Macroeconomics is the study of the performance, structure, behavior and decision-making of an economy as a whole.
Learning Objective: Define macroeconomics and identify the main users of macroeconomics.
Macroeconomics is the study of the performance, structure, behavior and decision-making of an economy as a whole. Macroeconomists focus on the national, regional, and global scales. For most macroeconomists, the purpose of this discipline is to maximize national income and provide national economic growth. Economists hope that this growth translates to increased utility and an improved standard of living for the economy's participants. While differences among the objectives of national and international entities exist, most follow the ones detailed below:
Macroeconomics studies the performance of national or global economies and the interaction of certain entities at this level.
To achieve these goals, macroeconomists develop models that explain the relationship among factors that include national income, output, consumption, unemployment, inflation, savings, investment and international trade. These models rely on aggregated economic indicators such as gross domestic product (GDP), unemployment, and price indices.
On the national level, macroeconomists hope their models address two key areas of research:
Microeconomics deals with the economic interactions of a specific person, a single entity or a company; it is the study of markets.
Learning Objectives: Define Microeconomics, Identify the main users of microeconomics.
Microeconomics deals with the economic interactions of a specific person, a single entity, or a company. These interactions, which mainly are buying and selling goods, occur in markets. Therefore, microeconomics is the study of markets. The two key elements of this economic science are the interaction between supply and demand and scarcity of goods.
Supply and Demand Graph: Microeconomics is based on the study of supply and demand at the personal and corporate level.
One of the major goals of microeconomics is to analyze the market and determine the price for goods and services that best allocates limited resources among the different alternative uses. This study is especially important for producers as they decide what to manufacture and the appropriate selling price. Microeconomics assumes businesses are rational and produce goods that maximize their profit. If each firm takes the most profitable path, the principles of microeconomics state that the market’s limited resources will be allocated efficiently.
The science of microeconomics covers a variety of specialized areas of study including:
Microeconomics focuses on individual markets, while macroeconomics focuses on whole economies.
Learning Objectives: Recognize questions addressed by microeconomics and macroeconomics.
Stemming from Adam Smith’s seminal book, The Wealth of Nations, microeconomic and macroeconomics both focus on the allocation of scarce resources. Both disciplines study how the demand for certain resources interacts with the ability to supply that good to determine how to best distribute and allocate that resource among many consumers. Both disciplines are about maximization: microeconomics is about maximizing profit for firms, and surplus for consumers and producers, while macroeconomics is about maximizing national income and growth.
Adam Smith, Founding Father of Economics: Adam Smith’s book, Wealth of Nations, was the basis of both microeconomic and macroeconomic study.
The main difference between microeconomics and macroeconomics is scale. Microeconomics studies the behavior of individual households and firms in making decisions on the allocation of limited resources. Another way to phrase this is to say that microeconomics is the study of markets.
In contrast macroeconomics involves the sum total of economic activity, dealing with the issues such as growth, inflation, and unemployment. Macroeconomics is the study of economies on the national, regional or global scale.
This key difference alters how the two approach economic situations. Microeconomics does consider how macroeconomic forces impact the world, but it focuses on how those forces impact individual firms and industries. While macroeconomists study the economy as a whole, microeconomists are concerned with specific firms or industries.
Many economic events are of great interest to both microeconomist and macroeconomists, though they differ in how they analyze those events. A shift in tax policy would interest economists in both disciplines. A microeconomist might focus on how the tax might shift supply in a specific market or influence a firm’s decision making, while the macroeconomist will consider whether the tax will translate into an improved standard of living for all of the economy’s participants.
