Interactive research tools I have built with AI from public data: the design, the questions and the checking are mine, the code is on GitHub, and each site documents its sources so that any chart or claim can be re-run. The textbook experiments, including The African Economy and its data tools, are listed on their own page.

the global monetary system, measured · launched October 2026, in development

Three layers: the hierarchy of money (what the dollar costs and who can borrow it when it runs short), the dollar's transaction cycle (pricing, financing, risk transfer, payment, reinvestment) and the statecraft toolbox. It measures the past and makes no forecasts. The data companion to
