Supply Shock in the Coffee Market

Effect of a Brazilian frost on equilibrium.

01

Initial market: Qd = 100 − 2P, Qs = 20 + 2P. A frost destroys 30 units of supply at every price.

Initial: 100 − 2P = 20 + 2P ⇒ P* = 20, Q* = 60
New Qs = −10 + 2P

Supply Shock — Coffee Market

Source: Supply Shock in the Coffee Market · Microeconomics

Setup

Microeconomics
  • Qd = 100 − 2P Qs = 20 + 2P
  • Initial: P* = 20, Q* = 60

Shock

Microeconomics
  • Qs' = −10 + 2P
  • 100 − 2P = −10 + 2P ⇒ P*' = 27.5, Q*' = 45

Net effect

Microeconomics
  • Price: ↑ +37.5%
  • Quantity: ↓ −25%

Flashcards

Microeconomics
  • Q: Demand vs quantity demanded? A shift moves the curve; movement along the curve changes only quantity demanded.

How It Works

Three steps. That's it.

  1. 01

    Record Econ Lectures

    Record micro, macro, or econometrics lectures. ThetaWave captures graph shifts, equations, and verbal explanations of economic intuition.

  2. 02

    Models Structured with Assumptions

    Each economic model captured with its assumptions, equations, graphical representation, and real-world applications.

  3. 03

    Concept Cards for Exam Review

    Flashcards for supply-demand models, elasticity formulas, IS-LM curves, and policy analysis — with both math and intuition.

Sound Familiar?

The graph shifted three times before you drew the first one

Supply shifts left, demand shifts right, new equilibrium found — your professor moved on while you're still labeling axes. AI recording captures every shift.

Equations without intuition are meaningless

You memorized the multiplier formula but can't explain why fiscal policy has a larger effect in a closed economy. The math and the story are disconnected.

Econometrics is math + interpretation + code

Your professor explains the OLS estimator, shows the proof, runs Stata output, and interprets coefficients — all in 10 minutes.

Why ThetaWave Helps

Lecture to Notes

models with full context

Record economics lectures. Get each model structured with assumptions, equations, graph descriptions, and the professor's economic intuition.

Flashcard Maker

model cards with graphs + math

Auto-generate cards for IS-LM, AD-AS, game theory matrices, and elasticity — each card includes the formula and the intuitive explanation for exam review.

Why For Economics Students fits ThetaWave better

In this kind of workflow, the real win is not getting a quick answer. It is turning lectures, PDFs, meetings, and readings into material you can keep using later.

Frequently Asked Questions

Everything you need to know about for economics students.

Does Thetawave capture economic graphs and model descriptions?

Yes — Thetawave captures the verbal description of supply-demand shifts, equilibrium conditions, comparative statics, and IS-LM dynamics from lectures. Each model is structured with its assumptions, equations, and the professor's economic intuition.

Can Thetawave handle econometrics formulas and statistical output?

Yes — regression equations, hypothesis tests, OLS estimator proofs, and statistical interpretations are captured with proper notation. You get both the mathematical derivation and the economic interpretation your professor explained.

Does Thetawave work for policy analysis and public economics courses?

Yes — capture policy debates, cost-benefit analyses, and comparative institutional arguments with structured notes that preserve both sides of the analysis. Arguments are organized by policy framework, not chronologically.

Can I generate flashcards that pair formulas with economic intuition?

Yes — Flashcard Maker creates model cards that include the formula, its economic meaning, graph representation, and when to apply it — essential for exam preparation.

Does Thetawave help with game theory and microeconomics problem sets?

Yes — Thetawave captures payoff matrices, Nash equilibria, and strategic reasoning from lectures. Quiz Maker generates practice problems that test both the mathematical solution and the economic interpretation behind each game.
