1  What is managerial economics?

Learning outcomes
  • Understand the core principles and scope of managerial economics.
  • Analyze the application of managerial economics in personal and professional decision-making.
  • Explain the connections between managerial economics and other social science disciplines.

As a student, you might wonder what managerial economics really is. Well, there isn’t a single well-accepted definition. However, there are certain ideas that many people agree on.

In simple terms, managerial economics is about applying economic theories to make better decisions in business and management. It’s about using tools from economics to solve real-world problems that companies face every day. That means, any sort of method, information, and knowledge from economic research that can help managers in making good decisions.

If you’re curious about what most people mean by managerial economics, sources like Wikipedia can give you a good starting point. While I wouldn’t suggest citing Wikipedia in academic papers1 or using ChatGPT to generate text, it can provide helpful, widely accepted definitions and give you an overview of the topic.

Me: Define managerial economics

ChatGPT (4.0):

Managerial economics is a discipline that combines economic theory with managerial practice. It helps in analyzing business situations and decision-making processes within an organization. By applying microeconomic principles and tools, managerial economics aids managers in planning, optimizing resource use, forecasting future conditions, and making strategic decisions that enhance the organization’s performance. It encompasses various aspects of both economics and business, such as demand analysis, production and cost functions, pricing strategies, risk analysis, and capital budgeting.

Key areas of focus in managerial economics include:

Demand Analysis and Forecasting: Understanding consumer behavior and predicting future market trends to make informed decisions.

Production and Cost Analysis: Evaluating the production process and cost functions to optimize efficiency and reduce expenses.

Pricing Decisions: Developing pricing strategies that maximize profits while remaining competitive in the market.

Profit Management: Analyzing profit margins and identifying ways to increase overall profitability.

Risk and Uncertainty Analysis: Assessing and managing risks associated with business decisions.

Capital Budgeting: Making decisions about long-term investments and capital expenditures.

Overall, managerial economics provides a framework for systematically thinking about business decisions and executing strategies to achieve organizational objectives.

Me: What distinguishes managerial economics from Microeconomics and Macroeconomics?

ChatGPT (4.0):

Managerial economics, microeconomics, and macroeconomics are all subfields of economics, but they differ in their focus, scope, and application. Here’s how they are distinguished from one another:

Managerial Economics

Scope and Focus:

Organizational Level: Primarily focuses on the firm or organization, aiming to solve specific managerial and business problems.

Decision-Making: Applies economic theories and principles to managerial decision-making processes, such as pricing, production, costs, and resource allocation.

Practical Application: Designed to be directly applicable by managers for optimizing business operations and strategic planning.

Microeconomics

Scope and Focus:

Individual and Firm Level: Concentrates on the behaviors of individuals, households, and firms.

Market Mechanisms: Studies how these entities interact within markets, how prices are determined, and how resources are allocated.

Theoretical Framework: Provides the underlying theories that explain demand and supply, elasticity, consumer behavior, production, and costs.

Macroeconomics

Scope and Focus:

Economy-Wide Perspective: Looks at the entire economy rather than individual units.

Aggregate Indicators: Studies large-scale economic factors such as national income, unemployment rates, inflation, GDP, and overall economic growth.

Policy Implications: Often deals with government policies, monetary and fiscal policy, and their impact on the economy as a whole.

Key Differences

Scale:

Managerial Economics: Focuses on optimizing decisions within individual firms or organizations.

Microeconomics: Explores the behavior of individual agents such as consumers and firms.

Macroeconomics: Examines aggregate economic variables and economy-wide phenomena.

Application:

Managerial Economics: Directly used by managers to make practical business decisions.

Microeconomics: Provides foundational theories that inform both managerial economics and broader economic policies.

Macroeconomics: Used by policymakers to shape economic policy and understand economic fluctuations on a national or global scale.

Objective:

Managerial Economics: Goal-oriented towards improving organizational efficiency and profitability.

Microeconomics: Aims to understand the fundamental aspects of supply and demand and market mechanisms.

Macroeconomics: Seeks to explain economic trends and issues that affect the economy as a whole.

In essence, while managerial economics draws heavily from microeconomic theories, it is distinct in its focus on practical application within firms. Macroeconomics, on the other hand, operates at a higher level of abstraction, dealing with broad economic indicators and policies.

1.3 What is economics?

All economic questions arise because we want more than we can get. Our inability to satisfy all our wants is called scarcity and because of scarcity, we must make choices that depend on the incentives we face. An incentive is a reward that encourages or a penalty that discourages an action.

Economics is a social science, and as in all social sciences, many of the terms used in it are poorly defined. The following quotes can demonstrate that:

John Maynard Keynes (1883-1946): “The theory of economics does not furnish a body of settled conclusions immediately applicable to policy. It is a method rather than a doctrine, an apparatus of the mind, a technique of thinking, which helps it possessors to draw correct conclusions.” Keynes (1921)

Alfred Marshall (1842-1924): “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.” Marshall (2009, p. 1)

Gary S. Becker (1930-2014): “Economics is all about how people make choices. Sociology is about why there isn’t any choice to be made.” Becker (1960, p. 233)

Colander (2006, p. 4): “Economics is the study of how human beings coordinate their wants and desires, given the decision-making mechanisms, social customs, and political realities of the society.”

Colander, D. C. (2006). Economics (6th ed.). McGraw-Hill Irvin.

Parkin (2012, p. 2): “Economics is the social science that studies the choices that individuals, businesses, governments, and entire societies make as they cope with scarcity and the incentives that influence and reconcile those choices.”

Gwartney et al. (2006, p. 5.): “[E]conomics is the study of human behavior, with a particular focus on human decision making.”

Backhouse & Medema (2009, p. 222): “[E]conomics is apparently the study of the economy, the study of the coordination process, the study of the effects of scarcity, the science of choice, and the study of human behavior.”

Greenlaw & Shapiro (2022, ch. 1): Economics seeks to solve the problem of scarcity, which is when human wants for goods and services exceed the available supply. A modern economy displays a division of labor, in which people earn income by specializing in what they produce and then use that income to purchase the products they need or want. The division of labor allows individuals and firms to specialize and to produce more for several reasons: a) It allows the agents to focus on areas of advantage due to natural factors and skill levels; b) It encourages the agents to learn and invent; c) It allows agents to take advantage of economies of scale. Division and specialization of labor only work when individuals can purchase what they do not produce in markets. Learning about economics helps you understand the major problems facing the world today, prepares you to be a good citizen, and helps you become a well-rounded thinker.

Backhouse & Medema (2009, p. 222): “Perhaps the definition of economics is best viewed as a tool for the first day of principles classes but otherwise of little concern to practicing economists.”

Jacob Viner (1892-1970): “Economics is what economists do.” Backhouse & Medema (2009, p. 222)

Parkin (2012, p. 2): “Microeconomics is the study of the choices that individuals and businesses make, the way these choices interact in markets, and the influence of governments. […] Macroeconomics is the study of the performance of the national economy and the global economy.”

Parkin, M. (2012). Economics (10th ed.). Addison-Wesley.

Although many textbook definitions are quite similar in many ways, the lack of agreement on a clear-cut definition of economics does not really matter and does not necessarily pose a problem as

“[E]conomists are generally guided by pragmatic considerations of what works or by methodological views emanating from various sources, not by formal definitions.” Backhouse & Medema (2009, p. 231)

The important questions of economics: How do choices end up determining what, where, how, and for whom goods and services get produced? And: When do choices made in the pursuit of self-interest also promote the social interest?

I am the author of the Managerial Economics course and I am currently looking for a cover image for my book. I have reached out to several art and marketing companies for suggestions. Now imagine you are a sales representative from one of these companies and you have designed the cover shown in the image Figure 1.1. You have three minutes to make a compelling sales pitch that convinces me to choose your design. What would you say in those three minutes?
