Five basic market structures in mikroeconomics

All of these videos are available online at http: This book reflects how I, personally, teach the Principles material to my students. If there are gaps in the content that you would like to see covered, let me know - in the past, I have been able to create material based on feedback from the YouTube audience. However, a student really should have good writing skills and some basic math skills to do well in an introductory Economics course.

But they also study the minute world of atoms and the tiny particles that comprise those atoms. Economists also look at two realms. There is big-picture macroeconomics, which is concerned with how the overall economy works.

It studies such things as employment, gross domestic product, and inflation—the stuff of news stories and government policy debates. Little-picture microeconomics is concerned with how supply and demand interact in individual markets for goods and services.

In macroeconomics, the subject is typically a nation—how all markets interact to generate big phenomena that economists call aggregate variables.

In the realm of microeconomics, the object of analysis is a single market—for example, whether price rises in the automobile or oil industries are driven by supply or demand changes. The government is a major object of analysis in macroeconomics—for example, studying the role it plays in contributing to overall economic growth or fighting inflation.

Macroeconomics often extends to the international sphere because domestic markets are linked to foreign markets through tradeinvestment, and capital flows.

But microeconomics can have an international component as well. Single markets often are not confined to single countries; the global market for petroleum is an obvious example. Economists commonly consider themselves microeconomists or macroeconomists. The American Economic Association recently introduced several new academic journals.

One is called Microeconomics. Another, appropriately, is titled Macroeconomics. It was not always this way. In fact, from the late 18th century until the Great Depression of the s, economics was economics—the study of how human societies organize the production, distribution, and consumption of goods and services.

The field began with the observations of the earliest economists, such as Adam Smith, the Scottish philosopher popularly credited with being the father of economics—although scholars were making economic observations long before Smith authored The Wealth of Nations in Smith and other early economic thinkers such as David Hume gave birth to the field at the onset of the Industrial Revolution.

Economists implicitly assumed that either markets were in equilibrium—such that prices would adjust to equalize supply and demand—or that in the event of a transient shock, such as a financial crisis or a famine, markets would quickly return to equilibrium.

In other words, economists believed that the study of individual markets would adequately explain the behavior of what we now call aggregate variables, such as unemployment and output. The severe and prolonged global collapse in economic activity that occurred during the Great Depression changed that.

It was not that economists were unaware that aggregate variables could be unstable. They studied business cycles—as economies regularly changed from a condition of rising output and employment to reduced or falling growth and rising unemployment, frequently punctuated by severe changes or economic crises.

Economists also studied money and its role in the economy. But the economics of the time could not explain the Great Depression. If Adam Smith is the father of economics, John Maynard Keynes is the founding father of macroeconomics.

Its main concern is the instability of aggregate variables. Whereas early economics concentrated on equilibrium in individual markets, Keynes introduced the simultaneous consideration of equilibrium in three interrelated sets of markets—for goods, labor, and finance.

His approach was taken up by other leading economists and developed rapidly into what is now known as macroeconomics.

Coexistence and complementarity Microeconomics is based on models of consumers or firms which economists call agents that make decisions about what to buy, sell, or produce—with the assumption that those decisions result in perfect market clearing demand equals supply and other ideal conditions.

Macroeconomics, on the other hand, began from observed divergences from what would have been anticipated results under the classical tradition.

Today the two fields coexist and complement each other. Microeconomics, in its examination of the behavior of individual consumers and firms, is divided into consumer demand theory, production theory also called the theory of the firmand related topics such as the nature of market competition, economic welfare, the role of imperfect information in economic outcomes, and at the most abstract, general equilibrium, which deals simultaneously with many markets.

Much economic analysis is microeconomic in nature. It concerns such issues as the effects of minimum wages, taxes, price supports, or monopoly on individual markets and is filled with concepts that are recognizable in the real world.

It has applications in trade, industrial organization and market structure, labor economics, public finance, and welfare economics.Mar 25,  · A monopoly is when one firm is the only company in the market, and has enormous control over the market, and thus is highly profitable, though it is still possible for a monopolist to hurt their profits by charging too much.

Oligopoly, in which a market is run by a small number of firms that together control the majority of the market share.

The interconnected characteristics of a market, such as the number and relative strength of buyers and sellers and degree of collusion among them, level and forms of competition, extent of product differentiation, and ease of entry into and exit from the market.

Four basic types of market structure are (1) Perfect competition: many buyers and sellers, . Lecture 6: Market Structure – Perfect Competition I.

Concepts of Competition Whether a firm can be regarded as competitive depends on several factors, the most important of which are: • The number of firms in the industry.

As the number of firms increases, the effect of any one firm on the price and quantity in the market declines.
