By the end of this lesson, you should be able to:
- Explain Ricardo's claim that relative value depends primarily on labor required for production.
- Trace why wages and profit move inversely within Ricardo's distributional model.
- Distinguish comparative production costs from the institutions that distribute gains from trade.
Commit to a first explanation.
Two goods take different amounts of time to produce. What other differences would you check before predicting their exchange ratio?
Follow the causal sequence.
Preface and Chapters 1, 5, 6, and 7
David Ricardo
Read with a scope
Read the Preface and Chapter 1 on value, Chapters 5–6 on wages and profits, and Chapter 7 on foreign trade. Note each simplifying assumption before applying a proposition.
Keep one question in view: What does Ricardo's labor measure explain, and where do differences in capital, time, land, or institutions complicate it?
Explain the method without the source.
Watch the analytical operation.
Country A needs fewer hours than Country B to make both cloth and wine, so trade cannot benefit Country A.
-
Separate absolute from comparative cost
Absolute productivity asks who uses fewer hours; comparative cost asks what each country gives up to produce one good rather than the other.
-
Calculate opportunity ratios
Compare cloth in units of forgone wine within each country, not only hours across countries.
-
Identify a possible specialization
Different internal ratios can create room for exchange even when one country is absolutely more productive in both goods.
-
Add movement assumptions
Ricardo's international result assumes capital and labor are less mobile across borders than goods.
-
Separate aggregate gain from distribution
A favorable exchange ratio does not determine which workers, owners, regions, or states capture the benefit.
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.
Two hypothetical cabinet factories use the same labor per identical cabinet, but one pays higher wages; its cabinets must therefore have greater value.
-
Count labor beyond assembly
Assume both factories require the same direct labor and the same past labor embodied in timber, tools, and machinery per cabinet.
-
State the comparison conditions
For this first comparison, also hold capital durability, production time, output prices, and all non-wage costs equal.
Apply the structure to a new case.
Rate both checkpoints, then record this pathway step.
