Case study
Energy plays a central role in economic development, industrial productivity, and improvements in living standards. At the same time, rising energy demand and dependence on fossil fuels contribute significantly to carbon emissions and climate change. In response, many countries, including Malaysia, have increased focus on renewable energy adoption as part of broader sustainable development and energy transition strategies.
Renewable energy can contribute to long-term economic growth, improve energy security, reduce environmental degradation, and support climate commitments. However, the effectiveness of renewable energy policies may be influenced by other macroeconomic and structural factors such as income growth, electricity demand, urbanization, and carbon emissions. Understanding how these variables interact is important for evaluating policy effectiveness and informing future development planning.
You are interested in learning more about the determinants of renewable energy dynamics and their relationship with economic growth in Malaysia. To understand this better, please do some reading on these topics before you start the assignment. The variables you need to use are given below. The full dataset is available in Appendix 1_EnergyMalaysia on the assessment page.
Variables:
a) Renewable energy consumption (% of total final energy consumption).
b) GDP per capita (constant 2015 US$).
c) Electric power consumption (kWh per capita).
d) CO₂ emissions (metric tons per capita).
e) Urban population.
Question 1.A
Understanding deforestation: Preliminary work
Work Required: Prior to answering all the questions, you are expected to clean the data set in the excel sheet by removing all missing observations (including values recorded as ..)., converting all the values of the variables to LN (Natural Logarithm) form, Renaming variables using one word or underscore format for example (LN RenewableEnergy or LN_RenewableEnergy).
In preparing your answers to all questions (from question 2.A onwards), only use the cleaned data. Note that you are required to save the cleaned data set and submit it as a separate file with your assessment.
Question 2.A
Performing Diagnostic Tests
Work Required: Provide a comprehensive explanation and application of the following diagnostic tests using the cleaned dataset:
- Multicollinearity Diagnostic Test: Evaluate whether relationships among Renewable energy consumption, GDP per capita, Electricity consumption, CO₂ emissions, Urban population create multicollinearity issues and interpret the Correlation matrix, VIF and tolerance statistics, and any problematic relationships.
- Serial Correlation Test: Conduct appropriate serial correlation diagnostics (for example Durbin-Watson or Breusch-Godfrey tests). Interpret whether time-dependent autocorrelation exists in the economic-environmental data and discuss implications.
- Heteroskedasticity Test: Perform and interpret heteroskedasticity diagnostics. Discuss whether unequal variance affects coefficient reliability, inference, and forecasting accuracy.
Please, insert all the output tables generated through SPSS. Justify your answer with evidence from a minimum of two (2) relevant literature for each test, to justify the importance of these tests.
Question 3.A
Addressing Inconsistencies in the Data
Work Required: For each issue identified in Question 2A, suggest at least one corrective measure for each test. Justify your answer with evidence from a minimum of two (2) relevant literature for each suggestion.
Please ensure to address the following aspects: quality of sentencing and grammar, usage of clear structure, relevance of your justifications.
Question 4.A
Applying distributed lag models
Work Required: You are expected to Introduce the concept of distributed lag models and explain how they can be applied in economic and environmental analysis.
In preparing your answer you must implement a distributed lag model on the Renewable Energy Consumption and GDP per capita for the last 3 years. Analyze the lagged short-run and delayed impacts of renewable energy on GDP and provide at least two (2) insights.
Please, insert all the output tables generated through software in your answer. Justify each insight with evidence from a minimum of one (1) relevant literature and ensure to address the following aspects: quality of sentencing and grammar, usage of clear structure.
Question 5.A
Benefit and risk assessment of dynamic model
Work Required: You are expected to explain how dynamic models could help forecast future GDP per capita using historical data and relevant predictors such as, renewable energy consumption trends, urban population growth, electricity demand, or CO₂ emissions patterns.
In preparing your answer you are expected to discuss three (3) benefits of dynamic models and consider any three (3) challenges/risks that may arise in implementing dynamic models.
Please, justify your answer with evidence from a minimum of two (2) relevant literatures and ensure to address the following aspects: quality of sentencing and grammar, usage of clear structure.
