Refer to the Regression worksheet.
This worksheet contains (i) monthly returns of a portfolio of five risky assets, (ii) monthly
returns of the market index, (iii) monthly returns of the risk-free asset, (iv) monthly
excess returns of the above portfolio of five risky assets, (v) the month-to-month change
in COVID-19 cases, expressed in percentage points, and (vi) the month-to-month change
in the size of the central banks balance sheet (lagged by one period).
Estimate the following regression models and paste the outputs precisely at the specified
ranges in the worksheet. Outputs, even if they are correct, that are pasted at the wrong
locations will receive zero credit.
(a) [5 marks] Set output range to cell M4. Interpret the intercept, and the estimated
coefficient on % Change in COVID cases
Excess returnsportfolio = + 1 % Change in COVID cases +
(b) [5 marks] Set output range to cell M27. Interpret the intercept, and both estimated
coefficients.
Excess returnsportfolio = + 1 % Change in COVID cases
+ 2 % Change in CB balance sheet +
Compute the root mean squared errors (RMSE) of your regression models. Show all
computations in the worksheet clearly. Answers, even if they are correct, that are unac-
companied by worksheet computations will receive zero credit.
(c) [5 marks] What is the RMSE of the model in part (a)?
(d) [5 marks] What is the RMSE of the model in part (b)?
