Economists are experts who study the relationship between the resources available in society and the level of output produced. They try to discover how people allocate scarce resources to insatiable alternatives to provide commodities and services in the market. They collect data and formulate theories to help decision-makers develop informed policies. Economists study both macro and microeconomics. Inflation, unemployment, economic growth, and net exports are some of the fields that require economic expertise. Economists do not eliminate the scarcity of resources (b); instead, they assist producers and other economic agents in allocating resources efficiently by considering factors such as opportunity cost and utility maximization.
