Q

What do economists say happens in the short term when a currency depreciates?

A
  • they say that in the SR, the Marshall-Lerner condition is not met as demand tends to be inelastic for both exports and imports
  • this may be due to the time taken to adjust to changes currency value
  • consumers may not comprehend the currency value change and therefore not change their behaviour accordingly
  • it may also take foreign nations time to realise goods from e.g. the UK have become cheaper

Q

The J Curve effect

A
  • Economists argue that in the SR, when there is currency depreciation, the Marshall Lerner condition does not hold, as demand tends to be inelastic for both imports and exports so much so that the total elasticity is less than 1 of net exports
  • consumers, foreign countries and firms take time to adjust to the fact that exports have changed in price and so continue to buy at the same rate as before
