Study Notes

Microeconomics Overview

Microeconomics focuses on how individuals and businesses make decisions about allocating scarce resources.
It examines the exchange of goods and services for money.

Understanding Money

Money serves as a medium of exchange, unit of account, means of final settlement, and store of value.

Market Dynamics

Markets are formed by interactions between buyers (consumers) and sellers (producers).
Both parties aim to benefit from transactions.

Decision-Making and Scarcity

Scarcity means human wants exceed available resources, forcing us to make choices.
The “best” choice maximizes benefit, considering both the willingness to pay (WTP) and explicit cost (EC).

Net Benefit and Opportunity Cost

Net benefit (NB) is calculated as WTP minus EC, the difference between the value we place on something versus its explicit cost.
Opportunity cost is what we give up when making a choice, including both the explicit and implicit costs.
Implicit costs represent the net benefit of the best foregone alternative.

Marginal Analysis

Marginal analysis breaks down decisions into smaller "yes/no" choices considering marginal benefits (MB) and marginal costs (MC).
The rule: Continue taking an action as long as MB ≥ MC.

Timing and Sunk Costs

Decisions depend on current benefits and costs, not past costs.
Sunk costs are unrecoverable and should be ignored when making decisions.

Applying Marginal Analysis: Example

Taking a pizza analogy, each slice costs $5.
The first and second slices are consumed because MB ≥ MC.
The third slice is not consumed because MC > MB.
