Auto-seleção e aprendizado no comércio exterior das firmas industriais brasileiras

This article looks for to carry through an integrated analysis of the auto-selection hypotheses and learning by exporting hypothesis, offering elements for the quarrel on the recent promotion of exportations policies. We use here Brazilian manufacturing firms data from 2000 to 2006, from the Escritoire of Foreign Trade (SECEX), Annual Relation of Social Information (RAIS), and of the Annual Industrial Research (PIA). Beyond the descriptive analysis on the observable firm´s characteristics, this work has an econometrical analysis on the persistence, and the permanence firm´s determinants on the exporting activity. Its main results indicate that hysteresis in the exporting activity is stronger in micron and small companies, being such main categories responsible for the entrance flows and the exit in the external market. Aftermath, it exists a clear relation between entrance value, persistence and permanence in the exporting activity. However, as it was possible to observe this relation is not only based on by the auto-selection arguments, but also for the arguments related to the hypothesis of learning by exportations, as long as we obtain evidences of differentiated paths for of productivity premium before, and later, to the entrance in the external market.
