Lisa Walker spent a year in Sierra Leone, West Africa, as a Peace Corps volunteer, and she kept a diary of her experiences. One thing she wrote about was what happened when the government-imposed price controls on many common items. “For the past 5 days,” she wrote, “nobody has sold cigarettes, kerosene, Maggi (bouillon) cubes, or rice here . . . This is the result of the government’s new order. The government says the Maggi cubes have to be sold for 30 cents, but the sellers bought them for 50 cents, so when military men enter the village to enforce the government price, those with Maggis hide them. It is the same story for cigarettes and kerosene. The rice supplies are hidden because of government prices. Unless one is willing to pay an outrageous price, it is impossible to buy rice in the marketplace. The only way to get rice legally is to buy it from the government. This means standing in long lines for many hours to get a rationed amount. I don’t know how Sierra Leoneans are managing or how long this artificial shortage will last.” How would you graphically illustrate the market for rice in Sierra Leone in the presence of price controls?
