2) Exchange rates: an introduction -MMT Flashcards
what are the 4 functions of money?
- acts as a medium of exchange
- a store of value
- a measure of value
- a standard deferred payment
what is the most important function of money? why?
medium of exchange - money is used as an accepted means of payment when we buy goods and services, quite often goods and services are exchanged between economic agents in different countries
what does “currency” mean?
the system of money used in a country
what is the currency in the UK and US?
the £ sterling, the US is the US$
how are currencies measured?
for historic reasons, most of these currencies use their own denomination, have their own system of measuring money
what is an exchange rate? (x rates)
is the price of one currency in terms of another currency
what is a fixed exchange rate?
happens when 2 currencies will always be exchanged at the same price
how are floating exchange rates determined?
determined by the private market through supply and demand
what is the private market called when dealing with floating exchange rates?
the FOREX (Foreign Exchange Market)
how does the FOREX determine the value of the floating currency?
by how much of that currency is being demanded and supplied on the FOREX
why is the x-rate diagram different to usual?
one of the few times in Macroeconomics that we use Microenconomics labels and terminology
how do you draw an x-rate diagram?
- The x-rate is the price (how many US$ we get for £1)
- D is the demand for £s
- S is the supply of £
- The quantity of £s being traded
how can floating x rates be shown on a diagram?
- P1 is the equilibrium X-rate (P of US$ to £1)
- An increase in the D for the £ will shift D curve for £s to the right, making the £ stronger against the US$
- a decrease in D for £s will shift D to the left, making the £ weaker against the US$
floating x rates, what does an increase in D mean?
- An increase in the D for the £ will shift D curve for £s to the right, making the £ stronger against the US$
floating x rates, what does an decrease in D mean?
- a decrease in D for £s will shift D to the left, making the £ weaker against the US$
How do you show fixed rate on a diagram when the £ is priced too high? (above equilibrium)
- to ensure the fixed rate that they want, the Bank of england will need to demand more £s
- they go on the FOREX buying £s and paying for them using some of the US$ that they keep in their reserves
- this brings the demand for £ back in line with the S of £s, restoring equilibrium
how do the Bank of England demand more £s?
go on the FOREX buying £s and paying for them using some of the US$ that they keep in their reserves
How do you show fixed rate on a diagram when the £ is priced too low? (below equilibrium)
- to ensure the fixed X-rate that they want, the Bank of england will need to supply more £s onto the market
- to do this they will go on the FOREX selling £s, using those £s to buy more US$ building up their reserves
- this brings the supply of £s back in line with the D for £s, restoring equilibrium
how do the Bank of England supply more £s onto the market?
- to do this they will go on the FOREX selling £s, using those £s to buy more US$ building up their reserves
