The principal objective of the realized study is to evaluate the economic importance of the behavioral interactions which emerge from managed and wild bees, called bees’ complementarity in arable crop farms. A particular emphasis was placed on examining how the economic importance of bees’ complementarity should affect the public policy regulation ...
