  1. Monetary Accounts: An Overview • Why stress money? • Money affects output, inflation, and the balance of payments • Money is a medium of exchange that greases the wheels of production and trade Thorvaldur Gylfason

  2. Outline • Role of money • Money and banking • Money and the balance of payments • Forecasting money • Money, prices, and income

  3. Quantity Theory of Money • Oldest macroeconomic theory • MV = PY • V = PY/M (velocity) • P = (V/Y)M P The price level is approximately proportional to the money supply over long periods Long-run relationship M

  4. Quantity Theory of Money • To keep the price level under control, it is essential to control the money supply P This is why money and monetary policy must play a key role in financial programming Long-run relationship M

  5. The Role of Money • Generally, we need to control money to manage aggregate demand • Money affects aggregate demand directly and indirectly P Direct effect through interest rates and investment Indirect effect • through interaction with fiscal policy Aggregate supply Aggregate demand Y

  6. Direct Effects of Money • An increase in money supply increases supply of loanable funds, • thus driving down interest rates • As interest rates fall, investment rises, • thus increasing aggregate demand r Supply of loanable funds Hence, monetary expansion increases the price level and also output, as long as the aggregate supply schedule slopes up Demand for loanable funds S, I

  7. Indirect Effects of Money • An increase in government budget deficit needs to be financed • If it is financed by credit from the banking system, i.e., by increasing the money supply, then ... P ... aggregate demand will rise (a) because of the expansionary effect of the increased government budget deficit and (b) because of the effect of the monetary expansion used to finance it Aggregate supply Aggregate demand Y

  8. Money is Useful The ratio of money supply to nominal income reflects the degree of monetization Mature economies generally have higher ratios of money to income than developing economies * 1997

  9. But What is Money? • Liabilities of banking system to the public • that is, the private sector and public enterprises • M = C + T • C = currency, T = deposits • The broader the definition of deposits ... • demand deposits, time and savings deposits, etc., • ... the broader the corresponding definition of money • M1, M2, etc.

  10. Overview of Banking System

  11. Balance Sheet of Central Bank DG = domestic credit to government DB = domestic credit to commercial banks RC = foreign reserves in Central Bank C = currency B = commercial bank deposits in Central Bank

  12. Balance Sheet of Commercial Banks DP = domestic credit to private sector RB = foreign reserves in commercial banks B = commercial bank deposits in Central Bank DB = domestic credit from Central Bank to commercial banks T = time deposits

  13. Balance Sheet of Banking System Monetary Survey D = DG + DB = net domestic credit from banking system (net domestic assets) R = RC + RB = foreign reserves (net foreign assets) M = money supply

  14. A Fresh View of Money • The monetary survey implies the following new definition of money: • M = D + R • where M is broad money (M2), which equals narrow money (M1) + quasi-money • This is one of the most useful equations in all of economics • Money is, by definition, equal to the sum of domestic credit from the banking system (net domestic assets) and foreign exchange reserves in the banking system (net foreign assets)

  15. An Alternative Derivation of Monetary Survey • Public sector • G – T = B + DG + DF • Private sector • I – S = DP - M - B • External sector • X – Z = R - DF • Now, add them up

  16. An Alternative Derivation of Monetary Survey • Public sector • G – T = B + DG + DF • Private sector • I – S = DP - M - B • External sector • X – Z = R - DF

  17. An Alternative Derivation of Monetary Survey • Public sector • G – T = B + DG + DF • Private sector • I – S = DP - M - B • External sector • X – Z = R - DF

  18. An Alternative Derivation of Monetary Survey • Public sector • G – T = B + DG + DF • Private sector • I – S = DP - M - B • External sector • X – Z = R - DF Hence, M = D + R • So, adding them up, we get 0 = D - M + R because DG + DP = D

  19. A Fresh View of Money • The monetary survey (M = D + R) has three key implications: • Money is endogenous • If R increases, then M increases • Important in open economies • Domestic credit affects money • If R increases, may want to reduce D to contain M • R = M - D • where R = X – Z + F • Monetary approach to balance of payments

  20. Monetary Approach to Balance of Payments • The monetary approach to the balance of payments (R = M - D) has the following important implication, in three parts • Need to • Forecast M and then • DetermineDin order to • Meet target for R • Hence, D is determined as a residual given both M and R* • R* = reserve target, e.g., 3 months of imports

  21. Monetary Approach to Balance of Payments • Domestic credit is a policy variable that involves both monetary and fiscal policy • Can reduce domestic credit(D) • To private sector • To public sector • By reducing government spending • By increasing taxes and fees • Monetary and fiscal policy are closely related through domestic credit

  22. Forecasting Money • Money is determined by equilibrium between money demand and money supply • Money demand, like the demand for goods and services, depends on • Income, i.e., GNP • Price, i.e., the opportunity cost of holding money • Inflation rate in developing countries • Interest rate in industrial countries

  23. Forecasting Money Demand • Theory and empirical evidence • When GNP goes up, so does the demand for money • Transactions demand • When inflation goes up, money demand goes down ... • ... because the opportunity cost of holding money goes up with inflation • Speculative demand • So, to forecast money, need first to forecast income, price level, and inflation

  24. Forecasting Money Demand: An Example • M/P = Ya e- b • log(M/P) = a log(Y) – b • a = income elasticity • Income effect means that a  0 • Typically, a is around 1 • b = inflation semi-elasticity • Inflation effect means that b > 0 • For example, b can be around 5

  25. Equilibrium of Supply and Demand For Money M Money demand Money supply Nominal income depends on the money supply PY

  26. Effects of an Increase in Money Supply M Money demand B Money supply A An increase in money supply increases nominal income PY

  27. Effects of an Increase in Inflation Rate M Money demand A Money supply B An increase in inflation reduces money holdings relative to income PY

  28. Financial Depth and Economic Growth Indonesia Japan Switzerland Jordan r = 0.66 85 countries

  29. Financial Depth and Inflation Hong Kong r = -0.51 Switzerland Nicaragua Jordan Angola Congo, Dem. Rep. 160 countries

  30. Financial Depth and Inflation, Again r = -0.51 Indonesia Japan Switzerland Jordan 160 countries

  31. Effects of Increases in Money Supply and Inflation M Monetary expansion, by increasing inflation, reduces money holdings relative to income, thereby impeding efficiency and economic growth, even if nominal income rises in the short run Money demand B A Money supply PY

  32. Effects of Increases in Money Supply and Inflation M Monetization is a good thing, but printing money is not the way to achieve it On the contrary, monetary expansion reduces the amount of money available to finance economic transactions Money demand B A Money supply PY

  33. Conclusion • Need to forecast monetary expansion to be able to determine the rate of credit expansion that is consistent with our reserve target • Base forecast of monetary expansion on forecast of income growth and inflation M = D + R

  34. Bottom line These slides – and more! – can be viewed on my website: www.hi.is/~gylfason • Need to control credit expansion – and hence apply fiscal restraint – to achieve the rate of monetary expansion that is consistent with our international reserve target • Key to financial programming M = D + R
