Monetary Integration Flashcards
Nominal exchange rates
Refers to the price of one country’s currency in terms of another
Real exchange rates
Real ER = nominal ER x relative prices
In the Eurozone which type of ER is fixed and which can vary?
The nominal ER is fixed but the real ER can vary
In the long run what should happen to ER?
ER should reflect “law of one price” as the market should eliminate price differences through trade. Nominal ER should exactly balance the price ratio, leaving the real ER everywhere at 1
How can a country with a high real ER restore competitiveness?
- reduce prices through deflation by cutting demand, lowering costs, often leading to unemployment.
- devaluation of nominal ER, effective in SR but arguable impact in longer term. Counties that share a currency can’t do this
Why do some countries peg their ER to other countries?
In the forex market, the exchange rate tends to overshoot which has a destabilising effect. This is undesirable, so pegging to another country helps limit this
Example of country with pegged ER?
Hong Kong to US
Bretton woods system
A system post ww2 where each currency was maintained +/- 1% of the dollar
Why is stabilising ER hard in the medium run?
Because of the impossible trio
What is the impossible trio
- Stable nominal ER
- Free trade and investment flows
- Independent monetary policy
All of these are desirable but not all 3 can be achieved in the medium term
Describe the collapse of the exchange rate mechanism (ERM)
- in 1979, a number of EU counties committed to maintaining their nominal ER in a narrow band with Germany being the nominal anchor
- in 1992/3 german re-unification boom caused inflation and subsequently interest rates rose
- other countries had to either raise interest rates to match Germany or allow their nominal ER to fall
- they tried raising interest rates but this worsened the recession at home
- government eventually made curing the recession a priority over maintaining the ER leading to collapse of ERM
Benefits of a common currency
- Elimination of transaction costs
- Greater price transparency, note product price differences in eurozone still remain quite high
- Removal of exchange rate uncertainty, encourages production and investment decisions, lower interest rates offered by banks
- Economic growth, lower interest rates increase investment
- Gains from seigniorage (difference between value of money and costs of producing it) increased development of financial market
Costs of a common currency
- Loss of exchange rate as an adjustment mechanism. To restore competitiveness, countries must do so through deflation which causes unemployment and reduced GDP
Mundell optimum currency area theory
Countries sharing a currency must have labour market flexibility. This will help offset asymmetric shocks without the need for wage adjustments
What does EMU stand for?
Economic and Monetary Union
What does the EMU involve?
- Single currency (euro)
- Institution to determine and administer monetary policy (ECB)
- Unified monetary policy, single interest rate, joint control of money supply and exchange rate
- Free movement of capital
- Coordinated tax policies
