本文探讨了政府资助的推广计划的有效性。农场一级的数据被用来评估乳制品讨论小组的经济影响，这是一种常见的参与式推广方法。评估的重点是讨论组的参与者是否提高了农场的利润，这是估计与内生转换回归模型。这种方法控制自我选择的偏见，由于未观察到的特点，如农民的能力，可能会影响参与和农场的盈利能力。在控制了这种潜在的偏见，我们发现，讨论组成员的经济回报是积极的，从而支持政府的目标，招收更多的农民在讨论组。
This article examines the effectiveness of a government funded extension programme. Farm-level data are used to assess the economic impact of dairy discussion groups, a common participatory extension method. The evaluation focuses on whether discussion group participants have improved farm profits, which is estimated with an endogenous switching regression model. This method controls for self-selection bias due to unobserved characteristics, such as the farmer’s ability, that may affect both participation and farm profitability. After controlling for this potential bias, we find that the economic returns to discussion group membership are positive, thus supporting government targets to enrol more farmers in discussion groups.
