To the student with an exam coming up,
Print this document today. Not tonight, not after your shift, today. A PDF on a phone is a document
you scroll past; paper on a desk is a document you fight with. You will write on these pages, cross
out wrong numbers, and draw arrows. If you cannot print at home, most university libraries have
student printing, and a printed booklet costs less than a coffee at Centraal. This is the first instruc‐
tion and the easiest one. Do it before you read any further theory.
Now buy one notebook. Clean, empty, no old lecture notes in the back, at least eighty pages. In
that notebook you will write every single calculation step by hand, with the numbers substituted,
until the notebook is full. Not the answer. The steps. When you compute an openness ratio you
write Openness = (X + M) / GDP x 100 = (€48.0 billion + €52.0 billion) / €250.0 billion x 100 =
40.0%, and then one short line saying what 40.0% means: this country trades the equivalent of
40.0% of its output. The word openness means how exposed an economy is to foreign trade. Stu‐
dents who only type answers into a calculator lose marks in Dutch exams because partial credit is
awarded for visible, correct intermediate steps. No steps on paper, no points on the exam. It is that
mechanical.
Protect your study time, within reason. If your situation allows it, ask your employer for fewer shifts
or a short break until the exam. Many students genuinely cannot do that, because rent, visa condi‐
tions or family obligations do not pause for an exam, and I am not going to pretend otherwise. So
here is the realistic alternative: two protected study blocks around each shift. Ninety minutes be‐
fore you leave for work, sixty minutes after you come home, phone face down in a drawer in both.
That is two and a half hours on a working day. Before the exam, that is enough to fill the notebook.
Do not study in your room. Pack the bag the night before: printed booklet, notebook, two pens, cal‐
culator, water, and leave. Work where other people are visibly working. Your university library, a
public library or a quiet study room are all reasonable options; check their current opening times
and access rules yourself, because these change and I will not invent them for you. Focus is conta‐
gious, and so is distraction. You are choosing which one sits next to you.
Last thing, and it is the one that decides your grade. After every attempt, grade yourself with the
Self-Grading Scorecard below, brutally. If you looked at the answer halfway through, that attempt
scores zero on independence. If your units are missing, you lose the unit point even though the
number is right, because the exam will take it too. A kind score today buys you a failed exam later.
An honest score today tells you exactly which page to redo tomorrow. I would rather see you angry
at a 4 out of 10 in your notebook than calm and unprepared in the exam hall.
The time before your exam is short, but it is not nothing. Start with the printer. Then the notebook.

How to grade yourself
1. Score the attempt you actually made, not the one you could have made with five more minutes. Time
pressure is part of the exam.
2. If you opened the answer key, a worked example or your notes at any point during the attempt, the
independence criterion scores zero. No exceptions, no half points.
3. Mark a missing unit, a missing currency sign or an undeclared rounding as lost points, because a Dutch
examiner marking for partial credit will do exactly the same.
4. Write the score and the single sentence 'What I got wrong and why' under every attempt, in ink, before you
move on. No sentence, no score counts.
5. Never erase a wrong attempt. Cross it out once and leave it visible; the booklet is evidence of progress, not
a clean copy.

Core Concepts & Variable Mechanics
That is what you have, and that is enough, but only if you stop reading theory and start rebuilding numbers. This mod‐
ule gives you the six models that produce most of the technical marks in International Economics and Business: the
openness ratio, comparative advantage under constant costs, consumer and producer surplus with tariff and quota ef‐
fects, the effective rate of protection, the foreign trade multiplier, and the exchange rate pair of purchasing power par‐
ity and the real exchange rate. For each one you get the formula, every symbol with its exact unit, the mechanical
chains that say which number must move when another number moves, a fully worked micro example with every multi‐
plication visible, and the trap that costs students points. Work with a pen. Copy each micro example once while read‐
ing, then close the page and redo it from blank paper. All businesses and figures below are invented for teaching; any
resemblance to a real firm's accounts is coincidental. Rounding is stated every time, because in past exams the in‐
structions on this course have been explicit about rounding and students have lost marks by ignoring them.

17TH EDITION
Openness ratio (trade patterns)
It is the cheapest marks on the paper: one division, one multiplication, and a two-sentence interpretation that separates a small open economy
from a large closed one.
The openness ratio measures how much a country trades compared with the size of its economy. You add exports and im‐
ports, which together are called total trade, then divide by Gross Domestic Product, the money value of everything the coun‐
try produces in a year. Multiply by 100 to express it as a percentage. Note what this number is not: it is not the trade balance.
Exports and imports are added, not subtracted, so a country with a huge deficit can still be very open. A ratio above 100 is
possible and normal for small economies such as the Netherlands or Singapore, because re-exported goods pass through
ports and are counted twice, once entering and once leaving, while GDP only counts the value added inside the country.
Openness = ((Exports + Imports) / GDP) x 100
Symbol Variable Unit Role in the model
Exports of euros per year, or % of GDP if the table already gives percentages Raises total trade; pushed up by
goods and foreign demand, a weaker home
services currency, and trade liberalisation
Imports of euros per year, or % of GDP if the table already gives percentages Raises total trade exactly like exports;
goods and pushed up by home income and by
services removing tariffs
