What is the difference between microeconomics and macroeconomics?
What is the difference between microeconomics and macroeconomics?
Microeconomics studies the economic behavior of individual decision makers, while macroeconomics studies how an entire national economy performs.
Why is economics often described as the science of constrained choice?
Why is economics often described as the science of constrained choice?
Because our wants for goods and services are unlimited, but the resources to produce them are limited.
How does the tool of constrained optimization help decision makers make choices?

Study Notes
Difference Between Microeconomics and Macroeconomics
- Microeconomics focuses on individual economic decision makers such as consumers, workers, and firms.
- Macroeconomics examines the performance of an entire national economy, including aspects like interest rates, inflation, and business cycles.
Constrained Choice in Economics
- Economics is often termed the science of constrained choice due to the scarcity of resources against unlimited wants.
- Limited resources include labor, capital, and raw materials, meaning that choices about goods and services are restricted.
Constrained Optimization Tool
- Constrained optimization aids decision makers by helping them select the optimal choice while considering limitations and restrictions.
Objective Function and Constraints in Optimization
- The objective function indicates what needs to be maximized or minimized.
- Constraints define the limitations on choices and help determine the set of possible alternatives.
Market Equilibrium Explanation
- A price above equilibrium ($5.00) leads to excess supply as consumers buy less than suppliers sell.
- A price below equilibrium ($2.50) results in excess demand, prompting consumers to bid prices upward.
Opportunity Cost Concept
- Opportunity costs illustrate that all actions involve trade-offs due to limited resources.
Economics Statements - True/False
- All provided statements about the distinctions between microeconomics and macroeconomics and resource allocation are true.
Examples of Constraints
- A valid constraint example is represented as 2A + 4B < 30.
Consumer Satisfaction Objective Function
- The consumer's objective function for maximizing satisfaction is B) max H + F.
Exogenous Variable Definition
- An exogenous variable is considered given in economic analysis, originating from outside the system.
Endogenous Variable Definition
- An endogenous variable's value is determined within the economic system being analyzed.
Key Analytical Tools in Microeconomics
- Constrained optimization
- Equilibrium analysis
- Comparative statics
Constrained Optimization Defined
- This analytical tool assists in making optimal choices considering any possible limitations.
Objective Function Explained
- The objective function expresses the relationship that the decision maker aims to optimize (maximize/minimize).
Constraints Definition
- Constraints impose restrictions or limits on decision makers in an optimization context.
Marginal Concepts in Microeconomics
- The term marginal indicates how a dependent variable changes with the addition of one unit of an independent variable.
Marginal Cost Definition
- Marginal cost measures the impact of producing one additional unit of output on total costs.
Equilibrium Definition
- Equilibrium is a stable state that persists as long as external factors remain unchanged.
