Utilizing a multi-period cooperative game model, we propose an optimal
strategy of trade between the market economy of South Korea and the c
entrally-planned economy of North Korea. In the unique context of the
Korean situation, i.e. two Koreas' announced goal of eventual reunific
ation, we define a total welfare loss function and find an optimal str
ategy for inter-Korea trade that should minimize total welfare losses
for the Korean peninsula as a whole.
