Policy evaluation and mechanism design on farmland transactions

我们发现，日本农民仍然对“ie”和“community”有传统的偏好，这可能会阻碍耕地的集中。另一方面，一定比例的农户对交换地块整理破碎地块持积极态度。农地改善计划刺激了核心机械工程外判，但没有刺激购买或租用农地。基于模拟分析，我们发现农地细碎化不能通过自愿换地来解决。然而，集中的集体交换可以实现近乎完美的农地整理。

We found that Japanese farmers still hold traditional preferences on “ie” and community, which may hinder the concentration of farmland. On the other hand, certain fraction of farmers is positive in exchanging plots to consolidate fragmented plots.Farmland Improvement Projects stimulated outsourcing of core machinery works but not purchase or rental of farmland.Based on a simulation analyses, we found that farmland fragmentation cannot be resolved through voluntary plot-exchange. However, a centralized, collective exchange can achieve nearly perfect farmland consolidation.
