Again, consider the East and West economy, in its first version of Question 4 with equal money supplies in the two countries. Suppose that at date 0 a technological breakthrough is announced that will allow West permanently to produce 50,000 more units of Food and 50,000 more units of Clothing with the same number of workers as before, thus keeping world relative supply unchanged. However, the increased output will begin only at date t = 1. How does this announcement change the equilibrium? Discuss consumption, production, nominal prices and exchange rates, both at date t = 0 and at date t = 1.
