In order to bridge the gap between theory and practice in the Financial Engineering community it is important that financial models demonstrate sound engineering features of reliability and robustness and apply a repeatable process. A review of 47 journal and conference financial engineering papers from 1990 to 2013 reveals a large gap between theory and practice persists. This paper surveys these papers in terms of repeatability, reliability, realism, and robustness. It offers strategies for bridging the gap between theory and practice.
