Study Notes
General Economics Study Notes
- Economics is the study of how society allocates its scarce (limited) resources to satisfy unlimited wants.
- Choices are made by considering the expected benefits and costs of decisions, and their consequences.
- Microeconomics studies the economic behavior of individual decision-makers (consumers, firms, etc.) and markets.
- Macroeconomics examines the overall economy and its aggregates (like GDP, inflation, unemployment).
Model Building in Economics
- Models simplify complex real-world situations.
- Exogenous variables are taken as given outside the model.
- Endogenous variables are determined within the model.
Constrained Optimization Models
- Economists use constrained optimization to model situations where decision-makers want to choose the best outcome given limitations or constraints.
- In mathematical terms, the relationship to be optimized is call the objective function, and the limitations or conditions the constrains to the problem.
Equilibrium Analysis
- Equilibrium analysis examines states or conditions that will persist until an outside factor causes change.
- Markets move towards equilibrium where quantity demanded equals quantity supplied and price is in balance
Comparative Statics
- Comparative Statics can be used to calculate how one variable will affect another following a change in an exogenous variable
Cost-Benefit Approach
- If the benefit of an activity exceeds its cost, do it.
- Reservation Price is the price at which a person is indifferent between doing an activity and not doing it.
- Market prices are often determined by the tension between buyers' desire for lower prices and sellers' desire for higher prices.
Positive and Normative Economics
- Positive economics describes how the economy actually works.
- Normative economics offers recommendations about how the economy should operate.
Ceteris Paribus Assumption
- All other relevant factors are constant, while analyzing the effects of one factor
