Explain the demand function with the help of examples. Draw appropriate graphs where required.

The demand equation is the mathematical expression of the relationship between the quantity of a good demanded and those factors that affect the willingness and ability of a consumer to buy the good. For example, Qd = f(P; Prg, Y) is a demand equation where Qd is the quantity of a good demanded, P is the price of the good, Prg is the price of a related good, and Y is income; the function on the right side of the equation is called the demand function. The semi-colon in the list of arguments in the demand function means that the variables to the right are being held constant as we plot the demand curve in (quantity, price) space.

Case Study: A perfect competition

In 1997, over \$700 billion purchases were charged on credit cards, and this total is increasing at a rate of over 10 per cent a year. At first glance, the credit card market would seem to be a rather concentrated industry. Visa, MasterCard and American Express are the most familiar names, and over 60 per cent of all charges are made using one of these three cards.

Although Visa, Mastercard and American Express are the choices of the majority of consumers, these cards do not originate from just three firms. In fact, there are over six thousand enterprises (primarily banks and credit unions) in the US that offer charge cards to over 90 million credit card holders. One person's Visa card may have been issued by his company's credit union in Los Angeles, while a next door neighbour may have acquired hers from a Miami B

You : Why have you been interviewing people? Don't you have a human resource department? President : Yes, we do. However, the human resource department does not hire top management people. As soon as I took over, I found out that two of my vice presidents were retiring and we had no one to replace them. You : Have you hired anyone? President : Yes, I have, and that is part of the problem. I hired a person from the outside. As soon as the announcement was made, one of my department heads came in and resigned. She said she had wanted that job as vice president for eight years. She was angry because we had hired someone from outside. How was I supposed to know she wanted the job?
