While much research has emphasized the importance of firm resources for early internationalization, very few studies have theorized and empirically tested the effect of resource characteristics on early internationalization (Keupp & Gassmann, 2009). Moreover, most of these studies have pointed out the importance of resource availability (or the existence of slack resources), and largely overlooked the importance of the configurations of existing resources to the internationalization process. These studies have argued that slack resources buffer organizations from external shocks, and provide flexibility (Hannan, 1998). However, given the limited slack resources new ventures almost always have, we focus on the mobility or the flexibility of the available resources, not on the amount of resources. We specifically ask: whether and how does the mobility of available resources affect early internationalization of new ventures?
