BA Modern History with Economics

Year of entry: 2024

Course unit details:Micro Econometrics

Unit code ECON30342 10 Level 3 Semester 2 Yes

Overview

This course unit makes use of the basic econometric tools learned in Econ20110 Econometrics and applies them to modern microeconometric issues. Microeconometrics is the application of regression techniques to estimating causal effects using cross-section or panel data sampled from microeconomic agents. The course will be of interest to those studying microeconomics or related areas (e.g. labour economics, public economics, and development economics) and will be useful to students who wish to pursue more advanced applied economics co-urses later in their career.

Aims

The aim of this course to further develop students' knowledge of modern microeconometric techniques, and so develop the tools required to analyse datasets covering relating to microeconomic units (individuals, households or firms) observed at a single point in time or over time multiple time periods. It focuses on causes of bias/inconsistency, and therefore non-causality, namely endogeneity. These causes are omitted variables, measurement error, simultaneity and self-selection.

Learning outcomes

After completing this unit, students will:

(i) be able to demonstrate a clear understanding of how the regression model is used when analysing cross-section data;

(ii) know how to use, and interpret the output from the econometric package Stata;

(iii) understand what is meant by a causal effect;

(iv) appreciate the various difficulties in estimating causal effects, and understand the way in which econometric methods, in combination with economic models, can address these difficulties when using cross-sectional and panel data.

Syllabus

1. Introduction: types of data; panel v (pooled) cross sections.

2. Causality and unbiased estimation:

• Wooldridge's MRL1-4 & multiple regression;
• Simple regression with RHS dummy: y on {1, d}. The analogy principle (estimation in the population);
• Consistency.

3. Endogeneity:

• Omitted variables bias (OVB), long and short regressions;
• Measurement error (ME);
• Simultaneity.

4. Selection bias, treatment effects, and the Potential Outcomes framework.

5. Inference (hypothesis testing)

• raditional inference (Wooldridge's MLR5 & MLR6);
• Heteroskedasticity and Robust inference;
• Clustering (Moulton formula only).

6. Modelling using Multiple regression.

• y on multi-category dummies (firm-size and earnings) and fitting a quadratic (graduate earnings differential and age).

7. Panel data and First Differenced Estimator (FD).

8. Policy Analysis and the Difference-in-Difference (DiD) estimator.

• Panel & Pooled Cross Sections. y on {1, d1, d2, d1d2}. Common Trends. Hetergeneous treatement effects.

9. The IV estimator (basics).

• The simple regression model: y on x with z as IV. 3 conditions for instrument validity(testable/assumptions). When z is binary (Wald estimator). Inference. Hausman test for endogeneity and weak IVs. Over-identified models (GIVE/2SLS). The Grouped Mean estimator. The LATE.

10. Regression Discontinuity (the RD estimator). [If time allows]
