Econometrics is a field of study that combines economic theory with statistical methods to analyze and understand economic data. The specific topics taught in econometrics courses in university may vary depending on the level and focus of the course. Here are some common topics taught in schools such as LSE, UCL, Oxford, and Cambridge:
The linear regression model and its assumptions:
You will learn the basic structure of a linear regression model, including the relationship between the dependent and independent variables, and the assumptions that must be met for the model to be considered "well-behaved" (such as linearity, independence of errors, and homoskedasticity).
Estimation methods for linear models:
This topic covers the various methods that can be used to estimate the parameters of a linear regression model, including the classical least squares method, and more advanced methods such as maximum likelihood estimation.
Hypothesis testing and model selection:
This topic covers the use of statistical tests to evaluate the goodness-of-fit of a regression model and to test hypotheses about the model's parameters. It also covers methods for selecting the best model among a set of candidate models.
Residual analysis and model diagnostic checking:
You will also learn about techniques for analyzing the residuals of a regression model to check for violations of the model assumptions and to identify possible sources of model misspecification.
Time series econometrics:
This topic covers the use of econometric techniques to analyze time series data, including methods for dealing with non-stationarity, serial correlation, and heteroskedasticity. It also covers advanced topics such as ARIMA models and cointegration.
Panel data econometrics:
These are econometric techniques used to analyze data that varies both across time and across individuals or groups, such as data on firms or households. It covers methods for dealing with the correlation between observations within groups and the choice of fixed effects or random effects models.
Nonlinear models:
This topic covers the use of econometric techniques to analyze data in situations where the relationship between the dependent and independent variables is nonlinear, such as logit and probit models, and survival analysis.
Advanced topics such as endogeneity, instrumental variables, and dynamic panel data models:
These topics cover more advanced econometric techniques that are used to deal with specific problems that may arise in empirical research, such as endogeneity (when a variable is correlated with the error term), and dynamic panel data models (models that include lagged variables)
Software packages such as STATA, EViews, R and Python:
This covers the use of software packages that are commonly used in econometrics research, such as STATA, EViews, R and Python. These software packages are used to implement the econometric techniques covered in the course, and students will learn how to use them to estimate models, perform hypothesis tests, and generate tables and figures for their research.
These topics are essential for students to learn as they will provide them with the necessary tools and skills to analyze and interpret economic data and conduct research in various fields of economics.
