Purpose

By the end of this lesson, you should be able to:

  • Distinguish money-capital, productive-capital, and commodity-capital circuits as perspectives on one movement.
  • Explain how turnover time affects the capital required to sustain production and the annual surplus realized.
  • Use reproduction departments to identify interdependence and possible disproportions across the economy.
Start from memory · 3 minutes

Commit to a first explanation.

A profitable firm cannot sell its inventory for six months. What must continue during that delay, and what could interrupt the circuit?

Follow the causal sequence.

Capital, Volume II

Parts I and III: Circuits, Turnover, and Reproduction

Karl Marx

Open the reading

Read with a scope

Read Part I's presentation of the three circuits and selected chapters from Part III on simple and expanded reproduction. Draw each circuit and mark every point where continuity depends on another firm, sector, household, or credit relation.

Keep one question in view: Why can surplus be produced successfully at one point yet the total process of capital still be interrupted?

Closed-book retrieval · 7 minutes

Explain the method without the source.

Close the source. Distinguish the circuits of money capital, productive capital, and commodity capital and explain why none is a separate kind of economy.

Worked example · 8 minutes

Watch the analytical operation.

A seasonal apparel company earns 20% on each batch, so the speed of turnover does not affect its annual result.
  1. Time the advance

    Measure production time, shipping, storage, sale, payment collection, and the wait before money can be advanced again.

  2. Count annual turnovers

    A capital completing four cycles can produce and realize surplus more often than one completing only one.

  3. Identify tied-up capital

    Inventory and receivables require additional money capital to keep wages and suppliers paid during circulation.

  4. Map interruption risk

    Port delays, unsold stock, supplier failure, or credit withdrawal can stop renewal despite successful production.

  5. Connect firms socially

    The company's continuity depends on synchronized replacement across transport, materials, consumer-goods, and finance sectors.

Guided practice · 6 minutes

Complete the missing steps.

The opening steps are supplied. Finish the analysis in your own words, then compare your reasoning before trying the independent case.

A hypothetical economy increases machinery output while reducing workers' consumption goods, so rising investment guarantees balanced reproduction.
  1. Distinguish the departments

    Machinery belongs to Department I, which produces means of production. Workers' consumption goods belong to Department II, which produces means of consumption.

  2. Map one cross-department link

    Machine producers purchase inputs and labor power; their workers need consumption goods. Consumption-goods producers in turn need replacement machinery and materials.

Complete all 3 steps and choose your confidence to reveal feedback. This guided practice stays separate from your two independent checkpoint ratings.

Why does a rise in investment alone fail to establish that both departments can reproduce?

If consumption-goods firms cannot use all the extra machines, what happens along the machine producers' circuit?

What information would establish whether this investment pattern can continue?

How confident are you in these steps?

Independent application · 10 minutes

Apply the structure to a new case.

A semiconductor shortage halts automobile assembly while consumer demand for cars remains strong. Use circuits and reproduction to explain why demand alone cannot restore production.
