Flashcards

What is an economic model?

A representation of a theory, using a simplified description that can be logical and easy to understand. These descriptions can come in the form of words, pictures, or mathematical expressions. The art of creating these descriptions is achieved by making specific assumptions.

Demand and Supply Model

The simplified framework that helps us understand how prices are determined and how quantities of goods and services are bought and sold in an economy.

What is Consumer Theory?

Understanding what influences consumer decisions and what factors drive their purchases.

What is Producer Theory?

Understanding how businesses make decisions, how they choose to produce goods and services, and the costs associated with those choices.

When is a market a good model to use?

All of the assumptions of the demand and supply model must be true for the insights derived to be valid. In other words, when the assumptions are met, the model becomes a useful tool. We can then use the model to predict how prices and quantities will change in response to various events.

Study Notes

Cornell Method for Note-Taking

  • The Cornell Method is recommended for taking notes during lectures and reading
  • Use a page divided into sections: Cue column, Note-taking column, and Summary
  • Record key terms, questions, and main ideas in the Cue column
  • Record detailed notes, diagrams, and formulas in the Note-taking column
  • Summarize the notes in your own words in the Summary section

Intermediate Microeconomic Theory

  • The course covers the relationship between scarcity, trade-offs, and decision-making
  • It examines the three key trade-offs faced by every society
  • It explains the fundamental role of price in a market economy

What is Microeconomics?

  • Microeconomics studies the behavior of individual economic agents, like consumers and firms.

Scarcity

  • Scarcity is a fundamental economic concept
  • Resources are limited, while wants are unlimited
  • This creates a need for trade-offs

Trade-offs

  • Trade-offs are decisions made because of scarcity
  • Choosing one option means foregoing another

The Bigger Picture - the What, How, and Who?

  • Scarcity of resources forces societies to make choices about production, consumption, and distribution of goods

Perfect Competition

  • A market structure in which producers are price takers
  • Assumptions include many small producers, no barriers to entry, homogenous goods

Price Mechanism

  • Price acts as a signal in market economies
  • Price directs resources to where they are most valued
  • Price motivates incentives for both production and consumption

Economic Models

  • Models are simplified representations of reality
  • Economists use models to understand economic phenomena and make predictions
  • Models help to isolate variables and simplify complex interactions

Positive vs. Normative Analysis

  • Positive statements describe "what is" (facts, data)
  • Normative statements express values, opinions, or "what ought to be"

Main Themes in Intermediate Microeconomic Theory

  • Main theme #1: Economic agents make themselves as well off as possible given limited resources
  • Main theme #2: Price is crucial in decision-making and economic interactions
  • Main theme #3: Economists use theories, models, and empirical evidence for analysis

Models: Representation of a Theory

  • Economists represent theories through verbal, visual or mathematical descriptions
  • Models have logical and simplified descriptions of economic interactions
  • Models include specific assumptions

Why is this so Important?

  • Studying demand and supply is essential in microeconomic theory
  • Students should understand the theories behind demand and supply

Real World is Complex

  • The real-world is significantly more complex than simple models can reflect

What is a Market?

  • Markets are central to economic study, typically involving a specific product, location, and time period
  • Markets connect consumers and producers through price as a signal

Key Assumptions and Analysis

  • Perfectly competitive markets have implicit assumptions about the agents, good, information, and institutions.
  • Analysis of models explores when the model assumptions hold, and when it can be used to help make predictions

When to Use the Model

  • Models provide predictions about demand and supply shocks and the impact of policy
  • Useful in various markets: agriculture, finance, labor, etc.
