The most basic concern of economists is to allocate scarce resources in order to satisfy human wants. This means that economists study how to best use limited resources, such as time, money, and natural resources, to meet people's needs and desires. They look at how to distribute goods and services, as well as how to produce and consume them in the most efficient and effective way possible. Ultimately, the goal of economics is to improve the standard of living for all members of society by optimizing the use of available resources.
