ECO-202: Macroeconomics

A study guide to SNHU's ECO-202, the introductory course on how GDP, inflation, unemployment and policy shape the economy as a whole.

Updated October 2026 · 5 min read

ECO-202 at Southern New Hampshire University is a three-credit introduction to the economy as a whole. SNHU's catalog says students explore GDP, inflation, unemployment, monetary and fiscal policy and international trade, using real examples and economic models and indicators.

The course lists ECO-201 Microeconomics as its prerequisite. Students often find it harder than it looks because it asks for two skills at once: reading data such as GDP or price-index figures, and explaining with a model why a policy change moves them.

What ECO-202 Covers

The catalog description points to five themes. In most courses of this kind each one becomes a block of readings, practice problems and a written or quantitative task.

ThemeWhat you do with it
GDPMeasure output, separate real from nominal, interpret growth
InflationRead price indexes and explain who gains and loses
UnemploymentDistinguish types and connect them to the business cycle
Monetary and fiscal policyTrace how interest rates, spending and taxes move demand
International tradeExplain gains from trade and exchange-rate effects

The catalog also stresses that students apply models and indicators to real events and policy decisions. That means you should be ready to connect a headline, such as a rate change or a jobs report, to the framework from the course.

Key Concepts Explained

Nominal Versus Real GDP

Nominal GDP uses current prices, so it rises when prices rise even if output does not. Real GDP uses base-year prices and shows actual changes in output. The GDP deflator links the two.

Example: Nominal GDP grows from $20.0 trillion to $21.0 trillion, a 5% rise. If the price level rose 3%, real growth is roughly 5% - 3% = 2%. A one-line comparison like this is often the core of a short-answer question.

The Spending Multiplier

When government spending rises, income rises, and part of that income is spent again. The simple multiplier is 1 / (1 - MPC), where MPC is the marginal propensity to consume.

Example: With an MPC of 0.8 the multiplier is 1 / 0.2 = 5, so a $10 billion spending increase raises demand by up to $50 billion. Your analysis should then say why the real effect is usually smaller, for instance because of taxes, imports and crowding out.

Aggregate Demand and Supply

The AD-AS model shows how shocks move the price level and output. A fall in consumer confidence shifts AD left, lowering output and prices in the short run. A rise in oil prices shifts short-run supply left, raising prices while cutting output.

The Unemployment Rate

The rate is the unemployed divided by the labor force, not by the whole population. People who stop looking drop out of the labor force, which is why the rate can fall for bad reasons.

Example: A labor force of 160 million with 8 million unemployed gives 8 / 160 = 5%. If 2 million of them give up searching, the rate becomes 6 / 158, about 3.8%, even though nobody found a job.

Frequently Asked Questions

What is the prerequisite for ECO-202?

SNHU's catalog lists ECO-201 Microeconomics, so you should be comfortable with supply, demand and basic graphs.

How many credits is ECO-202?

It is a three-credit undergraduate course in SNHU's catalog.

Is ECO-202 mostly maths?

There is some algebra and percentage work, but most marks come from explaining models and data in words.

What is the difference between ECO-201 and ECO-202?

ECO-201 looks at individual markets and firms. ECO-202 looks at the economy as a whole: output, prices, jobs and policy.

Do I need to draw graphs by hand?

Check the instructions for each task. Many accept a clearly labeled digital graph.

Can you check my ECO-202 draft?

Yes. Send the draft and rubric and we review logic, graphs and wording and explain our changes.
