Let $A_t$ be the amount of money at the beginning of year $t$ and let $r$ be the interest rate. Assume that each year, we invest an additional amount of $Q$ Then we can recursively write this as: $$ A_t = (1+r)A_{t-1} + Q. $$ So the amount at time $t$, $A_t$ is the amount last year $A_t$ plus a percentage $r$ of $A_t$ plus $Q$. We would like to find a closed ...

Because of exchange rate and uncovered interest rate parity (UIP). By the UIP the following relationship should hold between nominal interest rates and exchange rates: $$ (1+i_{t}^$) = \frac{E_t(S_{t+1})}{S_t}(1+i_{t}^€)$$ In short, the ratio of expected future nominal exchange rate ($E_t(S_{t+1})$) and current nominal exchange rate ($S_t$) should make the ...

Consequently, the direct answer to your question ...
