Ergodicity in Economics: a Decision theoretic evaluation

Author

  • Andreozzi, Luciano

Abstract

Peters (2019) presents a new version of the St. Petersburg paradox that allegedly reveals a weakness of orthodox decision theory under uncertainty. I use a variant of Rabin (2000) calibration theorem to show that the new paradox only arises because the author implicitly assumes an unbounded utility function for money. I also assess the author's claim that orthodox decision theory is wrong in insisting on utility functions to be bounded and find it unconvincing.
