To do so, we used VAR modeling, the Granger causality test and impulse response function analysis. The estimation results revealed that human capital in Chad contributes positively to economic growth through the "secondary education" variable. Considering the effect of human capital on growth, investment in education, particularly primary and higher education, will increase economic growth in the long term.enHuman capital; Economic growth; VAR Modeling; ChadArticle
