ESG Flashcards
Public good
both non-excludable and non-rivalrous
Categorical Imperative
Act as you would want all other people to act towards all other people, as if it was a universal law.
Economic Freedom
the fundamental right of every human to control his or her own labor and property
Consumer sovereignty
the situation in an economy where the desires and needs of consumers control the output of producers.
Opportunity Cost
The sum of the dollar values of the best-foregone alternative
What does the gov do?
1) Provides a stable trading environment (law and macro policy).
2) Provides certain goods and services (education, national defence, utilities, healthcare, infrastructure).
3) Makes regulations (labour law, environmental, financial, competition, housing, etc.)
4) Taxes and subsidies
5) Redistributes wealth and provides for the underprivileged (welfare).
Marginalist principle
Any policy should be carried out as long as marginal benefit > marginal cost
Sunk cost
an expense that’s already been incurred and can’t be recovered (not relevant to decision making)
Which costs are relevant to decision-making
Opportunity costs, accounting costs, (externalities?)
Paradox of value
diamonds cost more than water but water is more essential this is because prices are determined ON THE MARGIN. People will pay very high prices when it is scarce vs for diamonds ppl would pay less but since it is scarce vs water is not people pay more for diamonds. The current prices of these goods are different due to the difference in supply.
The law of unintended consequences
policies that fail due to perverse incentives.
Perverse
people adjust their behaviour to a policy’s incentive in
ways that counteract the policy’s intended effect
Example of perverse incentives
Capping interest rates at 4% promotes illegal high-interest-rate payday lending.
People driving more recklessly when they have more safety features in their cars.
Peltzman effect (and example)
Individuals respond to safety laws by engaging in more dangerous activities, which balances out cautious behaviour.
ex. Safety features in cars increase the number of non-fatal crashes.
ex. Opioid use in the US. As naloxone access increased, the number of ER visits increased but the mortality rate DID NOT CHANGE. People’s actions completely offset the effects of the policy.
The laffer curve
Increased tax rates increase tax revenues to a certain point and then decrease them as people as encouraged to move away or work less hard.

^Upside down quadratic function
Ex. free doctors visits, unemployment insurance
Examples of incentives crowding out intrinsic motivations.
a. donating blood
b. day-care centre late fees (people picked up their kids on time but then a fee for late pickup increased the amount of people who picked up late as they felt they were allowed)
3 takeaways about incentives
a. Use opportunity costs not accounting costs to evaluate policies.
b.It’s not all or nothing. : Expand beneficial policies up to the point where marginal benefits equal marginal (opportunity) costs.
c. Well-intended policies can have undesired impacts, often because of failure to consider incentive effects.
- Even attempts to use incentives can go wrong.
- Many well-intended policies actually do work because the unintended consequences are small or even negligible.
Private ownership/decentralized (competition)
Market capitalism (private enterprise)
Public/decentralized (competition)
Market socialism (ex. China)
Private/centralized
Monopoly Capitalism
Public/centralized
State-directed socialism
Market economy
prices and quantities for most goods and services are determined in competitive markets.
- Prices determined by supply and demand
- Demand represents the aggregate preferences of consumers (consumer sovereignty)
- Goods are supplied by individuals/firms pursuing profitable opportunities (economic freedom)
Economic Freedom
Consenting adults can engage in mutually advantageous transactions.
Backed by institutions through
a. Secure system of private property rights
b. Freedom of contract: freely choose contract partner and rules of enforcement
Freedom of contract
freely choose contract partner and rules of enforcement
Consumer sovereignty
The consumer is the ultimate determiner of what will be made and sold and consumed.
Limitations on consumer sovereignty
BBC and the £159 (in 2021) TV license fee;
Germany has €210 annual TV license fee regardless of use.
legal drinking ages (19 in BC)
government-funded anti-smoking campaigns
China’s one child policy (changed in 2016 to two-child policy)
Limitations on economic freedom
Some transactions are illegal:
sell your organs
sell (or buy) drugs
sell alcohol to minors
to hire child workers
“people smuggling”
sell babies
sell or buy prohibited firearms
Low economic freedom examples
Venezuela, Cuba, North Korea
High economic freedom examples
Singapore, Switzerland, Ireland, Taiwan, Luxembourg, NZ, Estonia, Denmark, Sweden, and Norway (1-10)
Examples of the benefits of market economies
Countries divided after WWII: Korea, Germany, China/Taiwan.
West Germany (capitalist) vs East Germany (socialist). People migrated to West. Incomes in West were/are still higher.
South Korea (capitalist) vs North Korea (socialist). South Korea has a much higher GDP per capita and much higher output overall.
Taiwan (Capitalist) vs China (socialist). Taiwan is more productive.
Adam Smith’s invisible hand
Founder of capitalist theory.
By pursuing his own self-interest, the entrepreneur frequently promotes that of society more effectually than when he means to promote it.
Self-interested individuals end up doing what’s best for society in a free-market scenario. Producers are motivated to produce what’s socially necessary when consumer sovereignty is present.
(Similar to Milton Friedman’s magic of the market).
Ex. Steve Jobs had to make the apple iphone a fantastic product to be competitive in the smartphone market. He was motivated by his own profit.
First Welfare Theorem
Under perfect competition, markets achieve pareto efficiency.
Perfect competition (3 things)
a. No one seller has the power to set prices: sellers and buyers are price takers.
b. Entry of new firms (or exit of unprofitable firms) drives profits to zero.
c. Buyers and sellers have all info. No transaction costs.
ex. blueberries (no one cares who they buy them from)
Efficiency (2 kinds)
“Absence of waste”
a. Management efficiency
b. Pareto efficiency
Management efficiency / Production efficiency
a given level of output being produced at lowest input usage
lowest cost
Pareto efficiency / Allocation efficiency
appropriate amount of each good is produced
impossible to re-allocate the resources among a group of people in such a way as to make at least one person better off without making anybody else worse off
No DWL, market equilibrium is Pareto efficient (CS and PS are maximized)
^Economists give more emphasis to this
Why do economists care more about pareto/allocation efficiency over management/production efficiency.
In market theory, economists assume that competition will reduce the costs of all firms as unprofitable firms will go out of business.
Pareto improvement
at least one person is made better off while no one is made worse off
(rare in practice)
Potential Pareto improvement
re-allocation of resources allows those individuals who are net gainers to fully compensate the net losers, and still be better off.
ex. removing rent controls, expanding dairy quotas
(more common in practice, unsure whether the gainers actually compensate the losers)
Deadweight loss
A DWL is a reduction in economic efficiency when market equilibrium for a good/service is not achieved.
- Deviation from Pareto effiency
- Sum of gaps between willigness to pay and cost of supply
- DWL is wasteful because money was left on the table and mutually beneficial transactions were not realized.
Distortion
When Gov policies change the level of output produced and consumed away from QC. (This can cause DWL)
- Gains to winners are less than losses to the losers in this case. Creates a triangle of DWL.
Macro failure
economy-wide failure to keep workers and capital fully employed.
