Macroeconomics

Growth Theory

This guide helps you get your bearings in Growth Theory before you start exploring the interactive timeline, framework graph, and concept maps.

Before You Dive In

Growth Theory sits inside macroeconomics: how output, inflation, employment, and policy interact at economy-wide scale.
Rough timeline: Keynesian demand management -> monetarist and expectations critiques -> RBC and New Keynesian synthesis -> heterogeneous-agent and financial-friction models.
Start with accounting identities and the IS-LM/AS-AD intuition before moving to dynamic stochastic models.
Use Noosaga to compare frameworks by shock source and adjustment mechanism: prices, expectations, policy rules, or balance sheets.

Aggregate demandTotal planned spending in the economy at different price levels.

Potential outputSustainable production level consistent with stable inflation pressures.

Phillips curveRelationship framework between inflation dynamics and labor market slack.

DSGE modelDynamic stochastic general equilibrium model used for policy and cycle analysis.

Fiscal multiplierEstimated change in output from a change in government spending or taxes.

Treating accounting identities as causal mechanisms.

Assuming one historical period can validate a full macro framework by itself.

Confusing short-run stabilization tools with long-run growth determinants.

Open the interactive view and scan the framework timeline. Which frameworks came first? Which ones overlap? Where are the big transitions?

Click into individual frameworks to read what each one claims, where it came from, and how it relates to its neighbors.

See how the key ideas within a framework connect. This is useful for figuring out what to learn first and what depends on what.

Take the quiz for any framework you've read about. It's a quick way to find out whether you actually understood the core ideas or just skimmed them.
