Sharpen your argument
A student regresses hourly wages on years of schooling using cross-section data and finds a large positive coefficient. They conclude that an extra year of schooling causes wages to rise by that amount. What is the strongest objection?
Name the assumption being relied on. A causal reading of a regression coefficient requires the regressor to be uncorrelated with the error term.
If those omitted factors also affect schooling, the regressor is correlated with the error, which is endogeneity. The estimate mixes the causal effect with the influence of whatever was left out.
Say what would address it. An instrument correlated with schooling but not with the omitted determinants, or a research design that generates variation in schooling for reasons unrelated to ability.
The weaker choice: Objecting on sample size or functional form. Both are real issues in other settings and neither is the problem here: a larger sample estimates the same biased quantity more precisely, and logging wages changes the interpretation without touching the identification. Endogeneity is a problem of what the estimate means, not of how noisy it is, and that distinction is what the module is testing. watch this!

Overview
What ECNM10052 is, and where it sits
Essentials of Econometrics is the module that ensures every Edinburgh economics Honours student has a working command of modern empirical economics. The catalogue frames it in career terms as much as academic ones: these are skills for later stages of the programme and for many future contexts.
The syllabus works through regression twice. First with cross-section data: the two-variable model, multiple regression, functional forms, dummy variables, then the two problems that make applied work hard, heteroskedasticity and endogeneity. Then with time series data: autocorrelation, trends, seasonality, stationarity and weak dependence, spurious regression, unit roots and cointegration. Panel methods are introduced briefly at the end.
The delivery is built for practice rather than exposition. Weekly lab sessions and tutorials run alongside lectures from week 2, with computer exercises for learning-by-doing and tutorial exercises for problem solving and interpretation. The published hours make the point: 20 lecture hours against 27 hours of tutorial and supervised lab time combined.
Always treat your own course outline and the exam timetable as authoritative.
Difficulty & time commitment
Is ECNM10052 hard, and how much time does it take?
ECNM10052 is manageable if you keep a weekly rhythm and treat the back half as the main event. The pattern is consistent: it starts gently and steepens, and the heaviest assessment is the part that separates grades.
The difficulty curve and the assessment weighting point the same way: the back half is harder and worth more. Front-loading effort there is the highest-return decision in the module.
Is this module for you
Who tends to do well, and who tends to struggle
You will likely do well if
- You do the lab exercises yourself rather than following along; the project assesses exactly that.
- You are comfortable holding an assumption in mind and asking whether it plausibly holds.
- You keep the December exam in view from week one, since it is 75% and it arrives early.
- Your statistics from second year is still fluent, because the module builds on it immediately.
You may struggle if
- You treat econometrics as a set of commands to run. The examinable content is the reasoning about identification.
- You defer the time series material; it arrives late and is examined in full.
- You skip labs. Twenty-seven hours of tutorial and lab time exists because the skills are practical.
- You want a light Honours option. This is the technical core.
- For every estimate you produce, write one sentence on what would have to be true for it to be causal.
- Keep a list of the standard endogeneity stories: omitted variables, simultaneity, measurement error, selection.
- Rehearse reading regression output out loud, including the standard errors, which is what the exam questions imitate.
- In time series, always check stationarity before interpreting anything; spurious regression is the trap the topic exists to teach.
Syllabus
The 9 topics, topic by topic
The exam-weight marker on each topic shows where the marks concentrate. The amber topics carry the highest exam weight.
T1 · The two-variable regression model
Cross sectionFitting and interpreting a single-regressor relationship, and what the estimates are actually estimating.
T2 · Multiple regression
Cross sectionAdding regressors, and the ceteris paribus interpretation that is the whole point of doing so.
T3 · Functional forms and dummy variables
Cross sectionLogs, quadratics and interactions, plus encoding categorical information so the coefficients mean what you think.
T4 · Heteroskedasticity
Cross sectionWhen the error variance is not constant: what breaks, what does not, and what to do about it.
T5 · Endogeneity
Cross sectionThe central problem of applied economics: when a regressor is correlated with the error, the estimate is not the causal effect. Everything else in the module is downstream of understanding this.
T6 · Autocorrelation, trends and seasonality
Time seriesWhat changes once observations are ordered in time and no longer independent.
T7 · Stationarity, weak dependence and spurious regression
Time seriesWhy two unrelated trending series can appear strongly related, and the conditions under which time series regression is valid at all.
T8 · Unit roots and cointegration
Time seriesTesting whether a series has a stochastic trend, and when a relationship between non-stationary series is nonetheless real.
T9 · Introduction to panel data
PanelA brief look at methods that exploit repeated observations on the same units.
How it's assessed
Assessment structure
| Component | Weight | Format & timing |
|---|---|---|
| Degree exam | 75% | Written examination, 120 minutes, held in the December diet. December. Three quarters of the mark in one paper. |
| Project | 25% | Empirical project drawing on the computing, data handling and interpretation skills developed in the weekly lab sessions. Semester 1. The only coursework component, and the place where the applied skills are actually assessed. |
- The published components sum to 100. No separate hurdle is published for this module.
- One 120-minute written paper in the December diet, carrying 75%.
- Calculator policy: Not stated in the course catalogue entry.
This is an exam-cram module. With the exams at 75% of the grade and the degree exam alone at 75%, your result is overwhelmingly decided by how well you perform under time pressure. Three quarters of the mark in one paper.
How to actually pass it
A weekly rhythm, two checklists, and the traps to avoid
The module rewards consistency over cramming, and practice over re-reading. Here is the loop that works, then what to have nailed before each exam.
The weekly loop
Before the mid-semester checklist
- The two-variable and multiple regression models, and the ceteris paribus interpretation
- Functional forms and dummy variables, including interactions
- Heteroskedasticity: what it breaks and what it does not
- Endogeneity, stated precisely rather than gestured at
Before the final heaviest topics
- All cross-section material, since the December paper is the whole exam
- Autocorrelation, trends and seasonality
- Stationarity, weak dependence and spurious regression
- Unit roots and cointegration
- The introduction to panel methods
The mistakes that cost marks
Reading a coefficient as causal by default. Identification is an assumption about the error term, not a property of the estimator. This is the module's central lesson.
Regressing trending series without checking stationarity. Spurious regression produces impressive statistics from unrelated data, which is why the topic is examined.
Fixing heteroskedasticity and thinking the estimate is now causal. Robust standard errors fix inference, not identification. The two problems are independent.
Treating dummy variable coefficients as averages. They are differences relative to the omitted category, and misreading them is a reliable source of lost marks.

Formula & concept sheet
The vocabulary and formulas you must own
- Ordinary least squares
- The estimator that minimises the sum of squared residuals; the starting point of the module.
- Ceteris paribus interpretation
- Reading a multiple regression coefficient as the effect of one regressor holding the others fixed.
- Functional form
- The shape imposed on the relationship, through logs, quadratics or interactions, which changes what the coefficients mean.
- Dummy variable
- A binary regressor encoding a category; its coefficient is a difference from the omitted category.
- Heteroskedasticity
- Non-constant error variance, which invalidates standard inference but not the estimator's unbiasedness.
- Endogeneity
- Correlation between a regressor and the error term, which breaks the causal interpretation of the estimate.
- Autocorrelation
- Correlation between errors across time, common when observations are ordered.
- Stationarity
- A series whose statistical properties do not change over time; the condition much time series inference requires.
- Spurious regression
- An apparently strong relationship between unrelated trending series.
- Unit root
- A stochastic trend in a series, which must be tested for before regression.
- Cointegration
- A genuine long-run relationship between non-stationary series.
- Panel data
- Repeated observations on the same units, allowing some unobserved differences to be controlled for.
