UNDERSTANDING

EXCHANGE RATES (1)


What is an exchange rate l.jpg
What is an “exchange rate”?

  • The price of one currency in terms of another (say dollars per euro) is called the exchange rate.

  • Foreign exchange (forex) transactions are effected on specific markets for:

    • spot transactions;

    • forward transactions;

    • futures transactions;

    • options

Appreciation and depreciation

  • If you pay more € for forex, your currency € is said to “depreciate”; if you pay less, your currency “appreciates”


Why are exchange rates important l.jpg
Why are exchange rates important?

  • They affect the relative price of domestic and foreign goods.

  • When a country’s currency appreciates, the country’s goods become more expensive abroad, and foreign goods become cheaper.

  • Will the exchange rate equate foreign and domestic prices?


The law of one price l.jpg
The law of one price

  • Under market conditions, arbitrage will indeed equate prices in the different regions of the domestic economy.

  • If there are no barriers to trade, this also applies to international trade.

  • If the price level in country A is higher than in country B, the exchange rate should correct for this difference.


The law of one price6 l.jpg
The law of one price

  • Identical goods should sell for the same price in two separate markets when there are no transportation costs and no differential taxes applied in the two markets.

  • Consider the following information about movie video tapes sold in the US and Mexican markets:

    • Price of videos in US market (Pv) = $20

    • Price of videos in Mexican market (Pv) = p150

    • Spot exchange rate (p/$) = 10 p/$


The law of one price7 l.jpg
The law of one price

  • The dollar price of videos sold in Mexico can be calculated by dividing the video price in pesos by the spot exchange rate.

  • If the law of one price held, then the dollar price would have to be p150/10p/$ = $15 in Mexico to match the price in the US.

  • Since the dollar price of the video is less than the dollar price in the US, the law of one price does not hold in this circumstance.

  • If the law holds, we speak of “purchasing-power parity” (PPP).

  • The PPP theory makes sense only in the long run.

  • In the short run there are significant deviations from PPP due to short-term movements of capital.


Factors that affect exchange rates long run l.jpg
Factors that affect exchange rates: long run

  • Factors that affect the exchange rates are (w = depreciation, w = appreciation):

    • Relative price levels: if P/P*, then w

    • Tariffs and quota: if import duty , then w

    • A shift in preferences for domestic versus foreign goods:

      • if export demand , then w

      • if import demand , then w

    • Productivity: If productivity , then w
