Pedagogical Module — Teaching CDR Economics
Discussion questions, conceptual exercises, assessment tools, and key takeaways for course use
Core Conceptual Questions
- Q1. Why does the CDR model standardize all variables to [0,1]? What would happen if raw dollar values were used as regression inputs?
- Q2. The coefficient of C·D·R is negative (−1.21). Does this mean democracy hurts economic growth? Explain using the catalysis framework.
- Q3. Singapore has zero natural resources and high GDP; Nigeria has massive oil reserves and low GDP. How does CDR theory explain this? What would Nigeria need to change?
- Q4. Why is latitude a valid instrumental variable for purging endogenous capital stock from C? What assumption must hold, and how is it justified?
- Q5. If a country could instantaneously set C=D=R=1, what would CDR theory predict about GDP growth? Would this be sustainable?
Applied Exercises
- Exercise 1. Using the standardization formulas and the Table in §4, compute the CDR index for two countries of your choice. Compare your computed CDR to their reported GDPppp. (Try it: §4 has a live calculator with a country dropdown.)
- Exercise 2. Using the OLS equation ĝ = 1.53C + 0.14D + 0.23R − 1.21·C·D·R + 0.38N, compute the predicted GDPppp for a country with C=0.5, D=0.8, R=0.7, N=0.05, given Gmax = $83,066 and Gmin = $1,112.
- Exercise 3. A country's Rule of Law score improves from R=0.25 to R=0.60 (other variables held constant). Compute the marginal change in predicted g. Translate to dollars using the inverse transformation.
- Exercise 4. Calculate the entrepreneurship capital elasticity of g for a country with D=R=0.7 and reinvestment fraction f=0.1. Use the formula from P2 Appendix D / P4 §8.
- Exercise 5. Plot GDP growth rates for South Korea (1960–present) and explain the CDR interpretation: rapid growth during CDR adoption → convergence to ~1.8% as CDR matures.
Key Takeaways — Summary Card
- 1. GDP is governed by a scientific law: G = f(C, D, R) — global time invariant, parsimonious, R² = 83%.
- 2. The source of all wealth is human imagination and creativity (entrepreneurship capital), not natural resources or physical labor.
- 3. Capitalism, Democracy, and Rule of Law are the only policy-controllable determinants of GDP. Natural resources, geography, culture, population size are negligible.
- 4. Entrepreneurship capital (new ideas) contributes ~6× more to GDP than capital stock (old ideas). CDR contributes ~13× more than natural resources.
- 5. The theoretical steady-state growth rate is ~1.8% (= ¼e²). The theoretical maximum single-year growth is ~30%. Sustained growth above ~1.8% will eventually cause overheating.
- 6. Democracy creates friction (negative C·D·R interaction) — this is necessary and unavoidable in a democratic system. The optimal response is to accelerate democratic decision-making, not reduce democracy.
- 7. High CDR countries are where ideas go to fly. Low CDR countries are where ideas go to die.
Discussion Prompts for Advanced Seminars
- D1. The CDR model excludes government spending (its coefficient is statistically insignificant). How does this challenge both Keynesian and supply-side fiscal policy prescriptions?
- D2. CDR theory suggests wealth is unlimited because it originates in human imagination, which is unlimited (Simon, 1981). Evaluate this claim against resource-constrained growth frameworks.
- D3. "It is in the positive-sum self-interest of rich countries to help poor countries develop their CDR institutions." Evaluate this claim using the plus-sum capitalism framework from P3 §Discussion.
- D4. Property rights are described as essential to rule of law. De Soto (2000) found 90% of countries have no property rights for the common person. What are the specific barriers to implementing property rights in developing countries?
