Economists examine all types of markets, the means and strategies for profit maximization, industrial and labor organizations, the distribution of income and ownership rights, governmental activities and political and economic philosophies, and analyze how these and other factors influence the production of goods and services.

There are many types of economists, including business economists, labor economists, macroeconomists, public finance economists, behavioral economists and game theorists.
