You can download my lecture slides for this course using the links below. All documents are in .pdf format. Most modern web browsers are equipped with an Acrobat reader to access these files. Visit Adobe for more details.

Course Outline

The course outline containing all the details on this page is available here. This is the document you were sent in the introductory pack during the summer. You should also have been sent the Preparatory Work document, which provides pre-course reading along with exercises and answers.

Course Objective

This course is intended for those taking the M.Phil. in Economics at Oxford University. The course covers the main mathematical pre-requisites for the M.Phil. All incoming students for the M.Phil., unless they have a very good background in mathematics and statistics, are advised to attend. PRS students may also find the course useful, and are welcome to attend if they wish.

Teaching

This week's lectures are on the following days:

  • Tuesday 29th September: 9.15 - 11.50
  • Thursday 1st October: 9.30 - 11.50
  • Friday 2nd October: 9.30 - 11.50

There will be a twenty minute coffee break at 10.30 each day. The first lecture takes place in the Lecture Theatre at the Manor Road Building. The remaining lectures will be held in Seminar Room A. The associated classes take place in the Lecture Theatre on the first day and Seminar Room A subsequently, on the same days as the lectures, between 4.30pm and 5.30pm.

Exercises

Exercises will be distributed during the lectures. You can also download Exercises 1-3 together in a single file. These will be reviewed in the afternoon class, so you should work on them during the day. Solutions will be distributed during the class, and you will be able to download Answers 1-3 after the course is over.

Contact

I can be reached at Trinity College or at the Department of Economics. Email is best.

Reading

There are many good introductory textbooks: for the first four topics, you may wish to try:

  • Simon, C. P. and Blume, L. (1994) Mathematics for Economists, Norton, New York NY.
  • Chiang, A. C. and Wainwright, K. (2005) Fundamental Methods of Mathematical Economics, 4th Edition, McGraw-Hill, New York NY.
  • Sundaram, R. K. (1996) A First Course in Optimisation Theory, CUP, Cambridge.

For probability and distributions, try:

  • Casella, G. and Berger, R. L. (2001) Statistical Infererence, 2nd Edition, Duxbury, Belmont CA.
  • Greene, W. H. (2002) Econometric Analysis, 5th Edition, Prentice Hall International, London.
  • Spanos, A. (1986) Statistical Foundations of Econometric Modelling, CUP, Cambridge.

A more advanced treatment of all five topics may be found in:

  • Corbae, D., Stinchcombe, M. B., and Zeman, J. (2009) An Introduction to Mathematical Analysis for Economic Theory and Econometrics, Princeton University Press, Princeton NJ.

Topic Outline

The first week's lectures cover five topics. A brief guide to the content follows.

Topic 1: Sets and Sequences

Sets and sequences: open, closed, bounded, compact, and convex sets, supremum and infimum, convergence, continuity.

Topic 2: Functions of One or More Variables

Intermediate Value Theorem. Bolzano and Brouwer fixed point theorems. Taylor and Maclaurin expansions, mean value theorem, L'Hopital's Rule. Weierstrass' theorem, homogeneous functions, Euler's theorem, homothetic functions, repeated integrals, differentiating integrals.

Topic 3: Equations and Matrices

Equations and matrices, linear systems, Cramer's rule, rank, eigenvectors and eigenvalues.

Topic 4: Comparative Statics

Calculus with several variables, total differential and derivative. Implicit differentiation, implicit function theorem, comparative statics.

Topic 5: Probability and Distributions

Probability and some important distributions (Poisson, log-Normal, gamma), moments, Jensen's and Chebychev's inequalities, conditional probability, Bayes' theorem.
