Problems no single country can solve
- A global issue 全球性议题 crosses borders, so no government can fix it inside its own.
- Climate, pandemics, migration, the movement of money: the list changes, the structure does not.
- Learning the structure transfers to an issue you have never studied, which is what the exam actually rewards.
The shared structure
- A shared resource 共有资源 that everyone can use and nobody owns.
- An externality 外部性 where the cost of an action falls on someone other than the person deciding.
- A collective action problem 集体行动问题 where everyone would gain from a solution that nobody wants to pay for alone.
- Name those three in an unfamiliar issue and you have the beginning of an analysis rather than a description.
Which three elements recur in global issues? Choose all that apply.
Usually everyone knows what would work. The problem is that no actor gains by moving first.
Measuring development
- Development 发展 is measured by more than income: health, education and inequality all appear in composite indicators.
- Two countries with the same average income can differ enormously in how long people live and how long they study.
- ⚠ An average hides a distribution. A rising mean income is compatible with most people getting poorer.
If average income is rising, most people must be getting richer.
An average hides a distribution. A rising mean is compatible with most people getting poorer.
Two countries have the same average income. What else must you look at?
Composite indicators exist because income alone describes very different lives identically.
One structure, two issues.
Overfishing: the sea is the shared resource, the cost of one more boat falls on everyone else, and every country would gain from limits nobody wants to accept first.
Air pollution: the atmosphere is the shared resource, the cost of one more factory falls downwind, and every city would gain from standards each is reluctant to impose alone.
Different subjects, identical structure. That is why naming the structure is worth more than listing examples.
Overfishing and air pollution share what?
Which is why the structure transfers to an issue you have never studied.
Name the shared resource and the externality in traffic congestion.
The road is the shared resource; each additional car delays everyone else, and that delay is the externality.
A global issue is rarely a shortage of knowledge. Usually everyone involved knows what would work and no actor gains by moving first — which is why the analysis has to be about incentives, not about awareness.
Keep to issues with good data and low political temperature: urbanisation, public health, education access, water, food systems, energy. The method is what is assessed, and a topic that invites heat rather than evidence works against you.
