Trial-Level Criminal Outcomes 

 With a coauthor, I am involved in a project which in part attempts to assess the effect of assigning judge A versus judge B to outcomes at the trial level in criminal cases.  I've begun a literature search on this, and it seems like most attention thus far has focused on the sentencing stage (particularly relating to the controversy over the federal sentencing guidelines), and that few authors have used what one might call modern or cutting edge causal inference thinking.  Can anyone out there help here?  I'm I missing important studies?
