  1. Risks within China Lecturer: Zhigang Li

  2. Motivation • Common Risks: Economic growth is not a smooth process. The uncertainty of economic growth could affect long-term growth rates. • What have been underlying the uncertainty of China’s growth? • How will they change in the future? • Idiosyncratic risks: Even if the economy is stable, risks may exist in many dimensions that may affect the investment and consumption activities of individuals or firms. • Health risk • Default risks • What could be done to reduce the risks?

  3. Outline • Common risks and growth • Theory • Evidence from the world • Evidence for China • Idiosyncratic risks within China • Evidence for China

  4. Risks Total risks = common risks + idiosyncratic risks

  5. How could risk be measured? • A typical proxy of risk is the realized volatility (or variance) of economic time series • More sophisticated measurement of risk can be inferred using GARCH models and Stochastic Volatility models.

  6. Theory: How could risks affect economic growth? • Neoclassical growth model (Solow, 1956) • Volatility plays no role for growth • Real business cycle (RBC) models (e.g. Kydland and Prescott, 1982) • The volatility of shocks to the economy may affect the level of growth (but not the growth rates of technology)

  7. Theory: How could risk affect economic growth? • Francois and Lloyd-Ellis (2003): Growth and business cycles can be positively linked via creative destruction. • Wen and wang (2006): Because of imperfect competition, firms charge higher prices during periods of larger volatility. Higher markup leads to lower capacity utilization and lower rate of return to capital. • Exchange rate risks could decrease investment and growth (e.g. Aghion et al.). • Inflation uncertainty could also affect growth. • Irriversibility of investments: When investments are irreversible, idiosyncratic investment risks could reduce firms’ investments (Jamet, 2004).

  8. Evidence: How could risks affect economic growth? • Lucas (1987) • Welfare gains of eliminating fluctuations are trivial compared to that of stimulating long-run growth • Ramey and Ramey (1995) • Countries with higher output volatility tend to have lower output growth. • Wang and Wen (2006) • Further stabilizing the U.S. economy can increase welfare by 25% of annual consumption. stabilizing output growth (or capacity utilization) around a potential target.

  9. Exchange Rate Uncertainty • Aghion, Bacchetta, Ranciere and Rogoff • For countries with relatively low levels of financial development, exchange rate volatility generally reduces growth, whereas for financially advanced countries, there is no significant effect. • A 50 percent increase in volatility uncertainty leads to a 0.33 percent reduction in exchange rate volatility.

  10. Common risks of China • Fluctuation due to policy changes • Exchange rate risks • Inflation risks • Efficiency of (physical) capital market (reducing the irreversibility of investments) • Risks of external markets

  11. Sources of idiosyncratic risks within China • Political connection • Political connection disrupts price information in the market • The market for political power is inefficient itself • Presentation by Chunyuan Shi • Contract risk (property rights) • Presentation by Yitian Li • Structural change of economic environment • Presentation by Xiaomeng Li • Health • Poor coverage of commercial health insurance and low quality of health service in rural China

  12. How could risk be reduced? • Economic development itself could actually reduce the effect of political connections • Reduced effect of political forces • Market integration (presentation by Fan Meng) • Government should be an important force • Help reduce exchange rate volatility • Public social insurance (presentation by Hao Liang) • Monitoring the financial sector (presentation by Yuanyuan Cao)

  13. How are the different risks expected to change in the future? • Institutional environment • Policy making process • Contract enforcement • Property rights • Exchange rate scheme • Inflation uncertainty • Globalization • The development of financial market • Social security net

  14. CNY/USD exchange rates

  15. Frankel (2008) • What has the de facto exchange rate regime of China been since 2005? • By mid-2007, the RMB basket had switched a substantial part of the dollar's weight onto the euro.

  16. Inflation rates of China (Funke, 2006)

  17. Conditional volatilities of inflation and output for China (Narayan et al., 2009)

  18. Thesmar and Thoenig, 2004 • Capital market development, by improving risk sharing between listed firms, increases the willingness of these firms to take risky bets. This in turn increases firm level uncertainty. • This effect could further diffuse to non-listed firms. • The spillover effect is larger when competition increases, and when labor market institutions are flexible. • Financial Market Development and the Rise in Firm Level UncertaintyPreview Thesmar, David; Thoenig, Mathias; 2004, C.E.P.R.
