question 15

Multiple Choice

The following regression model was estimated by Delta Corporation to forecast the value of the Indian rupee (INR) :
$$I N R_{t}=a_{0}+a_{1} I N T_{t}+a_{2} I N F_{t-1}+\mu_{t}$$
where INR is the quarterly change in the rupee, $I N T$ is the real interest rate differential in period $t$ between the U.S. and India, and $I N F$ is the inflation rate differential between the U.S. and India in the previous period. Regression results indicate coefficients of $a_{0}=.003 ; a_{1}=-.5$ ; and $a_{2}=.8$ . Assume that $I N F_{t-1}=2 \%$ . However, the interest rate differential is not known at the beginning of period $t$ and must be estimated. Delta Corp. has developed the following probability distribution:

The expected change in the Indian rupee in period $t$ is:

• A) 3.40%.
• B) 0.40%.
• C) 3.10%.
• D) 1.70%.
• E) none of the above
