Modern Economic Growth

HardEconomics21 chapters

A deep dive into the root causes of national wealth and global inequality. Uncover the mechanics of capital and innovation while exploring how history, geography, and political institutions decide the economic fate of nations.

What This Course Covers

Modern Economic Growth is structured into 21 chapters that build on each other progressively:

Chapter 1: The World Income Distribution and the Great Divergence
Chapter 2: The Solow Growth Model
Chapter 3: Empirics of Solow: Growth and Development Accounting
Chapter 4: Foundations of Neoclassical Growth: Preferences and Optimization
Chapter 5: The Neoclassical Growth Model and Optimal Control
Chapter 6: Growth with Overlapping Generations
Chapter 7: Human Capital and the Ben Porath Model
Chapter 8: Population Growth, Fertility, and the Demographic Transition
Chapter 9: First-Generation Endogenous Growth: The AK Model
Chapter 10: Expanding Varieties: Innovation through Product Proliferation
Chapter 11: Competitive Innovations (Schumpeterian Growth)
Chapter 12: Directed Technological Change
Chapter 13: Stochastic Growth: Business Cycles and Uncertainty
Chapter 14: Growth with Incomplete Markets
Chapter 15: Technology Diffusion and the Advantage of Backwardness
Chapter 16: International Trade: Specialization and Comparative Advantage
Chapter 17: Structural Change and Economic Growth
Chapter 18: Poverty Traps: Multiple Equilibria and Financial Frictions
Chapter 19: Fundamental Determinants: Geography vs. Institutions
Chapter 20: Political Economy of Growth and Institutions
Chapter 21: Synthesis and the Causes of Growth

Each chapter combines interactive AI tutoring with hands-on examples. After you learn the material, Lambdio's spaced repetition algorithm schedules review sessions at optimal intervals — so you retain concepts and techniques long-term.

How to Study Modern Economic Growth on Lambdio

Lambdio's AI-powered platform adapts to how Economics courses are best learned. Here's our recommended approach:

Learning Mode
Standard Mode — for first-time learning of each chapter
Review Modes
Standard, Quiz — for spaced repetition reviews
Learning Priority
High Priority — controls how often the algorithm schedules reviews

Modern Economic Growth is a quantitatively demanding course combining dynamic optimization, differential equations, and formal growth models — from Solow to Ramsey to endogenous innovation frameworks. Standard Mode is the ideal learning approach because the AI tutor can explain each model's structure step by step, derive key equilibrium conditions, and illustrate the intuition behind mathematical results. Socratic Mode is less appropriate for a subject where understanding the mechanics of the Euler equation, the Maximum Principle, or the convergence regression framework requires clear exposition rather than discovery through questioning. The Hard difficulty and dense theoretical nature of the material make High priority the right default — the spaced repetition algorithm will schedule frequent reviews to consolidate complex model mechanics, steady-state analyses, and the empirical relationships that connect theory to data. For rapid reinforcement of model predictions and key economic mechanisms, pairing Standard Mode with Quiz Mode during review sessions provides an efficient path to long-term mastery.

Q4: What does the Modified Golden Rule in the Ramsey-Cass-Koopmans model state?
Q5: In the expanding varieties model, why does the decentralized equilibrium produce lower growth than the social optimum?
Q6: The demographic transition explains why:
Q7: Under what condition is an OLG economy dynamically inefficient?
Q8: In directed technological change, which two competing effects determine the direction of R&D?

What You'll Be Able to Do After This Course

  • Analyze cross-country income differences using the Solow growth model and its augmented forms with human capital
  • Solve dynamic optimization problems in continuous and discrete time using optimal control and dynamic programming
  • Compare and contrast the mechanisms of the Solow, Ramsey-Cass-Koopmans, OLG, and endogenous growth models
  • Evaluate the predictions of AK, expanding varieties, and Schumpeterian growth models and their empirical validity
  • Explain how the direction of technological change responds to factor supplies and affects wage inequality
  • Understand the interaction between incomplete markets, financial development, precautionary savings, and wealth inequality
  • Assess the roles of innovation versus technology adoption in cross-country growth differences
  • Critically evaluate the geography versus institutions debate as fundamental causes of the Great Divergence
  • Apply political economy reasoning to explain the persistence of inefficient institutions and barriers to growth
  • Synthesize the mechanics, incentives, and constraints framework into a coherent understanding of modern economic growth
