There are a lot of suggestions that the code and data be required to publish.
Sorry guys, but that hasn't worked so far: the economics journal _Journal of Money, Credit and Banking _, which required researchers provide the data & software which could replicate their statistical analyses, discovered that <10% of the submitted materials were adequate for repeating the paper (see "Lessons from the JMCB Archive", Volume 38, Number 4, June 2006).
