Power theory of economics

Power theory of economics 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 Power theory of economics rather than just read about it. In short: Developed by Yasuma Takada in a series of lectures at Kyoto University, the power theory of economics is mostly based on a critique of both mainstream economics as well as heterodox economics theories of unemployment, most notably Keynesian economics and Marxian economics. The theory accommodates Thorstein Veblen, Vilfredo Pareto and Joseph Schumpeter.

Key takeaways

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

Reference excerpt

Developed by Yasuma Takada in a series of lectures at Kyoto University, the power theory of economics is mostly based on a critique of both mainstream economics as well as heterodox economics theories of unemployment, most notably Keynesian economics and Marxian economics. The theory accommodates Thorstein Veblen, Vilfredo Pareto and Joseph Schumpeter. Takada sometimes referred to the theory as a second order approximation, as introducing a theory of power relations into the materialism of economics was seen as one step closer to a true picture of socio-economic relationships.

Worked examples

Example 1 — a first encounter with Power theory of economics

Start with the simplest possible case. Write down what Power theory of economics 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 Power theory of economics 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 Power theory of economics 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 Power theory of economics

In research: Power theory of economics 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 Power theory of economics 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: Power theory of economics is common in secondary-school and first-year university syllabi. It links to neighbouring topics Macroeconomic theories, so understanding it makes those chapters shorter.
In everyday life: Look for Power theory of economics 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.
