the price of the product may also rise. Therefore, at the start of the day, with an excess of apples that are of the gold is under no time he decides to market his apples at likely to rot before his next chance pressure to sell.

Economists call Marshall’s work “partial equilibrium” analysis because it shows how a single market reaches equilibrium or balance through the forces of supply and demand. However, an economy is made up of many different interacting markets. The question of how all these can come together in a state of “general equilibrium” is a complex problem that was analyzed by Léon Walras (p.120) in the 19th century. ■

Walras began to construct mathematical models to describe the relationship between supply and demand. These revealed that as price escalates, demand falls and supply climbs. Where demand and supply match, the market is in a state of equilibrium, or balance. This reflected the same kind of simple balancing forces that were evident in Newton’s laws of motion. General equilibrium To illustrate this equilibrium, imagine that today the current market price of mobile phones is $20. In a local market store owners have 100 phones for which they want $20. If 100 buyers visit the market, each willing to pay $20, the market for cheap mobiles is in equilibrium because the supply ❯❯

S. Mill’s and David Ricardo’s theories of competition. AFTER 1921 Frank Knight develops the notion of perfect competition. 1948 Friedrich Hayek’s Individualism and Economic Order attacks Marshall’s view of perfect competition. I n the late 18th century Adam Smith (p.61) wrote about the impact of competition on firms’ abilities to set prices and make profits above a “natural” level. However, there was no formal analysis of the situation until British economist Alfred Marshall (p.110) published Economic Principles in 1890. The ideas in Marshall’s model remain a key part of mainstream economic theory, although the theory has been criticized as not representing the true nature of competition. Perfect competition The model that Marshall developed to explain why firms were unable to set their own prices has become known as “perfect competition.”
