Microeconomics examines the decisions of economic agents like households and businesses, analyzes individual markets, and calculates welfare in various market structures. It addresses questions like budget optimization for households, maximizing output for businesses, and calculating consumer and producer surplus.
Microeconomics, along with macroeconomics, is part of economics. While microeconomics focuses on individual markets and economic agents, macroeconomics looks at the overall economy of a country. A key assumption in microeconomic models is the 'homo oeconomicus,' who always seeks to maximize their utility.
Household theory deals with making choices between different bundles of goods with a fixed budget to maximize utility. An example is deciding how to spend a shared household budget, whether on appliances or food. The utility derived from different combinations is expressed through a utility function.
Production theory concerns businesses and how they combine input factors to achieve maximum output. For instance, a farmer decides on the number of machines and employees needed to harvest crops efficiently. Through their production function, they aim to maximize profit or minimize costs.
Price theory focuses on determining the optimal price for products based on market conditions, such as competition. Whether a seller is a sole provider or one among many competitors influences their pricing power. The goal is to set the best price depending on the market form.
