Krzysztof Pytka


I'm a PhD candidate in Economics Image of a Krzysztof Pytka at the European University Institute in Florence, Italy. I specialize in Macroeconomics, in particular in 1. consumption; and 2. search theory. My technical interests also cover computational economics and (applied) statistical learning. For some time, I've focused on incorporating frictions in the purchasing technology into the standard incomplete markets model.


  1. Shopping Effort in Self-Insurance Economies [Job Market Paper]
  2. Lotteries in Equilibrium Price Dispersion
  3. General Equilibrium Theory of Shopping, Consumption, and Price Dispersion (jointly with Greg Kaplan)
  4. Labor Market and Business Cycle: Expansion vs. Contraction
  5. Shape-Preserving Chebyshev Approximation of Multivariate Functions


People who can say something more about my research agenda (and me):

  1. Árpád Ábrahám (EUI);
  2. Piero Gottardi  (EUI);
  3. Greg Kaplan (UChicago);
  4. Mark Aguiar (Princeton).


You can find my CV here.

  2. Advanced Statistical Learning in R/S-Plus [MA course @SGH];
  3. Introduction to Econometrics [BA course @SGH];

In my free time I (used to) write for Hummus Œconomicus, a Polish popular-science blog about economics. Here you can find my posts (sadly only in Polish).

If you're curious about the pronounciation of my given name it goes by [kʂɨʂt̪ɔf] in IPA. But Christoph is totally fine with me.
