Teorema de Coase na Prática: O Caso do Mel Azul

Beekeepers in northeastern France have been alarmed to find their bees producing honey in unnatural shades of green and blue. The beekeepers believe the source of the problem is a biogas plant close to Ribeauville in Alsace. It is thought the bees have been eating the sugary waste from M&Ms, small chocolates in brightly-coloured shells. The plant operator said it regretted the situation and had put in place a procedure to stop it happening again.
