Do the exercises and show your work
7–14 weeks (8 hrs/week)
Take International Trade for free and do the problem sets (comparative advantage, factor endowments, scale, firms in trade, tariffs and trade policy). Keep your answers in one public place (a repo, a shared folder or a page) as you go, with your reasoning shown.
Proof required
Link your public folder with the problem sets (comparative advantage, factor endowments, scale, firms in trade, tariffs and trade policy), and show your self-check (14.54: problem sets and exams).
What gets checked
- Models are solved correctly.
- Gains and losses are shown by group.
- Exam answers are marked with the corrections.
Common mistakes
- Answers copied from a key: verifiers read the reasoning.
- Numbers with no working.
- Asking for review before the self-check.
Powstik Guide
A public folder with your worked answers to the problem sets (comparative advantage, factor endowments, scale, firms in trade, tariffs and trade policy).
Steps
- Make a public folder or repo for this course.
- Do one chapter or problem set at a time and save it.
- Self-check: Do each problem set and exam under time, then mark yourself against the solutions where the course posts them. Where it does not, rework the numbers in a spreadsheet and check that every total ties out.
- Fix what the self-check shows, and say what you fixed.
- Ask three people who know the topic to check it.

- Models are solved correctly.
- Gains and losses are shown by group.
- Exam answers are marked with the corrections.
- Pick two answers and check every step.
- Ask about one step; the answer should be clear.

Trace one country's trade
1–3 weeks (5–8 hrs/week)
Use what you learned. Make a note on one country's trade in one product, from public trade data: partners, volumes over 10 years, what changed after one policy event, and what trade theory predicts. Put it where verifiers can open it. Use public information, or data you have permission to use; never publish a real person's private details.
Proof required
Link a note on one country's trade in one product, from public trade data: partners, volumes over 10 years, what changed after one policy event, and what trade theory predicts, and a short note on what you decided or changed because of it.
What gets checked
- The trade data source is named and the code or sheet is open.
- The policy event is dated and the change is measured.
- Theory is compared with the data honestly.
Common mistakes
- Invented or unsourced figures.
- A conclusion the evidence does not support.

A note on one country's trade in one product, from public trade data: partners, volumes over 10 years, what changed after one policy event, and what trade theory predicts.
Steps
- Write one line: what you will show.
- Gather the real data, people or documents.
- Draft it, then read it cold the next day.
- Ask someone to mark the first claim they doubt.
- Fix it and ask three people to check it.
