> One of they authors addresses this in the comments on the OP: >> As we explain in the paper, this was a “design” parameter. We did not want to “adapt” the algorithm to each language to improve speed, because it will open the door to too many “uncontrolled variables” (how good a programmer in that language you are and so on). The only partial exception was with Mathematica for reasons explained in the paper. Sure, but this makes the paper less useful for answering the question, "which programming language should I use?" Or, "which programming language should I learn better?" But, yes, most economists are pretty bad programmers, so "which language should I use poorly?" is probably a useful question to answer.
