Alpha and Beta are two countries. Alpha uses dollars ($) and Beta uses pounds (£). Treat Alpha as the home country and define the bilateral exchange rate as the number of pounds that exchange for one dollar: co || GA | M The following table provides some annual exchange rate data. 2016 2017 2018 2019 e 0.6 0.56 0.50 0.45 (i) Discuss how the theory of Purchasing Power Parity would explain the behaviour of the exchange rate over the period 2016 to 2019? (2 marks) (ii) Suppose we use the supply and demand model to interpret the above data. Examine the ability of differences in the growth rates of real GDP between Alpha and Beta to explain the behaviour of the exchange rate over the period 2016 to 2019?
