Learning by Doing and Learning from Others: Human Capital and Technical Change in Agriculture
利用印度农村家庭面板数据，研究干中学和知识溢出对高产品种采用和盈利的影响，发现经验不足是采用障碍，自身和邻居经验能提高盈利，但农民未充分考虑学习的村庄回报。
Household-level panel data from a nationally representative sample of rural Indian households describing the adoption and profitability of high-yielding seed varieties (HYVs) associated with the Green Revolution are used to test the implications of a model incorporating learning by doing and learning spillovers. The estimates indicate that imperfect knowledge about the management of the new seeds was a significant barrier to adoption; this barrier diminished as farmer experience with the new technologies increased; own experience and neighbors' experience with HYVs significantly increased HYV profitability; and farmers do not fully incorporate the village returns to learning in making adoption decisions.
