    Study Notes

    Scarcity

    • Society has limited resources
    • Individuals can’t produce all the goods and services they desire
    • Individuals have unlimited needs and wants
    • Economic choices must be made due to scarcity
    • Economics studies how society manages scarce resources

    Trade-offs

    • Individuals face trade-offs because choices involve opportunity costs
    • The term "free lunch" implies no trade-offs, which doesn’t exist
    • Examples of trade-offs: investment vs. consumption, efficiency vs. equality
    • Example: A student with 120 hours to study must decide the optimal allocation of time between subjects
    • Example: Choosing to learn instead of play involves comparing the benefits of each activity

    Thinking at the Margin

    • Rational individuals make decisions by comparing marginal benefits and marginal costs
    • A marginal change is a small adjustment to an existing plan
    • Rational decision-makers prioritize actions with marginal benefits exceeding marginal costs
    • Example: Deciding how to spend the last hour before bedtime
    • Example: Deciding between pizza and ice cream, considering satisfaction from each after consuming different quantities

    Incentives

    • Individuals respond to incentives, both positive and negative
    • Policies influence actions by changing the costs or benefits associated with them
    • Institutions shape economic behavior by determining costs and benefits
    • Fundamental institutions define economic systems
    • Example: Innovation in planned economies, where rewards did not reflect the true value of innovation, failed to incentivize inventors

    Trade

    • Trade can benefit all participants by allowing for specialization
    • Countries can specialize in activities they perform best and enjoy a wider variety of goods and services

    Markets

    • Markets organize economic activity through decentralized decision-making by firms and households
    • The “invisible hand” guides economic activity through price signals
    • Market prices efficiently convey information and incentivize participants
    • Example: Information deficit in planned economies, where centralized planners couldn't efficiently process available information

    The Government

    • Government intervention can improve market outcomes in cases of market failure
    • Market failure occurs when markets alone fail to allocate resources efficiently
    • Externalities, such as pollution, can lead to market failure
    • Market power, where a single actor influences prices, can also lead to market failure
    • Example: Industrial policy, where governments intervene to support targeted industries for future export success

    Productivity

    • Productivity, the output per unit of labor input, determines a nation’s living standard
    • Differences in productivity account for most variations in living standards across countries

    Inflation

    • Inflation is an increase in the overall price level and often results from an excess supply of money
    • Government printing of large quantities of money can devalue the currency and cause inflation
    • Inflation erodes the purchasing power of money

    Unemployment

    • The economy faces a short-term trade-off between inflation and unemployment
    • Increasing the money supply can lower unemployment but might lead to inflation
    • Economic cycles, which are fluctuations in economic activity, influence both inflation and unemployment
