Although it is confirmed that the demand curve arises naturally from the theory of consumer choice, the derivation of the demand curve itself is not a theory that proposes consumer behavior.

In general, when an item** goes up, people buy less. Chapter 4 refers to this normal behavior as the law of demand. This pattern manifests itself in the demand curve sloping to the lower right.

However, as far as economic theory is concerned, the demand curve also sometimes slopes to the upper right. In other words, consumers sometimes defy the law of demand and buy more when one item rises. To illustrate how this can happen, look at Figure 21-12.

In this example, the consumer buys two items – meat and potatoes. Initially, the consumer budget constraint line was a straight line from A to B. The best advantage is c.

When the potato ** rises, the budget constraint line moves inward and is now a straight line from A to D. Now the best thing is e. It is important to note that the rise in potatoes has led consumers to buy more potatoes.
