Industrial organization

Industrial organization is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Industrial organization rather than just read about it. In short: Industrial organization or industrial economics is a field of economics that analyzes the structure and behavior of firms and imperfectly competitive market structures. It introduces real-world features that depart from the model of perfect competition, such as transaction costs, imperfect information, and barriers to entry faced by potential competitors.

Key takeaways

Industrial organization belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Industrial organization to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Industrial organization from memory before moving on to harder problems.

Reference excerpt

Industrial organization or industrial economics is a field of economics that analyzes the structure and behavior of firms and imperfectly competitive market structures. It introduces real-world features that depart from the model of perfect competition, such as transaction costs, imperfect information, and barriers to entry faced by potential competitors. The field studies how firms and markets are organized and how they behave across a spectrum ranging from competitive markets to monopoly, including cases shaped by government intervention and regulation. Industrial organization combines theoretical models and empirical analysis to study issues such as market power, competition policy, oligopoly behavior, pricing strategies, vertical integration, and the design of contracts and institutions. It has applications in public policy, business strategy, and the regulation of industries. There are different approaches to the subject. One approach is descriptive in providing an overview of industrial organization, such as measures of competition and the size-concentration of firms in an industry. A second approach uses microeconomic models to explain internal firm organization and market strategy, which includes internal research and development along with issues of internal reorganization and renewal. A third aspect is oriented to public policy related to economic regulation, antitrust law, and, more generally, the economic governance of law in defining property rights, enforcing contracts, and providing organizational infrastructure. The extensive use of game theory in industrial economics has led to the export of this tool to other branches of microeconomics, such as behavioral economics and corporate finance. Industrial organization has also had significant practical impacts on antitrust law and competition policy. The development of industrial organization as a separate field owes much to Edward Chamberlin, Joan Robinson, Edward S. Mason, J. M. Clark, Joe S. Bain and Paolo Sylos Labini, among others.

Subareas The Journal of Economic Literature (JEL) classification codes are one way of representing the range of economics subjects and subareas. There, Industrial Organization, one of 20 primary categories, has 9 secondary categories, each with multiple tertiary categories. The secondary categories are listed below with corresponding available article-preview links of The New Palgrave Dictionary of Economics Online and footnotes to their respective JEL-tertiary categories and associated New-Palgrave links.

JEL: L1 – Market Structure, Firm Strategy, and Market Performance JEL: L2 – Firm Objectives, Organization, and Behavior JEL: L3 – Non-profit organizations and Public enterprise JEL: L4 – Antitrust Issues and Policies JEL: L5 – Regulation and Industrial policy JEL: L6 – Industry Studies: Manufacturing JEL: L7 – Industry Studies: Primary Products and Construction JEL: L8 – Industry Studies: Services JEL: L9 – Industry Studies: Transportation and Utilities

Market structures The common market structures studied in this field are: perfect competition, monopolistic competition, duopoly, oligopoly, oligopsony, monopoly and monopsony.

History of the field A 2009 book Pioneers of Industrial Organization traces the development of the field from Adam Smith to recent times and includes dozens of short biographies of major figures in Europe and North America who contributed to the growth and development of the discipline. Other reviews by publication year and earliest available cited works those in 1970/1937, 1972/1933, 1974, 1987/1937-1956 (3 cites), 1968–9 (7 cites), 2009/c. 1900, and 2010/1951.

Worked examples

Example 1 — a first encounter with Industrial organization

Start with the simplest possible case. Write down what Industrial organization claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Industrial organization before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Industrial organization ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Industrial organization

In research: Industrial organization appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Industrial organization in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Industrial organization is common in secondary-school and first-year university syllabi. It links to neighbouring topics Industrial organization, Market (economics), so understanding it makes those chapters shorter.
In everyday life: Look for Industrial organization outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Industrial organization in simple terms?

Why does Industrial organization matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
