## Course unit details:Quantitative Methods

Unit code ECON20222 20 Level 2 Semester 2 Economics Yes

### Overview

The aims of this unit are to:
The general purpose of this course is to provide students with a non-technical introduction to the basic methods of econometrics. The focus will be on:
1. enabling students to perform basic data handling (uploading, re-categorising, cleaning) in a statistical software and to implement the statistical techniques taught in the course in that software;
2. giving students a basic understanding and working knowledge of multivariate regression;
3. developing students’ understanding of the difficulties associated with drawing causal inference;
4. developing students’ understanding of popular techniques of establishing causal relationships;
5. understanding issues arising from non-stationary time-series and gain a beginning understanding of time-series modelling and forecasting
linking the teaching of techniques to real-life problems
Knowledge and Understanding:
At the end of this course students should be able to:
• Understand how the use of statistics and econometrics can inform substantive discussion
• Have obtained a firm understanding of summary statistics
• Understand the basic tenants of regression analysis
• Understand issues arising from non-stationary time-series
• Understand the difficulties in establishing causal relationships
• Understand popular techniques of establishing causal relationships
• Be able to handle complex dataset and perform basic data-cleaning tasks
Be able to perform statistical analysis in a software package (R)

### Syllabus

The exact syllabus may vary and the following is indicative

An Introduction to R and RStudio and Summary Statistics
Understanding the basic workings of R. Importing data. Basic data operations including summary statistics. How to fix problems. Slicing data in different dimensions and conditional summary statistics.

Multivariate Regression Analysis and Inference - and Applications in R
Assumptions and resulting properties of multivariate regression analysis. Omitted variable bias. Basic inference problem. Test statistics and their distribution under the null hypothesis. P-values. Assumptions and robust inference (as standard!). t-tests and F-tests.

Causal relationships - Selection issues and applications of regression models
An introduction to issues arising when attempting to establish a causal relationship. Introduce selection problems (on observables and un-observables). Understanding that regression helps when selection is on observables. Selection on unobservable as the source of difficulties.

Panel data and Difference in Difference - and Applications in R
Cross-Section or Panel structure of data. How to use Panel data to remove time-invariant unobservables.

Correlation, Causation and non-Stationarity in Time-Series Data
Understanding the characteristics of non-stationary data. Spurious regressions.

Economic forecasting - Understanding the pitfalls
Use Surveys of Professional forecasters to understand variation in forecasts and uncertainty embodied in forecasts. Use AR(1) model to produce basic forecasts. Basic tenants of forecast evaluation. Evaluating forecasts for binary outcomes.

### Teaching and learning methods

Synchronous activities (such as Lectures or Review and Q&A sessions, and tutorials), and guided self-study
