I had a twitter exchange with Luis Garicano that was prompted by that post. It illustrates what my private conversations have been like.
To make this exchange more readable, I have tried to order it in threads, with each response indented just below the tweet that seems to have prompted it. As a result, the order of the tweets is slightly different from the actual chronological order. The date is a link that should take you back to the actual tweet.

Luis, pls look at presentation of bounded model in Lucas-Moll paper. Am I missing something? — Paul Romer (@paulmromer) August 1, 2015
Sure unbounded support not a great assumption.But in whole career Lucas less guiltily of ‘mathiness’ than 99% of his peers. — Luis Garicano (@lugaricano) August 1, 2015
OK to consider unbounded if done transparently. Problem is calling model with unbounded support for t != 0 a bounded model. — Paul Romer (@paulmromer) August 1, 2015
agree that should have been transparently laid out. — Luis Garicano (@lugaricano) August 1, 2015
What freshwater sympathizers say: “everybody does it.” “Even more” But where are the examples from outside freshwater camp? — Paul Romer (@paulmromer) August 1, 2015
