Study Notes
Scope of Economics
- Economics examines how agents make choices with limited resources and how these choices impact society.
- The core concept is choice, not wealth or money.
- Economic agents include individuals, households, firms, and governments, who generally make optimal choices.
- Scarce resources are goods or services insufficient to meet everyone's needs.
- Positive economics describes actual economic agent behavior using objective analysis and facts. It avoids value judgments. (e.g., mean wage in sectors, gender income gap determinants)
- Normative economics prescribes what economic agents should do, often leading to policy recommendations. (e.g., best job offer, policies to reduce income gap)
Microeconomics
- Focuses on individual economic agents (households, firms, etc.) and their choices.
- Analyzes how these choices affect prices, resource allocation, and other agents' well-being.
- Examines specific aspects of the economy, not the entire system.
- Includes topics like consumer choice, market design, and firm behavior.
Macroeconomics
- Studies the economy as a whole.
- Examines aggregate production, inflation, economic cycles, labor markets, monetary policy, etc.
- Analyzes the overall performance of a country's economy.
- Includes topics such as the impact of labor reforms on unemployment and GDP or assessing economic stimulation programs.
Principles of Economics
Optimization
- Aims to find the best possible choice given available information.
- Requires considering feasible options, available information, and personal preferences.
- Involves trade-offs, where choosing one option means giving up another.
- Budget constraints limit available choices.
- Opportunity cost is the value of the best alternative use of resources.
- Cost-benefit analysis compares benefits and costs in a common unit.
Equilibrium
- A state where no agent can benefit by changing their behavior.
- Exists in various situations, including queues, markets, and political campaigns.
- Assumes agents make optimal decisions.
Empiricism
- Utilizes data to answer economic questions.
- Separates correlation from causation.
- Correlation describes the relationship between variables (e.g., crowded beaches and high temperatures).
- Causation establishes a direct cause-and-effect relationship.
- Emphasizes the use of data over anecdotes.
Economic Models and Data Analysis
- Models are simplified representations of reality.
- The scientific method includes building models, formulating hypotheses, testing with data, and refining based on outcomes.
- Models are useful simplifications, like a simplified map of a city, but may not precisely reflect complex realities.
- Correlation vs. Causation:
- Omitted variables: Aspects not included in a model that may influence cause-and-effect relationships.
- Reverse causality: Determining cause and effect is complex; factors should be closely examined.
- Experiments: Controlled experiments provide strong evidence for cause and effect.
- Natural experiments: Observe events to identify potential cause-effect.
- Causation vs Correlation: Key differences include omitted variables, reverse causality, and experiments.
Cost-Benefit Analysis and Optimization
- Evaluate costs and benefits in the same unit for optimal decision-making.
- Optimize decisions using total net benefit (benefits – costs), comparing across choices.
- Marginal analysis focuses on changes in costs and benefits between choices.
- Optimization can be limited by factors like: incomplete information, cost of information gathering, lack of expertise, and trade-offs.
Choosing and Commuting
- Reasons for commuting costs: Availability of public transport, fuel costs, parking fees, vehicle maintenance, and time opportunity costs.
