The American Bee Journal is filled with discussions of colony collapse disorder. It affects the bottom line of beekeepers, as cattle ranchers have to deal with diseases that afflict cattle. Consumers didn't worry about this at all; it's utterly negligible in the price of food they purchase and the availability of food.
Wally Thurman of North Carolina State University and PERC talks with EconTalk host Russ Roberts about the world of bees, beekeepers, and the market for pollination. Thurman describes how farmers hire beekeepers to pollinate their crops and how that market keeps improving crop yields and producing honey. Thurman then discusses how beekeepers have responded to Colony Collapse Disorder--a not fully understood phenomenon where colonies disband, dramatically reducing the number of bees. The discussion closes with the history of bee pollination as an example of a reciprocal externality and how Coase's insight helps understand how the pollination market works.
