Economists study the world’s resources and how they are distributed to provide the services we use or the things we buy. They perform studies to collect data, and analyze it to find economic trends that they can then use to help change economic policies. Many economists work for the government or as consultants. Economists working for companies, for example, might help predict the supply and demand for a product, which can help a company decide how to conduct their business. Many economist jobs require a master’s or a doctorate degree.
