According to Mankiw (2018), microeconomics is the study of how individuals and firms make decisions and interact in markets. It focuses on the behavior of individual agents, such as consumers and producers, and the determination of prices and quantities in specific markets.
Varian (2014) defines microeconomics as the study of individual economic units and their interactions in specific markets, aiming to understand the choices made by individuals and the implications of those choices for market outcomes
