What makes the prices of oil and gasoline double in just one year? Will these prices keep on rising? Are the oil com- panies taking advantage of people? This chapter enables you to answer these and similar questions about prices—prices that rise, prices that fall, and prices that fluctuate. You already know that economics is about the choices peo- ple make to cope with scarcity and how those choices respond to incentives. Prices act as incentives. You’re going to see how people respond to prices and how prices get deter- mined by demand and supply. The demand and supply model that you study in this chapter is the main tool of economics. It helps us to answer the big economic question: What, how, and for whom goods and services are produced? At the end of the chapter, in Reading Between the Lines , we’ll apply the model to market for gasoline and explain why the price increased so sharply in 2008.

Let’s begin our study of demand and supply, starting with demand. 54 CHAPTER 3 Demand and Supply Markets and Prices When you need a new pair of running shoes, want a bagel and a latte, plan to upgrade your cell phone, or need to fly home for Thanksgiving, you must find a place where people sell those items or offer those ser- vices. The place in which you find them is a market. You learned in Chapter 2 (p. 44) that a market is any arrangement that enables buyers and sellers to get information and to do business with each other. A market has two sides: buyers and sellers. There are markets for goods such as apples and hiking boots, for services such as haircuts and tennis lessons, for resources such as computer programmers and earth- movers, and for other manufactured inputs such as memory chips and auto parts. There are also markets for money such as Japanese yen and for financial securities such as Yahoo! stock. Only our imagination limits what can be traded in markets. Some markets are physical places where buyers and sellers meet and where an auctioneer or a broker helps to determine the prices. Examples of this type of market are the New York Stock Exchange and the wholesale fish, meat, and produce markets. Some markets are groups of people spread around the world who never meet and know little about each other but are connected through the Internet or by tele- phone and fax. Examples are the e-commerce markets and the currency markets. But most markets are unorganized collections of buyers and sellers. You do most of your trading in this type of market. An example is the market for basketball shoes. The buyers in this $3 billion-a-year market are the 45 million Americans who play bas- ketball (or who want to make a fashion statement). The sellers are the tens of thousands of retail sports equipment and footwear stores. Each buyer can visit several different stores, and each seller knows that the buyer has a choice of stores.
