The purpose of this article is to present a biographical sketch of Lee C. Nehrt, who, in 1962, became the first person to obtain a PhD in International Business.

This study is mainly based on an in‐depth interview of Lee Nehrt followed up by several telephone and e‐mail interviews as well as e‐mail interviews of a number of Nehrt's former colleagues and students. In addition, Nehrt's published works were extensively reviewed and utilized.

The findings are reported in the form of a biography. In particular, the paper documents Nehrt's contribution to the emergence of international business as an important field of study, his role in internationalizing business curricula within the USA and in popularizing the American model of business education across the world. The paper also reflects on Nehrt's contribution to the Academy of International Business and his efforts in forging closer ties between international business academics and practitioners.

The dearth of biographical research in the international business discipline points to a need that has yet to be fulfilled. This is the first published article on Nehrt's life and career as a pioneering international business scholar.

This study aims to investigate the importance of relational and conditional knowledge by assessing how service and signaling competences affect manufacturing firms’ productivity. These relationships are explored in the context of Africa, where, paradoxically, firms selling abroad must satisfy different market demands than firms that serve only domestic markets.

The authors draw on the World Bank Enterprise Survey to perform a cross-sectional analysis of 4,683 manufacturing firms. These surveys cover the period 2009-2017 and 35 different African countries. The authors define service competence development as co-location with knowledge-intensive business service (KIBS) firms, measured through KIBS density at city level. Signaling is measured through outward-looking competences.

This paper shows that African exporters differ significantly from their non-exporting counterparts in terms of productivity and competences. External service competence generates productivity gains for exporters but has the opposite effect for non-exporters. Results consistent with previous research also show that signaling competences generate productivity gains, but the effect for firms serving domestic markets is stronger than the effect for exporting firms. The authors use paradoxes of learning to interpret these results.

This study detects nuances of the African context that increase the understanding of knowledge management in emerging markets. The findings would benefit from confirmation in a longitudinal and causal setting.

African exporting firms should establish mechanisms to develop joint knowledge with external partners (know-with) to enhance their competitiveness, whereas African non-exporters should prioritize building knowledge credibility.

The study develops a novel empirical approach to analyzing firm competences in Africa. It also shows that contextualization of existing knowledge management theories matters, opening a research avenue to test further existing theories in emerging economies.
