Material for students

My guidelines for thesis supervision (MSc). Please, read before contacting me.

I created a template for students who want to get started with LaTeX. Read the "Getting Started" part of the wikibook first. Then have a look at the following files: .tex (with explanations of common usage), .bib (bibliography), example graphic, .pdf (the compiled output), plain .tex template. If the use of BibTeX for citations is unclear, check Martin Osborne's guide.

I created some jupyter notebooks that explain how you can make professionally looking plots, numerically solve maximization problems and numerically solve (systems of) equations. I think all of this can be extremely helpful when writing a seminar paper or a thesis. The backend for all this is the julia programming language but no prior knowledge of programming is required. The notebooks can be found here.

Software and IT:

How to use OpenPGP with Thunderbird or using webmail (like gmail etc.).
For graphs, I use the tikz package. Jacques Crémer has written an excellent mini-introduction to tikz. qtikz is a nice little software that makes graph creation with tikz even simpler by providing some WYSIWYG feeling.
For writing games, the packages provided by Martin Osborne are helpful.
I use julia to solve examples numerically. (In the past, I also used python.)

Miscellaneous

Code

I have written some python code to solve school choice matching problems as well as some simple programs to solve finite strategic form games of complete information. Both can be found on github. Neither is computationally fast as both were only made for teaching purposes. Check the .org files as they contain lots of explanations.

For some of my papers, I used julia for numerical analysis.
