FINA807 Financial Econometrics
2022 Semester 2
Project III
5 marks for the quality of the presentation. The answers for Exercise I should be provided in a folder that is zipped. The folder should contain:
1. The Eviews files that perform the computations (and contain the data). The project has to be done in Eviews.
2. A small word document with:
■ Your name, surname, ID number and other standard information.
■ Graph, if any, produced by the code as well as commented results.
The archive name must be: YourIDnumberProject3.zip
The folder name must be: YourIDnumberProject3
The symbol ■ indicates the end of a question.
Exercise I
(Total: 10 marks). GARCH/EGARCH/TGARCH/GARCH-M .
You select two stocks and download four years of daily data from Workspace.
1. (2 marks) Plot the stock evolutions and provide for each company a very short description of its activity (3 lines max). ■
2. (2 marks) Using these two stocks, for each one estimate a GARCH(1,1) process (only one lag in the volatility) using four years of daily data and comment the results. ■
3. (2 marks) Using these two stocks, for each one estimate a EGARCH(1,1) process (only one lag in the volatility) using four years of daily data and comment the results. In particular you should pay attention to whether it displays the asymmetric effect. ■
4. (2 marks) Using these two stocks, for each one estimate a GJR/TGARCH(1,1) process (only one lag in the volatility) using four years of daily data and comment the results. In particular you should pay attention to whether it displays the asymmetric effect. ■
5. (2 marks) Using these two stocks, for each one estimate a GARCH(1,1)-M process (only one lag in the volatility) using four years of daily data and comment the results. ■
Exercise II
Download 5 years of credit default swap (CDS) with maturity 5 years (RIC:CDXIG5Y=R) denoted cds5Yt , 7 years (RIC:CDXIG7Y=R)
denoted cds7Yt and (RIC:CDXIG10Y=R) denoted cds10Yt . For a short description of what is a CDS, type in Workspace
“credit default swap” and Wikipedia the pages “credit default swap” and “credit default swap index”. The CDXIG5Y is a credit default swap index with maturity 5 Y for investment grade companies.
1. (2 marks) Consider the two CDSs yt = cds5Yt and x = cds7Yt . Plot t → yt and t → xt . ■
2. (2 marks) Estimate the linear model
yt = c0 + c1 xt + ut , (1)
and store the residuals ut in a variable denoted statsresidt . ■
3. (2 marks) Perform an ADF test on statsresidt and check that you can reject the null (i.e. the null hypothesis of a unit root in the residuals) as the t-stat is below the critical value. ■
4. (2 marks) Estimate the model
∆yt = b0 + b1 ∆xt + b2 (statsresidt − 1 ) + ct , (2)
that is the same as
= 0 + b1 ∆xt + b2 (yt − 1 _ c1 xt − 1 ) + ct , (4)
so b2 and c1 constitute the error correction term coefficients. ■
5. (2 marks) Once b2 and c1 are estimated, see if you can interpret Eq. (4) in terms of credit default swap evolutions. ■
6. (2 marks) Redo the analysis for yt = cds7Yt and x = cds5Yt and check that you reach the same conclusions. If you find that b2 for the pair (yt = cds5Yt , x = cds7Yt ) is different than b2 for the pair (yt = cds7Yt , x = cds5Yt ), what does it mean? ■
7. (4 marks) Perform questions 1. to 5. for the pair (yt = cds5Yt , xt = cds10Yt ). Comment the results. ■
8. (4 marks) Perform questions 1. to 5. for the pair (yt = cds7Yt , xt = cds10Yt ). Comment the results. ■
