“…A related class of models links firm dynamics in export markets to learning about unobserved demand (Albornoz et al, 2012;Chaney, 2014;Eaton et al, 2014;Ruhl and Willis, 2014;Timoshenko, 2015a,b;Arkolakis, Papageorgiou, and Timoshenko, 2015). While the microfoundations of the learning process vary across models, this body of work makes it possible to rationalize the age-dependence of export growth (conditional on size) observed in the data.…”
