We study post-harvest decisions among Tanzanian rice farmers. Risk and time preference experiments are used to understand post-harvest decisions. In particular, we investigate storage and processing decisions, which according to our study can increase income by more than 50 per cent, but also introduce risk and time delays. Experimentally elicited risk and time preferences are statistically significant in explaining these post-harvest decisions. Impatient farmers are less likely to store paddy, and risk-averse farmers are less likely both to process and store paddy for future sales. Also, structural factors, such as milling costs, transportation costs and storage losses, influence the post-harvest choices.

小农稻米农户收获后的决定：偏好和结构性因素

我们研究坦桑尼亚稻农之间的收获后决策。风险和时间偏好实验用于了解收获后的决策。特别是，我们调查了存储和处理决策，根据我们的研究，这些决策可以使收入增加50％以上，但同时也会带来风险和时间延迟。实验得出的风险和时间偏好在解释这些收获后的决定方面具有统计学意义。不耐烦的农民不太可能存储稻米，而规避风险的农民则不太可能为未来的销售而加工和存储稻米。而且，诸如碾磨成本，运输成本和存储损失之类的结构因素也会影响收获后的选择。
