Microeconomics

Contract Theory

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

Before You Dive In

Contract Theory belongs to microeconomics: the study of choice, incentives, and market interaction under scarcity.
Rough timeline: marginal revolution -> formal general equilibrium and game theory -> information and mechanism design -> applied empirical micro.
Start with optimization plus constraints; most micro models are variations on that core structure.
In Noosaga, compare frameworks by friction assumptions: perfect information, strategic behavior, contracts, or market power.

Utility maximizationModel of choice where agents select bundles that maximize preferences under constraints.

General equilibriumSimultaneous determination of prices and allocations across interlinked markets.

Game theoryFramework for strategic interaction where outcomes depend on others' actions.

Mechanism designDesign of rules and incentives to achieve desired outcomes with private information.

Information asymmetrySituations where different agents hold different information, affecting efficiency.

Treating models as literal reality rather than disciplined simplifications for specific questions.

Assuming competitive equilibrium is always socially desirable once distribution and externalities are considered.

Confusing individual rationality with collective optimality.

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.
