PRINCIPLES OF ECONOMICS
INTRODUCTION TO THE PRINCIPLES OF ECONOMIC
Political Economy or Economics is a study of mankind in the ordinary business of life; it examines that part of individual and social action which is most closely connected with the attainment and with the use of the material requisites of wellbeing.
1. Principles of Economics
The principles of economics provide a framework for understanding how economic agents make decisions and how markets function. Here are some key principles:
-
Scarcity: Resources are limited, which forces individuals and societies to make choices about how to allocate them.
-
Opportunity Cost: The true cost of something is what you give up to get it. This principle emphasizes the trade-offs involved in any decision.
-
Supply and Demand: Prices are determined by the relationship between supply (how much of a good is available) and demand (how much of it consumers want). This interaction helps establish market equilibrium.
-
Marginal Thinking: Decisions are made at the margin, meaning individuals weigh the additional benefits of an action against its additional costs.
-
Incentives Matter: Economic agents respond to incentives. Changes in prices, taxes, or regulations can motivate different behaviors.
-
Trade Can Make Everyone Better Off: Specialization and trade allow individuals and countries to focus on what they do best, increasing overall economic efficiency and wealth.
-
Markets Are Usually a Good Way to Organize Economic Activity: In a market economy, the decentralized decisions of many households and firms lead to efficient allocation of resources.
-
Government Can Sometimes Improve Market Outcomes: Market failures, such as externalities or public goods, may require government intervention to enhance efficiency or equity.
-
Economic Growth Is Important: Long-term economic growth improves living standards and is essential for reducing poverty.
-
Inflation and Unemployment Are Related: The Phillips curve illustrates the trade-off between inflation and unemployment in the short run, suggesting that reducing inflation may lead to higher unemployment and vice versa.
