The authors also address empirical gaps affecting the role of dyadic business relationships (BRs) (customers/suppliers/research institutions/competitors) and business networks and their effect on international performance. Finally, the authors research whether insiders’ firm-specific advantages have a stronger effect on international performance than outsiders’.engjournal articlehttps://doi.org/10.1108/IMR-04-2014-0142restricted accessBusiness relationshipsUppsala modelInsidershipInternational performanceLiability of outsidershipEconomía internacionalEmpresas5310 Economía Internacional5311 Organización y Dirección de Empresas
