“…The exception occurs in the very particular case in which the returns to scale in the production of legal arguments are decreasing and sufficiently low (Farmer and Pecorino, 1999). 3 However, in this case, the introduction of realistic considerations, such as, for example, asymmetries between individuals, outside options or other aspects is analytically intractable (Dari-Mattiacci et al, 2015). Analytical tractability can be recovered by assuming constant returns to scale in the production of legal arguments, but then, as explained, no case reaches trial under the English system, which is counterfactual; 4 thereby restricting to a great extent the generalized application of the "rent-seeking" CSF, and questioning whether this approach to litigation is complete enough.…”
