Assignment
1. Table 1.2 gives data on the Consumer Price Index (CPI) for seven industrialized countries with 1982-1984 =100 as the base of the index.
a. From the given data, compute the inflation rate for each country.
b. Plot the inflation rate for each country against time (i.e. use the horizontal axis for time and the vertical for the inflation rate.)
c. What broad conclusions can your draw about the inflation experience in the seven countries?
d. Calculate descriptive statistics and explain which country's inflation rate seems to be most variable?
Hint: inflation rate = ((Pt-Pt-1)/Pt-1); For variability compare the values of variance (standard deviation) or coefficient of variation.
