 One way to capture these rough intuitions about the degree and source of factors that influence prices is to appeal to antecedent notions of justice. In other words, whether influence of pressure, information and other factors on price is fair depends on whether the distributions of information and pressure among the parties are just. In this case, the fair price would not be that which excludes all influence from pressure or informational asymmetries, but instead the price that we would find in a just market. Of course, there are many competing conceptions of justice. However, the next procedural account offers structural conditions that are, in principle, compatible with a wide range of approaches to justice.
