The purpose of this study is to determine whether climate change will
increase or decrease agricultural net revenue in Japan as a whole. This study
conducts the first Ricardian model analysis of this issue and finds that agricultural
net revenue will decrease across Japan by the end of the twenty-first
century. The impacts of climate change are quite different in different regions
of the country;an increase in agricultural net revenue is predicted in the northern
municipalities, whereas agricultural net revenue is predicted to decline in many
other municipalities.
