CONCLUSION
With the shift of grocery shopping from traditional to online
environment, consumer logistics that shoppers conduct
themselves has been done by e-grocers. Consequently the
principal-agent relationship is built between online shoppers
and e-grocers by virtue of the information asymmetry. Above
all, this paper deals with the principal-agent problem in terms of
online shoppers, and then it is explained by using
principal-agent theory and a mathematical model is established.
Finally, the solutions are put forward to avoid the moral hazard
of e-grocers
In addition, when e-grocers outsource consumer logistics to
TPL, a multi-class principal-agent problem comes into being
among online shoppers, e-grocers and TPL, and so arise such
problems as quality evaluation of consumer logistics, each of
which merits further study.
