Learning By Exporting: Evidence Based On Data Of Knowledge Flows From Innovation Surveys In Estonia
This paper studies learning-by-exporting, based on survey data of knowledge flow indicators. Most of the earlier related papers investigate the effects of exporting on productivity of firms, and often find little evidence of learning effects. This study looks more in detail into the mechanism of these effects. It investigates whether exporting is associated with increase in intensity of knowledge flows to the firm from the firm's clients, relative to other knowledge sources. The author uses measures of learning about the new technologies from two pooled innovation surveys and firm level exporting data of manufacturing firms in Estonia. Unlike the majority of earlier studies that use productivity data, the author finds evidence consistent with learning-by-exporting.
