Study Notes

Opportunity Cost

Choosing one option means giving up another
Explicit cost: monetary sacrifice
Implicit cost: non-monetary sacrifice, like time
The opportunity cost of a choice is the value of the best alternative forgone
Opportunity cost influences the optimal decision

Market Dynamics

People respond to changes in costs and benefits
Increased benefits and decreased costs encourage action
Examples include plastic bag charges and EV incentives

Supply and Demand Model

Shows how prices are determined in a market economy
Explains how prices allocate scarce resources
The "law of demand" states: as prices rise, quantity demanded falls; and as prices fall, quantity demanded rises

Demand

Quantity demanded: the amount buyers are willing and able to purchase
Demand: the relationship between price and quantity demanded
Demand curve: a graph showing the relationship between price and quantity demanded
Individual demand: the maximum amount an individual is willing to pay for a product

Negative Externalities

Occur when market transactions impose costs on third parties not involved in the exchange
Market equilibrium, where supply and demand meet, is higher than the socially optimal quantity
Solutions include imposing taxes on sellers to internalize the externality

Externalities and Market Inefficiency

Negative externalities result in a market quantity larger than socially desirable
Positive externalities result in a market quantity smaller than socially desirable
Internalizing the externality, for example through taxes or subsidies, can correct the inefficiency

Public Policy Toward Externalities

Command-and-control policies regulate behaviour directly, like pollution limits and technology requirements
Market-based policies provide incentives for private solutions, such as corrective taxes and subsidies

Corrective Taxes and Subsidies

Corrective taxes are designed to internalize the social costs of negative externalities
Called Pigouvian taxes after English economist Arthur Pigou
Ideal corrective tax equals the external cost
Corrective subsidies are used for activities generating positive externalities

Private Solutions to Externalities

Coase theorem: When parties can bargain without cost over resource allocation, they can solve externality problems themselves
Examples: tradable permit systems for sustainable use of resources and carbon taxes

Common Resources and Government Role

Policies to prevent overconsumption include:
- Privatization of the resource, making it excludable
- Regulating usage, like Beijing's license plate policy
- Imposing corrective taxes, like hunting licenses
- Auctioning permits, like electromagnetic frequency spectrum, to define property rights and enable market forces

Natural Resource Curse

Mineral resources can lead to resource curse when their abundance doesn't translate to economic prosperity
Countries with abundant resources may experience slower economic growth, weak governance, and social inequality
Strategies to mitigate the resource curse include:
- Investing in human capital, diversification of the economy, and fostering good governance
- Avoiding dependence on resource rents and ensuring that resource revenues are used responsibly
- Investing in infrastructure and technological development to facilitate economic diversification
