Since the population inflow to rural areas has been decreasing, farming successions are facing
a serious difficulty. In response to this, the Korean government has implemented a gift tax
reduction for farmers as a counter-measure. However, there has been not much research on the
policy effects on gift tax reduction on farmland. In this study, we analyzed the effects of the
gift tax reduction policy using a generalized propensity score approach. The generalized
propensity score approach has the advantage of being able to consider the level of treatment,
unlike a standard propensity score matching. We found that this policy has the positive effects
on increasing the inflow of farmers, reducing the average age of farmers, and reducing the Gini
coefficient for farmland in each region (which reflects an increase in equity of farmland).
Specifically, from 2016 to 2019, we found that the increasing effect of 10.3 households by each
region, the decreasing effect of 0.12 years old of farmers, and the reducing effect of the Gini
coefficient of 0.05 in each region.
