Microeconomics: Understanding and What is Microeconomics?

Microeconomics is a branch of economics and social science that delves into the consequences of decisions and motivations, market analysis, consumer, household, and enterprise behavior, all underpinned by mathematical models.

It aims to uncover why different goods possess distinct prices and how businesses and individuals engage in trade, reaping profits from these exchanges.

Microeconomics primarily focuses on the dynamics of supply and demand for goods and services, as well as the factors influencing prices in specific markets, particularly those where goods are bought and sold. It provides a more in-depth perspective and detailed insights compared to macroeconomics. The essence of microeconomics lies in predicting human responses to alterations in prices, production methods, and incentives.

History of Microeconomics

Perhaps one of the earliest texts to unravel the intricate web of consumer decision-making was penned by the Swiss mathematician Nicolas Bernoulli (1695-1726).

In the mid-18th century, Adam Smith’s theory of “laissez-faire” or non-intervention became the dominant economic ideology, championing free markets and capitalism. Smith’s economic philosophy reigned for two centuries until the early 20th century when Alfred Marshall (1842-1924), an economist from London, revolutionized economic thought. In his book “Principles of Economics,” Marshall formalized essential concepts like consumer utility, demand curves, and price elasticity of demand.

John Maynard Keynes (1883-1946), who had been developing his groundbreaking ideas about government’s role in managing the economy since the 1930s, emerged as the most influential economist of the 20th century.

Just as Keynes’ ideas left a profound mark on the global economy, Marshall’s contributions also significantly influenced financial discourse. The examination of individual economic units became an integral facet of economic studies.

In the 1950 s, Herbert Alexander Simon introduced his satisficing theory, which posits that when consumers discover goods or services that meet their needs and are sufficiently desirable, the decision-making process comes to an end.

Difference between Micro and Macroeconomics

Do you grasp the distinction between microeconomics and macroeconomics based on the definitions provided earlier? While microeconomics centers on firms and individuals, macroeconomics explores the entire spectrum of economic activities.

Microeconomics encompasses subjects such as consumer behavior, producer behavior, and the mechanisms for setting prices in various markets. In contrast, macroeconomics scrutinizes and assesses shifts in economic indicators like national income, employment levels, and the general price level.

Generally, macroeconomics can be more intricate, as it deals with relations among elements on such a large scale that not everyone may easily comprehend them. Concepts like national income and the general price level fall into the realm of macroeconomics. Microeconomics is grounded in models of consumer and firm decisions in buying and selling, reacting to market dynamics, whereas macroeconomics originated from observations of disparities between predictions and real-world outcomes.

Objectives of Microeconomics

One of the fundamental objectives of microeconomics is to investigate markets and establish relative monetary relationships for goods and services.

It also delves into instances of market failure, where the market fails to yield the desired and suitable outcomes, and it presents theories for fostering competitive markets.

Supply and demand theory typically assumes perfect competition, implying a market with numerous buyers and sellers, none of whom can exert influence over prices.

However, in reality, this assumption is problematic as many buyers and sellers can indeed influence prices. Consequently, crafting supply and demand models often necessitates intricate analysis to accurately reflect real-world scenarios.

The Application of Microeconomics

Microeconomics elucidates the expected outcomes under varying circumstances. For instance, if the price of mobile phones rises, consumers’ willingness to purchase them decreases, or in the event of a copper mine collapsing in California, global copper prices surge.

Microeconomics assists managers in comprehending that a decline in sales can lead to a corresponding decrease in the value of their company’s stock. These insights offer individuals, governments, and investors a framework for more profitable production, sales, or trading decisions.

Important Fields in Microeconomics

Microeconomics can be subdivided into several key fields, each offering unique insights into economic behavior and decision-making. These areas are:

1. Establishing General Equilibrium: This field focuses on understanding how various economic agents, such as consumers and firms, interact to reach a state of equilibrium in markets. It explores the dynamics of supply and demand, and how prices and quantities adjust to achieve balance.

2. Choice under Uncertainty: Microeconomics delves into the realm of decision-making in uncertain circumstances. It examines how individuals and firms make choices when facing risk and uncertainty, often involving probabilistic outcomes.

3. Game Theory: Game theory is a crucial aspect of microeconomics, which investigates strategic interactions among rational actors. It is used to analyze competitive situations, cooperation, and conflicts, offering insights into decision-making in various scenarios.

4. Elasticity of Supply and Demand: This field concerns the responsiveness of supply and demand to price changes. Understanding elasticity is essential in assessing how changes in price affect consumer and producer behavior within the market system.

Areas Related to Microeconomics

Microeconomics provides valuable insights into a wide range of areas:

Price Changes and Consumer Behavior:

When a producer raises the price of a good, microeconomics helps us predict that consumers are likely to purchase less of that good. It plays a pivotal role in analyzing how changes in price impact consumer choices.

Supply and Demand Dynamics:

In situations where supply is limited, microeconomics helps investors and market participants evaluate the associated risks and the potential rewards of taking those risks. It offers a perspective on how future events may unfold in such scenarios.

Macroeconomics and Competitive Markets:

Microeconomics is closely linked to macroeconomics, particularly in understanding how industries aim to enter and thrive in competitive markets. It underpins strategies and decisions in the broader economic landscape.

Political Influence and Institutions:

In the field of politics, microeconomics is employed to assess the role of institutions and political parties in shaping political outcomes. It aids in understanding the economic factors that influence political decisions.

Legal Institutions and Efficiency:

Legal institutions also benefit from microeconomic analysis, particularly in examining the efficiency of competitive legal systems. It helps evaluate the effectiveness of legal frameworks and their impact on economic activities.

Public Affairs and Fiscal Policies:

Microeconomics plays a pivotal role in determining tax and spending policies essential for a country’s economy in public affairs. It assists in making informed decisions about economic policies that promote growth and stability.

Purpose and Benefit of Microeconomics

In general, the emergence of microeconomics can be attributed to its successful response to two fundamental questions:

Resource Allocation for Individuals: How does an individual allocate their limited resources, such as their budget and time, among various goods and services to achieve their goal, typically assumed to be the maximization of utility?

Resource Allocation for Firms: How does a company utilize its finite resources, like the funds allocated for production, to employ factors of production effectively, aiming to achieve maximum production or profit?

The Utility of Microeconomics

The primary objective of microeconomics is not to predict market outcomes but to explain what one should anticipate when specific conditions change.

It directs its attention to the dynamics of supply and demand for goods and services, as well as the determination of prices in particular markets, predominantly those where goods are bought and sold.

One of the key purposes of microeconomics is to scrutinize markets and establish the relative monetary relationships between goods and services.

For instance, microeconomics provides insights into the fact that if a car manufacturer raises the price of its vehicles, consumers are likely to exhibit reduced willingness to purchase cars.

Similarly, if a significant copper mine in South Africa experiences a collapse, microeconomics tells us to expect a rise in copper prices due to the limited nature of natural resources. Microeconomics offers the capability to demonstrate to an investor why a company’s stock might decline if consumers reduce their purchases of its products.

Methods of Microeconomics

In 1874, Leon Walras introduced the theory of general equilibrium in his work “Elements of Pure Economics.” Sixteen years later, Alfred Marshall presented the theory of partial equilibrium in his book “Principles of Economics.” These theories form the foundational principles of most contemporary studies in microeconomics. These methods strive to depict human behavior using a mathematical operational language, enabling economists to diagnose human behavior through testable mathematical models. These two methods are integral to the framework of neoclassical economics.

Within neoclassical economics, quantifiable hypotheses regarding economic events must be formulated, with empirical evidence used to determine the most accurate hypotheses. Unlike physicists and biologists, economists cannot conduct repeatable experiments. Consequently, neoclassical economists simplify their assumptions regarding the market.

These simplifications might encompass presumptions of complete knowledge, an infinite number of sellers and buyers, identical goods, or the assumption of constant variable relationships to achieve a solution.

The effectiveness of microeconomics is evaluated based on the extent to which real-world markets conform to the principles suggested by these models.

Advantages of Studying Microeconomics

A little reflection and study of microeconomics can offer several advantages.

It enables individuals to comprehend how people’s decisions and behaviors impact the supply of services, the demand for goods, and the prices paid by consumers.

These prices, in turn, determine the quantity of goods demanded by consumers and the quantity of goods supplied by companies. Additionally, microeconomics explores how households make decisions regarding their purchases and savings.

Prerequisites for Learning Microeconomics

The prerequisites for learning microeconomics include a familiarity with and a reasonable mastery of mathematical sciences and economics.

This implies that individuals interested in studying this discipline should have some knowledge of algebra, optimization, and probability in mathematics, along with a basic understanding of economic principles.

Important Goals of Microeconomics

Microeconomics has numerous important goals. Its primary objective is to examine market conditions and establish relative monetary relationships between goods and services.

Another goal is to investigate situations where the market fails to yield optimal results, known as market failures, and to formulate theories for achieving competitive markets.

Application of Microeconomics

Microeconomics excels in analyzing market dynamics, allowing it to predict consumer expectations from the market. For instance, when the price of a specific product increases in the market, consumer demand for that product generally decreases.

Similarly, if a factory producing a product encounters a fire or similar issues, the price of products manufactured by that factory tends to rise.

Consequently, microeconomics can help predict that a decrease in the sale of a particular product may lead to a decline in the stock value of the producers of that product.

Such insights are valuable for governments, investors, and the general public, aiding them in making informed decisions regarding production, sales, and exchanges.

Common Topics in Microeconomics

Microeconomics encompasses various common topics, some of the most essential of which include:

• Market Structures
• Profit Maximization
• Consumer Behavior
• Producer Behavior
• Supply and Demand
• Game Theory
• Utility Optimization
• Opportunity Cost
• Cost of Production

Similarities between Microeconomics and Macroeconomics

Similarities:

Both microeconomics and macroeconomics use the fundamental principles of economics.

These two branches of economics influence each other, with micro variables impacting macroeconomics.

Behavioral models of households are relevant in both micro and macroeconomics, with their effects extending across various economic aspects.

Foundations of Microeconomics

The story of microeconomics is a tale of market analysis, exploring the intricate dynamics of how buyers and sellers interact in markets, and how prices for goods and services are determined. In essence, the market represents a space where one party sells, and the other buys, with price being the vital force that shapes both supply and demand. Without knowledge of the price, no commodity or product can be exchanged. The price, in turn, is influenced by the interplay between supply and demand. The greater the supply, the more it impacts the price.

Microeconomics delves into the examination of market dynamics, consumer behavior, and the factors driving household decisions in the acquisition of goods and services.

It also scrutinizes the pivotal role that economic entities play as engines driving the economy. A fundamental requirement for understanding microeconomics lies in the comprehension of mathematical models.

To embrace microeconomics, a level of reconciliation with mathematics is necessary. This field of study isn’t confined solely to economics and mathematics but also encompasses the intricate realm of market psychology.

In some contexts, such as the stock market, market psychology and chart reading techniques can hold more significance than technical and fundamental analyses.

In the realm of microeconomics, everything is observed on a small scale, focusing on the intricacies of individual choices and preferences.

It seeks to uncover why individuals make specific choices, what factors render certain goods and services accessible to a select few as luxury items, and what causes others to be available to a broad segment of society.

The field also delves into the factors that make goods and services scarce and the influences of supply and demand elasticity on the sale of goods and services, exploring the determinants of elasticity.
