What does the equation $E_{t} riangle s_{t,t+1} = i_{t,t+1} - i_{t,t+1}^*$ express?
Understand the Problem
The question is asking for an explanation of the meaning of a specific economic equation involving variables related to exchange rates and interest rates. It requires familiarity with concepts from finance and macroeconomics to discern what the equation expresses.
Answer
It expresses a relationship often seen in finance, relating to interest rate parity and exchange rate expectations.
The equation $E_t \triangle s_{t,t+1} = i_{t,t+1} - i_{t,t+1}^$ generally expresses a relationship in finance or economics, often associated with the uncovered interest rate parity condition where $E_t$ represents the expected rate of change in the exchange rate, $i_{t,t+1}$ is the domestic interest rate, and $i_{t,t+1}^$ is the foreign interest rate.
Answer for screen readers
The equation $E_t \triangle s_{t,t+1} = i_{t,t+1} - i_{t,t+1}^$ generally expresses a relationship in finance or economics, often associated with the uncovered interest rate parity condition where $E_t$ represents the expected rate of change in the exchange rate, $i_{t,t+1}$ is the domestic interest rate, and $i_{t,t+1}^$ is the foreign interest rate.
More Information
This equation is often used to describe the expectations about changes in exchange rates based on domestic and foreign interest rates. The concept is rooted in the theory of interest rate parity in international finance.
Tips
A common mistake is misunderstanding the role of $E_t$, which is the expectation rather than an actual value.
