Building A Better Rat Trap: Technological Innovation, Human Capital And The Irula

This paper follows Sethu Sethunarayanan, Director of the non-profit Center for the Development of Disadvantaged People (CDDP), which is dedicated to the improvement of the Irula tribe in rural villages of southeast India. The Irulas specialize in catching rats, an activity which provides the bulk of their income and food. Following a routine visit to a local village, Sethu recognized an opportunity for a "Better rat trap" to aid the Irula rat catchers. With feedback from rat catchers, Sethu developed an innovative new trap. His innovation won the prestigious Global Development Marketplace award from the World Bank which provided the funding necessary to commercialize the new technology.
