Overview of Positive and Normative Economics

Positive Economics

Positive economics examines the economy's progress in a neutral manner, focusing on factual analyses related to the causes and effects of economic phenomena. It is grounded in objective and scientific explanations of how an economic system operates. The goal is to provide an unbiased understanding of economic issues without suggesting solutions or judgments.

Normative Economics

In contrast, normative economics suggests solutions to economic problems encountered by a country. It involves the economist’s personal opinions on issues, such as wealth distribution. For example, one economist might advocate for heavy taxation on the rich to equalize wealth distribution, while another may caution against such measures due to potential adverse effects, like a decrease in investment rates. This contrasts the subjective perspective of normative economics with the objective nature of positive economics.

Kinds of Positive Economics

Positive economics can be subdivided into two main categories:

Microeconomics

Microeconomics focuses on the behavior of individual units of an economic system, such as consumers, firms, and industries. It examines small parts of the economy rather than the overall economic picture. Key elements of microeconomics include:

  1. Theory of Price: Prof. Robbins states that human wants are unlimited, but resources are limited, leading to choices that must be made based on the price mechanism. The prices of goods are determined by the equilibrium of demand and supply.
  2. Theory of Consumer Behavior: This part studies how consumers use their limited resources to satisfy unlimited wants. It includes the analysis of factors influencing consumer decisions and concepts such as utility and elasticity of demand.
  3. Theory of Firm Behavior: In capitalist systems, firms determine their production quantities based on profit maximization. This theory explores how firms find the optimal combination of production factors and examines costs and revenues.
  4. Theory of Distribution of Wealth: This examines how the prices of production factors (land, labor, capital, organization) are determined, delving into theories like marginal productivity.

Macroeconomics

Macroeconomics deals with the economy as a whole, analyzing large-scale economic aggregates. Key areas of study include:

  1. National Income and Employment: It investigates national income levels, full employment, and the factors affecting national income stability.
  2. Trade Cycle Theory: This explores the cyclical nature of trade, including fluctuations in prices and income, identifying causes and proposing remedies.
  3. Money Theory: This includes the functions of money, value determination, and the roles of commercial and central banks in the economy.
  4. International Trade Theory: Discusses the significance and dynamics of international trade, benefits, drawbacks, and balance of payment theories.
  5. Public Finance Theory: Covers sources of government revenue, expenditure items, and government debt management.

Applied Economics

Applied economics utilizes insights from theoretical economics to address real-world economic problems. It involves implementing policies that aim to enhance living standards, increase employment rates, and boost national development, tailoring theoretical framework analyses to practical applications within a country’s economic context.
