Rate of exploitation

Rate of exploitation 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 Rate of exploitation rather than just read about it. In short: In Marxian economics, the rate of exploitation is the ratio of the total amount of unpaid labor done (surplus-value) to the total amount of wages paid (the value of labour power). The rate of exploitation is often also called the rate of surplus-value.

Key takeaways

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

Reference excerpt

In Marxian economics, the rate of exploitation is the ratio of the total amount of unpaid labor done (surplus-value) to the total amount of wages paid (the value of labour power). The rate of exploitation is often also called the rate of surplus-value.

Divergence of the two rates Marx did not regard the rate of surplus value and the rate of exploitation as necessarily identical, insofar as there was a divergence between surplus value realised and surplus value produced. Thus, the quantity of surplus labour performed by workers in an enterprise might correspond to a value higher or lower than the surplus value actually realised as profit income upon sales of output. The implication is that if the gross profit volume was related to wage costs to establish the rate of surplus value, this might overstate or understate the real rate of labor-exploitation. Although this is a subtle point, it has sometimes played an important role in wage bargaining negotiations by trade unions. For an extreme example, workers might work extremely hard in an enterprise which nevertheless operates at a loss. For another extreme example, workers might work less hard, knowing that their product will sell like hotcakes in a seller's market at sharply inflated prices, yielding profits disproportionate to labour input. The divergence between surplus value realised and surplus value produced becomes even more marked if surplus value is viewed in terms of the net incomes of social classes, i.e. net labor income and net property income. Marx identified five different formulae for the rate of surplus value (see surplus value).

Worked examples

Example 1 — a first encounter with Rate of exploitation

Start with the simplest possible case. Write down what Rate of exploitation 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 Rate of exploitation 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 Rate of exploitation 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 Rate of exploitation

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