This page describes the Department’s expectations about students’ mathematical knowledge at two points in their course of study: upon entering the program, and before taking the preliminary exams at the end of the first year.
While most of the material in these classes is useful for graduate work in economics, it is not always clear to incoming students which topics covered in these classes are most important to review before graduate coursework begins. We list five key topics below. Two useful references on these topics are:
[DS] M. H. DeGroot and M. J. Schervish, Probability and Statistics. 3rd ed. Boston: Addison- Wesley, 2002.
[SB] C. P. Simon and L. E. Blume, Mathematics for Economists. New York: Norton, 1994.
1. Basic probability theory (discrete and continuous random variables, conditional
probability, expectations, the weak law of large numbers, the Central Limit Theorem) and
basic mathematical statistics (point estimation, interval estimation, hypothesis testing). [DS,
various chapters].
2. Geometric representation of vectors and functions in n-dimensional space [SB, Ch. 10 and
Sec. 13.2].
3. Differentiation of multivariate functions [SB, Sec. 14.1-14.6].
4. Unconstrained optimization, and equality constrained optimization via the Lagrange
multiplier method [SB, Ch. 17 and Sec. 18.2].
The last item is not covered in all undergraduate calculus sequences. Still, we advise
students to study this topic before classes begin.
5. Basic convexity [SB, Sec. 21.1-21.3].
Are you a UW Madison student looking for a recommended set of courses? Take a look at the academic path document provided by the Department of Economics Undergraduate Program. The set of courses suggested to prepare for graduate school in economics will help you acquire the mathematical knowledge that can ease the transition into a Graduate Program in Economics. You can see the description of the courses at the Department of Mathematics’ Undergraduate Course Description page.
By the time first-year course work is over, students have learned a wide range of
mathematical techniques for economic analysis. Below, we list some fundamental topics that
students should master before taking the micro and macro prelims. As additional references,
we mention two standard textbooks for the macro curriculum and one for the micro
curriculum:
[S] T. J. Sargent, Macroeconomic Theory. 2nd ed. San Diego: Academic Press,1987.
[SL] N. L. Stokey and R. E. Lucas, Recursive Methods in Economic Dynamics. Cambridge:Harvard University Press, 1989.
[MWG] A. Mas-Colell, M. D. Whinston, and J. R. Green, Microeconomic Theory. New York:Oxford University Press, 1995.
N.B.: The Department does not merely expect students to be able to recite the basic results
from each of the areas listed below. Rather, we expect students to possess a working knowledge
of each topic on the list. This means, for example, that students should be able to recognize
situations in which the various techniques are relevant, and should understand how to put the
techniques to use.
1. Constrained optimization, the Kuhn-Tucker conditions, and concave maximization [SB,
Ch. 18, 19, 21, and 22; MWG, Sec. M.K].
2. Comparative statics, implicit differentiation, and the implicit function theorem [SB, Ch. 15
and 22; MWG, Sec. M.E and M.K].
3. Mathematics for time series analysis: difference equations, linear regression, Wold
representation for time series, spectral analysis [S, Ch. 9-11].
4. Dynamic programming [SL, various chapters].
5. Homogeneous functions [SB, Sec. 20.1; MWG, Sec. M.B].
6. The Envelope Theorem [SB, Sec. 19.2; MWG, Sec. M.L].
7. Compactness and the Weierstrass Maximum Theorem [MWG, Sec. M.F].
8. The Theorem of the Maximum [MWG, Sec. M.K].
9. Basic fixed point theory, especially Brouwer’s Theorem [MWG, Sec. M.I].
10. The Separating Hyperplane Theorem [MWG, Sec M.G].
