The survival of new exports is key for underpinning the dynamics of exports growth. In this paper, we explore whether agglomeration of exporters enhance duration of export flows at the firm-product-destination level using transaction level data for the universe of exports in Colombia between 2005 and 2011. We find that both the presence and size of agglomerations increase the survival rate of trade flows, defined by the triple firm-product-destination. This agglomeration effects seems to be related with flow specific spillovers and are highly concentrated across space. The effects tend to be stronger as firms perform similar product-destination export activities. Also the effects are larger for differentiated products where uncertainty about demand is more prevalent.

出口商的集聚与出口流量的存续：来自哥伦比亚的经验证据

新出口的生存是支撑出口增长动力的关键。在本文中，我们使用2005年至2011年哥伦比亚的整个出口范围的交易级别数据，探讨了出口商的集聚是否在企业-产品-目的地一级提高了出口流动的持续时间。我们发现，集聚的存在和规模都在增加贸易流的存活率，由三重公司产品目标定义。这种聚集效应似乎与特定于流动的溢出有关，并且高度集中在整个空间中。随着公司执行类似的产品目的地出口活动，其影响趋于增强。此外，对于需求不确定性更为普遍的差异化产品，其影响更大。
