Exporting is an important path to boost firm growth and performance (Autio et al., 2000; Bloodgood et al., 1996). Despite the importance of understanding the antecedents of firms’ exporting behavior, few studies have focused on how slack resources—those resources firms possess in excess of resource demands from current business—influence firms’ exporting behavior (Tseng et al., 2007). On the one hand, slack resources may provide the means necessary to cross borders and allow firms to compete in international markets with less binding constraints. This is expected to stimulate firms’ exporting activities. On the other hand, slack resources may shield firms from external pressures, which reduces firms’ incentives to adapt to environmental pressures and to engage in risky projects. This is expected to hamper firms’ exporting activities. The goal of this study is to examine how different types of slack, including financial slack and human resource slack, influence firms’ exporting behavior, including the decision to export, the export intensity and the export diversity.
