  1. The future of the Korean Economy Sehwa Lee, Taizo Suzuki, Wen-Ching Chuang

  2. Overview of the Korean Economy • GDP/ Capita & GDP

  3. Overview of the Korean Economy (Cont.) • Inflation rate & Unemployment rate

  4. Challenges for the Future • Slowing GDP Growth

  5. Challenges for the Future (2) • Fertility Rate & Population Growth Rate

  6. The impacts of the changes in population growth rates 1) The sustainable growth rate at the steady state level 2) The changes in capital accumulation and income per worker

  7. f(k) f(k*) (n+g+δ) k sf(k) Capital per effective worker (k) k* Sustainable growth rate (1) Investment, Depreciation

  8. Sustainable growth rate (2)

  9. Sustainable growth rate (3) • Note: As Y* = (y*)* (# of workers), %⊿Y*= %⊿y*+ %⊿(# of workers) - The decline in the ratio of labor force per population will have a further negative impact on the growth rate.

  10. The change in the standard of living (1) Assuming other things are all equal… Investment, Depreciation f(k) f(k2*) f(k1*) (n1+δ) k (n2+δ) k sf(k) k1* k2* Capital per worker (k)

  11. The change in the standard of living (2) MPK2 f(k) Investment, Depreciation • Lower MPK • But, still higher capital accumulation • And, higher standard of living MPK1 sf(k) k1* k2* Capital per worker (k)

  12. The change in the standard of living (3) The possible consequences of lower population growth • Larger deficit w/ burden of social expense • Growing population w/o income • Smaller population of future generation Lower Savings Rate??

  13. The change in the standard of living (4) The historical changes in national savings rate

  14. The change in the standard of living (5) The relationship between population growth rate and national savings rate from 1990

  15. The change in the standard of living (6) Scenario 1: leading to lower standard of living (n1+δ) k (n2+δ) k Investment, Depreciation s1f(k) s2f(k) k2* k1* Capital per worker (k)

  16. The change in the standard of living (7) Scenario 2: leading to higher standard of living (n2+δ) k (n1+δ) k Investment, Depreciation s1f(k) s2f(k) Capital per worker (k) k1* k2*

  17. The change in the standard of living (8) Quantitative simulation 1 (w/o technology growth)

  18. Quantitative simulation 1 (w/o technology growth) The change in the standard of living (9) f(k) f(k2005*) f(k2010*) f(k2020*) f(k2030*) (nn+δ) k snf(k) Capital per worker (k) kn*

  19. The change in the standard of living (10) Quantitative simulation 2 (w technology growth)

  20. The implications of our analysis • A low population growth rate has an adverse impact on sustainable growth at the steady state level • A lowering population growth rate, accompanied with a decreasing savings rate, has an adverse effect on the level of the standard of living

  21. What should the government do? • Increase population growth rate • Change the labor structure • Improve the pace of technological advancement • Increase savings rate

  22. Increase population growth rate • Increase fertility rate • subsidy to families with children • laws friendly to working mothers • tax reductions • day-care system

  23. Change the labor structure • Now, only 47%-50% women participating in labor force • How to encourage more women to work ? • Offer various training programs • Again, day-care center • Extend the retirement age

  24. Improve the pace of technological advancement • Provide tax reduction in R&D • Provide grants for universities or research institutes • Enforce patent laws, property right protection regulations

  25. Increase savings rate • Tax reduction may be an effective policy to increase private savings • What kinds of tax should be reduced? • capital gains tax • estate tax • and corporate income tax…
