5⃣ Goals/Principles of Economic Policy

  • 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.


6⃣ Pareto Efficiency

  • 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.


7⃣ Role of the State

  • 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.


8⃣ Efficiency-Equity Tradeoff

  • 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.


📘 FAIRNESS AND INEQUALITY


9⃣ Rawls' Veil of Ignorance

  • 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).


🔟 Rawls' Maxi-Min Principle

  • Definition: Maximize the welfare of the least-advantaged members of society.

  • Relevance: Supports policies that reduce inequality.

  • Example: Progressive taxation benefits low-income households.


1⃣1⃣ Nozick's Libertarian Principle

  • Definition: Emphasizes minimal government intervention and protection of property rights.

  • Relevance: Opposes redistributive taxation and supports a "minimal state."

  • 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.



📘 INCOME, INEQUALITY, AND PIKETTY & SAEZ


1⃣ Income (Labor Income + Capital Income)

  • 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.


2⃣ Inequality in the U.S.

  • 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.


3⃣ Piketty & Saez Main Idea

  • 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.


📘 REGULATIONS AND GOVERNMENT INTERVENTION


4⃣ Regulations

  • 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.


5⃣ Waves of Regulation (Cohen's Key Features)

  • Definition: Different periods of intense regulatory action in U.S. history.

    • 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.


📘 MARKET FAILURES AND PUBLIC GOODS


6⃣ Market Failure

  • Definition: When the market fails to allocate resources efficiently.

  • Causes: Monopolies, externalities, and public goods.

  • Relevance: Justifies government intervention in the market.

7⃣ Externalities

  • 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.


8⃣ Cap-and-Trade (RGGI)

  • 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.


9⃣ Public Goods

  • 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.


🔟 Public vs Private Prisons

  • 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.



📘 INCOMPLETE INFORMATION AND HEALTHCARE IN THE U.S.


1⃣ Adverse Selection

  • 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.


2⃣ Moral Hazard

  • 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.


3⃣ Deductible

  • 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.


📘 FEATURES OF HEALTHCARE MARKETS


4⃣ Features of Healthcare Markets

  • 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.


📘 MEDICARE, MEDICAID, AND THE ACA


5⃣ Medicare

  • 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.


8⃣ Key Features of the ACA

  • 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.


📘 IMPERFECT COMPETITION


1⃣ Imperfect Competition

  • 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.


2⃣ Types of Monopolies

  • 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).


3⃣ Monopoly

  • 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.


4⃣ Solutions to Imperfect Competition

  • 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.


📘 ANTITRUST POLICY


5⃣ Antitrust Policy

  • 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.


6⃣ Sherman Antitrust Act (1890)

  • 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.


7⃣ Clayton Antitrust Act (1914)

  • 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).


8⃣ Federal Trade Commission (FTC)

  • 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.
