This document discusses uncertainty in marketing mix strategies for business-to-business export markets. It presents hypotheses about how international entrepreneurship and networking abilities can help reduce uncertainty and improve marketing mix assessments. A survey was conducted of German companies operating in emerging markets to test the hypotheses. Structural equation modeling found support for hypotheses about international entrepreneurship and networking reducing uncertainty and enabling better adaptation of pricing and promotion strategies. Product adaptation and sales structures were not significantly impacted by uncertainty. The findings provide implications for managers on actions to reduce uncertainty like market research and some standardization versus adaptation of marketing mix elements.
