Econometrics assignment -ASB3317
1. The due date for the assignment is the 15th December 2023
2. The word limit for this assignment is 2000 which does not include referencing, tables, figures and equations. Where an assignment exceeds the stated word limit, the following rules will apply:
a. Award a mark that reflects deficiencies in the work as submitted, that is inline with explicit marking criteria andis proportionate to the extent to which the word limit is exceeded or
b. The work will not be marked above the word limit.
3. Assignments are to be submitted through Turnitin in Blackboard, only one submission attempt is possible.
4. Students may request an extension to the stipulated due date in exceptional circumstances only and where supporting documentation can be offered. Such requests must be made via the University’s online request centre no later than 1 week prior to the due date. Requests received on or after the due date will not be considered.
5. Assignments should be submitted by 23.59 local time in the students’ country of residence. Where an assignment is late without an agreed extension, the following rules will apply without prejudice:
a. Up to 1 week late – 10% penalty.
b. From the 8th day late to the end of the second week – Assignment will be capped at the lowest possible passing grade.
c. Assignments received after the 2 weeks will be zero graded.
(N.B - Where 10% is stated above, in practice this means that 10 points will be removed from any grade as each assignment is graded out of 100. An assignment graded at 50 which receives a 10% Penalty with therefore have a final grade of 40)
6. This assignment contributes to 40% of the overall module grade.
7. Before submitting your assignment, please ensure that it is properly referenced, to guard against accusations of malpractice. Guidance on referencing can be found by clicking on the link below and choosing “Harvard Referencing Guide”
http://www.bangor.ac.uk/library/help/guides.php.en
8. The pdf has to be entitled with the Student ID number of each student of the group. The front/first page of the assignment has to highlight the name and ID of the student.
9. The data provided on the blackboard. Students need to reply the questions demanded in their report depending on the number of group is even or odd ( Like Group 1 is odd)
Additional information on avoiding allegations of malpractice can be found in the Student Handbook.
The copying of material extends to the use of essay mills and AI technology such as ChatGPT. You are reminded that the use of such services to generate work in substitute of your own original
contributions contravenes Bangor’s Academic Integrity policy. Any detected attempt to use such tools will also result in referral to the Business School Academic Integrity Officer.
If any of the above rules are not satisfied, there is a penalty of 10%.
Finally, you cannot submit the assignment by yourself if you are assigned with group there is penalty of 50%. To the end, each leader has to submit it with the name of the Group. Like group 1, 2 etc.
You are expected to write the report (aim for 2000 words +-10%) to read, look and feel like a FT
article (20% of the marks). The do-file of STATA has to be in the appendix of the report. Groups that numbered with odd number, they are focusing on developing countries. The number of groups with even number are focusing on developed countries. For instance Group 1 is focusing on developing countries. ( To help: (https://datahelpdesk.worldbank.org/knowledgebase/articles/906519). The
variables are taken fromhttps://www.rug.nl/ggdc/productivity/pwt/?lang=en.
The report has to answer the following questions and data provided in Blackboard:
The Solow model predicts that growth rates depend on the starting level of GDP, the population
gTowthi = a+β1pop i+ εi
Obtain estimates of the OLS estimators α and β for the regression only for the developed (developing) countries if your group number is odd (even) for the year 2010.
The growth rate is calculated as the average growth rate of real GDP ratio between 1970- 2015. All variables are in natural logs. See the variables definition below.
2) Add the variable investment and the GDP per capita of the year 1970 in your model and estimate it again.
Comment on the sign and significance of all the coefficient estimates. Outline the economic intuition underlying your results. Are they consistent with empirical literature? Explain.
3) For each of the following questions formulate a null hypothesis and test your equation:
. • population is the only determinant of growth
• The relationship between the investment and economic growth is equal to 0.3
• GDP in 1970 and population have the same effect on economic growth.
4) After investigating the related empirical literature, add an extra variable from the dataset that you have not used in your model. What are the estimates? Are they line in it?
5) Test for Heteroskedastisity. If it is present, correct it.
6) Divide the countries of your sample in regions/continents. Estimate your model adding the continents’ variable in the model. Do you find any differences? Explain.
7) Interact the continent dummies with the variable investment. Comment and Interpret the coefficients.
8) Discuss whether endogeneity issues are present. If yes, how you can solve them, discuss using the existing literature.
9) Run your model including all the years from 1970 to 2019. Illustrate and discuss the model and the suitable estimation method you used. Do you find any different estimates from the question (2)? Explain.
10) Generate a dummy for capturing COVID-19 for the period 1970-2022. Then run regressions with Pooled OLS, Fixed effects model and random effect model. Discuss the results and which is the most appropriate model?
