The Price Stability Goal and the Nominal Anchor
SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 1
• Over the past few decades, policy makers throughout the world have become increasingly aware of the social and economic costs of inflation and more concerned with maintaining a stable price level as a goal of economic policy.
• The role of a nominal anchor: a nominal variable such as the inflation rate or the money supply, which ties down the price level to achieve price stability. It can limit time inconsistency problem.
Other Goals of Monetary Policy
SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 2
• Five other goals are continually mentioned by central bank officials when they discuss the objectives of monetary policy:
(1) high employment and output stability
(2) economic growth
(3) stability of financial markets
(4) interest-rate stability
(5) stability in foreign exchange markets
Should Price Stability Be the Primary Goal of Monetary Policy?
SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 3
Hierarchical Versus Dual Mandates:
• hierarchical mandates put the goal of price stability first, and then say that as long as it is achieved other goals can be pursued
• dual mandates are aimed to achieve two coequal objectives: price stability and maximum employment (output stability)
• Price Stability as the Primary, Long-Run Goal of Monetary Policy
- Either type of mandate is acceptable as long as it
operates to make price stability the primary goal in the long run, but not the short run. Why?
Objective of the European Central Bank
SuSe 2013 4
• To maintain price stability is the primary objective of the Eurosystem and of the single monetary policy for which it is responsible. This is laid down in the Treaty on the Functioning of the European Union, Article 127 (1).
• "Without prejudice to the objective of price stability", the Eurosystem shall also "support the general economic policies in the Union with a view to contributing to the achievement of the objectives of the Union". These include inter alia "full employment" and "balanced economic growth".

Inflation Targeting
SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 5
• Public announcement of medium-term numerical target for inflation
• Institutional commitment to price stability as the primary, long-run goal of monetary policy and a commitment to achieve the inflation goal
• Information-inclusive approach in which many variables are used in making decisions
• Increased transparency of the strategy
• Increased accountability of the central bank
Inflation Targeting
SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 6
• New Zealand (effective in 1990) Inflation was brought down and remained within the target most
of the time.
Growth has generally been high and unemployment has come down significantly
• Canada (1991)
Inflation decreased since then, some costs in term of unemployment
• United Kingdom (1992)
Inflation has been close to its target.
Growth has been strong and unemployment has been decreasing.

Inflation Targeting
SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 8
• Advantages
Does not rely on one variable to achieve target
Easily understood
Reduces potential of falling in time-inconsistency trap
Stresses transparency and accountability
• Disadvantages
Delayed signaling
Too much rigidity
Potential for increased output fluctuations
Low economic growth during disinflation
The ECB’s Monetary Policy Strategy
SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 9
• ‘Price stability shall be defined as a year-on-year increase in the Harmonised Index of Consumer Prices (HICP) for the euro area of below 2%’ (ECB Monthly Bulletin, January 1999, p. 46).
• In 2003, the ECB stated that it pursued an inflation objective below, but close to, 2%.
• Price stability ‘is to be maintained over the medium run’
• The ECB pursues a hybrid monetary policy strategy that includes elements of both monetary targeting and inflation targeting.
The ECB’s Monetary Policy Strategy
SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 10
• A ‘two-pillar’ approach is proposed as a strategy.
• The first pillar is a monetary one.
• A forecast of future trend growth of real GDP ~ 2%, Δv = - 0.5%. (See Monthly Bulletin of January 1999 )
• The money stock (M3) should not be increasing by more than 4.5% per year. This number is not a target but rather a reference value!

SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 11
• The second pillar includes a number of variables, such as wages, the exchange rate, bond prices and the yield curve, various measures of real activity, fiscal policy indicators, price and cost indices and business and consumer surveys, to forecast future inflation. (ECB Monthly Bulletin, January 1999, p. 49).

• The selection of the target: Only one target of monetary policy?
• ECB has been quite successful in achieving the objective of price stability

• In case there is a trade-off between inflation and output stabilization, the ECB has made it clear that it will pursue price stabilization.
• Some focus on output stabilization through gradualism: lower the inflationary pressures gradually
• What about financial stability?

Lessons for Monetary Policy Strategy from the Global Financial Crisis
SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 16
1. Developments in the financial sector have a far greater impact on economic activity than was earlier realized
2. The zero-lower-bound on interest rates can be a problem
3. The cost of cleaning up after a financial crisis is very high
4. Price and output stability do not ensure financial stability

• How should Central banks respond to asset price bubbles?
Asset-price bubble: pronounced increase in asset prices that depart from fundamental values, which eventually burst.
• Types of asset-price bubbles
Credit-driven bubbles
• Subprime financial crisis
Bubbles driven solely by irrational exuberance
Lessons for Monetary Policy Strategy from the Global Financial Crisis
SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 18
• Should central banks respond to bubbles?
Strong argument for not responding to bubbles driven by irrational exuberance
Bubbles are easier to identify when asset prices and credit are increasing rapidly at the same time.
Monetary policy should not be used to prick bubbles.

• Macropudential policy: regulatory policy to affect what is happening in credit markets in the aggregate.
• Monetary policy: Central banks and other regulators should not have a laissez-faire attitude and let credit-driven bubbles proceed without any reaction.
Tactics: Choosing the Policy Instrument
SuSe 2013 Monetary Policy and EMU: The Conduct of Monetary Policy 20
• Tools
Open market operation
Reserve requirements
Standing facilities
• Policy instrument (operating instrument)
Reserve aggregates
Interest rates
May be linked to an intermediate target
• Interest-rate and aggregate targets are incompatible (must chose one or the other).
