  1. EC3040 Economics of LDCsModule B Topic 3 Financial sector issues

  2. Finance and development • Financial systems growth and poverty reduction • Financial crises • Microfinance • Macroeconomic stability and international finance • The debt problem

  3. 1. Financial system development and growth: Outline • How it was discovered that finance causes growth • Some evidence on finance and poverty • Measuring finance: • Weakness of banking depth • An alternative based on second generation evidence

  4. Elements of the financial system • Banks (and bank-like institutions such as building societies, credit unions, microfinance institutions). Intermediaries • Markets (stock market, bond market, foreign exchange market) • Financial instruments (bank deposits, bank loans, bonds, equities…) • Other financial firms providing ancillary services (payments technologies, credit rating agencies…)

  5. Intermediaries • Pool resources from depositors and lend the proceeds to borrowers (including government and its agencies) • Provide risk-sharing services for depositors, creditworthiness appraisal and monitoring for borrowers • Also provide other services including payments (cheques, domestic and international transfers…) • Intermediaries, especially banks, form a much larger share of the financial system in developing countries than in advanced economies.

  10. But: Post hoc ergo propter hoc? The discovery that finance affects growth (and not just the other way around) Updated from Levine, 2005

  11. How can we get around chicken-and-egg problem of causality • Is the correlation between financial depth and economic growth causal? • If so, which is the direction of causation? • Richer countries produce deeper financial systems • But do deeper financial systems also generate growth? • Method of instrumental variables (remember dead bishops) • Suppose we have data on something that helps explain financial depth, but has no causal impact on growth (for example, the nature of the legal system -- stronger protection for creditors vis-à-vis debtors helps financial system) • Replace actual financial depth by its predicted value

  12. Valid instruments(A simplified note on econometric methodology) • Correlated with explanatory variables • Not independently relevant to explaining dependent variable • Predicted value from regression of explanatory variables on instruments used to explain dependent variable (growth) • Example: legal origin
