In Asia and Africa the poor tend to live in marginal environments where droughts and floods are frequent. Global warming is expected to increase the frequency of these weather-induced perturbations of crop production. Drought tolerance (DT) has been one of the most difficult traits to improve in...

This paper investigates the pricing and vertical organization of differentiated products under imperfect competition. In a multiproduct context, a Cournot model is used to examine how substitution/complementarity relationships among products and vertical structures can affect the exercise of...

The purpose of the research in this paper is to investigate the impact of differentiated vertical strategies by agricultural biotechnology firms in the U.S. cottonseed market. The model advances the measurement of industry concentration to consider substitution/complementarity relationships...
