What is this?

This document details our college teaching arrangements for Quantitative Economics (QE) at Lady Margaret Hall. It will be updated periodically, so please make sure to check back regularly. The date of the current version is given above.


QE teaching at LMH is split across two academic years. Eight “regular” classes will take place in TT of your second year, and four revision classes will take place in HT of your third year. To keep my life simple, this document applies to all classes that take place in a given calendar year. In other words: the material listed below under classes applies to current second years while the material listed under revision classes applies to current third years.

Blog Posts

I’ve written some blog posts covering topics from QE or slight extensions of the course material. If you have any questions about them, leave a comment!


During TT of your second year, you will have eight QE classes: one each week.

Logistics: TT 2024


Class 1 - Prob/Stats Review

Class 2 - Regression I

Class 3 - Regression II

Class 4 - Regression III

Class 5 - Endogeneity I

Class 6 - Endogeneity II

Class 7 - Time Series I

Class 8 - Time Series II


You will take a three-hour collection (mock exam) at the beginning of MT in your third year. I will discuss how best to prepare for the collection during our final class in TT of your second year. Because your collection will be based on the most recent QE exam paper, to get the most out of your collection you should avoid peeking at the corresponding exam paper in advance.

Revision Classes

During HT of your 3rd year, you will have four QE revision classes: one every other week. During the revision classes I will go over past exam questions, focusing on those from the most recent years. A list of the problems I suggest that you prepare for each class follows below. I will take requests from these problems during my classes, emphasizing the more recent problems. Each class will begin with a quiz based on the associated course material for that class, so you should make sure to review in advance.

Logistics: HT 2024

Thursdays of HT weeks 1, 3, 5, and 7 from 3-5:30pm. Weeks 1, 3, and 7 will be in the Amanda Foreman room; Week 5 will be in the Lyttleton Room.

Past Exam Solutions

Exam papers for 2014-2022 are posted on the QE canvas site, along with solutions for 2014-2019. Because older exams are less relevant to the current version of the course, and given that you have solutions to them, I will focus on exams from 2020 onwards in the revision classes.

Class 1: Prob/Stats

For Discussion

  • MT 2023 Collection, Problem 1: cdf and pmf of a discrete RV
  • MT 2022 Collection, Problem 1: cdf and pmf of a discrete RV
  • MT 2021 Collection, Problem 1: higher moments of a Uniform(-1,1) RV

Extra Practice

  • MT Collection 2019, Problem 4: two sample t-test for an RCT
  • MT Collection 2018, Problem 4: Bernoulli moments, test for proportion
  • TT Exam Paper 2017, Problem 4: conditional expectation, independence vs. mean independence; best predictor vs. best linear predictor. This question was omitted from the MT 2017 collection; I’m not sure why.
