Activity: The Magic of Markets – Trade Creates Wealth

Overview:

Trade is the voluntary exchange of goods and services. People engaging in trade must be willing to bear a cost (give up something). Therefore, we know that people will only participate voluntarily when they expect to gain from the exchange. If even one of the trading partners believes he cannot gain, the exchange will not take place.
