Abstract

This paper investigates the impacts of research investment on wheat production. A two-way error component random effect model was estimated using panel data to examine the effects of research investment on mean yield and yield variance. Results show that, for the time period between 1974 and 1995, research investment enhanced yield stability but had no significant impact on mean yield. Key words: yield, yield variance, research investment.
