Why do our strategy theories fail when confronted with the realities of one of Africa’s most essential informal businesses – minibus taxis? Can a drop in interest rates reduce speeding and crashes? How is the government free-riding on the work (and risk) of taxi entrepreneurs?

In this episode of the Our Long Walk podcast, Johan Fourie and Jonathan Schoots speak with Christopher Eaglin, assistant professor in the strategy area at Duke University’s Fuqua School of Business. Before academia he worked with non-profits, large firms and, crucially, South Africa’s least understood industry: minibus taxis.

What advantages did cowrie shells and beads have over coins in Africa? Is mobile money a revolution, or just the latest chapter in Africa's long history of monetary innovation?

In this episode, Johan Fourie and Jonathan Schoots speak to historian Karin Pallaver about the long history of money in Africa. Karin works at the intersection of economic history, anthropology and archaeology, tracing how shells, beads, metal and paper – and now pixels – have carried value and power across the continent.

Karin Pallaver is Associate Professor of African History at the University of Bologna. She previously worked as a researcher in the Coins and Medals Department at the British Museum in London.

What can we learn from uncertainty? How can using beans help with measuring uncertainty? And are we really living in unusually uncertain times?

In this episode of the Our Long Walk podcast, my co-host Johan Fourie and Jonathan Schoots speak with Jenny Trinitapoli, Professor of Sociology at the University of Chicago. Since 2008 she has led Tsogolo la Thanzi (TLT), a landmark longitudinal study of young adults in Balaka, southern Malawi, following the same respondents for more than a decade as they navigate relationships, sex and childbearing amid a severe AIDS epidemic.

Demographers love tidy bins; cross-national datasets demand them. Yet some domains are genuinely uncertain. Early in Jenny’s Malawi work, Likert-scale questions about HIV risk generated high rates of ‘don’t know’ and outright refusals. Rather than throw those away, the TLT team designed questions to measure uncertainty.

Some of Jenny’s mentioned work:

An Epidemic of Uncertainty

The Flexibility of Fertility Preferences in a Context of Uncertainty
