Rational Underdevelopment*
研究了一个两区域两部门模型，发现技术变革可能惠及领先或落后地区，而区域间转移支付通过提高工资降低落后地区采用新技术的机会，导致其理性选择保持欠发达状态，解释了意大利南部等地区持续接受补贴的现象。
Abstract We propose a two‐region two‐sector model of uneven development, where technological change benefits either the lagging or the leading region. In this framework interregional transfers may lead to persistent underdevelopment; by raising wages, transfers reduce the chance of the backward region adopting a new technology and taking off. Due to uncertainty about which region benefits from technological change, the backward region may rationally choose to remain underdeveloped, while the advanced region continues to pay transfers. The model provides a rationale for cases, such as Italy's Mezzogiorno , where the same rich region subsidizes the same poor region on a continuous basis.
