PMGM7001 Chap.1 Tariffs, Interdependence and Problem Orientation
Tariffs, Interdependence and Problem Orientation
Why a management course starts with trade policy
The first lecture opens with a group exercise on the United States tariff rollout between February and May 2025. Students use a search engine or an AI platform to rebuild the timeline, interpret its odder details, and then answer two questions: what global management is, and why it matters. The point is method.
The course describes its problems as dynamic, complex and open-ended, with no established or permanent solutions, and asks for problem orientation and an outcome-based approach.
Reading the timeline
The lecture slide lists announcements on China, Mexico and Canada at the start of February, a pause for two partners within days, a memo ordering a trade investigation, further increases in March, a universal tariff in early April, reciprocal tariffs followed by a pause for every partner except China, and a court decision blocking some measures at the end of May.
The exercise is to move from that list to a claim about what the actor intended, and then to test the claim against the dates.
A pause that follows an announcement within days tells you something about purpose that no single rate does.
The four concepts behind paper topic one
The first individual paper topic returns to this episode and names four ideas: self-sufficiency, comparative advantage, deterrence and interdependence. Each answers a different question.
Self-sufficiency asks how far a country can do without others; comparative advantage asks who should make what; deterrence asks whether a credible threat changes behaviour; interdependence asks who is hurt when trade stops.
An answer that uses all four to make one point has not yet told them apart.
What managers take from it
For a firm whose inputs cross a border, the episode is not a debate but an operating environment. The lecture also links the exercise to the cutback on diversity, equity and inclusion funding in the same period, which is the bridge into the diversity topic that follows.

Key terms
- Outcome-based Approach
- A way of analysing a problem that starts from the outcomes an actor may have intended, tests each against the evidence, and only then judges effectiveness.
- Comparative Advantage
- The principle that each party gains by specialising in what it gives up least to produce and trading for the rest.
- Deterrence
- Changing another party's behaviour in advance by making a threatened cost credible, so that the threat works without always being carried out.
- Interdependence
- A relationship in which each party relies on the other, so that ending it is costly to both, which limits how far either can act alone.
Tariffs, Interdependence and Problem Orientation FAQ
Do I need to know economics to answer the tariff topic?
Only at the level of the four named concepts. The topic asks what enabled the stance and what it implies for global management, so the marks come from applying self-sufficiency, comparative advantage, deterrence and interdependence to the episode and to managers, not from technical trade theory. Define each in a sentence and spend your words on application.
Is the tariff exercise politically loaded?
The lecture treats it as an analytical case. It asks what happened, what was effective, why one country could act as it did and what the implications are for managers. You are marked on the quality of that reasoning, so keep evaluative language for claims you have tested against the dated evidence.
What counts as a personal takeaway on this topic?
Something you would do differently as a manager, such as mapping which of your suppliers sit across a border that could be taxed overnight, or building pauses and reversals into scenario plans. A takeaway that only restates the lesson in general terms earns little.
Assessment move
Rebuild the lecture timeline from memory, then write two competing readings of it in three sentences each and name the single dated event that best separates them. That is the whole method of the course in miniature, and it is the paragraph the first paper topic most needs.
