Kumu / Econ & Trade
International Economics & Trade
Trade, tariffs, and exchange rates — learned by actually importing a product. Your team finds a product on Alibaba, prices it against Amazon, brands it, and sells it to your classmates. Every classmate gets $200 to spend. Highest net profit wins extra credit.
Stage 0 — get GitHub working, before the project
The whole project lives in a shared repo: research, brand system, listing, model, both decks, and the prompt log all move by branch → pull request → review → merge. That stops dead if one teammate cannot commit and push, so every member gets GitHub working before the first milestone below — not on the night of it.
It comes in two parts: the account, then the workspace.
Part 1 — Get a GitHub account never used GitHub? start here
Create the account and learn the three verbs — add → commit → push.
If you already have a GitHub account you can use that: sign in, add your
hawaii.edu address, and go straight to part 2. If not, sign up with that
hawaii.edu address — it is what unlocks GitHub Education.
Part 2 — Set up your workspace
Stand up your own public portfolio repo, built to the standard and named for you. The team repo below runs on exactly these mechanics — branches, commits, pull requests — and your personal repo is where your own work lands, this course and every one after it.
Part 1 in full: the Git mechanics walkthrough
Start Here → Git mechanics walks the whole workflow once: local versus remote, add → commit → push in the desktop app and on the command line, editing files straight on github.com, and fixes for the mistakes everyone makes the first time. Read it before part 2 — the workspace page assumes you can already save work to a repo, and does not re-teach the mechanics.
The team project — import something real
The rules are simple and the economics are not: find a low-cost wholesale product with a high retail price, survive the tariff, and convince 24 classmates to spend their $200 budget on your product instead of every other team's. Two 5-minute presentations carry the grade; a shared GitHub repo carries the work.
Product Scout, Brand & Sales Pitch Presentation #1
Shortlist 3 products from Amazon's top sellers, pick one, define your team's brand as a
design.json design system, and ship a fake Amazon listing — live on GitHub Pages —
that sells the class in 5 minutes.
Suppliers, Tariffs & Unit Economics Presentation #2
Top-5 Alibaba suppliers, real HTS tariff lookup (AI-suggested, officially verified), and the landed-cost model: wholesale + tariff + freight → profit per unit → what the class can actually afford. Excel workbook included.
Deliverables & grading (unchanged from the syllabus)
| Deliverable | Format | Weight |
|---|---|---|
| Shortlist — top 3 candidate products | Email to Prof. Stauffer | — |
| Final product + price | Email to Prof. Stauffer | — |
| Presentation #1: Sales | 5 min to class + email | 2.5 pts |
| Presentation #2: Unit Economics | 5 min to class + email | 5.0 pts instructor + 7.5 pts peer review |
| Forms & surveys (3) | At presentation time | −0.5 each if missing (max −1.5) |
| 360 intrateam peer review | Survey | Multiplier on your team score |
| Profit contest | Quantity sold × profit per unit | Extra credit: 3 / 2 / 1 pts for top 3 teams |
Market rules: each student gets $200 to spend on other teams' products. Don't price above $200 (nobody can buy it); be careful pricing very low (you'd need huge volume). Your classmates are your entire economy — that constraint does more teaching than any lecture.
How the team repo works
One GitHub repo per team — the same discipline as the Micro/Macro team case and the Performance Ratios portfolio repo. Slides, research, the brand system, the listing, the model, and the prompt log all live there and move by branch → pull request → teammate review → merge. No email attachments between teammates, ever.

Practice first
Econ Policy Lab
Impose a tariff on a live supply-and-demand model and watch who really pays it — the incidence question your Presentation #2 must answer for your own product.
AI Tools Lab
The field guide to coding LLMs: chat vs "code" tools, web vs desktop vs CLI, and why giving the AI your repo is the single biggest upgrade. Read it before your first AI build session.
Kumu knows this course
Ask the ✳ tutor to stress-test your product pick against the $200-budget market, explain landed cost, or play a skeptical classmate who doesn't want your dryer balls. Log the session — that's your prompt log.
Verify everything
AI drafts, humans verify: every price gets an Amazon/Alibaba screenshot, every tariff rate gets checked at hts.usitc.gov. An unverified number in a deck costs more than it saves.
