1. What is the “optimal” level of financial development? 2. What is the “relevant benchmark” for financial development? 3. What factors explain cross-country differences? 4. What are the policy implications?

5. 1 . What is the “optimal” level of financial development?
“Despite these developments, many emerging countries still lag behind the progress witnessed by advanced nations and convergence is still largely failing to happen.” (Abstract)
Limited theoretical and empirical knowledge on:
- the optimal level of financial development
- the necessity of the convergence of financial systems

6. Is “too much finance” always good?
LONG-RUN: Positive relationship between (intermediate levels of) financial development and growth (Levine, 2004)
SHORT-RUN: Financial sector can be a source of macro volatility (Kindleberger, 1978; Reinhart and Rogoff, 2009)
“Has financial development made the world riskier?” Yes. (Rajan, 2005)
Can “too much finance” have a negative impact on growth? Yes… Threshold: Credit/GDP=110 percent (Arkand, Berkes and Panizza, 2011)

7. Credit Boom and Financial Development: Twins?
Rapid credit growth (a credit boom) is often associated with an increase in the level of financial development
Credit growth during the boom can have
- spillover effects on financial development over the long-run
- an amplifying impact over the short-run (deeper recessions…)

8. Credit Booms and Financial Development

9. Credit Booms: Not Always Happy Endings

10. Unconditional Probability of Recession: Lower… ( fraction of time in recession)

11. But Recession More Likely w/ a Credit Crunch (fraction of time in recession given a disruption)

12. Recessions More Costly w/ Credit Crunches (cumulative losses, in percent)

13. 2. What is the “relevant benchmark” for financial development?
Emerging markets are compared with advanced countries
Can we think of some statistical benchmarks for different indicators of financial development?
FinStats 2011: A Ready-to-Use Tool to Benchmark Financial Sectors across Countries and Over Time
(Al-Hussainy, et.al., 2011, World Bank)

14. Constructing Benchmarks Require Lots of Data
40 indicators of fin development; 120 countries;
How to determine the benchmarks? Run quintile regressions of financial development indicators on a set of explanatory variables (gives regional and income level benchmarks)
Factors of economic development (GDP per capita); population factors (population size, density); demographic factors (age dependency ratios); country factors (oil exporters, financial centers); global cycle

15. Korea: Financial Sector Development - 1 (Real Credit / GDP , in percent)

16. Korea: Financial Sector Development - 2 (Stock Market Capitalization / GDP, in percent)

17. 3. What factors explain cross-country differences?
Extensive evidence of substantial differences in financial development across countries and over time
Useful to consider the possible factors explaining these differences: policy driven; institutional dimensions; structural elements; supply and/or demand driven; and global factors (capital inflows)
Regressions involving the temporal changes in the indicators of financial development on some potential determinants

18. 4. What are the policy implications?
“… emerging economies will need to catch up, grow their financial systems, and take more risk, in their process to become more similar to developed nations.” (Conclusion)
A well-functioning financial sector: encourages idiosyncratic risk without elevating systemic risk
Emerging markets need to have deep, but effectively regulated, financial systems

19. Potential Factors: Not Macro Anymore?
Stronger growth prospects with sound macro policies
Institutional environment
Regulation and supervision, legal system, and governance
State role in financial sector (ownership)
Also helpful thinking about policy implications….

20. Policy Challenges Abound
Emerging markets need to deepen their financial markets
But, at the same time, make progress in advancing the quality of institutional structures, regulation and supervision of financial sector, and aligning macro and prudential policies
How much have they been able to do that over the past two decades? Would be good to document changes in policies/institutions as well
