  19. HOW MONETARY POLICY COMBATS INFLATION Fig 13.6 p 321 Tighten monetary policy

  20. If actual output > potential output, restrictive monetary policy will reduce dangers of inflation Objective is to secure a soft landing ….

  21. If actual output < potential output, expansionary monetary policy will reduce danger of deflation Objective is to secure price stability… Need for reflation, or “mild” inflation to solve private debt trap?

  22. Limitations of monetary policy in dealing with Deflation • Nominal interest rate cannot go below zero (ZIRP) • When prices are falling, real interest rate can stay high even as nominal rate falls • Hence monetary policy may not have sufficient stimulative impact to combat recession • FUNDAMENTAL LIMITATION: expansionary monetary policy encourages spending --- but it cannot force people to borrow and spend (Also potential danger of overstimulus causing inflation)

  23. Reform of the Financial Sector also needed • “Too big to fail” banks must be taxed to compensate • taxpayer for implicit government guarantee: • “specific capital surcharges for systemically important • financial institutions can be a useful • tool and should be accompanied by resolution plans • vetted by regulators” (OECD). • Structural separation between retail and investment • banking also needed • 3. Reduce incentive to get too big to fail by taxing the • equivalent of the implicit guarantee. • 4. Improve supervision and incentives system

  24. Quantitative Easing • What is it? • b) Can it help to restore credit growth?

  25. Limitations of monetary policy in dealing with Inflation • High nominal interest rate may be needed to curb over optimism and restore balance • Danger or over reaction to short term price changes • Insufficient attention to asset price movements

  26. Questions for Group work • Define price stability. Why is attainment of price stability important? • 2. What intermediate targets can a central bank set to ensure that price stability is maintained? • 3. What policy actions can a central bank take to preserve price stability? • 4. Would a cut in interest rates be an effective way of stimulation aggregate demand in the Euro Area? • Does business prefer rising prices (inflation) to falling prices (deflation)? • Or are both equally undesirable? Explain.

  27. Questions for Group work (2) Exercise 3 p. 304

  28. CONCLUSIONS • Price stability is good for economic growth • Deflation is just as damaging as inflation • Aggressive monetary policy necessary to avoid booms and busts • But not always sufficient ... • In times of crisis, fiscal policy also needed
