6. Choose a country (Switzerland or Japan) that experienced negative interest rates. What were the main drivers that pushed the interest rate down?

7. Perform a separate regression analysis between the interest rate of a chosen country (independent variable) and the following variables: inflation (consumer price index), change in nominal GDP, change in real GDP. Inflation and other variables should be taken from official sources (stat agencies/departments of a chosen country).

8. Briefly interpret the results of each analysis (R squared, coefficients, t-score). Explain the relationship of the interest rate to each variable
