Study Notes
Course Objectives
- The course is an introduction to econometrics, focusing on econometric models.
- The main goal is to teach students the basic skills of model specification, estimation with real data, model testing, and fixing estimation problems.
What is the Econometric Model?
- An econometric model is one or more equations describing economic relationships between two or more economic variables.
- The model shows how a dependent variable is affected by independent variables, based on economic theory.
- The model has one dependent variable, while the independent variables can be more than one.
What is Econometrics?
- Econometrics is the quantitative analysis of economic relationships.
- It helps estimate the values of parameters (coefficients) that reflect the direction and strength of relationships.
Main Topics of the Course
- Model specification (today and in Chapter 1) and model estimation (four lectures)
- Model testing (Chapter 2)
- Model problems (Chapters 5 and 6)
Evaluation
- 30% midterm exam
- 20% attendance and assignments
- 50% final exam
Skills
- Knowledge and Understanding Skills: Demonstrate knowledge of key econometric techniques, and describe related topics in economics and business.
- Intellectual Skills: Analyze economic theories/models to solve problems/make decisions
- Professional Skills: Classify relevant data for economic/business relationship estimations, and use results for problem-solving/decision-making.
- General Skills: Effectively use econometric software (EViews) in projects.
Chapter One (Basic Concepts)
- Introduction to basic concepts in econometrics.
Definition of Econometrics
- Econometrics uses mathematics to analyze economic phenomena.
- Notable definitions of econometrics: Edward E. Leamer, Paul A. Samuelson, T.C. Koopmans and JR Stone
- Econometrics gives a quantitative form to economic theory and fills the gap between both
- Econometrics quantifies and analyzes real economic relationships.
The Use of Econometrics
- Specification (economic reality and estimation)
- Testing (relations/hypothesis testing based on economic theory)
- Forecasting (economic activity after correcting model estimation errors)
Model Specification
- To model commodity consumption, data on the following variables are needed:
- Price of the good (P)
- Price of substitutes (Ps)
- Disposable income (Yd)
- The relationship is represented as: C = f(P, Ps, Yd)
Model Estimation
- The aim is to measure the values of parameters in the model equation (e.g., a1, a2, a3, a4)
- Estimators provide estimates for these parameters using real data.
- The estimated equation includes an error term (equation 1-3)
Economic Hypothesis Testing
- Coefficients’ use can assist in testing hypothesis related to the model (e.g., whether a commodity is a normal good(increase in consumption with income))
Model Predictions/Forecasting
- Accuracy of predictions is influenced by the ability of the past to reflect the future.
Using Econometrics for Decision Making
- Example usage: forecasting commodity prices to guide sales estimations and manage prices.
- Useful in decision-making and policy-analysis by companies and governments.
Econometrics Approaches
- Different areas of research require different analysis methods.
- Clive Granger advocated for a specialized area of econometrics.
Quantitative Research Steps
- Specifying the model
- Collecting data
- Estimating the model
