Definition: The key goals of economic policy are efficiency, equity, economic growth, and stability.
Relevance: Determines government intervention in taxation, welfare, and monetary policy.
How It Works: Policies like fiscal policy (taxes) and monetary policy (interest rates) are designed to achieve these goals.
Who/When/Why/How:
Who: Policymakers, governments, and central banks.
When: Used in response to economic shocks and recessions.
Why: To ensure sustainable economic growth, fairness, and stability.
How: Trade-offs are made between equity and efficiency in policies like welfare.
Example: COVID-19 stimulus checks promoted stability but increased debt, showing a trade-off.
Definition: An allocation of resources where no one can be made better off without making someone else worse off.
Relevance: Serves as a benchmark for economic efficiency.
How It Works: In perfect competition, markets achieve Pareto efficiency.
Who/When/Why/How:
Who: Used by policymakers and economists.
When: Used to judge market outcomes and resource allocation.
Why: To ensure resources are used optimally.
How: Markets must have perfect information, perfect competition, and no externalities.
Example: A perfectly competitive market is Pareto efficient.
Definition: The government's role in setting rules, protecting property rights, and fixing market failures.
Relevance: Justifies welfare, taxes, public goods, and market regulation.
How It Works: The state intervenes when markets fail or when public goods are under-supplied.
Who/When/Why/How:
Who: Government agencies like the EPA, CBO, and Federal Reserve.
When: During market failures (like the 2008 financial crisis).
Why: To ensure efficiency, equity, and public welfare.
How: Uses laws, regulations, and taxes to achieve social goals.
Example: EPA regulations reduce pollution and address externalities.
Definition: The idea that improving fairness (equity) reduces economic efficiency.
Relevance: Justifies welfare programs and progressive taxation.
How It Works: Redistribution (like welfare) reduces efficiency by introducing deadweight loss.
Who/When/Why/How:
Who: Policymakers debate tradeoffs when designing tax systems.
When: Used to analyze programs like welfare and unemployment benefits.
Why: To balance fairness (equity) with efficiency in policy.
How: Governments impose progressive taxes to improve fairness.
Example: Minimum wage laws improve fairness but reduce efficiency by increasing costs for firms.
Definition: Decision-makers create fair rules as if they didn't know their social position.
Relevance: Justifies welfare programs and redistribution to protect the vulnerable.
How It Works: By imagining themselves as the "worst-off," decision-makers create rules that maximize fairness.
Who/When/Why/How:
Who: Used in social contract theory by John Rawls.
When: Used to support welfare policies.
Why: To ensure fairness and redistributive justice.
How: Encourages progressive tax policies and universal healthcare.
Example: Justifies universal healthcare and programs like food stamps (SNAP).
Definition: Maximize the welfare of the least-advantaged members of society.
Relevance: Supports policies that reduce inequality.
Example: Progressive taxation benefits low-income households.
Definition: Emphasizes minimal government intervention and protection of property rights.
Relevance: Opposes redistributive taxation and supports a "minimal state."
Example: Opposition to welfare and support for low taxes.
Definition: The unequal distribution of income, wealth, and opportunity.
Methods to Measure:
Gini Coefficient
Quintiles/Deciles
Income/Wealth Disparity
Target of Measures: Labor Income, Capital Income.
Example: The top 1% controls 40% of wealth in the U.S.
Definition: Total income from two primary sources:
Labor Income: Wages, salaries, and employment-related earnings.
Capital Income: Income from ownership of assets like dividends, interest, capital gains, and rents.
Relevance: The split between labor income and capital income determines income inequality and wealth inequality.
How It Works: Labor income is earned through work, while capital income comes from returns on investments.
Who/When/Why/How:
Who: Workers receive labor income, while investors receive capital income.
When: Capital income becomes more relevant as wealth accumulates.
Why: High-income individuals receive most of their income from capital, while low-income individuals rely on labor.
How: Policies like taxes on capital gains affect income inequality.
Examples:
Labor Income: Wages earned from a 9-5 job.
Capital Income: Dividends from owning stocks or rental income from property ownership.
Definition: The growing gap between high-income and low-income individuals.
Relevance: Drives debates on progressive taxation, wealth taxes, and wage increases.
How It Works: Increases in capital income for the wealthy drive inequality, while wages (labor income) remain stagnant.
Who/When/Why/How:
Who: Wealthiest 1% receive the majority of capital income.
When: Inequality grew after the 1980s due to lower taxes on capital gains and less unionization.
Why: The rich earn more capital income than the poor.
How: Government intervention can reduce inequality via progressive taxation and welfare.
Example: The top 1% of U.S. households control 40% of the nation's wealth, while most of the bottom 50% rely on labor income.
Definition: The key argument is that in low-growth economies, returns on capital (r) exceed returns on labor (g), leading to rising inequality.
Relevance: Explains the increasing gap between capital owners and wage earners in the U.S.
How It Works: If the rate of return on wealth (r) is greater than the economic growth rate (g), then wealth becomes more concentrated.
Who/When/Why/How:
Who: Wealth holders grow richer while workers stay stagnant.
When: Post-1980s, after tax cuts on capital gains.
Why: Wealth grows faster than wages, causing inequality.
How: Capitalists gain from returns on stocks, dividends, and rents.
Example: Billionaires like Jeff Bezos and Elon Musk grow wealthier due to returns on stock, while workers' wages barely increase.
Definition: Rules or laws set by the government to control market activity.
Relevance: Reduces market failures like monopolies and externalities.
How It Works: Governments pass laws, rules, and standards to control market behavior.
Who/When/Why/How:
Who: EPA (environmental regulations), FTC (anti-monopoly), SEC (financial regulations).
When: Often passed after crises (e.g., after the 2008 financial crisis).
Why: To protect consumers, reduce externalities, and prevent monopolies.
How: Laws like the Clean Air Act and Sherman Antitrust Act.
Example: Clean Air Act regulates pollution to reduce environmental harm.
Definition: Different periods of intense regulatory action in U.S. history.
Key Waves:
Progressive Era (1890-1920): Sherman Antitrust Act (break up monopolies).
New Deal (1930s): SEC created to regulate stock markets after the Great Depression.
Great Society (1960s): Focused on civil rights, health, and environmental issues (created the EPA).
Reagan Era (1980s): Deregulation of banking, airlines, and telecom.
Relevance: Each era of regulation responded to a major crisis or need.
Example: The 2008 financial crisis led to the Dodd-Frank Act to regulate Wall Street.
Definition: When the market fails to allocate resources efficiently.
Causes: Monopolies, externalities, and public goods.
Relevance: Justifies government intervention in the market.
Example: Monopolies increase prices, and externalities (pollution) reduce social welfare.
Definition: Costs or benefits that affect third parties.
Negative Externality: Pollution (cost to society).
Positive Externality: Education (benefit to society).
How It Works: Externalities cause misallocation of resources, leading to market failure.
Solution: Taxes on negative externalities (like pollution taxes) or subsidies for positive externalities (like education grants).
Example: Carbon taxes reduce emissions and address climate change.
Definition: A market-based system to reduce pollution by issuing permits to polluters.
Relevance: Limits total pollution and allows firms to trade permits, creating incentives to reduce emissions.
How It Works: Firms receive permits for emissions, but they can buy/sell them based on need.
Who/When/Why/How:
Who: Used in the Regional Greenhouse Gas Initiative (RGGI).
When: Introduced in the U.S. in the 2000s to address climate change.
Why: To limit greenhouse gas emissions.
How: Caps total emissions and allows firms to buy/sell pollution permits.
Example: RGGI (Regional Greenhouse Gas Initiative) is a U.S. cap-and-trade program to reduce CO2 emissions.
Definition: Non-rival, non-excludable goods (meaning one person's use doesn’t reduce availability for others).
Examples: Clean air, public parks, national defense.
How It Works: Markets fail to provide public goods because of the free-rider problem.
Solution: Government intervention (taxes) is required to fund public goods.
Relevance: Justifies taxes to pay for goods like national defense and public health.
Example: The U.S. military is funded by taxes and provides defense for all citizens.
Definition:
Public Prisons: Run by the government.
Private Prisons: Run by private firms under contracts with the government.
Relevance: Raises issues of accountability, cost-cutting, and profit motives in criminal justice.
How It Works: Private prisons reduce costs by cutting staffing and services.
Criticism: Private prisons have incentives to increase incarceration rates.
Example: GEO Group and CoreCivic run for-profit private prisons.
Public vs Private:
Public Prisons: Focus on rehabilitation and reducing recidivism.
Private Prisons: Focus on cost reduction and profit maximization.
Definition: A situation where one party (usually the buyer) has more information about the quality of a product than the other party (usually the seller), causing higher-quality sellers to exit the market.
How It Works: In health insurance, people with pre-existing conditions are more likely to buy health insurance, but insurers can’t perfectly identify who is a high-risk customer.
Why It's a Market Failure:
Low-risk people (healthy people) leave the market, leaving only high-risk (sick) people, which raises insurance premiums.
This leads to an under-provision of health insurance.
Relevance: Explains why health insurance markets fail without mandates or risk pooling.
Who/When/Why/How:
Who: Buyers (patients) have more information about their health than insurance companies.
When: Occurs in health insurance markets and used car markets.
Why: Insurers can't perfectly predict who will be sick, so they raise premiums.
How: Mandatory insurance requirements (like the ACA individual mandate) fix this problem.
Example: Before the Affordable Care Act (ACA), people with pre-existing conditions could be denied health insurance because insurers feared that only the sick would sign up.
Definition: When people change their behavior and take on more risk because they are protected from the consequences.
How It Works: If people have health insurance, they might use more healthcare services than necessary (since they're not paying the full cost).
Why It Matters: It causes overuse of healthcare services, leading to higher insurance premiums.
Relevance: Explains why insurers use deductibles, co-pays, and co-insurance to reduce overuse.
Who/When/Why/How:
Who: Insurance policyholders (people with health, auto, or homeowners insurance).
When: Happens in any market where risk is transferred from the buyer to the insurer.
Why: People behave more recklessly when they don’t have to bear the full cost of their actions.
How: Insurers use deductibles and co-pays to force customers to pay a portion of the cost.
Example: People might visit the doctor for minor ailments more frequently if their health insurance has no co-pay.
Definition: The amount you must pay out of pocket before insurance begins to cover costs.
Relevance: Reduces moral hazard by making individuals responsible for some costs.
Who/When/Why/How:
Who: Anyone with health, car, or homeowners insurance.
When: Deductibles are paid annually or per-incident, depending on the insurance type.
Why: To reduce moral hazard and limit overuse of services.
How: Insurance doesn't pay until the deductible is met.
Example: If your deductible is $500, you pay the first $500 in medical expenses before the insurance company pays.
Uncertainty of Demand: You don’t know when you’ll need healthcare (like an emergency).
Asymmetric Information: Patients know more about their health than insurers.
Market Failures: Caused by adverse selection, moral hazard, and public good aspects of healthcare.
Relevance: These features explain why healthcare is not like other markets.
Who/When/Why/How:
Who: Buyers (patients) and sellers (doctors, hospitals, and insurers).
When: Happens in every healthcare market.
Why: People have different health risks, so they don't all face the same healthcare costs.
How: Governments intervene with regulation and subsidies to address these failures.
Example: Because of asymmetric information, people with undiagnosed health conditions may buy insurance at standard rates, raising costs for insurers.
Definition: A U.S. federal health insurance program for seniors (65+), younger people with disabilities, and certain illnesses.
Relevance: Reduces elderly poverty by covering healthcare for seniors.
Parts of Medicare:
Part A: Covers hospital stays (funded by payroll taxes).
Part B: Covers doctor visits and outpatient care.
Part C: Medicare Advantage (allows private insurance plans to offer Medicare benefits).
Part D: Covers prescription drugs.
Who/When/Why/How:
Who: People aged 65+ and people with certain disabilities.
When: Became law in 1965 as part of Lyndon B. Johnson's Great Society.
Why: To reduce poverty among seniors and improve access to healthcare.
How: Funded through payroll taxes, general revenues, and premiums.
Example: Seniors 65+ receive hospital coverage under Medicare Part A.
Definition: A state and federal program that provides healthcare to low-income individuals and families.
Relevance: Reduces poverty and improves healthcare for vulnerable populations.
How It Works: Funded by both the federal government and states. Each state sets its eligibility rules.
Who/When/Why/How:
Who: Low-income families, pregnant women, children, and people with disabilities.
When: Established in 1965 under President Lyndon B. Johnson.
Why: To provide healthcare for vulnerable populations.
How: States manage Medicaid with federal matching funds.
Example: Medicaid expansion under the ACA increased coverage for low-income adults.
Definition: A 2010 law that reformed the U.S. healthcare system by expanding Medicaid, creating health insurance exchanges, and eliminating pre-existing condition exclusions.
Relevance: Reduced the number of uninsured Americans and fixed adverse selection issues.
How It Works:
Guaranteed Issue: Insurers can't deny coverage due to pre-existing conditions.
Subsidies: Provides financial aid for low-income families to buy insurance.
Medicaid Expansion: States can expand Medicaid to cover more low-income people.
Individual Mandate: Required people to buy insurance or face a penalty (later eliminated in 2017).
Who/When/Why/How:
Who: Everyone in the U.S. is affected (especially the uninsured).
When: Became law in 2010 under President Barack Obama.
Why: To reduce the number of uninsured people and control healthcare costs.
How: Combines subsidies, mandates, and regulations to reduce market failures.
Example: The ACA prevented insurers from denying coverage for pre-existing conditions.
Guaranteed Issue: Insurance companies must offer policies to everyone, regardless of pre-existing conditions.
No Price Discrimination: Insurers cannot charge different premiums based on health status.
Individual Mandate: People must buy health insurance or pay a tax penalty (until 2017).
Subsidies: Low-income individuals receive federal subsidies to buy insurance.
Medicaid Expansion: States can expand Medicaid to cover more people.
Relevance: Reduced uninsured rates and fixed the adverse selection problem.
Example: People with pre-existing conditions like diabetes could no longer be denied coverage.
Definition: A market structure where firms have market power, unlike in perfect competition where no firm can control the price.
Relevance: Explains monopolies, oligopolies, and rent-seeking behavior in markets.
Types of Imperfect Competition:
Monopoly: One seller, no close substitutes.
Oligopoly: Few sellers, firms influence price (like airlines).
Monopolistic Competition: Many firms selling slightly differentiated products (like restaurants).
Example: The U.S. airline industry operates as an oligopoly since only a few large firms dominate.
Natural Monopoly: A monopoly that arises when high fixed costs make it more efficient to have one firm (like utilities).
Artificial Monopoly: A monopoly created by anti-competitive practices or government-granted rights.
Relevance: Natural monopolies justify government regulation, while artificial monopolies are targeted by antitrust policies.
Examples:
Natural Monopoly: Electric utilities (only one set of power lines is needed for efficiency).
Artificial Monopoly: Microsoft was accused of monopolistic behavior for controlling web browsers (Internet Explorer).
Definition: A single firm controls an entire market and faces no competition.
Relevance: Monopolies cause higher prices, lower output, and deadweight loss.
Example: Standard Oil was a monopoly until it was broken up under antitrust laws.
Government Regulation: Government regulates natural monopolies (like utilities) to ensure fair pricing.
Antitrust Policy: Break up or prevent monopolies (like the Sherman Antitrust Act).
Price Controls: Governments impose price ceilings to limit consumer costs.
Subsidies/Taxes: Subsidies encourage new entrants, and taxes can reduce market power.
Example: Sherman Antitrust Act led to the breakup of Standard Oil.
Definition: Laws and regulations designed to prevent monopolies and promote competition.
Relevance: Promotes competition, lowers prices, and increases consumer welfare.
Example: The Sherman Antitrust Act (1890) prohibits anti-competitive practices, price-fixing, and monopolization.
Definition: First U.S. federal law to prevent monopolies and anti-competitive behavior.
Relevance: Breaks up monopolies, encourages competition, and prevents abuse of power.
Example: Used to break up Standard Oil into multiple smaller companies.
Definition: Strengthened the Sherman Antitrust Act, outlawed price discrimination and mergers that reduce competition.
Relevance: Helps prevent large firms from consolidating market power.
Example: Used to block mergers between companies that would reduce competition (like AT&T/Time Warner merger).
Definition: Federal agency that enforces antitrust laws and promotes competition.
Relevance: Prevents anti-competitive mergers and stops deceptive business practices.
Example: The FTC sued Facebook for anti-competitive behavior regarding its acquisitions of Instagram and WhatsApp.
Definition: The economy as a whole, focusing on GDP, inflation, unemployment, and growth.
Relevance: Used to assess the health of the economy and guide government policies.
Example: The 2008 Great Recession was a major macroeconomic event that required stimulus spending and monetary policy intervention.
Definition: Government use of taxes and spending to influence the economy.
Relevance: Helps reduce unemployment, control inflation, and stimulate growth.
Example: COVID-19 stimulus checks were part of a fiscal policy response to increase demand during the pandemic.
Definition: Central bank policy to control money supply and interest rates.
Relevance: Used to stabilize inflation, promote growth, and reduce unemployment.
Example: The Federal Reserve lowers interest rates to stimulate the economy during recessions.
Price Stability: Control inflation to ensure stable purchasing power.
Full Employment: Keep unemployment at a natural rate.
Economic Growth: Ensure the economy grows steadily over time.
Relevance: Central banks use interest rate changes to meet these goals.
Open Market Operations: Buying/selling government securities to influence the money supply.
Discount Rate: The interest rate at which banks borrow from the Federal Reserve.
Reserve Requirement: The fraction of deposits banks must hold as reserves.
Relevance: The Federal Reserve uses these tools to manage inflation, employment, and liquidity.
Definition: Centralized but independent structure to manage U.S. monetary policy.
Main Components:
Board of Governors: 7 members appointed for 14-year terms.
Federal Open Market Committee (FOMC): Controls open market operations.
12 Regional Federal Reserve Banks: Implement policy at the local level.
Relevance: Ensures monetary policy is independent of political influence.
Definition: The Federal Reserve operates independently of direct political control.
Relevance: Prevents short-term political motives from influencing long-term monetary policy.
How: Governors serve staggered 14-year terms and cannot be fired by the president.
Example: During the COVID-19 pandemic, the Federal Reserve independently decided to lower interest rates to boost the economy.
Definition: The body that sets U.S. monetary policy by controlling open market operations.
Relevance: Directly influences interest rates, which affects the entire economy.
Example: If the FOMC lowers interest rates, borrowing increases and economic activity rises.
Definition: The Federal Reserve buys government bonds to increase the money supply.
Relevance: Used during financial crises to inject liquidity into the economy.
Example: QE was used after the 2008 financial crisis to stabilize the economy.
Definition: The Fed’s goal to promote maximum employment and price stability.
Relevance: Guides every decision the Federal Reserve makes.
Example: The Fed may lower interest rates to reduce unemployment but risks increasing inflation.
Definition: The percentage of deposits that banks must keep in reserve.
Relevance: Regulates how much banks can lend, controlling the money supply.
Example: During COVID-19, the reserve requirement was set to 0% to increase liquidity.
Definition: The buying and selling of government bonds by the Federal Reserve.
Relevance: Used to increase or decrease the money supply.
Example: To increase the money supply, the Fed buys bonds from banks, putting more money into circulation.
