Which is studied by economist to understand how resources are used?

Economists study microeconomics and macroeconomics to understand how resources are allocated and utilized. Microeconomics focuses on individual consumers and firms, analyzing their decision-making processes and resource allocation at a smaller scale. Macroeconomics examines the overall economy, including national output, employment, and inflation, to understand resource distribution on a larger scale. Together, these fields help economists assess efficiency, productivity, and the impact of policies on resource use.
