The scope of managerial economics falls into two broad parts: microeconomics for the problems inside the firm, and macroeconomics for the conditions outside it.
Microeconomics for solving operational problems
Managers use microeconomic principles to handle internal matters such as production, sales, distribution, capital, pricing, profit and the workforce. The main theories they draw on are these.
- Production theory: to get high output from limited resources, the firm studies its production decisions: how much capital and labour it needs, its capacity, its processes and techniques, and its cost and quality.
- Investment theory: the firm plans its capital spending carefully so that resources are used well and earn good returns.
- Demand theory: to keep customers satisfied, managers study what consumers need and how they respond to the firm's products and services.
- Market structure and pricing theory: the firm decides its prices competitively, taking into account production cost, market demand and marketing cost.
- Profit management: since profit is a central aim, the firm keeps a close watch on both cost and revenue.
Macroeconomics for handling the external environment
A business also faces challenges it cannot control. Macroeconomic thinking, often organised through a PESTEL analysis, helps the manager read that environment.
- Political (P): the government plays a large part in a firm's progress, so managers study how the style of governance, political unrest and foreign collaboration affect private companies.
- Economic (E): profitability depends heavily on government policy, tax changes, GDP growth and the country's economic stability.
- Social (S): society's values, beliefs and attitudes, consumer awareness, employment conditions, literacy and trade unions all shape a business.
- Technological (T): technology improves how goods and services are produced and distributed.
- Environmental (E): as concern for the environment grows, firms are pressed to adopt sustainable practices: cutting pollution, managing waste and conserving water and other natural resources.
- Legal (L): businesses must work within the law, including consumer rights, labour laws, health and safety rules, labelling rules and advertising guidelines.
