My research uses economics to inform and improve the food system, especially in Africa.  I began with a focus on markets and trade, and have more recently focused on innovation and information.  A narrative record of USDA-funded research at Purdue from 1998 to 2010 is available through my annual reports in CRIS.

Long-term topics (with links to papers and other pages on this site)
  • The market for infant foods, leading to quality certification as a way to improve nutrition by lowering the cost of the high-density complementary foods needed during the crucial period from 6 to 24 months of age.
  • Prizes and contest design, in search of more effective incentives for innovation and performance in agriculture, food and nutrition.  My work in this domain tests how winner-take-all prizes for best performance differ from other incentives, such as shared prizes offered in proportion to incremental improvements.
