🔹 Lesson 1: The Capitalist Revolution

Overview: This lesson explores the dramatic transformation in human living standards over the last millennium, characterized by "History's Hockey Stick." It examines how the permanent technological revolution and the emergence of capitalism—defined by private property, markets, and firms—reshaped global economies. Students will learn to measure these changes using GDP and the Gini coefficient while evaluating the subsequent impacts on environmental sustainability and social inequality.

Learning Outcomes:

• Define and distinguish between GDP, Disposable Income, and Purchasing Power Parity (PPP).
• Analyze the three core institutions of capitalism and how they interact to drive economic growth.
• Interpret economic inequality using the Lorenz curve and the Gini coefficient.

🔹 Lesson 2: Technological Change, Population and Economic Growth

Overview: This lesson explores why living standards remained stagnant for centuries and how the transition to sustained economic growth finally occurred. By using economic models—specifically production functions, isocost lines, and innovation rents—we analyze the Malthusian Trap and the unique conditions of the British Industrial Revolution that allowed humanity to escape the cycle of poverty through a permanent technological revolution.

Learning Outcomes:

• Explain the mechanics of the Malthusian Trap using the concepts of diminishing average product of labour and subsistence levels.
• Apply isocost lines and relative prices to model how firms choose technologies to maximize innovation rents.
• Evaluate how the British Industrial Revolution's unique price environment (high wages, low energy costs) incentivized the shift to capital-intensive production.

🔹 Lesson 3: Scarcity, Work, and Well-being

Overview: This lesson explores how individuals make optimal choices when faced with scarcity, specifically focusing on the trade-off between free time and consumption (or grades). Students will learn to model production possibilities through the feasible frontier and individual preferences through indifference curves. By the end of this unit, students will apply the concepts of income and substitution effects to explain historical shifts and international differences in working hours.

Learning Outcomes:

• Define and calculate the Marginal Product of Labour, Marginal Rate of Substitution (MRS), and Marginal Rate of Transformation (MRT).
• Illustrate how individual preferences and technological constraints interact to solve a constrained choice problem.
• Analyze how wage changes impact labor supply by decomposing the resulting shift into income and substitution effects.

🔹 Lesson 4: Social Interactions

Overview: This lesson introduces the fundamentals of strategic interaction through the lens of Game Theory. It explores why individual pursuit of self-interest can lead to "social dilemmas"—outcomes where everyone is worse off—and examines how social preferences (like altruism and reciprocity), social norms, and institutional rules (like peer punishment) can resolve these conflicts. The material culminates in applying these theories to global challenges, specifically climate change.

Learning Outcomes:

• Define and identify social dilemmas, specifically the Tragedy of the Commons and the Prisoner's Dilemma.
• Construct and interpret payoff matrices to identify dominant strategies and Nash equilibria.
• Analyze how social preferences and peer punishment facilitate cooperation in public goods experiments.

🔹 Lesson 5: Property and Power: Mutual Gains and Conflict

Overview: This lesson explores how economic outcomes are determined by the interaction of institutions, technology, and biology. It introduces the criteria of Pareto efficiency and fairness to evaluate these outcomes, while analyzing how bargaining power dictates the distribution of economic rents and surplus. Students will learn to visualize these dynamics through feasibility frontiers, biological survival constraints, the Pareto efficiency curve, and inequality measures like the Gini coefficient and Lorenz curve.

Learning Outcomes:

• Define institutions as "the rules of the game" and analyze how they influence bargaining power and economic outcomes.
• Evaluate economic allocations using the criteria of Pareto efficiency and both substantive and procedural judgments of fairness.
• Distinguish between technically feasible allocations and those limited by biological survival constraints or voluntary exchange (economic feasibility).

🔹 Lesson 6: The Firm: Owners, Managers, and Employees

Overview: This lesson explores the internal dynamics of the firm as a central actor in the capitalist economy. It contrasts the authority-based coordination within firms against the price-based coordination of markets, highlighting the "Principal-Agent" challenges arising from the separation of ownership and control. Students will analyze the labor discipline model to understand how incomplete contracts and employment rents are used by employers to motivate effort and maximize profits.

Learning Outcomes:

• Distinguish between the coordination mechanisms of firms and markets.
• Analyze the impact of incomplete contracts and the resulting employment rents on worker motivation and the cost of job loss.
• Model the labor discipline game using best response curves and isoprofit curves to determine profit-maximizing wages.

🔹 Lesson 7: The Firm and its Customers

Overview: This lesson explores how firms with market power decide on price and output to maximize profits. It examines the interplay between a firm's internal cost structure and external market constraints like demand curves and consumer willingness to pay. Students will analyze how these decisions affect market efficiency, the distribution of gains from trade through consumer and producer surplus, and how the elasticity of demand influences markups and government policy.

Learning Outcomes:

• Analyze Cost Dynamics by distinguishing between total, average, and marginal costs and explaining how economies of scale influence firm growth.
• Determine Profit Maximization by using demand curves and isoprofit curves to identify the optimal price and quantity.
• Evaluate Market Welfare by quantifying gains from trade using consumer and producer surplus and identifying deadweight loss.

🔹 Lesson 8: Supply and Demand: Price-taking and Competitive Markets

Overview: This lesson explores how prices function as messages of scarcity within competitive markets where buyers and sellers act as price-takers. It details the mechanics of market equilibrium through Marshall’s model, the realization of Pareto efficiency through gains from trade, and the long-term dynamics of firm entry and exit. Additionally, it examines how external interventions, such as taxes, create deadweight loss and redistribute welfare.

Learning Outcomes:

• Define and identify price-taking behavior in buyers and sellers.
• Construct and interpret market supply and demand curves using Willingness to Pay (WTP) and Willingness to Accept (WTA).
• Evaluate market outcomes based on Pareto efficiency and the impact of taxation on total surplus.

🔹 Lesson 9: Rent-seeking, Price-setting, and Market Dynamics

Overview: This lesson explores how markets transition from disequilibrium to equilibrium through the rent-seeking behavior of individuals and firms. It examines why some markets do not "clear," resulting in unemployment or queues, and analyzes the mechanics of financial markets where speculation can drive prices far from their fundamental values. Finally, the lesson distinguishes between stationary rents that persist in equilibrium and dynamic rents that drive economic change.

Learning Outcomes:

• Explain how rent-seeking behavior acts as the moving force behind market equilibration following an exogenous shock.
• Analyze the Labor Market Model using wage and profit curves to demonstrate why unemployment is a characteristic of Nash equilibrium.
• Identify the conditions that lead to non-clearing markets, asset price bubbles, and the role of feedback loops in financial speculation.

🔹 Lesson 10: Markets, Efficiency, and Public Policy

Overview: This lesson explores why markets sometimes fail to allocate resources efficiently, resulting in Pareto-inefficient outcomes. It examines the impact of externalities where private decisions impose uncompensated costs or benefits on others, and analyzes how private bargaining or government policy can remedy these failures. Additionally, the lesson covers the challenges of public goods, innovation, and asymmetric information.

Learning Outcomes:

• Define and identify market failures arising from negative and positive external effects.
• Evaluate the effectiveness of Coasian bargaining versus Pigouvian taxes in achieving Pareto efficiency.
• Categorize goods using the dimensions of rivalry and excludability and explain why non-rivalry leads to market failure.

🔹 Lesson 11: Banks, Money, and the Credit Market

Overview: This lesson explores the fundamental mechanics of how individuals and institutions move purchasing power through time. It defines the distinctions between money, wealth, and income, and models how individual preferences for consumption smoothing drive the credit market.

• Evaluate how household wealth, credit constraints, and business confidence drive fluctuations in private spending.
• Assess the effectiveness of fiscal policy tools, including automatic stabilizers and the impact of austerity during recessions.

🔹 Lesson 14: Inflation, Unemployment, and Monetary Policy

Overview: This lesson explores the dynamic relationship between inflation and unemployment, centered on the role of the labor market and central bank intervention. It examines how conflicting claims on output lead to the wage-price spiral and the Phillips Curve, the impact of supply shocks, and the mechanisms of modern monetary policy—including inflation targeting and Quantitative Easing.

Learning Outcomes:

• Analyze the costs of inflation and deflation, specifically their effects on real interest rates and wealth redistribution.
• Explain the origins of inflation through the bargaining gap and the resulting wage-price spiral.
• Model the shift in the Phillips Curve driven by changes in inflation expectations and supply-side shocks.

🔹 Lesson 15: Technological Progress, Employment, and Living Standards in the Long Run

Overview: This lesson explores how technological progress and "creative destruction" drive long-run improvements in living standards without necessarily increasing unemployment. It introduces the labor market's long-run equilibrium through the interaction of the profit curve and wage curve, and examines how different institutional frameworks determine whether a country becomes an economic star or a laggard.
