ECON102: ace the component, not just read the notes
Your complete guide to University of Wisconsin-Madison's principles of macroeconomics course. See where the marks are, work real practice questions, and study with an AI tutor that knows ECON102.
Sia generates ECON102 practice questions, walks through national income accounting and unemployment step by step, and quizzes you on the material the component that weights most heavily.
Worked example
Nominal GDP rises by 6% in a year while the price level rises by 4%. What happened to real GDP, approximately?
Nominal GDP changes for two reasons: more output, or higher prices for the same output.
6% - 4% = about 2%, so real output grew by roughly 2%.
Note the approximation: the exact calculation divides the index rather than subtracting, which matters when the numbers are large.
The trap: Adding the two, or reporting the nominal figure as growth. The whole reason national income accounting comes first in this course is that aggregate figures are constructed, and a number that has not been deflated is measuring prices as much as production. classic slip!
Overview
What ECON102 is, and where it sits
ECON 102 is UW-Madison's introduction to macroeconomics: macroeconomic measurement and models of aggregate demand and supply, then fiscal and monetary policy for unemployment, inflation and growth. It carries 4 credits and takes ECON 101 as its prerequisite.
The course divides into measurement and models. Measurement comes first because the aggregate variables are constructed rather than observed: what output is, what counts as unemployment, and how a price level is built. The models then use those variables to explain why output and employment fluctuate and what policy can do about it.
Because it assumes ECON 101, the pace differs from the micro introduction. There is no re-teaching of supply and demand; it is applied at the aggregate level in the first weeks. Students who took ECON 101 some time ago usually need to refresh it before the semester rather than during it.
Always treat your own course outline and the exam timetable as authoritative.
Difficulty & time commitment
Is ECON102 hard, and how much time does it take?
ECON102 is manageable if you keep a weekly rhythm and treat the back half as the main event. The pattern is consistent: it starts gently and steepens, and the heaviest assessment is the part that separates grades.
The difficulty curve and the assessment weighting point the same way: the back half is harder and worth more. Front-loading effort there is the highest-return decision in the course.
Is this course for you
Who tends to do well, and who tends to struggle
You will likely do well if
- You refresh ECON 101 before the semester rather than during it.
- You are comfortable with constructed measures and their limitations.
- You can argue a policy case from a model rather than from opinion.
- You keep nominal and real quantities separate as a habit.
You may struggle if
- You expect the course to restart from first principles.
- You skip the accounting weeks as bookkeeping; everything later uses those definitions.
- You treat policy questions as invitations for opinion.
- You confuse short-run and long-run analysis, which the aggregate supply material exists to separate.
- Write each aggregate variable's definition in one line, including what it excludes.
- For any shock, trace output, unemployment and inflation together rather than one at a time.
- Practise the short-run versus long-run distinction until it is automatic.
- Deflate every nominal figure you meet, as a reflex.
Syllabus
The 8 topics, topic by topic
The exam-weight marker on each topic shows where the marks concentrate. The amber topics carry the highest exam weight.
T1 · National income accounting
Course descriptionWhat output measures, how it is constructed, and what it leaves out. The definitions here carry the whole course.
T2 · Unemployment and the labour market
Course descriptionHow unemployment is measured, what the measure misses, and what determines it.
T3 · Inflation and the price level
Course descriptionBuilding a price index, reading it, and separating nominal changes from real ones.
T4 · Aggregate demand
Course descriptionThe demand side of the whole economy, and why it slopes as it does.
T5 · Aggregate supply
Course descriptionThe supply side in the short and long run, and the distinction that makes policy analysis possible.
T6 · Fiscal policy
Course descriptionGovernment spending and taxation as instruments, and their limits.
T7 · Monetary policy
Course descriptionMoney, interest rates and the central bank's tools for acting on inflation and unemployment.
T8 · Economic growth
Course descriptionWhat raises output per person over the long run, as distinct from what moves it in the short run.
How it's assessed
Assessment structure
A component-by-component weighting breakdown is not published for this course. Rather than estimate one, we publish only what the course itself states. Check your current course outline for the exact percentages.
No component weighting is published. The university catalogue publishes course description, credits, requisites, course designation and learning outcomes, but not assessment weights, and instructor syllabi carrying them are set per section and per term. Rather than estimate a breakdown or reuse a superseded one, none is asserted here. Check the syllabus your instructor posts for this term. Not published in the catalogue. Format is set per section by the instructor.
How to actually pass it
A weekly rhythm, two checklists, and the traps to avoid
The course rewards consistency over cramming, and practice over re-reading. Here is the loop that works, then what to have nailed before each exam.
The weekly loop
Before the mid-semester checklist
- National income accounting, including what output excludes
- Unemployment measurement and its limitations
- Price indices, and the nominal-real distinction
- Aggregate demand and what shifts it
Before the final heaviest topics
- Aggregate supply in the short and long run
- Fiscal policy and its limits
- Monetary policy and the transmission to inflation and employment
- Long-run growth as distinct from short-run fluctuation
The mistakes that cost marks
Reporting nominal growth as growth. Without deflating, you are reporting prices and output together. This is the first thing the course teaches and the most common exam slip.
Treating unemployment as a simple count. The measure depends on who counts as in the labour force, which is why the definition is examinable.
Mixing short-run and long-run reasoning. Policy conclusions differ between them, and answers that blur the two lose the argument.
Shifting the wrong curve. As in micro, the diagram is the argument; the wrong shift cannot be rescued by correct prose.
Formula & concept sheet
The vocabulary and formulas you must own
- GDP
- The market value of final goods and services produced in an economy over a period.
- Real versus nominal
- Real quantities are adjusted for price changes; nominal ones are not.
- Price index
- A constructed measure of the general price level, used to deflate nominal figures.
- Unemployment rate
- The share of the labour force without work and seeking it, which depends on how the labour force is defined.
- Aggregate demand
- Total planned spending in the economy at each price level.
- Aggregate supply
- Total output firms are willing to produce, with different short-run and long-run behaviour.
- Fiscal policy
- Government spending and taxation used to influence aggregate outcomes.
- Monetary policy
- Central bank action on money and interest rates.
- Economic growth
- The long-run increase in output per person, driven by capital, labour and productivity.

FAQ
Frequently asked questions
What is the prerequisite?
ECON 101, or A A E 101 (215 prior to Fall 2024). It is not open to students with credit for ECON 111.
How many credits?
The catalogue lists 3-4 credits, and it carries Core General Education in Social and Behavioral Science plus Social Science breadth at elementary level.
How is it graded?
The catalogue publishes no weighting. Assessment is set per section, so use your instructor's syllabus for this term.
Is it harder than ECON 101?
Slightly, mainly because it assumes ECON 101 rather than rebuilding it. The aggregate models arrive quickly.
Is the course still running?
Yes. The catalogue records it as last taught in Summer 2026.
What is the difference from ECON 111?
ECON 111 integrates micro and macro in one accelerated course, especially for the Economics: Math Emphasis major. Taking 111 precludes 101 and 102.
