• Chapter 1: What Is Economics? — Economics 101

  Economics is the study of how individuals, firms, and societies choose under scarcity — the universal condition that nothing is ever enough to satisfy all wants. This chapter unpacks the field’s basic vocabulary: factors of production, micro vs. macro, and the allocation problem that everything else builds on.

• Chapter 2: Trade-Offs and Opportunity Cost — Economics 101

  Every choice has a price tag, even when no money changes hands. This chapter introduces opportunity cost (the next-best alternative you gave up), marginal analysis (compare one more unit’s benefit to its cost), and the three core assumptions that classical economics quietly relies on.

• Chapter 3: The Emergence of Free Trade and the Importance of Comparative Advantage — Economics 101

  Why specialization plus exchange beats self-sufficiency — even when one party is better at producing everything. This chapter walks through mercantilism’s failure, Adam Smith’s case for free trade, and David Ricardo’s deeper insight: it is comparative advantage (lowest opportunity cost), not absolute advantage, that determines who should produce what.

• Chapter 4: International Trade and Trade Barriers — Economics 101

  Free trade creates wealth — but politics keeps building walls in front of it. This chapter covers why voluntary trade is positive-sum, the post-WWII institutions (GATT, WTO, IMF, World Bank) built to keep it open, and the three classic tools countries use to push back: tariffs, quotas, and embargoes.

• Chapter 5: Traditional, Command, and Market Economies — Economics 101

  Every society must answer three economic questions — what to produce, how to produce it, and for whom. The three pure answers are tradition (do as our ancestors did), command (a central authority decides), and markets (let individual buyers and sellers decide). Each has a track record. Pure forms barely exist; almost every modern economy is a hybrid.

• Chapter 6: Modern Economic Theories — Economics 101

  Classical economics assumes rational actors in efficient markets. Three modern theories — Minsky’s Financial Instability Hypothesis, New Growth Theory, and Kahneman & Tversky’s Prospect Theory — explain what classical models miss: why stable markets breed crashes, why human capital is the real engine of growth, and why people systematically reject equivalent gains framed as losses.

• Chapter 7: Information and Behavioral Economics — Economics 101

  Classical economics assumes perfect information and perfectly rational actors. The two new schools that replaced those assumptions — information economics (Stiglitz, Akerlof) and behavioral economics (Simon, Becker, Thaler) — explain how real markets cope with information gaps and human cognition, from used-car lemons to checkout-aisle candy.

• Chapter 8: Capitalism Versus Socialism — Economics 101

  Pure command and pure market systems don’t exist in the real world. What actually exists is hybrids — capitalism and socialism — that differ in how much the government owns, regulates, and redistributes. Behind the debate sit Adam Smith and Karl Marx, with rival views of human nature that still drive modern policy arguments.

• Chapter 9: Barter and the Development of Money — Economics 101

  Why barter doesn’t scale, what jobs money actually does, and how currency evolved from commodity to representative paper to inconvertible fiat — with the gold standard as the pivotal compromise in the middle.

• Chapter 10: Inconvertible Fiat Explored — Economics 101

  Modern money is backed by nothing but faith — that’s a feature, not a bug. How inconvertible fiat lets the money supply grow with the economy, why inflation is the price of that flexibility, and what the Fed’s M1 and M2 measures actually track.

• Chapter 11: The Time Value of Money and Interest Rates — Economics 101

  A dollar today is worth more than a dollar tomorrow — and that simple fact builds every interest rate you’ll ever encounter. The five-block stack: real rate, expected inflation, default risk, liquidity, and maturity premiums.

• Chapter 12: A Brief History of Banking — Economics 101

  Banks aren’t vaults — they’re money factories. How banking evolved from Mesopotamian grain receipts to fractional-reserve goldsmiths to the modern system, and the surprising accounting trick by which a single deposit turns into many.

• Chapter 13: Banks as a System — Regulation and Deregulation — Economics 101

  Banks don’t operate alone — they lend to each other overnight, share contagion when confidence fails, and live or die by a regulatory framework that has swung between tight and loose for 160 years. How the fed funds market, bank runs, and the Dodd-Frank pendulum fit together.

• Chapter 14: Supply and Demand: Markets — Economics 101

  What a market actually is, the four conditions for perfect competition, and why those conditions matter even though real markets never fully meet them.

• Chapter 15: Supply and Demand: Consumer Behavior — Economics 101

  Why consumers buy what they buy — utility maximization under a budget constraint, diminishing returns, the three drivers of the law of demand, and price elasticity.

• Chapter 16: Supply and Demand: A Price Is Born — Economics 101

  How supply meets demand to produce a market-clearing price — and what surpluses, shortages, and the law of supply tell you when the price is wrong.

• Chapter 17: Changes in Supply and Demand — Economics 101

  What shifts the supply or demand curve — input prices, nature, expectations, tastes, incomes, substitutes, complements — and how each shift moves price and quantity.

• Chapter 18: Accounting Versus Economics — Economics 101

  Why the same business can be profitable to an accountant and unprofitable to an economist — and why opportunity cost is the missing entry that decides whether resources are in their best use.

• Chapter 19: The Production Function — Economics 101

  How a firm converts inputs into output — the three stages of returns (increasing, diminishing, negative), fixed vs variable costs, and the marginal-cost-equals-marginal-revenue rule that decides how much to produce.

• Chapter 20: Perfect Competition in the Short and Long Run — Economics 101

  What perfect competition is, why it’s a thought experiment more than a reality, how entry and exit drive economic profit to zero in the long run, and how real markets sit on a continuum from perfect competition to monopoly.

• Chapter 21: Oligopolies and Imperfectly Competitive Markets — Economics 101

  Most industries you actually interact with are oligopolies — a handful of large firms whose decisions are interdependent. Why that matters, how regulators measure it, and what it costs consumers.

• Chapter 22: Collusion and Cartels — Economics 101

  Why oligopolists are tempted to coordinate prices, why coordination is illegal in the US, and why cartels — even OPEC — always teeter between cooperation and cheating.

• Chapter 23: Game Theory — Economics 101

  How to reason about decisions when the right answer depends on what someone else is about to do. The Prisoner’s Dilemma, dominant strategies, and why tit-for-tat is how oligopolists quietly cooperate.

• Chapter 24: Pricing Behaviors — Economics 101

  Price leadership, price wars, product differentiation, and price discrimination — the four pricing strategies that emerge when firms have market power but can’t legally collude.

• Chapter 25: Monopoly — The Good, the Bad, and the Ugly — Economics 101

  Not all monopolies are evil. Natural monopolies, patent monopolies, and government monopolies exist for defensible reasons. Unregulated monopolies are the problem — De Beers is the textbook ugly.

• Chapter 26: Government in the Marketplace — Price Ceilings and Price Floors — Economics 101

  Legal caps on prices create shortages; legal floors create surpluses. The reason isn’t politics — it’s the law of supply and demand. Rent control and minimum wage are the textbook cases.

• Chapter 27: Government in the Marketplace — Taxes and Subsidies — Economics 101

  Taxes raise costs and shrink supply; subsidies lower costs and expand it. Both are precision tools for shaping behavior — and both come with side effects, distortions, and the occasional black market.

• Chapter 28: Market Failures — Economics 101

  Public goods, positive and negative externalities, and black markets — the four canonical situations where free markets produce socially suboptimal outcomes and government intervention has a defensible case.

• Chapter 29: Financial Markets and Loanable Funds Theory — Economics 101

  How savers and borrowers meet in the loanable funds market to set the real interest rate — and why Keynes’s liquidity preference theory adds a second, faster channel for short-term rates.

• Chapter 30: The Money Market — Economics 101

  The market for short-term credit — commercial paper, Treasury bills, and federal funds — where firms, governments, and banks borrow for less than a year and the Fed plants its policy lever.

• Chapter 31: The Bond Market — Economics 101

  How governments and firms borrow for the long term, why the 10-year Treasury is the benchmark for almost every other rate, and the four risks every bondholder is implicitly paid to bear.

• Chapter 32: The Stock Market — Economics 101

  Stocks are partial ownership of firms, not loans. How IPOs create new shares, why nearly all daily trading happens in the secondary market, and why mutual funds and ETFs democratized equity investing.

• Chapter 33: Foreign Exchange and Foreign Trade — Economics 101

  Exchange rates are the price of one currency in another. How interest rates, inflation, and trade flows move them — and why countries choose to fix, float, or share a currency.

• Chapter 34: Cryptocurrency — Economics 101

  Digital assets that act like money but aren’t legal tender. How blockchain settles a transaction without a central authority, the trade-offs vs. fiat currency, and the volatility and tax traps that come with it.

• Chapter 35: Economic Sectors — Economics 101

  The circular flow model — how households, firms, government, and the foreign sector exchange goods, factors, and money — plus the financial sector that sits in the middle of every transaction.

• Chapter 36: The Gross Domestic Product — Economics 101

  GDP measures the total value of final goods and services produced inside a country in a year — equivalently, total spending on that output and total income earned from it. What it counts, what it excludes, and why.

• Chapter 37: GDP — Private Spending and Investment — Economics 101

  Inside the C and I components of GDP: what drives household consumption, how disposable income, wealth, interest rates, and expectations move it, and why inventory build-up is an early recession warning.

• Chapter 38: GDP — Government Spending and Exports — Economics 101

  The G and (X − M) components of GDP: what government counts as spending, why transfer payments don’t, and how exchange rates and interest rates push net exports up or down.

• Chapter 39: Approaches to GDP — Economics 101

  Three different ways to measure GDP — expenditure, income, and production — that should give the same answer. Plus the crucial distinction between nominal and real GDP and the GDP deflator.

• Chapter 40: Real GDP Changes and the Business Cycle — Economics 101

  The business cycle — alternating expansions and contractions around a long-run growth trend — its four classic stages, and the competing theories (monetarist, Keynesian, Real Business Cycle) of what causes it.

• Chapter 41: What GDP Doesn’t Tell Us — Economics 101

  The structural blind spots of GDP — unpaid labor, income distribution, environmental cost, leisure, and wellbeing — and the alternative measures (GPI, HDI, Happy Planet Index, green GDP) that try to patch them.

• Chapter 42: Key Economic Indicators — Economics 101

  The leading-coincident-lagging taxonomy of economic indicators: which numbers tell you where the economy is heading, where it is now, and where it has just been — plus a tour of the offbeat indicators traders actually watch.

• Chapter 43: The US Deficit and National Debt — Economics 101

  Why deficit and debt are different concepts, how the US accumulates and services its debt, what ‘full faith and credit’ means, and how the debt-to-GDP ratio reframes the headline numbers.

• Chapter 44: Unemployment Defined — Economics 101

  Unemployment is not simply ‘not working’ — it has a precise definition, three qualitatively different types, and a measurable cost to individuals and the whole economy. Understanding these distinctions explains why policymakers respond differently to different unemployment episodes.

• Chapter 45: Inflation Defined — Economics 101

  Inflation is a general rise in the price level — or equivalently, a fall in money’s purchasing power. It has two distinct causes, three measurement tools, and one target rate (2%) that central banks treat as a cornerstone of stable growth.

• Chapter 46: Inflation: Winners and Losers — Economics 101

  Unexpected inflation is a hidden wealth transfer: it enriches borrowers at lenders’ expense, helps producers before workers catch up, and devastates savers and people on fixed incomes. Understanding who wins and who loses explains why inflation persists and why its distribution matters as much as its level.

• Chapter 47: Disinflation and Deflation — Economics 101

  Disinflation — a falling inflation rate — is generally beneficial, bringing lower interest rates and stable expectations. Deflation — a falling price level — is a trap: it induces consumers and firms to delay spending, collapses demand, and defeats the central bank’s primary tool once interest rates hit zero.

• Chapter 48: Aggregate Demand and Aggregate Supply — Economics 101

  Aggregate demand (AD) and aggregate supply (AS) are the macroeconomic counterparts to the individual market’s supply-and-demand model. Together they explain why economies expand and contract, why unemployment and inflation move the way they do, and why the short run and long run behave so differently.

• Chapter 49: Macroeconomic Equilibrium — Economics 101

  Macroeconomic equilibrium is where aggregate demand meets aggregate supply. Short-run equilibria can sit above or below the economy’s long-run potential — creating inflationary or recessionary gaps. Classical economists trust markets to close those gaps automatically; Keynesians don’t.

• Chapter 50: The Keynesian View and Fiscal Policy — Economics 101

  Keynes challenged classical economics by showing that recessions can persist because wages are sticky and saving doesn’t automatically become investment. His remedy — government spending during recessions — works through a multiplier effect. But the inflation-unemployment trade-off he implied breaks down when inflation expectations shift.

• Chapter 51: The Federal Reserve System — Economics 101

  The Federal Reserve is America’s central bank — a decentralized, public-private hybrid created in 1913 to provide a lender of last resort, manage the money supply, and keep the financial system stable. This chapter traces the Fed’s origins, structure, and the FOMC’s role in setting monetary policy.

• Chapter 52: US and Global Economic Institutions — Economics 101

  The IRS, US Treasury, World Bank, IMF, and WTO are the institutional scaffolding that keeps money flowing, taxes collected, global trade rules enforced, and developing economies supported. This chapter maps what each institution does and why they collectively matter for economic stability.

• Chapter 53: Monetary Policy — Economics 101

  Monetary policy is the Fed’s toolkit for steering the economy: open market operations, the discount rate, and reserve requirements each adjust the money supply and interest rates, shifting aggregate demand and — through it — GDP, unemployment, and inflation.

• Chapter 54: Supply-Side Economics — Economics 101

  Supply-side economics emerged in the 1970s as a direct response to stagflation — the failure of Keynesian demand management to handle simultaneous high unemployment and high inflation. It argues that tax cuts, deregulation, and reduced government interference unlock productive capacity and grow the economy from the supply side.

• Chapter 55: Economic Growth — Economics 101

  Economic growth — a sustained increase in real GDP per capita over time — is the mechanism behind rising living standards, longer lives, and greater material abundance. This chapter examines what growth means, how it is measured, and the dual reality that it brings both benefits and costs.

• Chapter 56: Conditions for Economic Growth — Economics 101

  Economic growth requires four compounding inputs: human capital (education and skills), physical capital (tools and infrastructure), research and development (innovation), and rule of law (property rights and fair enforcement). This chapter examines each condition and why its absence stalls growth even when natural resources are abundant.

• Chapter 57: How Economic Policy Affects Growth — Economics 101

  Government policy shapes long-run economic growth through three channels: interest rate policy (monetary), fiscal balance (spending vs. deficits), and tax structure (work and investment incentives). This chapter shows how each lever works and where getting it wrong stunts capital accumulation and growth.

• Chapter 58: The Great Depression Meets the Great Recession — Economics 101

  Two of America’s worst economic catastrophes share a common anatomy: deregulation, easy credit, asset bubbles, and cascading failures. This chapter traces the roots of the Great Recession through securitization and the CDO machine, and connects the 2008 meltdown to lessons—and failures—from the Great Depression.

• Chapter 59: The Collapse of Investment Banking — Economics 101

  Misaligned incentives, fraudulently rated CDOs, and an unhedged insurance market drove Bear Stearns and Lehman Brothers to the brink — and beyond. This chapter explains how the principal-agent problem, credit default swaps, and moral hazard combined to trigger the 2008 global credit freeze.

• Chapter 60: Fiscal Policy Under Fire — Economics 101

  When the 2008 financial crisis disabled the Fed’s conventional tools and exhausted the government’s fiscal space, policymakers had to improvise. This chapter examines quantitative easing, TARP, the Recovery Act, and the contentious fiscal experiments that followed — from the Trump tax cuts to COVID relief programs.

• Chapter 61: The Environment and the Economy — Economics 101

  Environmental protection and economic growth are usually framed as opposing forces — but economics offers tools to achieve both simultaneously. This final chapter explains how price incentives, property rights, cap-and-trade systems, carbon markets, and the Coase theorem can align the interests of firms and the environment more effectively than blunt regulation alone.

• Economics 101 — Economics 101

  A chapter-by-chapter synthesis of Alfred Mill & Michele Cagan’s Economics 101 — from scarcity and trade-offs through markets, money, GDP, inflation, monetary and fiscal policy.
