See how trade, specialization, money, and prices help people coordinate without one person planning everything. You connect simple exchanges to wages, rent, interest, and profits.

Graphs, tables, equations, and plain-language assumptions let economists simplify messy life without ignoring it. You practice reading slopes, curves, changes, and simple models.

Follow the field from classical political economy through marginalism, Marx, Keynes, monetarism, game theory, econometrics, behavioral economics, and modern data work. The goal is to see why today’s tools and debates took the shape they did.

Economic arguments depend on measurements like prices, wages, employment, output, and inequality. You practice reading official data, indexes, averages, growth rates, and real versus nominal values.

Households and buyers face budgets, preferences, prices, and trade-offs. You build demand from individual choices and see why income, substitutes, complements, and expectations shift it.

Firms combine labor, capital, materials, and technology to produce goods and services. You connect production decisions to fixed cost, variable cost, marginal cost, and supply.

Supply and demand come together to explain prices, quantities, shortages, and surpluses. You practice predicting what happens when taxes, tastes, technology, or costs change.

Elasticity measures how strongly people or firms respond when price, income, or another condition changes. You use it to reason about revenue, taxes, addiction, housing, and fuel demand.

Markets create gains from trade, but those gains are not always shared equally. This chapter builds consumer surplus, producer surplus, efficiency, deadweight loss, and distributional judgment.

Some problems cannot be solved by ordinary market exchange alone. You handle externalities, missing markets, transaction costs, and the policy tools used to improve outcomes.

Clean air, public safety, fisheries, roads, and knowledge create coordination problems. You study free riding, congestion, common resources, clubs, and the role of collective rules.

Competition changes when firms can influence prices instead of taking them as given. You work through monopoly, price discrimination, oligopoly, entry barriers, and market concentration.

Many economic choices depend on what others are likely to do. You use game trees, payoff tables, Nash equilibrium, credible threats, cooperation, and repeated interaction.

Insurance, lending, employment, and used-car markets all depend on hidden information and risk. You study adverse selection, moral hazard, signaling, screening, and contracts.

Wages and employment reflect skills, bargaining power, discrimination, institutions, and changing demand for work. You connect labor supply and demand to minimum wages, unions, migration, and automation.

Poverty and inequality are measured in several ways, and each measure answers a different question. You use income, wealth, mobility, consumption, poverty lines, and inequality indexes to compare real conditions.

People do not always act like perfectly calculating machines. This chapter covers bias, framing, loss aversion, nudges, lab experiments, field experiments, and when behavioral findings help policy or business decisions.

Macroeconomics starts by measuring production, income, spending, employment, and prices across a whole economy. You connect GDP, national income, inflation indexes, unemployment, and productivity.

Long-run prosperity depends on productivity, capital, human skills, institutions, innovation, and population change. You compare growth accounting, convergence, and why living standards differ across countries.

Saving and investment move resources from today to tomorrow. You study interest rates, financial intermediaries, capital markets, risk sharing, and why financial breakdowns can damage the real economy.

Money makes exchange easier, but banking also creates credit and fragility. You cover deposits, reserves, bank runs, central banks, payment systems, and the money supply.

Economies move through expansions, slowdowns, recessions, and recoveries. You use aggregate demand and aggregate supply to reason about shocks, idle resources, and short-run stabilization.

Inflation and unemployment shape daily life and political choices. You work with expectations, the Phillips curve, wage-price dynamics, credibility, and the costs of disinflation.

Government budgets affect demand, incentives, public investment, and debt. You study spending, taxes, deficits, automatic stabilizers, multipliers, debt sustainability, and fiscal rules.

Central banks influence interest rates, credit, expectations, and inflation. You compare conventional rate policy, forward guidance, quantitative easing, lender-of-last-resort actions, and central bank independence.

Countries trade goods, services, assets, ideas, and labor across borders. You connect comparative advantage, trade gains, tariffs, quotas, capital flows, and global imbalances.

Exchange rates affect imports, exports, inflation, debt, and financial stability. You study floating and fixed rates, currency crises, balance of payments accounts, and reserve currencies.

Economists use probability and statistics to separate patterns from noise. You practice distributions, sampling, confidence intervals, hypothesis tests, correlation, and common measurement mistakes.

Regression helps estimate relationships while holding other factors constant. You build intuition for coefficients, controls, omitted variables, standard errors, dummy variables, and model fit.

Many economic questions ask what would have happened under a different choice or policy. You work with counterfactuals, selection bias, identification, treatment effects, and causal diagrams.

Real evidence often comes from policy changes, lotteries, thresholds, timing, or accidents of history. You use randomized trials, difference-in-differences, regression discontinuity, instrumental variables, and event studies.

Economic data often arrives over time, with trends, cycles, seasonality, and sudden breaks. You practice forecasting, nowcasting, autocorrelation, lagged effects, and uncertainty bands.

Current economic work depends on clean data, transparent code, and results others can check. You build a small workflow with data cleaning, documentation, version control, notebooks, tables, charts, and a replication package.

Follow a real policy question from problem framing to recommendation. You define the decision, gather evidence, compare options, estimate trade-offs, handle uncertainty, and write a clear memo for a nontechnical audience.

Taxes raise revenue and change behavior at the same time. You study income taxes, payroll taxes, consumption taxes, corporate taxes, tax incidence, efficiency costs, and fairness.

Modern governments insure people against risks that private markets may not handle well. You examine unemployment insurance, pensions, disability support, food assistance, cash transfers, and work incentives.

Health and education shape productivity, opportunity, and public budgets. You study insurance markets, provider incentives, human capital, school quality, returns to education, and cost-effectiveness.

Where people live affects wages, commuting, schools, segregation, productivity, and wealth. You analyze housing supply, zoning, rent control, agglomeration, transportation, and local public finance.

Trade changes prices, jobs, firms, and political coalitions. You work with comparative advantage, trade models, offshoring, global value chains, trade agreements, and adjustment costs.

Poor countries face linked problems in credit, health, education, infrastructure, institutions, and risk. You study poverty traps, structural transformation, agriculture, migration, aid, microfinance, and randomized development policy.

Laws, political power, trust, corruption, and state capacity shape economic outcomes. You connect institutions to growth, markets, public goods, regulation, conflict, and reform.

Financial prices summarize expectations about risk and future payoffs. You study bonds, stocks, diversification, asset pricing, bubbles, leverage, derivatives, and financial regulation.

Competition policy uses economics to judge mergers, monopolization, collusion, and consumer harm. You practice market definition, concentration measures, pricing evidence, entry analysis, and remedies.

Pollution creates costs that markets often miss. You compare standards, taxes, cap-and-trade, permits, liability, valuation of damages, and cost-benefit analysis.

Climate change turns emissions, risk, technology, finance, and fairness into one economic problem. You study carbon pricing, integrated assessment models, adaptation, transition risk, stranded assets, and climate justice.

Digital platforms depend on network effects, data, ranking systems, and two-sided markets. You analyze search, social media, app stores, gig platforms, privacy, lock-in, and platform regulation.

Some markets work only when rules are carefully designed. You study auctions, matching, school choice, spectrum sales, kidney exchange, ad markets, and algorithmic allocation.

Digital payments and crypto systems changed debates about trust, money, regulation, and financial access. You compare payment rails, stablecoins, cryptocurrencies, decentralized finance, central bank digital currencies, fraud, and systemic risk.

Large datasets and machine learning now support forecasting, pricing, evaluation, and research. You use prediction versus causation, text data, satellite data, model validation, algorithmic bias, and AI-assisted economic work.

Recent shocks made supply networks central to inflation, business planning, and national security. You analyze inventories, bottlenecks, shipping, input-output links, reshoring, resilience, and the cost of redundancy.

Remote work and app-based work changed job matching, supervision, cities, and bargaining. You study gig contracts, worker classification, flexible schedules, monopsony power, productivity evidence, and policy trade-offs.

Economic advice can affect jobs, prices, budgets, and rights. You practice stating assumptions, separating evidence from values, showing distributional effects, communicating uncertainty, and avoiding overclaiming.

Close the course by mapping economics as a living field. You identify roles and specialties, graduate and non-graduate paths, portfolio projects, data skills, policy and research organizations, certifications where useful, and habits for staying current.
