Forecasting the foreign currency prices using the Box Jenkins approach

In this thesis, the Box Jenkins approach is applied to forecast the future prices of foreign currencies, American Dollar and German Mark, in Turkey’s Black Market using available observations made between the years 1985-1988. The forecasts obtained from this approach are compared to the real available observations. The results show that the Box Jenkins approach is not accurate enough in this case because of the large mean absolute deviation between the forecasted and the observed values of these currencies due to the significant residuals generated in the diagnostic checking stage.
