3. (Valuation Changes) Suppose that over the period 2017 to 2019, the net international investment position of a country was NIIP2017= 100,NIIP2018=125, and NIIP2019=130. Suppose that over the same period, the current account was CA2017=30,CA2018=20, and CA2019=10. Calculate valuation changes in 2018 and 2019. 3.
